In the 1960s and 70s, when vehicles had distributors, carburetors and mechanical ignition, tune-ups were necessary about every 35,000 miles or so. Those days are long gone, and today’s vehicles are more low-maintenance than ever when it comes to tune-ups. So what does a “tune-up” even involve today? First off, consider that on modern vehicles, spark plugs only need to be replaced at about the 100,000 mile mark. It’s really not necessary to replace them before that point; on many vehicles, changing plugs is a difficult job that can equate to many hours of labor. Since today’s vehicles use processors to govern fuel metering, ignition timing, transmission shift points, emissions and other variables, our starting point for any performance issue is to connect a code reader and troubleshoot what’s going on by obtaining the trouble codes stored in the engine computer. The codes give us the information we need to look at the problem from different angles and determine what caused the code to register in the first place and make the right calls on what to repair or replace. Your dashboard Check Engine light is designed to light up when a trouble code is stored in the computer, but sometimes “pending” codes can be stored without lighting up that indicator. Other items on a tune-up today might include: --Replacing the air filter --Replacing the fuel filter(s) --Checking belts and hoses --Replacing the coil-on-plug packs that supply voltage to the spark plugs --Checking the battery, cables, terminals and charging system --Checking or replacing the engine’s oxygen sensor(s) --Checking the exhaust and emissions system While we’re under the hood, we’ll perform a thorough inspection for wear and tear on other parts of the vehicle. This is the kind of preventive maintenance that can head off problems before they worsen. At Auto Express of Sacramento, you can count on a thorough and accurate tune-up and straight talk about whatever issues your vehicle might have, with no jargon or shop talk. It’s the way we do things at Auto Express of Sacramento – honest and straightforward, every time. It’s the kind of personalized and honest service that our loyal customers in the Sacramento area have come to expect from us. Got concerns about your vehicle’s performance?

So lately you’ve noticed that your brakes “feel” different and are making some noises. In many cases, you may hear a clicking noise that increases with speed, a squealing or groaning noise or a metal-to-metal grinding sound. These aren’t the only signs, however, that your brakes might need service. In fact, with the hard ceramic or semimetallic material of newer brake pads, a certain amount of noise isn’t unusual. Other symptoms can include: -Steering wheel pulls to one side while braking -Shake or pulsation through pedal or steering wheel while braking -Excessive brake pedal travel -Brake pedal feels “soft” or “spongy” underfoot -Longer stopping distances These are all signs that shouldn’t be ignored, and should be serviced by professionals soon!  We’ll start with a test drive, then pull off the wheels and have a closer look at the problem. In most cases, it’s worn brake pads that are at fault. Brake pads can last 40-60,000 miles and it can be hard to notice when brake pads have worn to a point where they need service. One thing is for certain, though – a metal-to-metal grinding noise is bad news. It means that either your brakes have worn to the point where the wear indicators are dragging on the rotors, or the pads have worn down to their metal backing plates. Not all brake pads are created equal. Cheaper pads simply will not wear and last as long as good-quality pads. At Auto Express of Sacramento, we use the same pads you’ll find on police cars, ambulances and other vehicles where brake performance is crucial, and that’s what you can depend on with us. Note that pads aren’t always the problem. Sometimes there can be issues with the brake calipers, the rotors, vacuum problems or brake lines. That’s why it’s so important that your brakes be serviced by trained and certified professionals. Brake problems? Make an appointment with us today!

You turn on your A/C and it seems like it's blowing air that's barely cooler than the hot air outside. Or, it blows cool-ish air while you're moving, only to have it blow warm air again when you come to a stop. Why is this happening? There can be several reasons this happens. People tend to think that low refrigerant level is the be-all and end-all for this problem, and usually that's correct. It's normal for the system to lose about five percent of its Freon over a year's time, making an a/c recharge a regular part of spring maintenance. If it's losing Freon quickly, though, it has to be escaping from somewhere. We recommend have the system checked for mechanical problems or leaks. Leaks can occur at the compressor, seals, lines, the condenser, evaporator or really anywhere in the A/C's closed-loop system. Overpressurizing the system by adding too much Freon can lead to more problems, causing tiny O rings to leak or causing other parts to fail. Buying unnecessary parts or over adding Freon can be costly, which is why it's important to be certain where the problem lies before going any farther. At Auto Express of Sacramento, CA, we use the Bacharach detection system which can detect the tiniest of pin holes and drops in system pressure. While refrigerant contains a fluorescent dye which helps detect leaks, the Bacharach system has a higher degree of accuracy and can quickly help pin down problems. This will tell us if everything is in working order or needs attention. It's important to remember that Freon refrigerant also contains a light oil which keeps the compressor lubricated. If you continually run the system with an insufficient amount of Freon, it can destroy the compressor by depriving it of lubrication -- and in some cases, the compressor can come apart and send fragments of metal through the rest of the system, effectively causing much bigger problems.  At Auto Express of Sacramento, we're certified and experienced in A/C service and repair, and we back all our work with a guarantee. Don't suffer through the hot months in a stuffy car -- make an appointment with us today!

It's common knowledge that California emissions standards for vehicles are pretty strict. These are a few of the questions we hear regularly at Auto Express Sacramento: Does every vehicle have to have a smog test? Yes, every vehicle registered in the state of California is required to have a state-authorized smog test. This is emissions testing, and all vehicles must comply. All vehicles are required to have a state mandated smog test. This is emission related and must be in compliance to operate on the highway. Does my Check Engine light have something to do with a smog test? Part of the engine control computer's job is to regulate engine emissions, and it illuminates the Check Engine light if there's a problem. If the Check Engine light comes on and goes off again intermittently, or even if you reset the computer and the light comes back on, there could be an emission problem. Smog testing involves scanning your vehicle's computer for trouble codes, for a true depiction of what is going on inside your vehicle's engine. Even if you have the Check Engine light reset, the computer will still indicate a problem.. You can’t fool the system, which is why it should be maintained by a professional. What's involved in a smog test? During a Smog test the vehicle is tested for compliance; if tailpipe readings and the computer show no problems, your vehicle passes. If the vehicle fails, then the problem must be corrected and inspected again. The vehicle is non-compliant until it passes. What do I do if I fail a Smog test? If you the vehicle fails a smog test, we need to track down the problem that caused the failure and address it in order to become compliant. If the vehicle was tested at our facility, we will diagnose the problem and determine what's needed to correct it. If the vehicle was tested elsewhere, we will look to see why it was failed and take care of the problem. An inspection will be done to ensure no other issues are going on at the same time. Often a vehicle may code or fail emissions, but the actual problem might be more complex. For instance, the computer might indicate a bad O2 sensor; however, the problem could be a broken wire or something more. The code just gives us a place to start and we go from there. Smog testing facilities must have a license to test, however, the state mandates a special, separate license to perform the repair work. We are ASE certified with a specialty in emissions-related issues.  At Auto Express Sacramento we have been repairing emission for over 26 years in the same location. All work is backed by our guarantee. Diagnostic price on the site. Let us make smog testing and compliance easy for you. We will walk you through every step to keep you on the road longer.

Now, really…have you ever known anything that just got better on its own, with you doing nothing about it? Probably not! Your car’s brakes work something like the handbrakes on a bicycle. When you press the brake pedal, a piston moves inside the master cylinder reservoir, sending hydraulic pressure through the brake lines to the wheel calipers. The wheel calipers enclose the smooth steel rotors , and another piston forces two brake pads of friction material against the rotor, causing enough drag to slow and stop it. Friction material is semimetallic or ceramic and wears very slowly – brake pads typically last 40-60,000 miles. As a result, it can be hard to tell when brakes are becoming significantly worn. These are all signs you need brake replacement soon, though… Pronounced pull to one side while braking Excessive brake pedal travel Pulsation through brake pedal while braking Brake pedal slowly goes to floor while holding car at a stop, in gear Longer stopping distances Tendency for one or more wheels to lock up and skid while braking Squeal, groan or metallic grinding noise while braking Of all the above, the metallic grinding noise is the worst sign, by far, and it means that your brake repair costs are about to go up. It means that the brake pads are worn down to their steel backing plates and rivets; all the braking effect you’re getting is from metal-on-metal as the rivets dig into the smooth steel surface of the rotors. A routine brake job just got a lot more expensive, as you’re now going to have to replace the rotors…not to mention that your car is very unsafe until you get the repairs done! The moral? Don’t put off your brake service unless you are just dying to spend a lot more money on brake repair costs. We know you’ve got a lot of choices when it comes to brake repair shops, and we hope you’ll come to Auto Express for brake replacement in Sacramento. Make an appointment with us today!

If you’ve got a health problem that’s troubling you – let’s say your blood pressure is consistently too high, your knee hurts like crazy or you’re having dizzy spells – chances are you’ll go see a doctor for it, right? Maybe it’s not much of anything, or maybe it’s something serious, but there’s one thing for certain – it isn’t just going to get better on its own, and it will most likely just get worse if you put it off. It’d be great if we had the same sort of diligence about keeping our vehicles maintained, but too often we just don’t. We tend to slam the hood and forget about it, and take things for granted for far too long, far too often. Brakes wear very slowly. The friction material on your brake pads can easily last 40-60,000 miles, with the right driving habits. Because they wear down so slowly, it’s easy to not notice signs of wear as they slowly develop: · Car pulls noticeably to one side while braking · Pulsating sensation through brake pedal · One or more wheels tends to lock up and skid · Longer stopping distances · Excessive brake pedal travel before brakes engage · Brake pedal slowly goes to the floor while holding the vehicle stopped and in gear · Screeching, squealing or grinding noises This is where we come to the “repair or replace” dilemma of the title. Disc brakes are comprised of smooth steel rotors, to which your wheels are bolted. A caliper encloses the rotor, and when you step on the brakes, two brake pads grip the rotor and slow the car down in much the same fashion as handbrakes on a bicycle. If you address brake problems early, it’s not a big deal…not much more than just replacing the brake pads. But if you let them go too long, the friction material of the pads will wear all the way down to the pads’ backing plates. If you hear a metal-to-metal grinding noise while braking, that means that all the braking effect you have is coming from the metal backing plates and rivets digging into the smooth steel surface of the brake rotors. At that point, your simple brake job has just about doubled in price; the rotors will be ruined and in need of replacement along with the pads. Not only is this more costly, it’s also extremely dangerous…as you’ve probably realized by now, due to the difficulty of trying to bring your vehicle to a stop. Because brake wear is so gradual, it’s important to keep tabs on it. Don’t let your brakes go more than six months without an inspection of the rotors, the pads and the entire brake system. At Auto Express of Sacramento, CA, brake repair is a big part of what we do. Our ASE-certified technicians are trained and experienced with all sorts of brake repair for just about any car, minivan, light truck, SUV or crossover on the road.

At Auto Express in Sacramento, CA, we occasionally run across customers who are a little confused about timing belts and what they actually do. We’d like to take a little time to clear that up… Q: Is the timing belt the same as the serpentine belt? A: In a word, no. Older vehicles had multiple belts to drive the water pump, power steering pump, air conditioning compressor and other accessories. In the 90s, the serpentine belt was introduced; the serpentine belt is a much longer belt that loops around to drive all the accessories at once. This saves parasitic drag on the engine and saves space under the hood, since the accessories and multiple belts don’t have to all be offset from each other. The timing belt, on the other hand, is concealed under the engine’s front cover and isn’t visible. Q: What does the timing belt do?  A:The internal combustion engine’s bottom end consists of pistons, connecting rods and a crankshaft. The pistons are driven down when the spark plugs detonate explosions of fuel/air inside the cylinders and generate power. The upper end consists of valves that supply fuel/air and then allow the spent exhaust gases to be expelled. The valves are opened by the lobes of a camshaft and closed again by their own springs. The timing belt, then, is what connects the upper end and lower end of the engine (or, the camshaft and crank) and allows the valves to work in sync with the pistons for the four strokes of the combustion process. Older engine designs used a bicycle-style chain rather than a belt, and many still do; timing chains generally last the entire life cycle of the vehicle.. Q: Why is it so important to change the belt at the manufacturer’s specified interval? A: The timing belt, like any other elastic belt, will stretch and eventually fail over time. If the pistons and valves suddenly go out of sync with each other, that means that the pistons are traveling upward in the cylinder at a moment when exhaust or intake valves are open. The pistons’ crowns will crash into the opened valves, bending them, punching holes in the pistons, bending the pistons’ connecting rods and generally wrecking the engine’s internals. Some engines are “non-interference” engines, specifically designed to prevent this from happening, but many aren’t. That’s why if the manufacturer says to change the engine at 60,000 miles, every mile past that is borrowed time. Q: How involved is it to change the timing belt? A: It’s a fairly big job. It requires removing accessories, often removing the radiator, cooling fan and hoses, and the engine’s front timing cover. On about 60 percent of engines, the water pump is also driven by the timing belt. Many technicians will advise replacing the water pump as well at that time, since everything’s already disassembled. It’s also advisable to replace the belt’s pulleys and tensioner at the same time; the tensioner, in particular, can wear out and seize, causing the timing belt to jump from its pulleys and causing major engine damage. Q: Is there a way to check for wear on the timing belt? A: Not really. “Inspecting” the belt will usually mean disassembly, at which point you may as well just go ahead and replace it. Sometimes you might hear a rattle or squeak from the front end of the engine, but more often than not the belt will just fail without warning. A car that has a broken timing belt will just make a steady “whirrrrrr” when it cranks, rather than the usual rhythm of an engine that’s trying to start. We hope this clears up any questions you might have about timing belts and their purpose. Check your owner’s manual for manufacturer’s recommendations on timing belt service intervals, then check your odometer. If you’re coming up on the recommended mileage for a timing belt change, don’t put it off this important auto maintenance detail. Give us a call at Auto Express Sacramento and make an appointment!

At Auto Express in Sacramento, CA, we sometimes see customers who have questions about tune-ups. Today, we’re hoping to clear up a few of them: Q: How often does a tune-up need to be performed? A: Not nearly as often as they did 30 or 40 years ago. In the 60s and 70s, a tune-up involved cleaning the carburetor, setting the idle speed and mixture and possibly rebuilding the carburetor’s internal parts. It was also common to change the spark plugs, replace the plug wires, distributor cap, breaker points and rotor and reset the distributor’s dwell settings. Today, distributors, plug wires, mechanical ignition and carburetors are all things of the past! Q: So what does a tune-up involve today, then? A: A typical tune-up today might include replacing the spark plugs, air filter, fuel filter and cabin air filter. The distributor and plug wires of a generation ago have now been replaced with coil-on-plug packs that deliver spark directly to each plug; sometimes these coil packs will fail and need to be replaced. A technician will hook up a code reader to the engine computer’s diagnostic connector to check for trouble codes. Other than that, the tune-up today might also include a check of all the engine and drivetrain fluids and a thorough examination of hoses and belts. Q: Is the timing belt part of a tune-up? A: No, but the timing belt should be replaced at the manufacturer’s recommended interval. The timing belt coordinates the opening and closing of valves with the rotation of the crankshaft. On many engines, a broken timing belt can mean that the valves and pistons go out of sync with each other; the pistons travel upward in the cylinder and smash into opened valves, effectively ruining the engine. Note also that, rather than a belt, many vehicles still use a timing chain, which is good for the lifetime of the engine. Q: So how often does a tune-up need to be done today? A: Today’s engines are much less maintenance-intensive than cars of a generation ago. The 30,000 mile tune-up of the 60s is now only needed at about every 80,000 or even 100,000 miles. Spark plugs in particular have a much longer service life than they once did. If you’re noticing problems like lack of power, rough running, an illuminated Check Engine light, rough idle, a tendency to stumble or stall or a drop in fuel economy, it might be time for a tune-up on your vehicle. Don’t just put up with drivability problems like those -- give us a call at Auto Express in Sacramento, CA, make an appointment and let our techs perform a tune-up on your car!
