Let’s take engine oil. Twenty or thirty years ago, there were just a handful of different weights of oil. The weight of an oil is a scientific measure of its properties, particularly its viscosity or thickness.

It was common in those days to use a lighter weight oil in the winter when it’s cold outside. That way the oil would be able to splash around inside the engine and protect the parts before it was fully warmed up. And a heavier weight oil would be used in the summer. The thicker oil wouldn’t thin out too much in the summer heat and vaporize in the engine.

Modern valve trains have become very complicated with more moving parts and small passages than ever before. The valve train is in the top of the engine, so when the car has been turned off for a while, the oil tends to run down to lower areas and the valve train parts are vulnerable at start-up, before the oil starts circulating.

So new weights of oil have been introduced to meet the engineering specifications of these newer engines.

Manufacturers are recommending specific weights of oil. The recommendation is often printed on the oil fill cap. It’s certainly in the owner’s manual. Of course, your Spring TX auto service center can look it up for you.

It’s more important than ever to have the correct weight of oil. The wrong weight could actually harm the engine.

Other fluids are also becoming more sophisticated. In the last few years new types of transmission, power brake fluid and coolant have all been introduced for some of the same reasons as for engine oil.

In addition, vehicle manufacturers are now using a wider variety of materials in these systems. Looking at the cooling system as an example, it used to be that the parts were all made out of steel or iron and the hoses were rubber. Now, some parts are plastic, aluminum or other materials.

So the anti-corrosion additives contained in the coolant, or anti-freeze, need to be different in order to protect the different materials used to make the cooling system. If you use the wrong coolant that wasn’t formulated to protect your plastic cooling system parts, they could become corroded and fail. And if you’re using the wrong coolant, your cooling system won’t be covered under warrantee. So it’s important to use the right coolant and to not mix different types.

Your owner’s manual or your Spring TX service advisor at C&A Transmission & Auto Repair can make sure you’re using the right type. You may have heard of universal coolant. Universal, or global, coolant can be added to other types without harmful reactions. That’s OK for an emergency top off, but following your manufacturer’s recommendation for your family car or other auto type is always a safe bet.

In the area of brake fluid, there are a couple of new formulations. It’s important to remember that the new ones aren’t better than the old ones. They’re just different formulations for different vehicles. So if your vehicle calls for DOT 3, using DOT 4 or DOT 5 is not an upgrade. Use the recommended formula.

There are fluid formulations for vehicles with higher mileage. These are special engine oil, transmission fluid, and so on that contain additives to condition and restore seals and gaskets in older engines.

They’re fine to use as long as they’re a variant of the proper fluid. In other words you can use a high mileage engine oil as long as it’s also the correct weight recommended by the manufacturer. Same goes for transmission fluid; as long as it’s the right type for your transmission.

Cool Breeze: Air Conditioning Service At C&A Transmission & Auto Repair In Spring

Most TX motorists know that their vehicles need regular preventive maintenance like changing the oil and filters, rotating the tires and refilling the washer fluid. But did you know that your air conditioning system needs routine maintenance as well? Taking care of your air conditioning system can extend its life and prevent costly repair bills.

Why is it important for Houston motorists to get routine maintenance on their air conditioning system? First, the refrigerant contains an added lubricant. As the refrigerant circulates through the air conditioning system, its parts are lubricated. This constant lubrication keeps the parts functioning well. But over time, this lubricant is used up, and without it, the parts will eventually seize up and fail.

Spring folks should understand, however, that the air conditioner will continue to pump out cool air even without the lubricant, so you won’t know the system is sick until it actually dies. So good car care includes regularly checking the refrigerant and lubricant in your family car air conditioning system and replacing it if needed.

The second reason your air conditioning system needs preventive maintenance is that air and water can get into the system. Air, water and the contaminants they contain will reduce the efficiency of the air conditioning system and can cause corrosion of the system’s parts. Keeping the air conditioning system clean is an essential practice and will extend its life and keep you from losing your cool on hot Houston days.

How often should you get a routine car air conditioner inspection? It varies from vehicle to vehicle. Check your owner’s manual for the vehicle manufacturer’s recommendation.

Here’s a good piece of auto advice for TX auto owners that will extend the life of their air conditioning systems: You should run your air conditioner in the winter every once in a while. This circulates the refrigerant, which lubricates the seals. That way, they won’t dry out during cold Spring weather.

Your air conditioning system doesn’t just cool the air in your family car; it dries it out as well. So if you have trouble with a foggy windshield, flip on your air conditioning on the defrost setting. You may be surprised at how quickly it takes care of the problem. Of course, some vehicles can’t run the air conditioner and defroster at the same time; you should check your owner’s manual or with the car maker if you are uncertain whether this feature works in your car or not.

So, after learning about preventive maintenance for your A/C, you might now be wondering if your air conditioner is in trouble. Two early warning signs of a failing air conditioner are (1) the air just isn’t getting as cold as it used to and (2) there’s a strange noise when the air conditioner turns on. If you notice either of these symptoms in your family car, you should bring it to C&A Transmission & Auto Repair in Spring as soon as possible.

Just some good auto advice to keep you cool in Houston and keep you on the road!

Drive Train – What You Need to Know In Spring

One Spring automotive service issue that doesn’t get much attention is driveline service. Drivelines don’t get talked about very much around Houston, but they’re very essential. First let’s define what the driveline is:

Taking a small step back, the power plant is comprised of the engine and transmission. The driveline starts there and includes all of the components that transfer power from the transmission to the wheels.

That’s not really a lot of components, but they handle the full force of the engine. Without the driveline you’re not moving. So Spring motorists need to take good care of it. The driveline components differ depending on whether your vehicle has front wheel drive, rear wheel drive, all wheel drive or four wheel drive. For purposes of our discussion, we’re going to have to oversimplify a bit.

If you are ready to have your drive train looked at, give us a call:

Let’s start with front wheel drive. The point where the transmission stops and the driveline begins is a little blurred with front wheel drive because the transaxle houses both the transmission function and the differential function. The half shafts that send power to each front wheel, come out of the transaxle. The shaft is connected to the wheel by a constant velocity, or CV, joint. The CV joint is protected from dirt and water by an airtight, flexible rubber boot.

So, C&A Transmission & Auto Repair driveline service would include properly servicing the transaxle and inspecting the cv boot to see if it’s torn or loose. If it is, it needs to be replaced and the CV joint inspected for damage. Repairs may be in order. Besides visual damage to the airtight CV boot, you might hear a clicking noise when turning. Recommended maintenance for the transaxle and CV joints will be spelled out in your owner’s manual or check with your personable C&A Transmission & Auto Repair tech.

On to rear wheel drive. The driveline for a rear wheel drive vehicle starts with the driveshaft – that long tube that connects the transmission with the differential on the rear axle. Some vehicles in Spring have a two piece drive shaft. The shafts are connected to the transmission and the differential with big universal joints. Most Spring motorists have probably heard the term ‘u-joints‘. These joints can wear out, just like the CV joints in front wheel drive vehicles. You may hear some clunking or feel a jolt when shifting into drive or reverse – if you do, get your driveline inspected at C&A Transmission & Auto Repair in Spring.

The differential on the rear axle sends power out to each rear wheel through half shafts in the axle. The differential fluid needs to be drained periodically and replaced with clean fluid. When the seal on the end of the axle is damaged or leaks, the axle will need to be serviced. The routine maintenance item here is differential service. Be sure to check your owner’s manual or Spring service advisor for intervals.

Now let’s go on to all wheel drive. Remember that the difference between all wheel drive and four wheel drive is that an all wheel drive vehicle is essentially providing power to all of the wheels all of the time. The family car may be able to shift more of the power to the front or to the back depending on where you need traction. All wheel drive vehicles are designed to work well on dry pavement. Even some high-end sports cars from makers like Lamborghini and Porsche have all wheel drive.

Some all wheel drive vehicles are designed to work well off-road in Spring, but all hard-core rock crawlers are four wheel drive. These guys thrive in mud, sand, rocks and hills – but they don’t work well on dry pavement when they’re in four wheel drive. So they have the option to shift to rear wheel drive only on dry pavement.

Most all-wheel drive vehicles are very similar to front wheel drive when it comes to the front end. They also have a center differential that transfers power to the rear differential. Connecting it all is a shaft from the transaxle to the center differential and another from the center differential to the rear differential. So all of the normal front wheel drive service is important as well as service to the center and rear differentials.

Four wheel drive can be thought of as a rear wheel drive vehicle that can also send power to the front axle. There’s a transfer case in the middle of the vehicle that can be shifted to send power through a drive shaft to a differential on the front axle. So Spring auto owners need differential service for the front and rear differentials and for the transfer case as well.

The bottom line for Spring auto owners is that the maintenance schedules are in your owner’s manual. Your Spring service advisor can answer any questions you’ve got. If this is the first time you’ve heard some of this stuff – it’s time to ask someone at C&A Transmission & Auto Repair if any of it needs to be done now.

Gear Up: Transmission Service at C&A Transmission & Auto Repair in Spring

The transmission system in your vehicle allows you to change gears. Lower gears are power gears. They get your vehicle moving and get it up hills. Higher gears get the vehicle up to speed and get it rolling faster. If you have a standard transmission, then you have to do the work of shifting gears yourself. But with an automatic transmission, the vehicle shifts gears on its own. It automatically starts out in low gear and automatically shifts to high gears as it gets rolling. Again, it will automatically shift to a lower gear to climb hills or when you need a burst of speed.

How does it know when to change gears? Today’s automatic transmissions are computer-controlled. The computer gathers information about what the vehicle is doing, and changes the gears as needed.

Automatic transmissions are becoming more sophisticated all the time. More gears, or “speeds” are being added. Almost all vehicles have four at least speeds. Five or six is common. Some automobile manufacturers are even increasing to seven or eight – up to ten. Adding gears has a lot of advantages for Spring car owners: it improves MPG and increases performance.

But there is a drawback for Spring drivers: more gears equals more parts and a more complex transmission system. Plus, all those parts need to fit into the same space as older, less complex transmissions. This means that today’s transmissions are engineered to much tighter tolerances. In other words, they demand meticulous care from Spring auto owners. Transmissions are designed for durability. But that durability can be compromised if they aren’t given proper care.

That’s why changing transmission fluid is such an important part of preventive maintenance for Spring motorists. Transmission fluid lubricates the transmission and keeps it in good working order. But if the fluid runs low, transmission parts will wear out quickly or suffer expensive damage due to increased friction. The transmission can even fail.

Dirty transmission fluid can clog the small passageways in the transmission, blocking lubricant from reaching all of its parts. Again, this can lead to increased wear, damage or failure.

New transmissions aren’t cheap. Repairing them isn’t cheap either. But changing transmission fluid is fairly inexpensive for Spring auto owners at C&A Transmission & Auto Repair. That’s why responsible car care includes maintenance on the transmission system at C&A Transmission & Auto Repair. It doesn’t take a genius to figure out that periodic fluid changes aren’t just good auto advice, they actually pay for themselves by preventing costly transmission repairs.
