The Puzzling Puddle (Leaks Under Vehicle)

Ever notice a little spot of liquid under your vehicle after you've parked in your driveway or garage? It may have been something as simple as water left from air conditioning condensation.  But then again, it could be a sign that there's trouble brewing in one of your vehicle's systems.

You can help your service facility diagnose the problem by getting a little sample of the drip.  At the same time, you may save yourself a tougher clean up task by preventing the leaky fluid from really messing up the driveway or garage floor.  The first thing is to put something under the vehicle. A flattened out cardboard box will do fine.  You may also want to slip a little disposable aluminum tray or pan under it to catch a bit of the fluid.  Chroma and consistency can help a technician quickly figure out what kind of fluid you're dealing with.  You can take your sample with you when you go to your service facility.

Also note how much of the substance is there over what period of time, when you started to notice it and its location relative to the vehicle.  Is it on the passenger's or driver's side? Front, middle or back? Vehicle's have different designs, so where their equipment is located will depend on make and model. 

The leaky fluid will have a certain look to it and consistency.  If it's blue, it may be windshield washer fluid and a sign that your washer fluid tank has a leak.  If it's green, it could be antifreeze.  Orange may mean rusty water or transmission fluid.  Brown? Might be oil.

There should be no leaks in your powertrain if things are maintained properly.  A small leak may not seem like a big deal, but sometimes they can get much bigger quickly.  A coolant leak, for example, may suddenly go from pinhole to flood, draining your cooling system and putting your engine in danger of overheating. 

It is a really good idea to have a professional check out your leaks as soon as you notice them.  And the more clues you can provide, the happier the technician will be as the search for the problem gets underway.

Not So Cool (Air Conditioning Systems)

There's nothing quite like getting in your vehicle on a hot day, switching on the air conditioning and having warm air blow out of the vents.  You may have had no problem for months and then, one day, you are driving around in a sauna. You're hot stuff, but not in a good way!

So what goes wrong when the AC isn't working? It could be a lot of things because the system has many different components.  One thing that's a common cause is the vehicle is low on refrigerant (it used to be called Freon).  If that's the case, it's not as simple as simply adding more.  Sure, it may fix it quickly for a short time, but it's more likely than not that the refrigerant will just leak out again.

The original Freon used in air conditioners was destroying the Earth's ozone layer, so that's not used much any more.  But the one that's currently used also contributes to global warming, so it's important that as little of that escapes as possible.  So a technician will determine if there's a leak in your system, where it is and fix that before adding new refrigerant. 

Your vehicle also has an evaporator or two, and those can fail.  Leaks are often the problem with them as well.  The big component that can go bad is the compressor, often a victim of age, wear or neglect. 

A technician will also check to see that the blower is working correctly.  That's what blows that cool air into the cabin.  Sometimes the motor will fail, a relay will go bad or a fuse will blow.  As you can see, there are lots of different parts involved here! 

The good news is that your vehicle's service facility has the special equipment to recover the refrigerant and check the system's pressure, both vital to properly servicing the air conditioning system.

As with many vehicle components, regular maintenance can go a long way to minimizing problems in the air conditioning system. It can reduce the chance of the compressor having to be replaced, too.  Pretty cool, huh?

Not a Good Vibe (Driveshaft Failure)

When you feel your vehicle vibrating as you're driving down the road, one cause could be something you may not have ever seen: your driveshaft.  It is underneath the vehicle and most drivers don't climb under there to take a look very often.  The driveshaft is a cylindrical part that helps conduct the rotational power from your engine to your drive wheels.  If you have a four-wheel drive vehicle, you may have two driveshafts. 

The drive shaft has bushings, and when they wear out, that's a likely source of the vibrations.  When the bushings are in good condition, they prevent the driveshaft from vibrating.  And if you don't get your vehicle repaired fairly soon after discovering vibrations, they'll continue to get worse and cause other components of the drivetrain to wear out.

The driveshaft is, of course, only one part of the drivetrain.  It includes other parts such as axles, transmission, differentials and joints.  They all work together and need to be maintained properly.  When a driveshaft fails, there can be symptoms other than vibrations.  They include difficulty turning, rattles, clunks and squeaks coming from underneath your vehicle. You may even feel a shudder when you accelerate from a stop.

Driveshafts can fail when they get corroded or damaged by rough roads, curbs and debris. A trained technician with experience working on drivetrains uses specialized equipment that doesn't further damage the drivetrain's other parts.  Sometimes the entire driveshaft will have to be replaced; sometimes the problems can be fixed by replacing individual components. 

Your vehicle's drivetrain was engineered to propel you smoothly down the road.  When time and distance begin to take their toll, have your vehicle looked at by your service facility. They'll know how to properly pinpoint what's causing your problems and restore your vehicle to the reliable, smooth, safe machine its designers worked hard to create.

Fuel for Thought

If you're like most people and drive a gasoline-powered vehicle, you need to be up to speed on its fuel-related components.  They're pretty basic: the fuel, the fuel filter and the fuel pump.

The fuel's the easy part.  You probably gas up your vehicle yourself and, if you're like most drivers, price is a big factor in what you put in your vehicle. Maybe you think it doesn't matter what kind of gasoline you buy, but one major automobile association has found it does make a big difference. 

Their study showed that the additives that are put in different brands can affect your vehicle's performance.  Certain gasoline retailers sell gasoline that meets performance standards called Top Tier.  The detergents used in Top Tier gasoline help protect newer engines from carbon buildup and deposits on intake valves, all things that can affect how smoothly your engine runs, how it accelerates and what kind of fuel economy you get.  You can check online or ask your service advisor where to buy Top Tier gasoline.

Another fairly simple component is the fuel filter. Depending on the age of your vehicle, you either have a separate fuel filter or one that's part of the fuel pump.  The fuel filter keeps the crud out of your engine's fuel injectors.  You'll get a hint that your fuel filter might be clogged if you notice your vehicle won't start, your power isn't what it used to be, your fuel economy is suffering or your Check Engine light is on.

Check with your service advisor to see what your vehicle manufacturer's recommendations are on how often to service your fuel filter.  Regular maintenance can prevent expensive repairs in the future. 

Finally, the most complicated part: the fuel pump.  As you may have guessed, it is the part that gets the gasoline out of the tank and into the engine.  If the fuel pump starts to fail, it can make a clicking or whining noise when your vehicle is running.  Your engine may misfire, lose power while driving or might be hard to start in the morning.  And that Check Engine light might go on.  One thing that helps prolong the life of a fuel pump is keeping your gas tank at least a quarter-tank full at all times.  It helps lubricate and cool the pump.  If you've detected some of the symptoms of fuel pump failure, tell your service advisor.

Knowing a little about your fuel system really can be a gas!

Automotive Tips from Niel's Auto Service: Knowing When Your Timing Belt Should Be Replaced

The timing belt in your engine controls the opening and closing of the intake and exhaust valves. Thousand Oaks drivers need to replace it on a schedule to avoid failure.

Timing belts are very difficult to get to, requiring quite a bit of labor to access. Timing belt replacement is one of the more expensive maintenance services, but the cost at Niel's Auto Service to correct an engine damaged by a broken timing belt is much, much more.

The timing belt has a tensioner to help maintain proper belt tension. The tensioner should be replaced along with the timing belt and any idler pulleys at the vehicle manufacturer’s specified service interval. Your Niel's Auto Service service advisor can help you with the timing belt.

Give us a call.
