Cool Running (Water Pump)

Your vehicle is like you in a way.  When it gets hot, it needs to be cooled down.  And one of the key parts to keeping it cool is the water pump.

Now, that's a bit of a misnomer.  It IS a pump, but it's pumping coolant, not pure water.  Cooling off your engine is vital since it builds up heat when it creates power by burning fuel.  Your water pump acts as a way to recirculate that coolant.  It goes through a series of tubes and hoses through the engine where it picks up heat, then is sent off to the radiator to get rid of that heat.  Cooled off, the coolant is recycled through the water pump to start the journey again.

The water pump works by taking mechanical power from the engine, usually from a belt.  Obviously, that belt has to be in good condition and adjusted properly or else the water pump won't be able to do its job.

Here are some things to look for that will signal problems with your water pump.  If your heat gauge is erratic or showing a much higher than normal temperature, that could be a sign of trouble.  Another is if you hear a whine under the hood.  And if that gets louder when you go faster, get it checked right away.  You may see steam coming out from under the hood or coolant may be leaking. 

These signs signal that it's time for you to have a technician check to see where the problem is. Some water pumps are powered by a timing belt.  If your vehicle has that design and your timing belt is due for replacement, sometimes it's a good idea to replace the water pump too, even if it's working properly.  That's because the labor to replace the timing belt can be expensive and it may be wise to proactively take care of the water pump while it's disassembled.

Your service advisor will explain the options available and offer the best path to keeping your water pump doing its job.  Your engine's life depends on it.

A Clean Sweep (Fuel Injector Cleaning)

Your vehicle gets its power from burning fuel, usually gasoline, and it counts on something called fuel injectors to send gas to the engine in a spray that is easy to ignite.  It’s a precise operation, and when it’s working well, you have plenty of power and an efficient engine.

But after time, contaminants in the fuel system may prevent the injectors from spraying like they’re supposed to.  They can also shoot contaminants into the engine. 

One sign that could point to dirty fuel injectors is a misfiring engine. Misfires can be caused by several things, so it’s a good idea to bring your vehicle to us so we can trace the cause. Another sign is that your fuel economy has gone downhill or your engine doesn’t have the “pep” it used to.

If we discover that your injectors are clogged or not working the way they should, we can clean them to get rid of those contaminants to restore your engine to its top performance.  When you bring your vehicle to us, we will connect the flushing equipment, flush out the injectors and reassemble the system.

A good time to have fuel injectors inspected is when you bring your vehicle in for routine maintenance.  An oil change is an ideal time to have a technician take a close look at your entire fuel delivery system. 

When you have your fuel injectors cleaned, you may see your mileage go up, your engine performance improve, and your exhaust emissions decrease.

How Your Check Engine Light Works

Have you ever had an experience like this in Millington, NJ? You drive through the one of those automatic car washes. When you get to the end, where the dryer is blowing, your Check Engine light starts flashing!

You fear the worst, but within a block or two, the light stops flashing, but stays on. By the next day, the light is off.

You wonder; "What was going on?" Well, it's actually a good lesson in how the Check Engine light works.

Your air intake system has a sensor that measures how much air is coming through it. When you went under the high-speed dryer, all that air was blasting past the sensor. Your engine computer was saying, there shouldn't be that much air when the engine is just idling. Something's wrong. Whatever's wrong could cause some serious engine damage.

Warning, warning! It flashes the Check Engine light to alert you to take immediate action.

It stopped flashing because once you were out from under the dryer, the airflow returned to normal. Now the engine control computer says the danger is past, but I'm still concerned, I'll keep this light on for now.

Then the Check Engine light goes off in a day or two.

The condition never did recur, so the computer says whatever it was, it's gone now. The danger is past, I'll turn that light off.

Now a flashing Check Engine light is serious. You need to get it into Long Hill Auto Service as soon as possible. But if it stops flashing you can wait a few days, so you have time to see if the problem will clear itself or if you need to get it checked. How does the computer know when to clear itself?

Think of it this way. The engine control computer is the brain that can make adjustments to manage the engine. Things like alter the air-to- fuel mix, spark advance and so on. The computer relies on a series of sensors to get the information it needs to make decisions on what to do.

The computer knows what readings are in a normal range for various conditions. Get out of range, and it logs a trouble code and lights up the Check Engine warning.

The computer will then try to make adjustments if it can. If the computer can't compensate for the problem, the Check Engine light stays on.

The computer logs a trouble code. Some people think the code will tell the technician exactly what's wrong.

Actually, the code will tell the technician what sensor reading is out of parameters. It can't really tell him why, because there could be any number of causes.

Let's say you're feeling hot. You get your heat sensor out – a thermometer – put it under our tongue and in a minute or two you learn that you have a fever of 104 degrees F (40 degrees C).

You know your symptom – a fever – but you don't know what's causing it. Is it the flu, a sinus infection or appendicitis?

You need more information than just that one sensor reading. But it does give you a place to start and narrows down the possible problems.

There are reports on the internet telling you that you can just go down to an auto parts store and get them to read your trouble code or buy a cheap scan tool to do it yourself.

There are two problems with that. First, the computer stores some trouble codes in short term memory and some in permanent memory. Each manufacturer's computer stores generic trouble codes, but they also store codes that are specific to their brand.

A cheap, generic scan tool, like you can buy online or that the auto parts store uses, doesn't have the ability to retrieve long-term storage or manufacturer specific codes. Your Millington, NJ, service center has spent a lot of money on high-end scan tools and software to do a deep retrieval of information from your engine control computer.

The second problem is that once you've got the information, do you know what to do with it? For example, a very common trouble code comes up when the reading on the oxygen sensor is out of whack.

So the common solution is for the auto parts store to sell you a new oxygen sensor — which is not cheap — and send you off on your way. Now your oxygen sensor may indeed have been bad and needed replacing. But the error code could have come from any of a dozen of other problems.

How do you know the right solution? Back to the fever analogy, do you need surgery or an aspirin? Leave it to the pros at Long Hill Auto Service. Give us a call and let us help you resolve your check engine light issue.

Stuck! (Vehicle Door Issues)

This may have happened to you.  You drive somewhere and get out of your vehicle only to try closing the door and it just won't stay closed!  What a helpless feeling.  You can't lock it; you can't leave it like it is. Or, let's say you head down to your vehicle to head out to work in the morning and you can't open the door.  What are you going to do now?

Vehicle doors take a lot of abuse.  They are opened and closed hundreds of times and we expect them to just keep working perfectly all the time.  They do require a bit of tender loving care.  Let's take a look at two different scenarios of stuck doors.

First: the door that won't close.  It's a security issue.  It's also a safety issue.  You can't really safely drive a vehicle with a door that won't close. What if you or a passenger is tossed out?  Sure, some people try to tie a stuck-open door closed or bungee it, but that's dangerous.  It's best to get that vehicle to the service repair facility as soon as you can, and having it towed is the safest way. 

Second: the door that won't open.  There are many reasons this can happen.  Freezing weather is one, a misaligned door is another.  There could be electrical issues.  Corrosion could have broken a part inside the door.  The possibilities, unfortunately, are numerous.

If you can't get into your vehicle's driver's door, with any luck another door might open and you can climb into the driver's seat and head on to the repair facility.  A lot of people may be tempted to try to fix a stuck door themselves, but many wind up causing more damage to the door and have to have a trained technician step in to repair the mess.

One way to minimize the possibility of having a door stick open or closed is to make sure it gets regular maintenance.  Door locks, hinges and latches should be lubricated at certain intervals.  Locks should be kept clean.  While many vehicles now have electronic locks, sometimes an electrical failure in the vehicle or key fob can inadvertently lock you out.  Nearly every vehicle has a mechanical key in case that happens; if you don't know how that works, have your service advisor show you how. 

Also, you technician can make sure your doors are properly aligned and aren't sagging. All of these things can help you keep your doors opening and closing the way they were designed to. Your next trip may "hinge" on your doors being in top condition.
