The Check Engine Light strikes fear into the hearts of some and is totally ignored by just as many. What it means is a mystery to most drivers. In this article we will be discussing what the check engine light means and how it works, if you would like more information about your check engine light be sure to check with your auto repair professional at Town Hill Auto Service in Bedford PA.
Check engine light degrees
If your vehicle’s check engine light is flashing, that means that something is wrong that could cause severe damage to your engine. Naturally, If your check engine light is flashing, you shouldn’t drive at highway speeds, tow or haul heavy loads. You should get it checked out as soon as possible by a reputable service department.
If the light is glowing steadily, you should keep an eye on it for a day or two. If the light doesn’t go off, schedule an appointment with the staff at Town Hill Auto Sales and Service to get it checked out.
How does it work?
Most of your vehicle’s engine functions are controlled by a computer, not surprisingly, called an engine control computer. The computer is able to adjust the engine parameters to compensate for environmental conditions, engine condition and even the way you drive.
In order to make these adjustments, the computer relies on a network of sensors to provide the necessary data. The computer knows the proper operating range for each sensor. When a sensor reading is out of range the computer runs some tests and may activate the Check Engine Light if it gets a negative or unclear reading.
A simple example is a loose or missing gas cap. This may cause one of the sensors to read out of range. The vehicle’s computer doesn’t know if it’s a serious condition that caused the reading or just a loose gas cap, so it stores a trouble code and turns on the Check Engine Light.
Now when you tighten up the gas cap the sensor readings will be in the correct range. The computer will keep checking on the report for a day or two. Since the bad reading didn’t come up again, it turns off the Check Engine Light. The computer will also try to make adjustments to compensate for some readings. If it can do so, it’ll then turn off the Check Engine Light. If the problem can’t be resolved then the light will remain on and you should get your vehicle looked at by the pros at Town Hill Auto Sales and Service in Bedford PA.

Are you aware of just how important your cooling system is? Coolant/antifreeze circulates around the engine, absorbs heat, and then dissipates that heat into the radiator. Cooling system failure can cause extensive engine damage. This article will deal with a couple of ways a well maintained cooling system can help prolong the life of your vehicle, and be sure to check with your auto repair professional at Town Hill Auto Service in Bedford PA for more info about your cooling system.
Minor coolant leaks
It’s very tempting to put off repairing small cooling system leaks. Topping off the coolant isn’t that big of a deal right? However, there are several problems with doing this.
Coolant is messy, It doesn’t just evaporate away. The resulting puddle is harmful to the environment and toxic to pets.
You need to keep the proper balance of coolant/antifreeze and distilled water to maintain optimal boil and freeze properties, be sure to check with your auto repair professional at Town Hill Auto Service in Bedford for more info about your cooling system.
The cooling system needs to maintain a certain pressure to do its job, and a leak compromises the pressure.
Small leaks can unexpectedly become big leaks that leave you stranded.
Corrosion protection.
Antifreeze/coolant contains a package of anti-corrosion additives. These additives coat internal surfaces throughout the entire cooling system. They protect against oxidation, which can lead to leaks, as well as scale that clogs cooling system components. The protective coating is constantly reacting to chemical compounds created by the extreme heating and cooling cycle the coolant goes through. Over time, the coating is depleted and there is nothing left to protect the exposed metal in the engine and in the other system parts.
This is why your vehicle manufacturer recommends your coolant/antifreeze be changed periodically. Even though your old coolant may seem to be doing a good job of cooling your engine, it leaves the engine exposed to corrosive elements that will damage the system. A good practice is to have a coolant exchange performed whenever you replace a cooling system component. For example, when you put in a new water pump it is not protected with anti-corrosion additives. If your anti-corrosion package is already depleted, the new water pump will immediately be exposed to corrosive elements that will significantly reduce its life cycle. If you change the coolant when the new water pump is installed, it will be protected the first time you start the engine.
