Car Neol Over Heating Problem

If your car is steaming hot than you are very lucky man. If that is taken literally than we have a serious problem. Overheating cars can be a real pain since you can’t go even 100 m without having to stop. To help diagnose and troubleshoot the car let’s get the basic needs out of the way.

Firstly go ahead and check for the amount of coolant or antifreeze in the radiator, if there is any at all. Check out the plastic jar and not only. Get the radiator cap out and have a look. You should see the amount of fluid in the radiator if it is at optimal level.

Be careful, under no circumstances you are to do that when the radiator is hot because you can get serious burns from the hot pressurized steam accumulated inside the radiator. Usually there are about one, one and a half gallons of mixture between cooling agent and water, depending the type of car or truck you own.  If you see absolutely no fluid at all and are forced to add almost a pint of coolant, then you should probably have the radiator and the cooling system checked for leaks. That goes for any visible traces of fluid loss in which you know you have a problem and check for the exact location of the problem.

If there is no sign of leaks or the fluid is at optimum level, then you need to pay attention to a different factor. You need to test the car when in idle or cruising so that you may determine when the problem occurs.

In case of engine overheating when it’s on idle or at a stop, you should know that most cars that have front wheel drive have added to the radiator an electric fan that can be found behind or in front of the radiator. The purpose of the fan is to ease in the airflow to the radiator when the car is moving slow enough so that the wind isn’t enough to cool it any more. The electric fan has a sensor that detects the temperature of the engine and activates when the heat rises over an established parameter. After cooling down the same sensor deactivates it.

In case the air conditioner is activated, the cooling fan is required as the air conditioning compressor heats up the engine. If you’re suspicious that the electric fan might malfunction, you can turn on the air conditioner. The compressor activates and so should the fan, yet still the temperature should remain constant. If it still rises then maybe a good idea is to have the electric fan engine checked. Once again be careful of what fan you check since some cars may have two fans, one for the radiator and the other for the air conditioner called the condenser fan. To supervise the right one, look for the fan that is closer to the middle of the radiator.

If the engine is overheating when you are driving at higher speed, then the inspection turns towards the coolant/antifreeze circulation. At 60 MPH or higher you should have more than enough airflow to the radiator. Think of it like running with your mouth shut. The faster or longer you run, you need a higher quantity of air so you breathe heavier and heavier so that you can maintain the rhythm. So does the water pump, to maintain an optimal temperature, has to pump a large quantity of heated cooling agent into the cooling system.
