  • Everything You Need to Know When Your Pontiac Grand Am Overheats When Idling

    Your Pontiac Grand Am overheats when idling if there is not enough coolant in the radiator or there is a malfunctioning fan, radiator, or fan belt. And this can be so frustrating especially if it happens when you\'re stuck in traffic. As you look at the needle on your gauge starts to rise, you can\'t help but panic and get utterly frustrated. It\'s no fun, but this really happens if you fail to check your vehicle regularly. So what to do?

    Take necessary precautions

    Your cooling system plays a major role in keeping the engine cool. So when your engine is about to overheat, the gauge on your dashboard will warn you since it usually measures the temperature of the coolant not the oil. Oil helps to also cool the engine, particularly the countering parts within. But the coolant mixture, which is 50% “coolant” and 50% water in most cases with the “coolant” being a chemical called Ethylene Glycol or EG for short, is the one responsible mainly in keeping the engine from overheating.

    When your engine overheats, you have to use extreme attention when working on the cooling system. The cooling system can cause extreme burns if opened when hot. Use caution when working around hot or rotating engine parts. On cars with electric cooling fans, the cooling fan begins automatically. Keep yourself away from the cooling fan at all times. Radiator flush agents may be an aid in removing scaling from the radiator. Use these as per the manufacturers\' recommendations.

    Conduct a diagnostic test

    You should start your diagnosis with visual inspection. Let your car idle for a bit (keeping an eye on the temperature) and see if your fan is functioning. If it does not work, then you found your problem. It is either the fan relay or the fan motor itself. If your fan goes on, then you need to check your cooling system. Squeeze the hoses and make sure they do not have lumps in the liquid. Check also your anti-freeze. Does it have a normal color or does it look unusual? You may also try to flush your cooling system if you haven\'t tried it yet. It is recommended that you do this every two (2) to three (3) years.

    Check the radiator if it is clogged

    There may be lumps inside that is why it overheats even when at idle. If the radiator has internally clogged cooling tubes, the flow of coolant through the radiator is impeded and slowed down. At higher engine speeds, the coolant flows through the radiator faster, overcoming the clogs. Possibly your radiator is obstructed with dirt, bugs, and road grime. If the airflow through the radiator is obstructed, too little heat is dissipated, resulting in overheating. When the vehicle is at speed, a sufficient volume of air is forced through the radiator, but when the vehicle is not moving, the fan cannot draw enough air past the clogged radiator fins to carry away the heat from the coolant, resulting in overheating.
