overheating

Hi there. Check the condition of the coolant and see if its full and new. I recommend putting a new radiator cap on and putting in a new thermostat. Once a thermostat is introduced to the atmosphere after being submerged...

This could be serious. Driving a car while it is overheating can do a lot of damage to the engine. The cylinder walls need to be bathed in coolant at all times or the surfaces become so hot that the...

Hi there. Your vehicle running hot only when driving could be the thermostat (https://www.yourmechanic.com/services/thermostat-replacement) only partially opening. It may be the result of air trapped in the cooling system when the radiator was replaced. The cooling system may need to...

Hi there, thanks for writing in. I'd be happy to help. The cooling fan in your car is electric. It is triggered by a relay and temperature sensor. If equipped with air conditioning, turn it on and see if the...

The white smoke is a sign that coolant or water is leaking into the cylinders. The radiator and overflow container are examined and checked for the right amount of fluids. The engine oil is checked next to make sure it...

It sounds like the engine has overheated severely. The leaking fluid was most likely coolant from a broken hose or water pump for the cooling system. The cooling system and engine will need to be tested now that the engine...

I wouldn’t condemn the head gaskets just yet. Intake manifold gaskets are a common failure item on your Chevy's engine. When they fail, they can leak externally, or internally, or both. When they leak internally, coolant gets into the oil....

Check to see if the cooling fan clutch (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-fan-clutch) is fully engaging when the engine is heating up. You can test this by putting a tissue in front of the radiator or condenser to see if the fan flow is...

Hi. The transmission temperature message pops up on your control panel when the powertrain control module (PCM) has detected excessive transmission fluid temperature. This is a warning to the driver as extreme temperatures can damage the transmission. Transmission temperatures can...

The cooling system would need to be completely checked out to see if the cooling fan circuit is working correct. If the fans are not coming on it would allow the engine to overheat. The thermostat would cause the engine...

You need to check to make sure the cooling fan is coming on. If it is not then further diagnosis will need to be done by scanning the computer to see if fan control is turning on to see if...

A number of faults can occur when an engine overheats. If the engine was overheated severely, it is possible that the engine has internal damage and has seized. Also, engine electronics are very sensitive to heat and liquids. If coolant...

Hi there, thank you for asking about your 2000 Dodge Grand Caravan. In most cases, the symptoms you're describing are related to a problem with your radiator thermostat (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-thermostat). The thermostat is supposed to open the radiator to flow coolant...

Your car is only three years old and so should not need transmission fluid. If the level was low, you should check to be sure there is not a leak. It's very easy to overfill the transmission so it would...

Hello. If the vehicle overheated to the point where steam started to escape, you are better off replacing the engine altogether. Once the cooling system is filled with water, it can be pressure tested to see if there are still...

Hello, thank you for writing in. You are correct in assuming the water pump may be to blame. You may also want to make sure the fans are turning on, and that your radiator and overflow tank both have the...

Hi there. This is a common problem. It is likely that a cooling system thermostat got stuck closed causing low flow through the cooling system and requires that it get replaced. It is also possible that there is a radiator...

If your coolant is low, you may have a leak that needs repaired. If your coolant level is normal, the problem may be with your thermostat (this part regulates engine temp), the cooling fan, or radiator. You need to have...

Hello. If a thermostat is completely stuck closed, then it does need to be replaced without driving the vehicle. If it is not opening then it will be very easy to overheat the engine. If you need to have this...

I would suggest checking to make sure the coolant temp sensor (https://www.yourmechanic.com/services/coolant-temperature-switch-sensor-replacement) is working correctly. This tells the coolant fans when to come on. I would also check to see if there is any white smoke (https://www.yourmechanic.com/services/smoke-from-engine-or-exhaust-inspection) coming from under...
