Q: Car keeps running hot

asked by on November 10, 2016

I'm very puzzled on what could be wrong with my car. I keep hearing different things radiator, thermostat, or blown head gasket. It ran hot twice within 1 week. Whenever it first ran hot my "add engine oil" light came on. Then it start smoking and the water in my jug gets to bubbling. I took it to a mechanic he said blown head gasket. I googled each problem and they all described what I mentioned above. I want your opinion on what could be wrong with my car.

My car has 140456 miles.
My car has an automatic transmission.

Overheating of any kind will cause the cooling system to boil, creating the bubbling in the coolant jug. All of the parts you listed can make this happen if they are not working correctly. The question is which one is the problem. I would trust a mechanic over all other sources of information because I would assume he or she took time to diagnose your car. Diagnosing is the act of testing your car to figure out what is wrong with it. If you don’t trust the mechanic you have already taken your car to, I recommend having an overheating inspection done from YourMechanic to give you another opinion.

There is nothing wrong with getting more than one opinion. Personally I trust those that can demonstrate to me why they believe a particular failure exists. If a mechanic is prepared to explain there diagnosis in a fashion that makes it understandable to you, you should trust him or her.

As for the add engine oil light, it is common for more than one light to come on to get your attention. Simply check the oil level and add oil if necessary.

Good luck!

My car is running hot...it was smoking from under the hood, after a little bit of cooling, the smoke stopped, but it still smells

I believe you have a bad thermostat. Symptoms of a bad thermostat are coolant boiling over and very tight upper radiator hose. The smell is going to be because of the antifreeze on the engine. No worries that will go...

What if I already have all the new parts just need someone to install how much will that

Hello, my car's temperature isn't rising, so the ac isn't working, what do you think is the problem? Compressor, or Radiator?

The radiator is part of the engine cooling system and would not typically be inspected or serviced if the passenger compartment air conditioning system is not working. If the car engine is overheating you might inspect the radiator though. If...
