What is the cause of an overheating engine?

Answer 1

Answer: car overheatingIt could be a number of things - radiator problems, leaking coolant tank, blown headgasket. The most likely however is that you have a leak/hole somewhere in the heating/ac system. You should get this checked out ASAP to prevent damage to the headgaskets. I had to have a hose replaced for the same problem and it cost around $100. However, if you let it go it could be quite costly.

Preventative help: Make sure you keep a gallon of water and a gallon of coolant (premixed or the kind you mix 1 part water with 1 part coolant) - this way if it begins to overheat, you have some options you can do yourself.

AnswerCan be a few things. Most common is a bad thermostat. Could be low on coolant from? Check all hoses. Bad/plugged radiator?

if there are no leaks or explainable reason for the overheating you probably have a air pocket in the cooling system. The trick to bleeding the cooling system of a air pocket is to elevate the front of the car using jack stands or park on a slight incline let the car run with the radiator cap open and coolant to the top of radiator. as the air bleeds to the top you will be able to add about a half gallon of coolant the fan will kick on and you will notice the fluid swirling at the top of radiator. when this happens you have successfully bleed the air from the system. Replace the cap and ride.
