Q: Car overheating

asked by on

My car overheats. I think I might need a new head gasket.

Overheating is never good for any vehicle. It can be caused by many things like a bad thermostat, low coolant due to a leak, a clogged radiator, a bad water pump, etc. A blown head gasket is the byproduct of overheating, not the cause. Once it is determined that you in fact have a blown head gasket, the initial cause of the overheating must be repaired as well. A mechanic, such as one from YourMechanic, will usually use a chemical that test for combustion gases in the coolant to determine if you in fact have a blown head gasket. They will also be able to diagnose the root cause of your overheating issue.
