Q: is it a temp sensor or bad head gasket?

asked by on January 18, 2017

So today we drove my 93 escort for the first time since it had a heating core and brake replacement. Out of no where it started trying to overheat, we tried to add coolant and it spilled straight through underneath the radiator. It started to sound like it was bubbling, so we have no clue what to think at this point. So we asked a friend and he said he thinks it sounds like a temperature sensor, but then another says head gasket. So i need better advice please!

My car has 72000 miles.
My car has an automatic transmission.

A diagnostic would determine the root cause of the overheating. If the coolant level was low, and/or there was trapped air in the cooling passageways, perhaps related to the heater core repair, those faults themselves can cause overheating. If the coolant level was low due to a leak, such can be found in a leak diagnostic with simple pressure testing. There are a few other common causes of overheating, namely a faulty thermostat, a plugged radiator, collapsed hoses, and a faulty water pump or drive belt. Certain engine faults, such as a leaking head gasket or poor engine running condition can also cause overheating.
