Keep blowing up radiators

[Hugo Habicht]

There is still a problem with your radiator cap. It should limit the pressure building up before damage is done to the radiator.

In your first post you wrote nothing points to the head gasket. Get a CO2 test kit, cheap, simple, fast.

I am also trying to track down the cause of high heat levels nearing the red zone.

Will attempt some of the tests/suggestions:

Belt tightening

Observation of fluid in radiator

Thermostat (it seems to be opening as both lower and upper hoses are hot)

New coolant as water has been added over time.

Is there an easy means to test for head gaskets failure or water pump failure?

Any suggestions?

It was a blown head gasket.

Curious to know the cost of that repair?
