I have a ford focus 2002, sohc 2.0 l engine.
When it the engine gets hot it the water
reservoir starts to bubble excessively, the
head gasket has been change, radiator
flushed, hoses, thermostat has been
removed to see if that was a problem but it
still persists any idea?
When coolant is at the proper temperature or even when it's overheated, it will not bubble unless there is pressure added to it. I'd recheck the intake manifold to see if it was installed correctly or it blow again.
Ok will re-check to my knowledge it was set properly but if that’s not the problem any other idea?
I meant to say, head gasket. Bubbling is due to pressure and it's coming from the engine. If not the head gasket, either installed incorrectly or blown again due to a warped head, it might be a crack in the head itself.
So i took my ford focus 2002 2.0 L sohc to another mechanic, and found out that the water pump was broken... that why the initial gasket was blown and why it was still overheating after the gasket was blown
