Overheating small block
I know this is a constant topic and have tried alot of the suggestions given here, changed thermostat, no thermostat, bled system, etc.
My problem is the car is fine for about 20 minutes or so and it runs at normal temperature. It has an electric fan which kicks in immediately on start up. After about 20 minutes of normal driving the temperature then starts to climb fast and throws fluid out the overflow. I turn off the car and if I try to loosen the cap slightly there is alot of "gurgling" in the tank. It is not consistent sometimes it will not overheat but after driving for awhile and I shut off the car the systems then does alot of "gurgling". The last time it overheated the top rad hose had collasped. It may well be an "air pocket" problem....
I am now considering an intake manifold mounted unit that Moroso markets with the filler/pressure cap right on the intake manifold.
It has predominantly British items on it such as a "Kenlowe" thermostat unit to kick in the fan.
Any suggestions?
