After an intake manifold change I have been experiencing what appears to be a bleeding problem.
The car will idle for an hour - the fans will cycle normally - everything seems fine. If I drive it slowly there won't be an issue, but if I get on it at all - as in a blast to 5K - coolant will blow out the overflow at the filler cap and pretty soon the temp guage will shoot up.
I refilled and bled it using a special tool that creates a vacuum in the cooling system. Then I started it up and noticed that with the radiator cap off the coolant will ebb and flow out the filler hole, dumping about 10 -12 ounces of coolant each time.
I am not running the heater - a decision I made to make bleeding the cooling system easier and because I don't need one where I live... Right.
The question is: Aside from the temp guage shooting up, what are some other symptoms of an air pocket?
Thanks.
