5.0 (306) Heating Issue
I have a 90 GT Mustang with a fresh 306 and mods: E-303 cam, Cobra Upper and Lower, aftermarket headers, etc..
The car will not stop overheating!
Blew a head gasket-- fixed-- still overheats.
It naturally has all new hoses.
New aluminum radiator-- Not one of el cheapo models, either.
Naturally, a new water pump.
All components of the cooling system are new.
To give you an idea:
I was going to change the thermostat, again.
I backed the car out from the car-port, turned it around, backed up into the car port, turned it off. Lifted the hood, disconnected the top hose clamp, and it almost blew the hose off, there was so much pressure already built up!
I removed the radiator to see if there was possibly some obstruction. Flows freely.
Here are a couple of things I have pondered:
Obstruction in the block?
Intake manifold gaskets installed wrong? Actually, this was supposed to have been double checked when the original head gasket blew.
Although new, and supposedly for a Fox, could the cross flow radiator be flowing the "wrong way"?
Water pump circulating the wrong direction?
The question is, how do I check the above, especially the later two.
This thing is about to frustrate me....big time!
All help appreciated!
