hi guys,
I've got a bit of a puzzling problem i was hoping you could help me solve. I own a 1995 bronco with a 5.0. I just recently completed my motor swap into a fresh 5.0. along with a new water pump and radiator. The donor motor is a 5.0. H.0. out of a 1988 Lincoln. My question is why is my cooling system pushing coolant over the top of the overflow tank? The coolant in the tank is ice cold and the upper radiator hose is luke warm and the lower is cooler than that. The thermostat is new too. Also when i'm idling or step on the gas I get a gurgling noise coming from the passenger compartment. I think it is the heater core. A theory I had was that there is air trapped in the system that needs to be bled out. Would a coolant system flush help. I'm sure that would clean out the red residue in my overflow tank. Any help would be greatly appreciated guys. Ths truck is my daily driver. I know about the reverse flow water pump issue and my truck has the correct flow for my stock system.
