Parked my 86 Fiero GT V6 in the driveway the other day, and then noticed that a large pool of coolant was forming under the rear passenger side. It looked as though a hose burst, but all the hoses were intact. Waited a while and started it again to see where it was coming out from. No leaks, until it warmed up. It seems that the 2 hoses on the passenger side of the engine are spurting out coolant from around the clamped ends connected to the water pump and engine, like there's too much pressure. But the temperature seems fine... and also noticed a pin hole leak had formed in the top hose.
Could this mean (on top of needing to replace the hoses) that the water pump has seized up, causing the coolant to pressurize in the hoses? I am hoping that the timing cover-to-head seal is fine, it could possibly be leaking from there too.
