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.

I went all through this myself within the last year. You might find something of interest in my thread.

Where the heck is this coolant leaking from?

Ive had 2 v6 Fiero's so far, both dumped coolant like crazy from the water pump. The pump is cheap, and my best time so far is about 30 mins, just replace it! Remember to keep the bolts in order, and RTV the crap out of the new gasket..

Definitely going to replace it. Is there a way to tell for sure if the timing cover gasket is leaking? The way it's coming from there, it seems like the hose clamp is leaking but I can't see behind it.
