Ok i have a coolant leak that is on top of the timing cover behind the alternator . There is a small hose that that connects on a metal fitting that has corroded really bad. Dose anyone have a pic or can someone explain where that fitting goes and can it be easily replaced ?
THanks

I believe (not sure on your year) that it'* the coolant bypass fitting. From the factory on the 92-95'* they were plastic and you could replace them with metal. Like I said though..I'm merely buying time for the guys that know to wake up and post for you.

it seems to been a fitting on the water pump casing next to the elbow. And the hose is an * shape that connects to a nipple that is seated right there behind the alternator (1990
bonneville) between the heads. the hose is 3/8 rubber.
Can this be block off if not looks im going to have to try and tap it for a new fitting or i guess get a new front casing :(

Bill

Determine if the leak is coming from the hose or the fitting. The hose is cake. The fitting you could remove and apply high temp sealant to the threads.

that dose this line cool can someone post a pic. Or explain i want to know if i can get away with blocking it off

Its not wise to block off a bypass hose to the pump.
