'86 720 Coolant Petcock Location?

[proxin76]

My water pump just shat out on me, and I need to drain the coolant before I can pull

the radiator to get to it. I spent about 30 minutes taking stuff off the bottom of my front

end today trying to find some kind of petcock valve to drain the coolant, but I can't

figure it out. Where should I be looking, or do I just need to disconnect the lower coolant

hose and let it dump like that? It's a carbureted z24, btw. Thanks in advance, everyone.

I believe it's on the bottom tank, driver's side, facing the rear.

Drop a hose. Much faster. Fuck it.

^ agree

I do not mess with the pet cocks unless I am redoing the radiator.  I have had the break and then your screwed.

[flatcat19]

^ That.

The proper way to remove a rad hose is cut them off. I've fucked more than one outlet on a rad trying to get a stuck hose off. Never broken my pet cock before and that's what it's for. Just don't over tighten them and remove or loosen them when warm.

I have broken the plastic petcock on my 521 before.

I have never messed up a radiator outlet, but that doesn't mean it will not happen, but even though you cut the hose off, you still have to get it off the outlet, so unless I cannot get the hose off the lower outlet, I will not cut it off, well I might at a wrecking yard. :lol:

Try living in the desert I guarantee you will break petcocks.
