How many bolt hold the cover secure,I need to check my water Pump.
And how hard is it to replace the water Pump itself

 

Remove that one big shoulder bolt in the middle of the cover, and it should wiggle right out. Some times it's a little tight around the bottom, but there's only that one fastener holding it in place.

Water pump replacement may as well include timing belt replacement, as you'll need to pull the belt to get the pump out anyways. It's a fairly involved job, probably 2-3 hours if you know what you're doing, and double that if it's your first time. There's plenty timing belt/water pump replacement tutorials on-line. Read through a few, and you'll get an idea of what you're up against.

 

What's going on? Is the pump leaking a little or a lot? If it's just leaking a little when cold, you may have time. There really is no other way to check the pump because the timing blet is wrapped around it. So, you can only check it for leaks.

Every so often they break, almost never. If it does break, you're done.

 

The leak was from the radiator itself,very small I will try Bar,s radiator sealant.
if that doesnt work i will try one of those Epoxy

 

Don't try anything except a radiator REPLACEMENT. It really is not worth the risk, that radiator springing a massive leak, blowing your motor and leaving you stranded somewhere you DON'T want to be.

Why did you ask about the water pump in the 1st place?

 

Radiator sealants are often a bad idea. First of all, they are a temporary repair at best. Second, they can often seal holes that are supposed to be there, like the radiator tubes themselves or internal air bleed holes within the cooling system. Bar's leaks tablets are usually okay on the second issue- GM actually installed them from the factory on certain troublesome cadillac engines years ago (!), but they're still a temporary repair at best.

Also, make sure all engine grounds are good and that the coolant is in good condition. A common cause of pinhole leaks in radiators is electrolytic corrosion. When there's a bad ground somewhere, or the coolant has become contaminated with something that makes it more effective as an electrical conductor, your cooling system can become an electrical ground, which causes some parts to literally dissolve from the inside out.

 

Do I need to put some type of sealer on the water pump? CHANGING TIMING BELT and pump today.

 

They say no but I put a little of the blue gasket sealer.
