Coolant leak on my 93 Silverado

[kasedian]

Well, I really did it this time. I was going down the street the other day, when all of a sudden, lost my PS, wasn't charging, and my temp started rising. I figured the serpentine belt broke. I was about 1 half mile from home, and figured I'd just ease it home. Well, it wasn't the belt, it was the idler pulley bracket that broke. I went to Autozone, which had one for 50 bucks, put it on, put the belt on, test drove it, and everything seems fine. Today, I get home from work, and there is a big puddle underneath. Coolant. I pop the hood, and see small coolant bubbles coming from between the intake manifold and the valve cover meet. I'm guessing it got a little too hot getting it home the other day. Anyways, I'm thinking about changing the gasket.Is there anything else I should do, or look at, while I have things torn apart? Or sould I just dump some "stop leak" in the radiator? Thanks.

That would probably be the intake manifold gasket failing. If it's leaking that bad, i doubt stop leak would permanently fix it.

The Bar's Leaks liquid copper ,not the pellets or powder ,is great for the time being.Unless you just wanna bite the bullet and get it over with.

The first thing I'd do is get ALLDATA so I could have instructions
and diagrams for changing out the intake manifold gasket.

You could try to retorque the manifold .
But good luck - it is a long shot.
Do a little homework, get your parts and tools together, and allow three times the time of what you think it will take to fix it.

Thanks guys. I found an awesome link showing how to do it. Very detailed. It's on a 97 Chevy - Close enough.

Use the Felpro gasket, in particular the most expensive one if they make several. When I did it on my 97 Silverado the gasket set ran around $50 from Amazon, which was the cheapest.
