coolant leak
 

I have a 2002 blazer. I noticed it has been losing coolant lately. Now I see what appears to be dexcool leaking out the front intake gasket. It looks as though the gasket has squeezed out. Is this common. It is only weeping for now and dripping down to the water pump. How big of a job is it to replace this gasket. What is involved

It is not all that difficult and yes, it is common. The intake manifold gaskets were improperly designed (well material was improper). Felpro has an updated intake gasket with a metal frame. The part numbers have been listed in other threads as has a link to a very good D-tips.com article for replacing the gaskets.
