1998 Chevy Silverado COOLANT LEAKAGE

The most common leak is the intake manifold gaskets leaking in the front or rear of the intake manifold, also water pumps are very common for leaking. Use a mirror to look at the weep hole under the water pump for leakage

Hi Chas,

When did you notice the lose of coolant and how much ruffly are you loosing?

How is the vehicle running?

Have you checked your oil to see if it over full, looks milky or frothy? I it has any of these it is most likely a blown head gasket or intake gasket. Also is there more steam or white smoke as some people call it, coming out the exhaust.

Post findings here in forum.
