If it is an internal leak the coolant will end up in the crank case mixed with your oil and it will ruin the bearing/engine - if external leak then the engine will overheat when it runs low on coolant, and blow your head gasket
Remove the manifold and change the gasket. And voila!!!

How do I change the head gaskets on my 1998 ford explorer?
You will need to remove the exhaust manifold retaining bolts in your 1993 Chevy Astro. Remove the exhaust manifold. Remove the exhaust manifold gasket and clean the surface. Reverse the process to install the new exhaust manifold gasket.
if it is just a blown exhaust manifold gasket it can ruin your valves, so replace it correctly and make sure everything is clean before putting on the new gasket

Irratic idling condition is indication of intake/inlet manifold gasket leak. Change gasket immediately. This particularly applies to EFI engines. Newaz.
you will have to unbolt the exhaust pipe from the manifold pipe and then you unbolt the manifold pipe from the engine, remove old gasket and make sure both sides are clean of the old gasket and then install new gasket and bolt manifold back onto engine.
What engine? and ensure it is a bad gasket, not an intake plentum.
