Chevrolet Astro Coolant Leak & Engine Overheating

A coolant leak may develop from the water pump. The engine may overheat as a result of the coolant loss. A leaking water pump should be replaced.

Coolant started leaking from the Weep-hole under the water pump shaft casting. I replaced the water pump and used a homemade gasket w shellac. No leaks woks fine -
