How do I purge a vapor lock in a 97 Buick Riviera supercharged vehicle
i replaced the water pump and serpentine belts on the car, but water is not getting to the engine. I am sure it is a vapor lock, but do not know how to purge it.
Vapor lock is when the gasoline coming to the engine gets so hot it boils away before it reaches the engine. What you have sounds like air in the cooling system. There's a special tool for this that can be bought at your local auto parts store. HTH. -Jim
Take off the plastic cover over the engine. Follow the upper radiator hose to the engine (Coolant outlet). There is a bleed screw on the outlet. Open the bleed screw, and fill the radiator. You can also crack it open a little, with the engine running, to purge the air out. Follow the link for a picture. http://contentinfo.autozone.com/znetcs/product-info/en/US/cwa/815167/image/3/
Thank you, got the car fixed finally.!!!
