For best results: on a clod engine, remove the radiator cap, with the engine off. Start engine and pour one bottle of MOTOR PURR METALLIC SEAL UP directly into the radiator.

Tip: If you start pouring the product 4 inches above the radiator, then raise the bottle 18-24 inches, the product will displace the coolant already in the radiator. No need to drain coolant!

Where there is no radiator cap on the radiator, remove one end of the upper radiator hose and pour directly into the hose.

DO NOT POUR PRODUCT INTO THE OVERFLOW TANK!

Allow the engine to idle above 1500 r.p.m. until the engine comes to normal operating temperature or drive the vehicle for 10 miles.

For head gasket, engine block & cylinder head leaks, idle the engine for 30 minutes, then drive for 10 miles.

Juan's Tip: To save driving time on a blown head gasket; add product to radiator, warn up engine to operating temperature, use radiator pressure tester to pressurize the radiator (up to maximum pounds stamped on the radiator cap.) The pressure will go down, so keep pressurizing the radiator until pressure doesn't leak down anymore.
