Instructions For Use
1) Install only in a cold engine. Shake bottle well. Remove radiator cap and pour the correct amount of product in per the dosage chart. Fill radiator and reservoir / overflow tank to proper level and reinstall radiator cap.
TIP: Radiator cap may be on top of radiator, on engine, mounted on a hose, or a screw cap on the pressurized reservoir overflow tank.
2) Turn heater on hot and fan on high. Run engine until thermostat opens or normal operating temperature is reached. Turn vehicle off and allow engine to cool. This may take up to 30 minutes or longer.
3) Top off radiator (add coolant as needed) and either run engine at high idle (approximately 1200 RPM’s for vehicles with a tachometer) or gently drive for 15 minutes. Turn vehicle off and allow engine to cool.
4) Top off radiator and leave Rislone HEAD Seal Blown Head Gasket Repair in system for continued protection. Drive vehicle as normal. Most leaks seal instantly, but some can take additional thermocycles which happen over a few days of usage.
