Mr. Gasket 2470S Domestic ThermoCap 13 PSI-SLVR
- Combines a pressurized radiator cap with a thermometer element that eliminates potentially dangerous guesswork.
- Lets you know exactly when your coolant temperature is low enough to safely open your radiator cap.
- To install just take off your old cap and screw on the new one.
- If the temperature gauge indicates that the coolant is too hot just rinse the radiator with cool water until the temperature drops into a safe zone.
- Also available in blue (part number 2470B) and red (part number 2470R).
