Coolant system O-rings are exposed to constant heat and chemical exposure, causing them to harden, crack, or lose elasticity over time. A failing seal can lead to coolant leaks, overheating, and potential engine damage. Replacing O-rings during servicing ensures proper sealing, prevents leaks, and maintains reliable cooling system operation.

When to replace
•  During coolant pipe or housing removal
•  Visible coolant leaks or residue
•  O-ring appears flattened, brittle, or cracked
•  Preventative replacement during cooling system service
•  After engine overheating incidents
