The O-ring seal provides a tight seal between coolant or oil passages such as the oil cooler and coolant pipe connections. It prevents leakage of engine oil or coolant under high temperature and pressure. A worn or hardened O-ring may cause oil seepage, coolant leaks, overheating, or contamination between oil and coolant systems.

Suggest there something better to change other parts together if possible :
When replacing the O-ring seal, it is recommended to also inspect or replace:

• Oil cooler gasket set

• Coolant / antifreeze

• Engine oil and oil filter

• Connected hoses and clamps
  This helps prevent repeat leakage and ensures proper cooling and lubrication system performance.
