🔌 Function

Seals the heat-exchanger package so fan airflow is forced through the radiator and charge-air-cooler cores.

⚠️ Common Signs of Failure

• Cooling-air bypass
• Higher coolant or intake-air temperature
• Seal torn, hardened or missing
• Core movement or rubbing
• Dust tracks around the unsealed frame

🛠️ Service Notes

• Clean the housing bore and the shaft, and check the shaft for a wear groove where the old seal ran — a new seal on a grooved shaft will leak again
• Fit the seal with the lip and its garter spring facing the fluid being retained, normally inward towards the oil, and to the depth specified for that housing
• Press the seal in square using a driver or plate that bears on the seal's outer face and never on the lip; a cocked or dished seal will leak from new
• Lightly oil or grease the lip and the shaft before assembly unless the manual specifically calls for a dry fit, and protect the lip with tape or oiled paper when passing it over splines, keyways or threads
• Check the garter spring is still seated in its groove after fitting, then turn the assembly by hand before running it up
