Why Replace It
Banjo seals crush when the banjo bolt is tightened and are made to seal only once. A reused or worn seal can let coolant seep from the turbo coolant pipes, leaving crusty residue on the turbo or a slow coolant loss. Replace these seals any time the turbo coolant pipes are loosened or removed.
Installation Tips
- Clean the banjo fitting and the sealing face on the turbo before installing new seals.
- Make sure the old seal did not stick to the fitting or the turbo.
- Tighten the banjo bolt to factory torque specs. Do not overtighten.
- Top off the coolant and check for leaks after the engine reaches operating temperature.
