Installation & tips
- Confirm thread type and size on both sides, and use the right sealant or none as the fitting type requires.
- Hose: Match hose size to the fitting.
- Put the new part next to the old one and compare the shape, mounting points and connections before you install it.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
