Benefits & Tips
Quick bolt-on replacement keeps downtime minimal. Simply unscrew the original mounting bolts, position the new blanking plate alongside the gasket, and tighten securely. Keep in mind that minor surface marks on the gasket contact area are standard manufacturing tolerances and will not compromise the seal. If you prefer hands-free work, we recommend having a licensed technician complete the swap.
- Clean mating surfaces thoroughly before fitting to ensure maximum sealing effectiveness.
- Follow proper torque sequences to avoid distorting the aluminum housing during reassembly.
- Verify coolant lines remain intact and leak-free immediately after finishing the repair.
