Installation Highlights

1. Remove the Old Pump: Drain coolant, disconnect hoses, and unscrew the mounting bolts. Carefully detach the old impeller if necessary.
2. Prepare the New Unit: Apply a thin layer of anti‑seize compound to the shaft threads and ensure the gasket is correctly positioned.
3. Mount the Pump: Align the flange with the engine block, tighten bolts in a cross pattern to avoid warping. Reconnect hoses and refill coolant.
4. Test Run: Start the engine, check for leaks, and monitor temperature gauge to confirm proper operation.
