Examination
1. Check each part for cracks, damage and wear and replace the coolant pump if necessary.
2. Check the bearings for damage, increased noise and difficult rotation and replace the coolant pump if necessary.
3. Check for coolant leaks. Liquid leaking from hole A indicates a seal failure. Replace the coolant pump.
Installation
1. Clean the gasket-facing surfaces of the coolant pump and cylinder block.
2. Install the new pump gasket onto the coolant pump and tighten the bolts to the specified torque.
