Removal and installation
Removal
1. Drain the engine coolant. See above.
Caution: Perform this operation when the engine is cold.
2. Remove the following components:
- drive belt; see chapter "Mechanical part of the engine";
- automatic drive belt tensioner; see chapter "Mechanical part of the engine";
- generator; see chapter "Electrical equipment".
3. Remove the water pump.
- Coolant will flow out of the cylinder block, so place a container underneath.
Attention:
- Do not allow water pump blades to come into contact with other components.
- The water pump cannot be disassembled and must be replaced as an assembly.
4. Remove the water pump housing as follows:
a. Remove the cover from the exhaust manifold. See chapter "Mechanical part of the engine".
b. Remove the oil dipstick and dipstick guide. See Chapter "Mechanical part of the engine".
Caution: To prevent foreign particles from entering the oil pan, plug the dipstick guide hole.

Installation
Installation is carried out in the reverse order of removal, taking into account the following:
See the original on the resource [nissanbook.ru]
- When inserting the end of the water pipe into the cylinder block, apply neutral detergent to the O-ring. Then insert it immediately.
Check after removal
- Perform a visual inspection to ensure that there is no significant contamination or rust on the water pump housing and blades.
- make sure that there is no play in the blade shaft and that it rotates freely by hand.
- Replace the water pump assembly if necessary.
Post-installation check
- Check for coolant leaks by applying pressure using an adapter (suitable special tool) and the pump (suitable special tool). See above.
- Start the engine and warm it up. Conduct a visual inspection to ensure there are no coolant leaks.
