Removal and installation
Removal
1. Drain the engine coolant. See above.
Attention. 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.
Attention:
- Do not allow the 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 dipstick and dipstick guide. See chapter «Mechanical part of the engine».
Attention. To prevent foreign particles from entering the oil pan, plug the hole under the oil dipstick guide.
With. Unscrew the water tube mounting bolts.
d. Remove the water pump housing.
5. Remove the exhaust manifold and three-way catalytic converter assembly. See chapter «Mechanical part of the engine».
6. Remove the water pipe.
Installation
Installation is carried out in the reverse order of removal, taking into account the following:
- While inserting the end of the water tube 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 the water pump body and blades are free of significant contamination or rust.
- Make sure there is no play on the blade shaft and that it rotates freely by hand.
- If necessary, replace the water pump assembly.
Check after installation
- Check for coolant leaks by applying pressure using an adapter (suitable special tools) and pump (suitable special tools). See above.
- Start the engine and warm it up. Carry out a visual inspection to ensure there are no coolant leaks.
