Antifreeze leakage in the engine cooling system usually occurs due to the fault of a failed water pump, or its component parts. In any case, dismantling the pump from the engine cannot be avoided. Otherwise, the water pump cannot be repaired.
It is necessary
- - 19 mm spanner,
- - 13 mm spanner,
- - a key in the form of a 10 mm hexagon.
Instructions
Step 1
Work on dismantling the water pump is carried out only on a cooled engine, otherwise burns to the body are not excluded. Thinking once again about safety will not hurt anyone.
Step 2
At the preparatory stage, the coolant is completely drained from the engine into a previously prepared container.
Step 3
Then the tightening of the fastening of the generator to the bracket is released, and it rises as high as possible.
Step 4
After that, the protective plastic casing of the timing belt drive is disconnected from the water pump.
Step 5
Further, by unscrewing the four bolts securing the water pump to the engine, the pump is dismantled, and then placed on a workbench for further disassembly.
Step 6
First of all, the drive pulley is removed from the pump, which is clamped horizontally in a vice, but in such a way as to exclude damage to the pulley itself.
Step 7
To do this, a belt is laid in the pulley, and wooden gaskets are installed on the jaws of the vise, after which the pump pulley is fixed in a vice with a certain degree of caution, and then three bolts of its fastening to the water pump flange are unscrewed with a hex wrench.
Step 8
After dismantling the pulley, the pump is further disassembled for refurbishment.
