water pump replacement
I am mobile again.
Ok so I changed my water pump this after noon. I started at 4 pm and the old pump was off the engine by 4:05 pm. (My drive belt had been torn to shreds by the water pump pulley. All I had left were little bits of rubber and a really long thin wire.)
1. Water Pulley bolt
2. Water Pulley
3. Water pump
4. O-ring, included with pump
The pump is held on by 4 nuts (red arrows). Simply remove them and then get 2 M6 screws and put them in the threaded holes and tighten them in. (white arrows). You can skip this and simply pullout the pump, but since I had my fan off I didn't want the pump to go flying into my radiator os I opted for caution.
Lube the o-ring on the new pump with some coolant to help with installation. Mount the pump on to the 4 threaded studs and then tighten the nuts.
Pump was installation was done by 4:15 pm.
Next step was to put my drive and ac belts back on. ac belt = no brainer. drive belt = headache.
The Bentley manual is wrong, as previously mentioned before by others.
The tensioner bolt is under the cap on the ilder pointed here,
30 mintues later, the job was done.
I hope this helps. Let me know if there are any questions. I apolpgize for the crappy posting, I don't know how to get pictures to show up.
