Nissan Repair: replacing water pump on 2000 Maxima SE, haynes manual, inner fender

Question
Regarding the question below, I have a 2000 Maxima SE on which I just had the starter replaced at the dealer ($300 + labor) and was notified that my water pump was seeping and my overflow jug was empty (also mentioned that tensioner chain would have to be adjusted). Estimate, parts & labor, was over $700. Is that still something best for the dealer to do? Thanks.

I need to replace my water pump. Where is the best place to go and get installation instructions? It can't be that hard to do and I hate paying a garage labor rates...


Answer
Gary,

This is major surgery since the waterpump is in the engine and a pain to get to.  Also, you have to unload the chain to get the pump free and did I mention that you have to get to it via the wheel well, with the tire and inner fender cover removed.  I hate to pay shop rates but this one warrants it unless you are really into engine work.  A Haynes Manual shows you how to do it and has instructions.  If you want to do it get the pump from Nissan so you will get another 12 years out of it.  Don't get me wrong since you can do it but following the procedures, step by step, is vital to making sure the engine does not jump timing while you change the pump.  Also, change the oil and antifreeze.  Lastly, use a good sensor safe silicone to seal the water pump access point as well as the tensioner access point.  Both plates need to be cleaned and dry before you install them with the new sealer.

Jen,

This is cheap due to the labor involved and it is best left to the dealer.  If the timing chain slips it will bend the valves.  I would not touch it.  Leave this to the dealer and be sure to get all paperwork on the job.  Also, make sure they change the oil and filter and antifreeze when they do the job.  When they open the access covers and remove the pump antifreeze is going to get into the oil, if it hasn't already.  So, it is worth the extra cash to be done with it.
