Hi and welcome to Just Answer.
This water pump is under the covers on the front of the motor and is run by the timing belt, which must be removed to replace the waterpump... How comfortable are you in working into a timing belt, I can get you the steps and some diagrams if you think you would like to attempt the repair. If you are not comfortable working with the timing belt it would be time to talk to some friends about a reputable shop or technician on your area for this repair. Again if you are comfortable trying it just let me know and I will get you some data on this repair.
I look forward to your replies!
No problem, I will start getting some stuff together and repost in a little bit.
CAUTION: Keep the O-ring free of oil or grease.
TIMING BELT SERVICE
Mark belt running direction if belt is to be reused.
TIMING BELT TENSIONER
CAUTION: Index the tensioner in the vise the same way it is installed on the engine. This is to ensure proper pin orientation when tensioner is installed on the engine.
CAUTION: This procedure can only be used when the camshaft sprockets have not been loosened or removed from the camshafts.
