The author of this document shall not be held responsible for any damages to you or your vehicle resulting from following any step discussed in the document. This manual is created only for a pictorial guide and should be used as such!
Introduction:So you're water pump went bad but it's not time for a timing belt change. You don't want to pay your mechanic big $money$ for a simple task but also don't want to spend a large amount of time messing with your car. I felt the same way and didn't need to change my timing belt.
Let me start by saying that Vasillov has written an excellent DIY on how to change the timing belt and Waterpump already. This DIY is simply an alternative with a major goal in mind.
Goal: Reduce time involved in changing water pump.
I have noted 3 items that increased labor time:
1: Front Passenger Tire removal
2: Motor Mount removal
3: Crank Pulley removal
I also noted some concerns involved with this shortened time.
1: The Crank Sprocket is covered but open at the top so you must be careful not to drop anything into the cover.
2: You must be extrememly careful to maintain timing belt tension on the Crank Sprocket in order to not 'slip' out of time.
*Lift the front of car with Hydraulic Jack and support the cars weight with jack stands.
*Place a container under the Driver Side of the radiator.
*Turn radiator coolant drain valve and begin releasing coolant. (The process will go quicker if you unscrew the lid to the coolant reservoir in the engine bay by the strut tower on the passenger side)
*Remove Coolant Reservoir. (1 plug, 2 hoses and 2 screws)

Turn Sideways, there's one hose underneath
*Unmount Power steering reservoir. (1 bolt) Do not remove it entirely, just unmount inorder to move it out of the way.
-Also move various hoses as you see fit (but do not disconnect or remove them just move them aside

Step 5*Remove Serpentine belt. Use an adjustable wrench and rotate serpentne tensioner clockwise. While you have the tension loose remover the belt.
*Remove Serpentine Tensioner (3 bolts in Green)
*Remove timing belt covers except the lower one (it involves way too much to remove and is not necessary for this job)
(Note: Mine were already removed prior to this job so I don't have the 'details' but a few bolts and they come right off)
*Mark timing belt with Nail polish to ensure timing lines back up after job is complete
*Let it dry (short time)
*Loosen timing belt tensioner. Do not remove the bolt, just loosen it.
*Slip timing belt off of Cam Gear slowly. Once it is about to come off keep slight tension in an upward direction. (This ensures that the timing belt does not slip off the Crank Sprocket)
*Zip tie timing belt to a stable solid point on front of engine bay. (Note: The timing belt will continue to have 'upward' tension by strategically making contact with the motor mount pillar and the alternator pulley)
-Remove 3 bolts carefully (do not drop in lower timing belt cover)
-Remove old water pump
Old pump... WOW!!!
-Install New water pump
-Install 3 bolts carefully (do not drop in lower timing belt cover)

*Slip timng belt back on Cam Gear
-Make sure to continue 'upward' tension
Pull upward till it is slipped on
-Match timing marks
*Create timing belt tension.
-Use L-shaped needle nose pliers to turn the 'Moon' bit.
-Place tips of pliers in the 2 holes on the 'Moon' rotate counter-clockwise.
-With tension engaged retighten the tensioner bolt.
*Install everything thing else you removed in reverse order.
* Refill coolant (Fill reservoir, start car, continue to fill as air bubbles float to top)
I just wanted to add something here at the end... If you have not replaced your timing belt, please rethink using my DIY and please go back and follow Vasillov's DIY about changing the timing belt and waterpump. It is vital to replace the timing belt to ensure the reliability of your car. A broken timing belt results in much more than simply replacing it with a new timing belt. A broken timing belt will bend your valves or worse. It can result in thousands of dollars worth of damage. Be responsible and make the right decision: Spend $40 for a new timing belt now or spend a couple thousand later because of a broken timing belt.?.?.? Your choice.
