You must loosen the motor mounts on the body of the car. I did not disconnect the motor mounts completely to get at the water pump bolts. One ALL motor mount bolts are removed I jack up the motor with a floor jack.

How to replace a water pump on a 2005 dodge grand caravan water pump is leaking, added fluid but is still leaking and now more frequently want to replace it as a do it ourselves


this isnt a solution,just a suggestion.my husband,a fairly skilled home mechanic,recently did this.it took 12 hours over a 2 day period.you have to remove everything from the front of the motor,including the motor mounts,to access the pump.make sure you change the timing belt at the same time if it shows ANY signs of wear so you aren't doing the procedure again anytime soon..good luck!!

1992 Buick LeSabre - Water Pump Bolts Near Engine Mount.


I'm not sure what motor you have in that Buick, but my wife's 92 Old's water pump went out and I had a heck of a time with the bottom two bolts. I talked to a mechanic and he told me to put a piece of wood on top of a floor jack, slide it under the oil pan and lift the motor off it's mounts to gain easier access ,and after I did, with a lot of patience I got the job done.(About 2 hours, a 1/4 turn a a time) I hope this helps

that is not an idler pully that is the power steering pully if you feel through the holes in the pully you will feel the 13 mm head bolts that hold the pump to the block remove those bolts the pump will drop down and you can then remove the water pump also you have to remove the studs using the inverted torx end on the stud to unscrew it then the mount will come out

Change water pump on 1995 toyota cor.le


alfred11s: No, you don't have to lift the motor. You do have to remove the right hand engine mounting insulator.
I will give you the procedure for the removal to access the pump:.
1.Drain engine coolant
2. remove right hand engine mounting insulator
3. Remove #2 and # 3 timing belt covers
4. Remove front engine mounting insulator as follows
a. remove hole cover
b. remove the 2 bolts from the mounting
c. remove the nut, the through-bolt and front engine mounting insulator
5. Remove the electric cooling fan
6.Disconnect engine wire remove the bolt and 2 nuts and disconnect the engine wire.
Water pump removal instructions:
1. Disconnect the crank sensor connector from the dipstick tube
2, Remove the dipstick tube and dipstick (only 1 bolt holds it)
3. Disconnect the water temp sensor from harness
4, Remove the two nuts and the # 2 water inlet from the hose.
5.Remove the three bolts which retain the water pump!
CAUTION! try to keep antifreeze off the timing belt. Put rags down and pack them where the coolant would normally spill.
WELL alfred11s: My answer should be a pleasant surprise.
Print it out and carry it out to the car.
If I've done well, maybe you can comment on what you think

How do I replace water pump[ on my 1993 buick park avenue.


Most often you do not need to totally remove the right motor mount. GM unfortunately made one bolt on the water pump that you can't get to w/o messin with the motor mount. There are actually two bolts that have access holes in the motor mount but in many cases you can get at and remove the one bolt with some clever maneuvering and the right tool. Yet that leaves the other ****** bolt. Now this is the PO factor....just one bolt you know some idiot designer left to make every bodies life difficult. So here is how you do it step by step. Loosen the bolts on the water pump flywheel then remove the belt. Take a oil-pan length 2x4 and use it in between jack and oil pan and jack up engine almost so that steering pump fluid cover on top side almost hits cross bar. Remove the center bolt of the motor mount holding the two halves of the mount together. Remove two bolts and one nut on the engine side mount. Remove 4 bolts (2 on top and two hidden on side) of the bolts holding the mount to the frame. Now take a big 2x4 and wedge it so as to move the engine to the driver side of the compartment. At the same time rotate and move the mount piece on the engine side--rotating about the stud [that the nut came off of]--so as to partly split apart the two mount halves. You'll see that you can now get at the two hidden bolts. Remove the water pump pulley wheel. There are a bunch of small and little bolts in the water pump...some on bottom side. Remove them and old pump. Scrape off old gasket. Apply new gasket and sealer to new pump and reverse order to install
