drain coolant until below water pump level. loosen water pump pulley bolts.then remove drive belt by rotating belt tensioner.remove drive belt from the right of idler pulley.carefully release the drive belt tensioner spring tension.then remove water pump pulley bolts and pulley.remove water pump bolts and water pump pay attention to the position old water pump when removing water pump so you can line up new water pump holes to the engine. be sure clean engine water pump mounting surface use gasket remover dont scratch engine surface when cleaning removing old gasket material. take new water pump gasket get it mounting holes line up with new water pump mounting holes.when done getting engine water pump surface clean.water pump gasket paper you need to put thin layer of sealer on both sides of water pump gasket use RTV SILICONE.LET SET UP 10 MINUTES. PUT GASKET ON WATER PUMP BUT FIRST MAKE SURE LINE UP GASKET HOLES WITH WATER PUMP HOLES BEFORE PUTTING ON THE GASKET SEALER.when gasket sealer set up 10 minutes then install new water pump with gasket to the engine torque to 89 inch lbs.or 10 NM that is about 7 ft lbs torque.you should be able turn water pump by hand if you cant turn water pump by hand got too tight damage water pump shaft bearing.when all done wait for THREE HOURS. before adding coolant i let RTV CURE SOME. torque water pump pulley bolts 18 ft lbs.
Park your car overnight and put a
large white piece of paper underneith your car. In the morning check
the paper. If the paper is wet with liquid, you could have a water pump
If the paper has green (in most
cases) fluid on it, there is a good chance your vehicle is leaking
coolant (sometimes refered to as "water"). In many cases, when you are
leaking coolant it could be coming from the water pump.
Turn the engine off and open the hood.
Locate the water pump pulley.
The pulley is the round part that the belt is attached to. To find it,
look for the belts. You will see more than one pulley. Your car will
have an alternator with a pulley and perhaps an air conditioner, power
steering and smog pump pulleys. If you are unsure, ask your mechanic to
point out the water pump pulley.
Grab opposite ends of the round
pulley and check for "play" (looseness): Try to rock it back and forth.
There should be no give. If there is, the bearings are going and it's
time to replace the water pump. By the time you can feel play in the
water pump pulley, you may also be able to hear the bad bearing when the
engine is running - there may be a low-pitched grinding noise coming
from the water pump pulley.
Visually check the water pump
(it's located behind the pulley) for signs of a coolant leak. If the
water pump gasket is leaking, it must be replaced. This is a good time
to get a new water pump, too, unless it was just recently replaced.
TO REPLACE WATER PUMP.FIRST YOU HAVE TO DRAIN THE COOLANT SYSTEM. REMOVE AIR INTAKE DUCT AND RESONATOR. REMOVE THE RADIATOR SHROUD AND FAN CLUTCH ASSEMBLY REMOVE THE DRIVE BELT. REMOVE WATER PUMP PULLEY.YOU NEED A PIN SPANNER WRENCH OR STRAP WRENCH TO HOLD WATER PUMP PULLEY WHILE LOOSEN WATER PUMP PULLEY BOLTS .YOU CAN BUY STRAP WRENCH OR RENT PIN SPANNER WRENCH AT AUTO ZONE PARTS STORES OR OTHER STORES HAS TOOLS CAN BE RENT. ONCE WATER PUMP PULLEY REMOVED. REMOVE THE WATER PUMP MOUNTING BOLTS. REMOVE WATER PUMP. IF WATER PUMP STUCK YOU CAN TAP WITH SOFT FACE HAMMER OR A LONG PIECE OF ROUND WOOD.WHEN WATER REMOVED.YOU NEED TO CLEAN THE SEALING SURFACE CAREFUL DONT SCRATCH SEALING SURFACE. YOU CAN BUY CAN OF SPRAY GASKET REMOVER.CLEAN SURFACE GOOD THEN WIPE WITH LACQUER THINNER OR ACETONE.THEN GET WATER PUMP NEW GASKET MATCH HOLES UP WITH GASKET TO WATER PUMP. ONCE HOLES MATCH UP APPLY RTV SEALANT ON BOTH SIDES WATER PUMP GASKET. THEN PUT GASKET ON WATER PUMP THEN INSTALL WATER PUMP TO VECHICLE.TORQUE WATER PUMP BOLTS TO 89 INCH LBS .TIGHTEN WATER PUMP PULLEY BOLTS TO 18 FT LBS THEN PUT EVERY THING BACK VISA VERSA.
Loosen alternator and alternator tensioner. Alternator tensioner bolts to water pump so that bolt will need to come out.
With the alternator loose, the main drive belt should be loose and be able to be removed, do this.
Loosen the tensioner bolt for the air conditioner, on the underside of the engine.
Losen the nut on the air conditioner tension wheel. The tensioner wheel
should now slide up and down freely, allowing removal of the air
Remove the 4 x 10mm bolts on the water pump pulley. Remove the water pump pulley.
Remove the 4 x 10mm bolts on the camshaft pulley. This is the
main pulley that all the belts connect to. There is a large 17mm bolt
in the middle of this pulley that does not need to be removed.
The camshaft pulley should slide off, however you will
probably have no clearance (because of the crankshaft bolt) to remove
the pulley. The pulley has to be removed.
Place a jack under the sump, use a piece of wood to protect
the sump. Jack the sump up 1/2 inch. Undo the two 14mm bolts in the
engine mounts. When the two left hand engine mount bolts are out, lower
the jack slowly until you can slide the camshaft pulley out.
Remove the plastic timing belt cover.
You should now see the timing belt, remove the timing belt tensioner pulley, being careful not to move the timing belt wheels.
Undo the bolts holding the water pump.
Water pump should come off, water will come out if you haven't drained it.
You should not have to remove any pulley besides the water pump pulley.This is the only pulley you need to remove.Take a good look and make sure you are not removing more than you need to.There should only be 8 bolts.There are no reverse thread bolts on this engine.Hope this helps.Good luck.
I've found the Haynes Repair Manual that you can get at Auto Zone to be the best one there is. They have step by step instructions with pictures on repairing or replacing just about anything on your auto. You can get them for around $20 - 25. Is yours a 3 or 4 cylinder? Auto Zone has a new service where you can actually look up repair instructions for your vehicle with pictures. Here's the instructions for a 3 cylinder for your year, make and model:
Disconnect the negative battery cable.
Drain the cooling system.
draining the coolant, keep in mind that cats and dogs are attracted by
the ethylene glycol antifreeze, and are quite likely to drink any that
is left in an uncovered container or in puddles on the ground. This
will prove fatal in sufficient quantity. Always drain the coolant into
a sealable container. Coolant should be reused unless it is
contaminated or several years old.
Remove the air cleaner assembly.
Loosen but do not remove the four coolant pump pulley bolts.
Raise and support the vehicle safely.
Remove the lower splash shield.
Remove the air conditioner compressor drive belt.
Remove the lower alternator cover plate bolts, loosen the alternator adjusting bolt and remove the drive belt.
Remove the crankshaft pulley.
Remove the coolant pump pulley.
Remove the timing belt.
Remove the oil level dipstick and guide tube.
Remove the alternator adjusting bracket from the water pump.
Remove the water pump rubber seals.
Remove the water pump mounting bolts and nuts. Remove the water pump from the vehicle.
First you must drain the coolant. Remove powersteering pump[keep hoses connected)this is just to make room for water pump removal so just sit it off to he side.Loosen the the water pump pulley mounting bolts, remove the drivebelt,remove the pump pulley. Remove the pump mounting bolts and pul the pump from engine.Install every thing in reverse ,but be sure to clean the mating surface of old sealer and gasket first, also be sure to use RTV gasket sealer on engine side of the new gasket.Be sure not to over/under tighten the bolts the torque specs. are 22 to 29 for the long bolts and 96 to132 for short bolts and 108 to 132 ft lb for the pulley bolts.
