Re: 94 tauras water pump
Hello, I presume you are fitting a New pump? if so all items should be in the box, some pumps use gaskets others use 'O' ring seals they are machined to a very good tolerance so mating surfaces seal well. There should be no need to use any sealant on the bolts/pump unless it specifies so on the replacement. If it were required then some would/should have been supplied with it. Hope this helps? Please press the Blue button if happy with my FREE efforts, Thank You! Paul 'W' U.K.

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.
if its leaking out of the vent tube hole,, you got a bad pump, if its leaking around the edges of the pump you didn't use sealer at the gasket and that will need to be addressed,, remove the pump and use gasket sealer then tighten down the gasket ( water pump bolts ) in succession , it keeps the gasket from getting a wave in it,
Is it dripping from the waterpump? Gradually getting worse?
It will appear to come from the back of the water pump. This means that you'll have to change out the pump itself.
Haven't actually done a sonoma..but basically the same on most vehicles. Pick up new pump from auto parts store. Some gasket sealer too is good idea. Also some anti freeze.
Drain antifreeze into bowl to reuse. Run it through a sock or other filter befor putting it back in.
Loosen and remove any belts. Remove the small bolts holding the pump to the block.
Possibly you may need to move stuff like the alternator to reach it??
Look at the new pump to see how many bolt holes, so you don't miss any.
Pull pump away. May need to tap the pump with hammer to bust it loose.
CLEAN the mounting surface. CLEAN the mounting surface. CLEAN the mounting surface.
Avoid gouging the surface. Apply film of gasket sealer to CLEAN surface, AND the gasket that came with the new pump. Block, Sealer, Gasket, Sealer, Pump. Position pump and bolt in place evenly. Snug up each side at same time step by step. Tighten firmly,but don't crank down too hard, you'll strip threads.
Restore any moved items, replace belts and tighten all up. Fill radiator. Start engine. Top up radiator. Top up again with gentle reving of engine. Close radiator. Fill top up bottle.
close hood if all seems ok.
NOT HARD BUT YOU HAVE TO DRAIN COOLANT OUT OF SYSTEM.CATCHING IT IN A DRAIN PAN .THE 2.4 ENGINE YOU HAVE TO REMOVE. OXYGEN SENSOR THE EXHAUST MANIFOLD HEAT SHIELD.REMOVE COOLANT INLET HOUSING BOLT THROUGH THE EXHAUST MANIFOLD .REMOVE EXHAUST MANIFOLD BRACE TO MANIFOLD BOLT.REMOVE TO EXHAUST TO PIPE STUDS.REMOVE COOLANT INLET HOUSING TO WATER PUMP COVER BOLT.REMOVE EXHAUST PIPE FROM THE EXHAUST MANIFOLD BY PULLING IT DOWNWARD.REMOVE COOLANT INLET PIPE FROM THE OIL PAN.REMOVE BRAKE VACUUM PIPE FROM THE CAMSHAFT HOUSING.REMOVE EXHAUST MANIFOLD FROM THE CYLINDER HEAD.REMOVE HEATER HOSE FROM THE HEATER OUTLET PIPE.REMOVE THE TIMING CHAIN COVER AND TENSIONER.REMOVE WATER PUMP COVER TO ENGINE BOLTS.REMOVE 3 WATER PUMP TO TIMING CHAIN HOUSING NUTS.REMOVE THE WATER PUMP AND COVER ASSEMBLY.THE 3.1 AND 3.4 ENGINES DRAIN COOLING SYSTEM .REMOVE DRIVE BELT.REMOVE WATERPUMP PULLEY TO REMOVE PULLEY YOU NEED A LONG SKINNEY SCREW DRIVER TO HOLD PULLEY FROM TURNING WHILE YOU REMOVE THE BOLTS.THEN REMOVE WATER PUMP.CLEAN OLD GASKET MATERIAL OFF ENGINE BLOCK WHERE WATER PUMP GOES.BECAREFUL NOT TO SCRATCH PUMP SURFACE ON ENGINE BLOCK.YOU CAN BUY CAN OF GASKET REMOVER AT ANY AUTO PARTS STORES. THEN WHEN YOU PUT ON NEW WATER PUMP.BESURE TO COAT BOTH SIDES OF THE WATER PUMP GASKET WITH GASKET SEALER .BEFORE PUTTING GASKET SEALER ON WATER PUMP GASKET.BESURE TO GET HOLES MATCH UP RIGHT ON WATER PUMP AND GASKET.WHEN YOU GET IN PUMP IN PLACE TORQUE IT AT 89 INCH POUNDS AND PULLEY BOLTS 18 FT LBS.THE 2.4 ENGINE BEST TO HAVE** HAYNES REPAIR MANUAL ** BECAUSE REMOVING THE WATER PUMP YOU ARE DEALING WITH THE TIMING CHAIN AND TENSIONER.YOU NEED ALL THE EXHAUST BOLTS TORQUE SPECS.AND WHEN YOU COMPLETE WATER PUMP FIX.ADD COOLANT.CRANK ENGINE.CHECK FOR LEAKS.BLEED COOLANT SYSTEM.
Hi This is d_hubbs: Removal and replacement of your water pump.I'm assuming you have a 2.5 Engine.You did'nt give your engine Information but about 75% of your Year and Model had the 2.5 in them.
1st start by disconnecting your negative cable on your Battery. Then Drain your Coolant into a Container: then remove your drive belts remove your fan from the water pump: You probally should also remove your alternator and A/C Compressor to make it easier to get to your water pump, now remove your lower Radiator Hose, then remove your water pump mounting bolts, now remove the water pump: Now Clean the water pump surface on your engine where your gasket will be. Besure its Clean Good : NOTE: Sometimes if you purchase a New water pump it will not have the drive belt pulley on it. if this is the case Remove your Pulley from your old Pump and install it on your New pump : now Run some gasket sealer on your new water pump where the gasket will go.put gasket on the new pump lining up your mounting bolt holes.also put a small bead of sealer on the engine where your water pump will mount: now Mount your New water pump to the engine with the Mounting Bolts.Torque the Mounting bolts at 25-30 Foot Lbs.
Inspect your Drive belts and Hoses its a good time to put new ones on if needed.Now put your lower Hose back on-re-install your A/C compressor and Alternator-Put your fan back on-now put All your Drive belts back on be sure to Adjust the Belt Tension and Lock down the Bolts.-Fill your Radiator back up with coolant,If the Fluid you took out is still fairly new ,you can use it. If its Aged best off putting new Coolant. Replace the Battey Cable Start your Car and Check for any Leaks , After your Thermastat opens you'll need to recheck your Coolant Level. if no Leaks and Cooling System is Full you Are Done. Please let me know how my advice and Solutions have Helped you. Thanks for Using FIXYA From d_hubbs
yes always use gasket sealer on both sides of the gasket. and make sure the old gasket is completely removed but do not use a chisel ar anything as you will leave gouges in the metal and cause a leak. Best to clean it is with some sand paper and just take your time. And just a thougtht but all i use is the black gasket sealer. It seems to wwork the best.
The use of silicon sealer on both the gaket and the threads of the bolts is important Not adding silicon sealer to bolt threads and shank sounds like the likliest cause of your fault unless it only appears to be coming from the bolt hole and in fact leaking from another source.
