Water pump removal

I have a 2022 Safari/ V6, 2WD.

I have most of the front engine comonets out as I have to change the power stearing pump. As I am this far into it I would like to chang the water pump as a preventative repair. The limited service manual I have, says to remove the cooling fan clutch first. It states that the large bolt type fitting on the back side of the clutch is either a left or right hand thread. The problem is that in either direction all I get is the pump pully sliping on the belt. Is there a better way?

Yours: Tony

Its easier to remove with the belts on..but to late for that....you will need to heat up the part that screws onto the pump then take a big screwdriver or small crowbar and wedge it behind the pulley...... the fan will turn off to the right ...reverse threads.....hopes this helps

Put a prybar between 2 of the small fan bolts. Have someone hold the prybar, or rest it on the frame if it is long enough.Then turn the big nut on the fan to the left.It will be VERY tight. If that doesn't work, you can probably rent the fan removal tools from your local parts store.

Want to change Power Stearing Column

It is fairly straight forward except for the electrical that goes through the Column itself.

Be careful, I am assuming you want to change with a TILT?

Why do you want to change it ?

My car is making whinning high pitch sounds when im driving then it will stop and eventually come back, is it the power stearing pump or the power stearing hose leaking

You most likely have a leak. You shouldn't ever have to add power steering fluid. It is best to get it checked out and repaired while the leak is small. If you wait, the leak will get worse and the oil gets dumped on hoses, belts, wiring harnesses, computer sensors, etc. and can cause severe damage to all of these items, as well as rubber engine mounts and suspension parts. To properly maintain your vehicle, NO fluid leak should EVER be "tolerated". Fluid leaks (of all types) are the leading cause of sending cars to the scrap yard way before their time.

How do i replace water pump on 93 gmc safari

Locate the cooling fan in front of the radiator...when you remove the serpentine belt and fan assembly (including the pulley)..usually 4 bolts on the front of the fan...you can see the water pump...Sometimes you can ask your Parts store to show you the new part...(water-pump) this can help identify what needs to be removed in order to replace...Use gasket sealant on the new assembly, and I also recommend the anti-freeze that is labeled "For All Models"...for longevity and cooling...You do not have to remove the radiator or anything else...Hope this helps...:)

2001 dodge 2500 diesel oil leak in front of power

The power steering pump is piggie backed to the vacuum pump. The seal in the back of the vacuum pump has engin oil under presure behind it cousing a leak that gets worse over time. Cummins make a seal kit to fix this leak.

Power steering light comes on and then I loose power steering

Gonna take a gander at a guess, and say a power stearing pump. Are you losing power brakes at the same time? If so, probably a serpentine belt. Or a loose pulley (bearing) in there. If only power stearing, check the power stearing fluid first.

86733GH3 REPAR TIMING BELT

3.0l Mitsubishi 6 cylinder.
support engine... remove engine mount... remove alternator, power stearing pump, compressor (if equipt) do not remove hoses from power stearing pump or compressor move them out of the way were they wont get damaged. Remove the tension pulley for the serpentine belt, and the tensioner for the compressor belt if equipt. then remove the compressor mounting bracket. Next remove the engine mounting plate and the crank pulley and balancer assembly. you should now be able to remove the the 3 piece timing cover. Once removed remove the tensioner spring from the water pump and loosen the tensioner nut. Remove the belt. At this point it is also recommended to replace the water pump and plumbing as well. The water pump service life is aproximately the same as the timing belt at 60,000 miles. This engine in stock form is a non interfering type engine. Meaning that moving the cams or crank out of sync will not cause damage. Turn each of the cams over by hand and line them up with the timing mark on the top of the back cover with the marks on the pulleys. Using a wrench turn the crank so that the pulley mark lines up with the mark cast into the block. replace the belt, tensioner spring (replace tensioner if warn) and tighten the tensioner bolt. roll the crank over 2 complete turns forward and recheck the cams to make sure the marks are still lined up. roll the crank backwards and recheck the timing marks again. (this process is much easier done with the plugs removed.) If everything is still lined up correctly (crank at TDC and cam pulleys pointing to each designated mark on the covers.) reassemble the cover and assessorys in the reverse order that they were removed and reinstall the old motor mount or replace if needed.
