How do you replace the water pump on a 1998 Chevy Malibu?

If its a 6 cylinder, the water pump is very easy its closest to the front passanger side. Remove the pulley and theres a few 10mm bolts remove them ,remove the water pump and clean the area and reinstall the new pump. Its a 20 minute job remember to drain your antifreeze other wise it gets a little messy!

One should remove the belt first by releasing the tension from the tensioner pully The trick is to remove the four bolts holding the pulley in place. There is a special tool. However, you can hold one bolt while lossing another.

Then use two of the loose bolts as leverage for the last bolt.

Awnser well according to my understanding anyone with hands and a brain could easily do this task. All it takes is some ballz and some god damm comon sense...... lmao follow me at twitter. Com/jackyobody123 Answer It depands on what engine you have but none are REAL hard.

You will need guidance though and the best way is to get a manual on your vehicle and you will have it for this repair and also for the next one Answer If your 1998 is the same as my 1997 with a 5.7, you will also need a special wrench to remove the fan clutch. It is retained with a large, left hand thread nut, instead of the 4 small bolts of past models Answer Are you sure its a left hand thread? They are standard threads.

Righty Tighty - Lefty Lousy. You don't need any special tools/wrencherszperiodz You loosen up two of the ten millimeter bolts holding the fan on, but not all the way. Lodge the wrench in there to hold the water pump from turning.

Put a large adjustable wrench on the big nut for the fan clutch and smack it with a ball pein hammer. The threads should not be super tight on the fan clutch. This can be done by one person.

I've done it many times by myself.

On a v 6 motor the water pump is located just above the air comperssor with a diagram of the belt route take the 4 outside pulley bolts loose first then take off serpentine belt it makes it easier to hold the pulley then 5 bolts holding the water pump Answer 1. Take timing cover off. 2.

Take motor mount off. 3. Take harmonic balancer off.4.

Take water pump hosing off.(7 bolts) 5. Take timing chain techner off.6. Take three nuts off water pump, pull water pump out and replace sounds like the above answer was confused with a chrystler product...you shouldn't listen to people like this.........they do not know about the simplicity of gm products...and who puts 7 bolts on a coolant hose..PLEASE!

There are only a few bolts, no need to undo hoses, just pop belt off (let dangle) and unbolt the water pump,after draining coolant to a suitable level, replace pump and gasket (with sealant) and reverse dissassembly (new pump does not come with pulley, so be shure to swap it out to the new pump) Actually, sounds like the above answer was confused with a 1999 Malibu w/ the 2.4, where the water pump is a (roughly) 7 hour job I just changed one of these pumps on a 3.1 v6 last week. It's realy quite simple. After you loosen the belt and remove the water pump pulley ( it's the top front pulley ) You will see the water pump mounting screws behind the pulley, remove these 5 screws and the pump comes right off.

One important thing to know is to remove small brass bleed screw where top radiator hose hooks to motor while your refilling system with coolant, then put the bleed screw back in after coolant squirts out the bleed hole.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
