Changing a Water pump.

Have you done so much to the car today that it just doesn't fit into one section, or are you too damn lazy to split it all up? Either way, this is the section for you.

Changing a Water pump.

Post by Briano1234 »

Changing a water pump? Don't work at it from the bottom up....
Try this.

O dear, my water pump is nicht sie pumpin.
it is gerfunked beyond gerfunkin.
It is leaking faster than a Democrat creating new ways to tax me.

So I have joined the ranks after having changed out the pump only, Major pain in the ass as you have to remove timing covers and other crapola
It is Far easier and less the PITA to take it out as a whole assembly than to "follow" the just replace it as it is.


In my most humbled opinion.... you will have a easier day if you do the following.

NO YOU DON'T HAVE TO REMOVE THE TIMING BELT, BUT YOU DO HAVE TO REMOVE ONE 10MM TIMING COVER NUT, and the upper timing belt cover.

If you can visit a wrecking yard, get the bracket and barrel bolt adjuster off a 88 GOLF/Jetta as it makes adjusting the belts so much easier than the gear. You will need the Bracket, Barrel Bolt, and right side pivot bolt and nut, all are 13mm.


Disconnect the battery

Remove the 2 power steering res bracket bolts to allow you to move the thing out of your way while you are working.


Jack the car and or support it on ramps and or Jack Stands.

Remove the 5 13mm bolts that hold the power steering bracket to the block and to the pump, the major pivot, and the 2 that hold the p/s pump to the
bracket, and the 2 that hold the bracket to the block.

Image

Image

Image

Image

Remove the thermostat housing, and be prepared for the Deluge Use only a 6pt 10mm socket.

Image

Have a pan available to catch the fluid.

Image

Image

Now once it has mostly douched you, you will see the thermostat, pry that out with a flat blade screw driver
and get a second deluge.

Image

Remove the Alternator (see how to: http://www.mk1vw.info/modules.php?name= ... wtut&id=99)

Remove the upper radiator hose and the res hose. Bend them back and unwind them from your a/c hoses.

Remove the 2 13mm bolts and nuts that hold the a/c compressor and are the adjusters.

Remove the 2 8mm Allen bolts that hold the a/c compressor on the back.

Remove the a/c electrical connector.

Now Pry the a/c compressor out of the bracket.

Take the Belt off

Carefully move the a/c compressor out towards and rest it on the fan shroud.


Image

Remove the upper a/c bracket pivot bolt

Image

Remove the 2 13mm bolts holding the a/c bracket to the block (These are 2 of the pump housing bolts too.)

Image

Remove the bracket by pivoting it up, then using a pry bar pry it out.

Remove the 2 hoses that are on the back side of the water pump.

Remove the 10mm nut that holds the timing cover to the water pump.

Image

Remove the 2 remaining 13mm bolts that hold the water pump body to the block.

Wowsers it is out it is far by far the better method.

If you ordered a whole assembly, then clean off the mount area add a new o-ring and away
you go to replacing it.

before

Image

after

Image


Be Warned that you have to place the Alternator belt on before the a/c belt.

You need to only torque the w/p and thermostat cover bolts to about 17in/lbs so don't go honking.


Even if you didn't order the housing assembly, you can now get the pulley off and the 10mm bolts.

You can spray the back side of the bolts with pb-blaster....

I didn't need a housing as I had a spare one, and even after removing my old housing my cordless
impact didn't strip or break any of the 10mm bolts that hold the water pump to the housing.


Be sure to clean the housing and lightly sand it.

Image

Place the gasket on the housing, then the pump.

Clean all the bolt threads

Image

Hand thread all the bolts and coat the bolts with never-sieze

Image


For added measure, coat the back of the bolts with a anti corrosive paint:

Image

To move the Pulley over, I find that if I lock a Flat Blade Screwdriver between the bolt and pulley hub, I can use the floor
for leverage to loosen or tighten them at will.

Image

When putting the the pump back on use all 4 bolts, as you want to align it so that all 4 bolts start easily...


For those that wonder, I found a "metal Impeller" water pump locally at NAPA, sure I had to pay
20 dollars more for it but I am way happier to have the metal impeller......


Trust me when I tell you it is far easier to remove it this way than any other that you can think of.


Cheers

This is 100% correct. This is the only way I've ever known to deal with the pump and it's the only way I've ever done it. It can be a royal PITA, but in the end, it gives you far more room to deal with things. An if you're one of those that doesn't have AC, it's just that much easier.

Thanks again Brian for the pics and walkthrough. :thumbup:

We really need to get you a nice hi-rez camera Brian, lol. For all the technotes you put up, it's a shame Mr. Blury-cam is always helping you out.

Actually, it's just a shame we live so far apart. I'd gladly lend you a hand and take the pics for you. :thumbup:

Well it was a good camera when I got it, but then again it is about time I up-graded, but for being dropped, kicked, and wet when taking how-to's it is still kicking.... I should borrow my son's camera as it is a tad newer and 10MP.....gee I wish I didn't have any bills......well I never have any bills as the kids and wife rifle my wallet.... "Watch'cha got in your wallet?" "NOTHING" :lol:

Here is a picture of the OEM water pump, they can come in plastic or metal impellers.

Image


Here is the Saleri pump that I bought the other day:

Image


Since adding it to my car, I have seen a 40 percent decrees in running temp, I have also noticed that
the fan dosen't come on too much, and there is negligible temp climb on stop. Now I haven't had it out on a 100 degree day, but
what my old but noisy pump was doing the other day.... it is remarkable.

I only want metal impellers, but this Salari beat the other metal one I put in about 2 months ago.
This one is like Tiger Teeth compared to dentures. But then again metal beats plastic every day.

Some of the Vanagon guys swear the twisty-cone style impeller pumps better than the stamped-steel kind. I really have no idea.

Huge thanks for the writeup Briano! Will be using this for sure when I do my major overhaul on my 93...

Where did you get the Valero pump from?

Great write up, very well done
I have a very frustrating problem with a recently purchased 84 gti
The previous owner obviously was trying to delete the ac. I purchased the car in condition pictured.
I have went ahead and bought mk2 brackets and bolts to run alt set up w/out ac.
Only problem is I cannot find out how to remove the old ac / alt brackets? In the pic you can see the shelf / bracket that has a cut on it for whatever reason.
All diys and pics I can find do not have a set up suck as this so no info has been helpful.
If any one can please help me with the removal of this bracket it would be a huge help.
Thanks

That is the York "add-on" style. It was the "dealership" addition to a prebuilt car in the US.
I have seen them in the wrecking yard, but never worked on them.

I do have the parts breakdown for you.
