DIY: water pump and belt tensioner on M3 VR6

Post by Jetta2 » Sat May 26, 2012 6:17 pm

Mods/Admins, please move to FAQ section as I cannot make a new topic there.


So, DIY guide to replace the water pump on a Mk3 VR -

I did do some reading on Vortex as there are a few DIY guides there, but here is mine.


New belt tensioner and water pump from GW along with some fresh coolant:
Image

Motor as it was:
Image

Airbox and intake pipe removed:
Image

The belt tensioner:
Image

Bolt inserted and tightened up to relieve tension on the belt:
Image

3 bolts that must get removed to take the tensioner off:
Image

And off:
Image

Old and new:
Image

Now to get to the water pump:
Image

No way in hell you will get that pump out with it sitting so low, so a simple case of removing the rear engine mount bolt:
Image

Image

And the front one:
Image

Then a block of wood under the sump and used a jack to jack the motor up. Carefully and slowly jack the motor up, keeping an eye on any pipes or wires that might get pulled or squashed.

Voila:
Image

Motor lifted by about 50mm:
Image

Screwdriver in one hole on the pulley to stop it from moving to loosen the 3 bolts that hold it onto the pump:
Image

And:
Image

3 more bolts to remove and the pump can be taken out of the block:
Image

New pump and the old vrot one:
Image

O-ring lightly greased (new O-ring is provided with new pump):
Image

And in it's new home:
Image

New tensioner with bolt to move the arm to make fitting the tensioner easier with the belt (you can see the difference):
Image

And all done:
Image

Now refill the cooling system with fresh coolant, have a beer and congratulate yourself on saving a good few bucks by doing it yourself.

Started at 12:58pm and finished at 2:30pm and that included a half an hour break for some sarmies for lunch.
1 hour job very easily.
