How to to replace waterpump without removing the cambelt. Hopefully will dispel some of the myths that you need to take the cambelt off to replace.
What you need:
Various sockets, namely 10mm, 12mm, 13mm, 15mm, E8 star socket
Waterpump: Ford Part 1566239 circa £100
Jack
Block of wood
Axle stands
3l undiluted Anti freeze
Screwdrivers
12mm and 13mm spanner
Torque Wrench
Guide:
Start by jacking the car up and placing on axle stands.
Drain the coolant by undoing the plastic bolt in the bottom right hand corner of it
Remove the weathershield
If you look under and up you will see thisis held in my 2 8mm bolts, remove them
once free look behind the plastic and undo the hose from the clips
Withdraw the shield from the car
Next job is to loosen the 4x 12mm nuts on the waterpump pulley, makes it easier to do while the belt is still on, the pulley may still try and spin though like it did with me, however i wedged it with a screwdriver placed across the bolt heads.
When those are loosened its time to remove the drive belt
Take your 13mm spanner and place on the tensioner bolt, act as though you are turning the bolt in an anti clockwise direction and the tensioner should move freeing up tension on the belt
I find it easiest to pull the belt off the waterpump pulley
once the belt is free undo the bolts on the waterpump pully fully, and remove the pulley
Remove the alternator which is held in my 2 15mm bolts and a 13mm you need to remove the bolts pointed in the diagram below, and the 10mm holding the power terminal on
15mm bolt hiding round the back here
You can then withdraw the alternator
Remove the 10mm bolt holding the idler pulley on
Remove the pulley
Next up we need to remove the cambelt cover, there are 9 i think, 10mm bolts holding that on
Its easier to show you there whereabouts on the removed cover
Remove from car
Now we need to drop the engine on that side to get better access, i thin kyou could probably do it without diong this but it makes it 10 times easier and also means you dont have to have an exact length extension bar for access
support engine with block of wood and jack
Undo 3 15mm bolts here on the mount
Then the 3 threaded bars, that are undone using the E8 star socket
GENTLY lower the engine to give you better access to the waterpump, viewed from underneath the car
There are 6 10mm bolts holding it on, the first threee are easiest undone from above, the rest from underneath, again better to show you where they are on the removed pump, this is pictured in the same orientation it is when attached to the car
try and avoid damaging the cambelt undoing some of them on the extreme left, also bear in mind when you undo them all water will drip from it
When all are out you can remove from the car, be aware excess water/coolant that doesnt get drained will fall out from it
withdraw from car
clean up mating face etc
Then fit your new pump and gasket on in reverse order to removal.
Bear in mind the following
Torque the nuts on the new waterpump to 9nm
Torque the nuts on the waterpump pulley to 25nm
When refitting the belt fit around the pulleys depending on your configuration below
If im doing it on my own i find easiest to wrap around all the pulleys and leave the power steering pump until last, then slacken the tensioner and push over the pulley.
Make sure the belt is seated correct on all pulleys, there are groove for the ribs in the belt to sit in. Worthwhile giving the engine a turn over with a 19mm socket on the crank pulley to check its all seated ok.
If all looks good refit the weather shield.
Retighten the radiator drain plug, and fill back up with coolant 50/50 mix, 3l of coolant 3l of water.
Let car warm fully with cap off expansion tank squeezing coolant pipes, letting any bubbles come out, recheck level and correct as necessary. Check water levels for the next few days of running.
Disclaimer: If you have aircon there may be an extra step early on to remove an extra pulley, i think the powersteering pulley also needs to be removed also on aircon models only
