How important is it to change the water pump. Not usually necessary!

Not necessary but while you are there you might aswell

[Gandi699]

Also adds loads of time to the job as that water pump will not come out without a fight (ie: smashing it until it breaks and frees it grip on the block). Worth doing still though mind

I was terrified that mine would do that, but I just put a screwdriver on the flange and hit it with a hammer so it was trying to spin the pump in the block. Did that and when it broke the seal it near enough drove itself out.

I was hitting the impellor on mine for about 45 minutes with a hammer via a big bar. I find chipping the flange off where it bolts to the block is what should be done first then just persevere with it, eventually it does shift but its just such a tight fit in the block that makes it a pain.

the engine i bought for my conversion had a new timing belt on it just before i got it. put it in the car and 200 miles later the water pump went. its not necessary to change but for the hassle you may aswell just do it

Thats true. Is there no way of seeing that it's fine. If the bearings are all smooth and there is no play there shouldn't be an issue. Just to save a few quid!

I just put a screwdriver in between the pump and the block and it came out with ease.

Must of just gotten lucky. lol

Yeah you were there, they are generally a pig

i thought this was my old thread......and it was

Thanks for the guide it has helped me loads. Any chance you could do one for changing a head gasket.

Lol not as of yet mate. But i can tell you what you need to do

[brewer]

Thanks, I have a couple of questions. Do you need to take off the exhaust manifold as I don't fancy breaking the studs as they are rusty. What is the best way to clean the surfaces up before fitting the gasket.
I appreciate your help. As I live just outside Leicester it's good to know someone I can get advice from

Either you can take the exhaust manifold off (but id wd40 the studs and leave overnight first) or you can disconnect the downpipe from the manifold and remove the head with the exhaust manifold still on the head, but this just mean its more fiddly to handle(and heavier), and i always clean the head and block surface with fine emery paper, sort of 120grit or smoother, as this way it cleans the head surface and leaves it very smooth, to rougher sandpaper will score/scratch the surfaces. Just make sure you clean properly around the area where the sealing rings on the headgasket will sit (around the cylinder) and use something like carb cleaner to clean oil film from the head and block surfaces before fitting the new headgasket

[brewer]

Well al done and everything ok. Thanks for your help. Now onto the brakes

[stowie44]

First of all I must compliment your guide, its excellent. I'm currently changing the cam belt on my 03 plate vtr. Everything seems to be going well apart from one thing...

When I manually align the belt and turn the crank with a ratchet everything aligns fine. However when I start the car the belt immediately pulls to the edge of the cam (as shown in photo).



I'm using a dayco kit with new tensioner.

I've tried the old tensioner too, same problem.

I've tightened the tensioner a little more, I've loosened the tensioner, always the same problem.

Any advice would be much appreciated!

[konark]

If the belt moves towards the outside of the cam sprocket when turned ( or when running) it can mean that the water-pump bearings are on their way out leading to play in the water pump sprocket. The tension of the belt then makes it wander to the open end of the water-pump sprocket , and to the outer edge of the cambelt sprocket.

Grab the water pump sprocket and try to push and pull it sideways; if there is any significant movement fit a new water-pump as this will only get worse with use.

[SneakyPeakey]

going to attempt this myself, going to change the belt and water pump in one go, just wondering if i will need the whole water pump housing or just the sprocket+impeller section? Great guide by the way, very detailed

[swys]

hi great guide very tempted to do my saxo 1.1 hfx engine but I gather there is an auto tensioner on newer engines?
