T5 Post Icon Water pump Seized in to the block 2.5 AXD 2006

Hi all,

Having a bit of a nightmare and could do with some help. was drving along and the coolant got dumped in the the oil, quickly diagnosed it as a failed water pump. i now cant get the pump out, i have stripped everything off and have plaved the extraction tool over it. i put so much pressure on it i have broken the tool a number of times and then had to reweld it stronger than before.



i have tried everythig left it tensioned for DAYS no joy, sprayed it with WD-40 i have just heated it with a mag blow torch to see if it will come no joy. im now at my whitts end. unless i can get it out soon im thinking im gonna have to drop the engine to attack it further

Sounds bad, im considering doing mine at some point.

If Ive understood the design right its a circular pump in a circular aperture?

What about a bar drilled and bolted across the bolting points to apply some rotational force? Enough to break loose any bonding, or would the risk of cracking the bolt points on the pump casing apart be too much?

Break its bond loose then pull it basically.

its hard to explain without seeing it but yes your discription of the pump and housing is correct. There is very little working room for a start and it has been tourqued to hard it breaking tools despite even being heated. im going to start stipping it down this evening for the engine to come out.

I recognise the van now from the build thread you did last year. I see you've got access to a ramp, but it might be worth changing the starter motor while you've got the engine out. It's a pretty fiddly job to change it with the engine in the van. I think you've said before about the gates couplings, but worth changing them at the same time. Well done for taking it on

Check everything, manifold studs and any cracks, do the gates couplings, yes perhaps starter. Even things like 2x CTS sensors (one on block under manifold is not easy to reach usually), thermostat, check your turbo and health of its mounting gasket (oil seal) and remember to renew the donut gasket etc

Anything you can do to save time and hassle later.

I'd even consider rocker cover off and a good inspect of the cam and followers, maybe even the injector bores.

Don't forget to replace the freewheels on the alternator (and A/C if you have it.)

Well to say i had problems getting this pump out is an understatement. I spent 2 weeks and I almost threw in the towel, i spent days heating cooling trying to pull it out when eventually the shaft from the pump came out and i was left with just the race which i couldt cut. I ended up today welding a towing eye in to the race and using a highlift jack on the engine in an attempt to remove the pump. still no joy but under massive load i began to hit the eye with a hammer and the race began coming out with every strike. after removing the race i then cut through to the 2 10mm holes i drilled close to the wall of the pump housing and had to beat and break the pump out bit by bit. it was a horrible job and i really thought it had beaten me.

after i removed the old pump i cleaned the rust from the inside of the pump housing using a die grinder and offered up the new pump and it seems to fit well. As the engine is out i will be doing a few small jobs and hope to have the engine in by next weekend
















Look at the bend under load



















All done

Strewth. You have just leapt straight to the top of my “most determined people” list.

I hope the repair and reinstall goes well.
