Hi Neil, yes it's a daunting job. I have not done mine (had it replaced when I first bought the bus). It's certainly a big process for what is a straight forward job on other engines.
I have found with the hose clamps you can get stuck with orientation if they are installed when the engine is out or exhaust off which might give you a different access point.
Glad you got it out and it sounds like it's all looking good inside so far!
It got my hoses from Van Café, and have been happy with them. When I got my kit only a few were silicon. I think their kit is mostly silicon now. Have not heard any bad reports from silicon hoses yet and the few I have are all good. That said many of the hoses I replaced were originals, so lasted a good life.
I would recommend getting a kit from somewhere reputable. Many of the hoses are molded to a shape, you would get kinks in the hoses if they were not in the right shape.
Yes, definitely worth doing the cooler hoses also.
If your doing the oil switch there, Check the adaptor it screws into for leaks around the thread just in case. I'd also recommend replacing the wire to the switch. They get brittle with age. Again good vendors sell this wire ready to go also if you don't want to make your own.
Regards,
Richard

Hi Richard,
Just replacing my water pump, fun isn't it!
I was just trying to look up old posts on any tips or advice as am finding it incredibly difficult to access bolts and clamps.
As soon as I remove one bolt or hose clamp I come up against another that appears impossible so I sleep on it and think of a solution and remove it the next day only to come up against another worse one.
Whoever worked on the vehicle before seems to have managed to tighten up all the clamps in such a way that you can't access the clamp bolts or get pliers on the spring tabs to loosen them!
I now have the water pump out and also got the coolant crossover pipe under the crank pulley out, (I thought this one could not be removed without removing the pulley but after worrying it around for half an hour it just came out. Like one of those wire puzzles.) I hope it goes back in again.
The water pump also took some time to worry out past the coolant crossover pipe.
All the pipes and hoses appear to be in very good clean condition with no rust.
This job is so much fun though, I would like to replace all the hoses and maybe the oil pressure switch too while it is all out, hoping never to have to go there again.
Any tips on where to get all the hoses?
Is it OK to just buy it by the metre and cut to length or are the molded curves required?
Are silicone hoses a good upgrade?
Thanks,
Neil.

Thanks Ken, good to know. The water pump is not that old, and everything was good then. Always had original coolant and everything I have looked at so far has been in great condition. I'm really just replacing everything to prevent issues in the future, I've had no issues with it to date and cooling has always been good, even in QLD heat and AC running. I'm planning to keep all the parts removed as just in case spares.
I think it's best to leave that pipe unless something looks suspect. No signs of rust any where.
I'm also not replacing the two cross over pipes above the bell housing, I figured mine is fine, and simple to relace if it ever needs it.

Hi Richard,
It's pretty much standard procedure now to replace the water pump without first removing the 3x output pulley. However, in that scenario, given the pulley is still in place, that WP R&R procedure does not enable removal of the steel coolant crossover pipe.
If you ever need to work on the oil pump, (in terms of accessibility), perhaps in conjunction, that's a time to consider the possibility of replacing the crossover pipe with SS. Or else whenever the the motor is dropped out.
spots
Then again, maybe your crossover pipe is in good condition anyway. No sign of rust spots?
Interestingly, way back, I had rust showing in a number of spots on the big steel coolant pipe (passenger side of motor), but no evidence at all of corrosion in either of the crossover pipes ... water pump one or firewall one. Still no sign of rust in them
ever since either. So maybe you are worrying about a problem that does not exist. With an exception, .... unless your van has previously had the wrong coolant in it of course.
So yes, you should be able to do all the coolant system R&R in situ without removing the pulley, except R&R the water pump crossover pipe.
Cheers.
Ken

Thanks Hart,
Yep, two reason's I'm not keen to remove the pulley, don't want to risk damaging the seal as it's currently not leaking, and what you need to remove to make room for a puller!!
I guess I can see how far I get with the pulley in place, and make a call if I need to replace the bits I can't reach. I'm hoping with the AC out of the way, it's only the pipe from the water pump to the RH head I can't get to. If everything else is in good
nic, I can just leave it and replace when the water pump needs doing.
No, not this week end, still a few weeks before I get into this. Been a long time coming, and still waiting on a few bits to arrive.

Hi Richard , for my last one i needed a puller. In that case you might want t remove the heat shield as well as the exhaus same time check the expansive double lib oilseal for leaking ?
Looks like your wend is booked!
