P38A Replace water pump

RangeRoller dt · Jan 23, 2020

fan is a likely one I’ve seen few similar stories. You do know it’s reverse thread?!?
I had the same with belt tensioner it’s just one of them things
Luck of the draw and you’ve been unlucky on this one.

Mark tried to get few free sausages and it cost him big time. Front end damage went to insurance to be fixed, they cocked up his bus and damaged it.
Was lucky to get it back before they molested it any further. I wouldn’t of wanted to be the guy handing the keys back over to Mark, man with a broken heart like that will kill

Nightmare for Mark. Yes, I did know it was reverse thread. Even used the special tool holding the pump still so you an get some force onto the fan nut - and some real welly with a lump hammer on the fan spanner - just bent two fan spanners.

At least I got a refund from halfords for one of them.

Put some copper seize on the threads before you remount the fan - then it will come off like a dream the next time. Now I can just use a rubber strap wrench to hold the pulley to get the fan off - although I broke the strap the first time round

) the last guy torqued it up

Blue Hylomar is the best sealant on the planet.

I used to think that, but it doesn't seem to go so well on gasket-free joins. The stuff i used on my inlet manifold (GEMS, no gasket), on inspection, just dissolved to nothing, leaving an oil residue behind. RAVE recommends Loctite 577 for the inlet manifold, and when you look at the spec it is a plumbers' threadlock, so I'm gonna play with this now (reassuringly expensive too). Obviously with a gasket the hylomar at least has something to hold on to, so then the maths changes

You are wrong it is especially designed for gasket free joins on Rolls Royce jet engines. It needs to be applied correctly.

Your choice, all i'm saying is that Hylomar Blue is not always the best option in a LR, and the LR engineers seem to agree. Fine for the water pump though.

BTW Nick, make sure it's an Airtex pump
