Hi all, Whilst trying to get to the bottom of my overheating issue on my V6, I've noticed some rather bodged hosing work that's been done in the past. The pipe I'm referring to is the one marked in green below, I know it's only a return pipe to the expansion tank but surely it's not right...

Will have to get another O ring, as I've managed to shred this one trying to get it into the block !!! ARGH !!!

It's a new Elbow pipe with new O ring... The O ring is on the pipe, it's just I can't get it into the hole in the block !!!!

Thanks Tony, the problem I'm having is the bit that says "fit coolant elbow into cylinder block, press firmly into place" !!!! It's too big !!!!

Yep, tried that ! Not getting close though ! Just seems too big for the hole in the block ?....

Can anyone help, I just can't seem to get this into the hole, the O ring just doesn't go in ! Anyone any advice on an easy way to get this in?

As for the hoses, the Top Rad hose stiffens and is very hot, as for the bottom hose, although does stiffen up, doesn't really get warm at all.....

Thanks... I did get air out of both but I've had to drain it again as I discovered a leaking O ring on the Thermostat Elbow pipe (that was the strange "squelch" Hippo in one of my earlier posts)... Could be why it wasn't building up pressure? Wasn't a big leak at all though !!!

As far as I can tell yeah ! What's the best way I can confirm ?

After about 10 minutes, the expansion tank starts to boil over ! I've bled the system to the letter too (a few times) ! Also changed the thermostat (confirmed as working), various hoses, the expansion tank and cap (both pressure tested), temp sensors ! No idea what else it could be?

Hi Tony, yeah I've got another one on order, was just wondering if this could be the cause for my overheating issue?

hi everyone, quick question, looks like I have a leaking oil cooler, would this potentially cause my V6 to overheat? :confused: Thanks

Thanks Hippo, looks like this is the one, superseded by PEH000340, found one on British Parts ! I was confused by the description : Cooler to Thermostat Hose o_O Cheers

Hi everyone, getting to the bottom of my overheating V6, slowly but surely ! Need some help identifying the correct part, I need a new hose (as its leaking), it's the one between the oil cooler and the transmission cooler, I can't seem to find it though on British Parts or Rimmer Bros, can...

I've not had it long at all, about 3 months and had problems with overheating since I bought it ! So far I've changed the following: Thermostat Various Hoses Expansion Tank Expansion Tank Cap Coils Injectors Bought a new water pump but not yet fitted Actually, re the oil filler, it does look...

Also, on the black "deposits" in the expansion tank. On closer inspection at first they appear to be black, however when I scrap some out and them rub in my fingers they do actually have a red/brownish tint (a bit like rust), could this be a problem with the transmission cooler (and actually be...

Thanks for the advice everyone... I've checked in the V and there is definitely no evidence of a leak in there. So it must be somewhere else ! Also, when I squeeze the bottom rad hose, the strange "squelch" is definitely coming from within the V area, so I'm thinking it must be either the new...

Right, system bleed (to the letter as per instructions) and it seems like I still have a problem as after just on 7 minutes (as per the bleed procedure) it starts to boil over in the expansion tank ! Can't see any obvious leaks however when I squeeze the bottom Rad hose, there is a sort of...

Also, what would explain the black deposits in the expansion tank?

Thanks Arctic2, I've checked in the V and its bone dry, so I'll fill it up again with coolant as you suggest and start it up ! Is there anything obvious it could be though ? Maybe could've been an airlock (might explain the bubble noise I heard)?
