Thanks, will order that so can change plus already have the two seals for oil pipe

For the cooler itself, do I need any extra gaskets or comes with it, assume just the bottom one required as its whole cooler so don't need the one thats inside it, wasn't following what you meant, thanks

Hi, depends on what you buy, the Nissen unit I bought came with the rubber gasket already fitted so no need to buy an additional one.

In the diagram below the oil cooler (4) itself sits on a intermediate assy (5)(EGR Cooler), if your just replacing the oil cooler because it is leaking, whic is the most common, then you only need to go down as far as removing item 4. If your leak is furtherdown then you'll need to also remove item 5 and replace the gasket under there.

I just did the oil cooler itself and the gasket between item 4 & 5 was already fitted to the base of item 4.





The 2 small pipes folks talk about connect on the right end of the cooler itself in the diagram, it is possible to replace those with the cooler in place but it's really fidly and largely blind activity. If your removing the cooler anyway you can do it then easliy.


The water connector is the one you can see on the right of the cooler assy, the connector itself and the O ring in pics below.

cheers very much for the advice, qq, do I need to drain the oil or coolant or just a bit comes out I am seeing. I have bought the draper oil extraction tool but it has not come yet, however cooler and seals are here so can I do this without draining anything as might get fired into this tonight and tomorrow. I notice the new cooler has new oil filter assembly on, assume there a filter in it (should I check I wonder), and I have spare filter to change oil after so ideal to change cooler, get it running, check for leaks and do oil change after. Also similar with coolant, leave it filled, take a bit of spillage and change that again? many thanks

Hi,

I changed the oil and filter after changing the cooler as I could not be sure that I didn't get any water contamination in the oil.

I was doing a full service at the same time so I did replace the coolant, but I'm not sure you'd have to, but probably best as oil may have seeped in there.

Got start on this earlier, about point to release water pipes and unbolt cooler, not been to bad to this point, tip to cut short these little studs helpful, I found by cutting one plate comes off ok. Noticed got some not terrible oil stain round throttle body and air inlet pipe, inside intake pipe was just the normal light smear of oil you get through intercooler so don't think its from there. Could this also be from cooler but getting sprayed forward on occasion or suggestion where common leak. Pic is from drivers cylinder bank but actually bit more on passenger bank, not really soaked looks partially dried up which made me wonder if it just a little from cooler also. Will post progress if get back to it tomorrow. Have also removed the battery (bit of a faff also) to charge it since car sitting. Will stick pics up tomorrow to help anybody else doing this, hopefully go smooth, thanks

pic of top of cooler, have a look, wetter at back but generally all around

Well, got it off short while ago, but disaster as I was removing it I leaned on what looks like top bit of thermostat housing or something and broke off small bore pipe at top as in picture. Its the other end of the pipe thats prone to snapping off as you take inlet pipe to throttle body pipe off. It looks like the top bit unbolts what is it and can it be bought separately or am I looking at whole thing

think it called bleed pipe, LR023142, assuming I am probably the only idiot who has managed to snap this off before. But if anybody has taken that off before does it just unclip on wee tangs on either side?

Just done mine. I think it is LR022690. £54. Comes with the two outside hoses and sensor.
Sorry I'm wrong there. Yours has broken on the hose.

I didn't have a lot of coolant come out when I did mine, probably because I used my electric oil pump to drain out as much as I could from the header tank so the level was probably below that of the cooler.

But you should drain all that oil and coolant from those journals as that's where the contamination is most likely.

Shame about the pipe, especially when things going so well. I just did pads & discs replacement and sheered a bleed nipple, still trying to work it out, but most likely it's done for and I'll need to spend a heap for a new caliper and the cars now off the road.

At least I enjoyed a trouble free week having got my wafting ride back after replaceint the height sensors.

Love the Range Rover world, never dull that's for sure.

Cheers

yeah AndyRoo, I always seem to create new jobs whilst working on them, lot of plastic these days. Bleed nipples in calipers can be nightmare, I have one of these induction coil heater tools, cant recommend it highly enough for them. I have a old 944 turbo with Brembo calipers, 2 nipples in each alloy caliper and most snapped, working way up drill sizes works, suggest you try that, they usually release way before you are hitting the metal of the caliper body, nipples only threaded 2/3rd length so can go shallow, patience, got loads out like that, certainly worth a try with some good bits before scrapping caliper, assume its the big 6 pots on yours?

As for my night I kinda spat dummy and called it quits for the night after my wee screwup, covered top engine with bit cardboard so nothing falls down and I'll get back to it the morrow, despite breaking that pipe I think I can stick cooler on and it wont be in way. Just ordered the LR022690 whole top unit from AF (thanks kevinp) was only £30 odd, noticed they had the hose with clip on it listed separately LR023142 for tenner so ordered that as well and can try just changing that as if cant or it breaks I will have whole unit to go on anyway, there was nothing wrong with cooling system and until tonight it seemed to have to leaks till I leaned on it, so might try that. Kevinp don't suppose you happened to look at the old one you replaced and know if that wee 90 degree pipe comes out easy?

Forgot to say Kevinp, anything I need to watch out whilst changing that housing or did yours come off ok, etc? thanks again all, really appreciated, great forum and I will try contribute when I can, great help

I was doing the oil cooler first and honestly my hand just brushed past that hose and it broke.
As I was changing the full thermostat housing I honestly didn't look at how that pipe comes off.
I think you just press the 2 barbs in on that one.
Just be so carefull with anything that has a plastic fitting that any of the hoses go into!
My thermostat housing temp sender was leaking so I replaced both halves. It was literally crumbling as I removed it.
