Bigj66 Posted October 31, 2020 Share Posted October 31, 2020 My oil cooler is part number PBC000020 (P38 after YA4455076) and the two connecting hoses are listed in the parts book as PBP500260 and PBP500270. I ordered two of the PBP500260 pipes as I just need the two cooler side female ends for my project. When they arrived they came with M18 female threaded nuts and not the M22 ones that the cooler has. There’s no sign of any adapter between the two in the parts manual. Can any P38 owners shed any light on the correct parts that I need?

Blanco Posted October 31, 2020 Share Posted October 31, 2020 I'll have a quick look under mine in a minute, but my parts book has PBC000020 as diesel manual cooler, and the corresponding pipes as PBH101750 and 760??? Quote Link to comment Share on other sites More sharing options...
Blanco Posted October 31, 2020 Share Posted October 31, 2020 Mine being late model auto is different again, 20mm threaded bosses on mine, seems they are all different. Quote Link to comment Share on other sites More sharing options...

Cheers I’ve not come across those hose numbers before so I’ll check 👍 Quote Link to comment Share on other sites More sharing options...
Blanco Posted October 31, 2020 Share Posted October 31, 2020 If you get the right parts lad at Craddocks I am sure they would double check them for you before dispatch, just so that you don't end up testing all the hoses.📏 1 Quote Link to comment Share on other sites More sharing options...

Out of curiosity, does yours have both threaded bosses on the same side? Quote Link to comment Share on other sites More sharing options...
Blanco Posted October 31, 2020 Share Posted October 31, 2020 Fairly close, ... one on the bottom I think and one on the inboard side, but yes both really on the inboard side. Quote Link to comment Share on other sites More sharing options...

Blanco Posted October 31, 2020 Share Posted October 31, 2020 Right, excuse the slight delay, your pic had me scratching my bonce.... went back out and realised I had been ooking at the transmission cooler! so investigated a bit further and this is my engine oil cooler, tucked in between the intercooler and the condenser I did try and get the caliper in there but its pretty congested, I made two guages out of plastic and I am fairly sure its 22mm rather than 20mm. rigid pipes are a shade under 17mm. Both fittings are on the LH side of the vehicle and the unit. Quote Link to comment Share on other sites More sharing options...

Escape Posted November 1, 2020 Share Posted November 1, 2020 I've had a look at the partscat and through memory lane 😉 to see if I could find anything useful. There are indeed 2 types of cooler, before YA (with several superceding part numbers) and from YA on. But the pipes should be the same, PBP500260 and PBP500270. The O-rings in the connections are all the same, so size/thread should be the same on both coolers. Could the cooler you have be an aftermarket one? I don't have a late P38 in at the moment, but could ask to have a look at a mates. Filip Quote Link to comment Share on other sites More sharing options...

Filip It aftermarket in that I bought it from Bearmach but I’m pretty sure it’s correct as Blanco has the same on his. LR must have made an earlier version of that pipe but if they are no longer available and have been superseded with the M18 version then why are Bearmach still selling them? 🤷♂️ I’ll need to call them tomorrow and find out. This is mine with a brand new PBP500260 pipe against it. The rigid pipe and seal fit inside okay but the nut is just too small 🙈 Quote Link to comment Share on other sites More sharing options...
Escape Posted November 2, 2020 Share Posted November 2, 2020 I can't find any reference to a different earlier or later pipe... Strange. I'll be working on a DSE today, I'll have look and measure the threads. Filip 1 Quote Link to comment Share on other sites More sharing options...
Bigj66 Posted November 2, 2020 Author Share Posted November 2, 2020 News from Bearmach is that the part numbers for the two pipes are PBP101240 and PBP101180. NLA from LR🙄 Still available as aftermarket though so will order one in to check. Quote Link to comment Share on other sites More sharing options...
Blanco Posted November 3, 2020 Share Posted November 3, 2020 To add to the sum of info on the engine loom I have two pics showing the layout for the diesel, Main engine loom emerges from the FIP, down on the RH side of the block as viewed, under the inlet manifold, crosses the engine on the support at the front and goes through a large grommet into the ECU box, it terminates in the large rectangular clip on connector that mates to the ECU. Close up of the top of the ECU connection, it just lifts out of its box, normally held under a screw down cover. 1 Quote Link to comment Share on other sites More sharing options...

David Sparkes Posted November 3, 2020 Share Posted November 3, 2020 1 hour ago, Bigj66 said: Definitely different to what I have here, cheers 👍 The picture is one of the later versions, with a black plastic inlet manifold that conducted less of the high underbonnet temperature into the air being fed to the cylinder head. The earlier inlet manifolds were cast aluminium. The manifolds are not directly interchangeable as BMW moved the mounting studs in the cylinder head when they adopted the change in manifold design.

I looked at the diesel in the Workshop yesterday, the fittings are indeed M22. Strange... 1 Quote Link to comment Share on other sites More sharing options...
