2002#3 Posted August 18, 2022 Share Posted August 18, 2022 E21 M10 block Behr Radiator (year? series? not BMW?) (Photo 1) Lower Radiator Hose (year? series? not BMW?) (Photo 2) I have a LRH rubbing against the frame and looking quite nasty. LRHs for 2002s sand E21s don't look like they will fit b/c the radiator outlet is on the side. Q: Any suggestions re: a hose which might have the correct bends, shun the frame, and fit the ticket? Looks like it might need >4 bends. the BMW series (IF it's BMW) from which the radiator was obtained? That info might help me find a suitable hose. Thank you.

Son of Marty Posted August 18, 2022 Share Posted August 18, 2022 I'd take that hose to Napa they'll have a several hundred page catalog of just water hoses complete with drawings and all measurements. It looks to me like the radiator is mounted to far to the right and you'll play hell to find one with a shorter lower bend than that one, I'd think if you moved the rad over a inch or two that hose will work, obviously you'd need a replacement. 1 Quote Link to comment Share on other sites More sharing options...
Mike Self Posted August 18, 2022 Share Posted August 18, 2022 Looks like an E21 radiator. If you can't find a hose that will work without rubbing the frame, you can always clamp a rubber or soft plastic sleeve around the radiator hose to keep it from rubbing against the frame rail. I had an A/C hose rub a hole in itself where it chafed against the other A/C hose running along the same path. Once the hose was replaced and the system recharged, we insulated the two hoses wherever they touched at the clamps. mike Quote Link to comment Share on other sites More sharing options...
bergie33 Posted August 18, 2022 Share Posted August 18, 2022 (edited) Might be an E21 automatic transmission radiator. I think those have a side exit lower hose like that. Is the hose like this one: https://www.ecstuning.com/b-uro-parts/lower-radiator-hose/11531266956~uro/ Edited August 18, 2022 by bergie33 1 Quote Link to comment Share on other sites More sharing options...
Son of Marty Posted August 18, 2022 Share Posted August 18, 2022 (edited) It doesn't look like the e21 auto hose. It's missing the 90' bend at the lower end. Edited August 18, 2022 by Son of Marty Quote Link to comment Share on other sites More sharing options...

I don't know how accurate the drawing is for the shape of the hose. Maybe see if you can find a pic online based on the part number. Quote Link to comment Share on other sites More sharing options...

2002#3 Posted August 19, 2022 Author Share Posted August 19, 2022 I cannot fine any 3 series LRH which will suffice and the drawing is nowhere close to accuracy. My hose has 4 bends in one direction and 2 in another direction. The outlet emerges directly from the side and toward the wheel well. A past owner found a workable hose somewhere, so, it looks like it's O'Riley's, AutoZone, etc. for me. I looked up "BMW 2002" in a thesaurus and found only "adapt", "modify", "make do", and "good luck". Quote Link to comment Share on other sites More sharing options...
John76 Posted August 19, 2022 Share Posted August 19, 2022 You might be able to avoid the chaffing if you trim the two other hoses a bit to move the t-stat closer to the engine. Just a thought ... John 1 Quote Link to comment Share on other sites More sharing options...
TobyB Posted August 19, 2022 Share Posted August 19, 2022 (edited) My Frod came from the Frodplant with an anti- Chaffee cover on its upper hose. Me, I'd go thataway. And move the radiator thataway, too. And notching that pinch weld won't cause any problems, either, if you put a bead of weld along it. It's only flanged to make it easier to assemble. t Edited August 19, 2022 by TobyB Quote Link to comment Share on other sites More sharing options...
jimk Posted August 19, 2022 Share Posted August 19, 2022 For my anti-chafe guard, I used a length of radiator hose slit lengthwise and zip tied over the hose to protect. It will last the life of the car. 1 Quote Link to comment Share on other sites More sharing options...
2002#3 Posted August 19, 2022 Author Share Posted August 19, 2022 Looks like 1/2 the hoses are interloper miscreant forced workers. Time to breach the cooling palace walls and replace all four guards. 1 Quote Link to comment Share on other sites More sharing options...
2002#3 Posted August 23, 2022 Author Share Posted August 23, 2022 Mystery Hose Radiator hoses from '89(?) radiator to '75 block do not exist (Duh!). One hour of browsing at NAPA yielded two hoses which looked close: late model Ford Escort and Mazda 6. Upper fit well. Lower was cut, reduced, twisted 180 degrees, and spliced. No leaks. Good to go. Cheap, old "open slot" clamps with be replaced with new "closed slot" clamps later. Quote Link to comment Share on other sites More sharing options...
Hien Posted August 23, 2022 Share Posted August 23, 2022 Just for your info, the fuel filter should be mounted before the fuel pump. Nasty stuff in the gas tank call (rust)can ruined that fuel pump and leave you stranded. 1 Quote Link to comment Share on other sites More sharing options...
