dangerous doug Posted November 14, 2015 Share Posted November 14, 2015 Having big problems with my 200tdi to 3.9 conversion.....again! I'm using a defender TD radiator as its full width and has the built in oil cooler. I bought this removed my old cooler fittings put them into the new rad and the cooler pipes on to them. No problem. The rad started leaking coolant so it was sent back under warranty but couldn't get those fittings out of the rad with out totally destroying it. I then find the manufacturers have just skipped the rad without removing my fittings i had to buy new fittings which I was told were NCT3858 which fit fine in the rad but not on the oil cooler pipes.... Anyone have any ideas on other adapters? truck is obviously immobile so I can't take it anywhere and I dont understand why one would fit and not the other! I dont want to put a little mocal on it as I've already spent £320 on a new rad with a cooler! Quote Link to comment Share on other sites More sharing options...
teabag Posted November 14, 2015 Share Posted November 14, 2015 As your dealing with something that's non standard as this link shows no adaptors involved maybe u could find something at a plumbing, hydraulic supplier. http://www.allbrit.de/UNI.cfm?PAGE=808001&SPRACHE=EN Quote Link to comment Share on other sites More sharing options...
dangerous doug Posted November 14, 2015 Author Share Posted November 14, 2015 That's what I'm resorting to. I'm pretty sure the v8 side is m18 male just need to know the thread of the oil cooler in the rad some google searches show up 1/2 bsp but I'm not sure Quote Link to comment Share on other sites More sharing options...
dangerous doug Posted November 14, 2015 Author Share Posted November 14, 2015 Bizzarly the bolts I ordered by mistake for something else sort of fit..... They are 5/8 UNF Be patient with me as I barely know about metric fasteners but could the rad side of the fitting be 5/8 BSP? From the top: 5/8 UNF bolt NTC3858 V8 transmission cooler fitting suspected m18 which fits the v8 pipes Quote Link to comment Share on other sites More sharing options...
lo-fi Posted November 15, 2015 Share Posted November 15, 2015 I believe the rad in the 3.9 disco donor I used had 1/2 bsp fittings for the oil cooler. These measure 0.825" OD at 14tpi. Don't forget that BSP size names don't relate the the thread size: http://www.motalia.com/Html/Charts/bsp_chart.html A bit of measuring ought to reveal what you're dealing with Quote Link to comment Share on other sites More sharing options...
dangerous doug Posted November 15, 2015 Author Share Posted November 15, 2015 Cheers fella, I'll have a look later Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted November 15, 2015 Share Posted November 15, 2015 To find out if its 1/2" bsp, try screwing a shower hose or the nut from a 15mm compression plumbing fitting on to it. Mo Quote Link to comment Share on other sites More sharing options...
dangerous doug Posted November 15, 2015 Author Share Posted November 15, 2015 Ah cheers! that's an awesome little trick, just tried it on the shower (don't tell SWMBO) and spot on! Only problem is that's not the problem end However using the chart posted by lo-fi I'm 99% sure that the rad side is 3/8BSP and the oil cooler pipes are m18x1.5 M18x3/8BSP male male adapters are £5.90 for the pair! Just got billed £55 for the genuine fittings which will be going back! Now we wait..... Quote Link to comment Share on other sites More sharing options...
