Mo Murphy Posted March 28, 2019 Share Posted March 28, 2019 Evening all, Does anyone know if STC635, 21/2 up to 19j is the same as and can be used instead of STC639 for Defender 200 Tdi ? The reason I ask is that I know they have the same sealing footprint, STC635 is available from Airtex, the OEM supplier but STC639 isn't. As I thought would be good practice, I replaced the genuine old reliable pump when I changed the timing belt with a new one Turners sell (I don't know what brand) but it's lasted less than two years. Funds don't stretch to £270 for a new genuine pump but Airtex seem to have always been highly regarded, hence my question 😊 I have read Mavericks thread where he used a 200 pump on a 19j but can't find any reports of vice-versa. Failing that can anyone recommend a reputable brand for STC639 ? Cheers Mo Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted March 29, 2019 Share Posted March 29, 2019 I can’t answer your above question Mo but shop4auto parts do a stc639g made by Pro Flow for £50 don’t know if that make is any good , but says made in the uk and I’ve not used them personally yet but everything else I’ve had off there site has been good . 1 Quote Link to comment Share on other sites More sharing options...
reb78 Posted March 29, 2019 Share Posted March 29, 2019 I had a look on the Turners site and Proflow is what they sell so sounds like the make Mo is trying to avoid. Never heard of them before. How did it fail Mo? Quote Link to comment Share on other sites More sharing options...
Maverik Posted March 29, 2019 Share Posted March 29, 2019 Hi Mo, I think they are one but the same. and this link also points to the same conclusion... https://www.johnrichardssurplus.co.uk/water-pump-kit-da2135.html 1 Quote Link to comment Share on other sites More sharing options...
reb78 Posted March 29, 2019 Share Posted March 29, 2019 I might have a pump from my old TD in the garage Mo (i keep old carp!). If I can find it, the week after next, we can compare them side by side. 1 Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted March 29, 2019 Author Share Posted March 29, 2019 Morning chaps, Thanks for your replies. Ian, I saw those on my searches and did note that they come with a 2 year warranty but I've never heard of them before. Rich, it's leaking from the pump nose behind the pulley. Thanks Mav, the only thing that concerns me now is that I read on an Aussie forum last night that flange for the fan may have a different pcd for the viscous 🙁 The pump that I changed last time had been on the engine 8 years before I changed it and came from the donor Defender engine before that so ...... I think I may have to hold my nose, cry a little bit in a quiet corner and buy a genuine pump and hope that it lasts as long as the original. Unless I still have that old one somewhere in the garage ... Mo Quote Link to comment Share on other sites More sharing options...

It looks not entirely dissimilar to the 'unobtainable' one in a 300tdi timing cover. OK I know it might have non-preferred origins....

ianmayco68 Posted March 29, 2019 Share Posted March 29, 2019 Just found this Mo https://www.ebay.co.uk/itm/LAND-ROVER-DEFENDER-200TDI-WATER-PUMP-OEM-AIRTEX-PROFLO-STC639G-/202189343833 came up on a search might be worth contacting them .

Mo Murphy Posted March 30, 2019 Author Share Posted March 30, 2019 Thanks Ian, I saw those on my searches but, maybe I'm just cynical, they seem to be selling proflo pumps at inflated prices trading on the airtex name. I doubt very much I'd get an airtex pump especially when nobody else seems to have them. Thanks again any way 👍 Mo Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted March 30, 2019 Share Posted March 30, 2019 Yes I did wonder that myself, some of these traders are starting to get clever how they advertise things , seems strange Airtex make them for every other engine but the 200tdi . I’ve got one waiting to be fitted to the 300tdi on the bench . Quote Link to comment Share on other sites More sharing options...
reb78 Posted March 30, 2019 Share Posted March 30, 2019 I have found my 19j pump. We can compare them at some point. Quote Link to comment Share on other sites More sharing options...

western Posted March 31, 2019 Share Posted March 31, 2019 19J & Defender spec 200Tdi both use the same water pump to block gasket, could be a difference in the number of vanes or size of the pipe bores. IIRC my current water pump is a Airtex make, believe I got it from All makes via my local lr parts shop. Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted April 1, 2019 Author Share Posted April 1, 2019 Indeed Ralph. Alas any airtex pumps that were available have gone into hiding without any prior revelation of or clue to their location. So to recap ... For this reason I am seeking quality alternatives. At the moment based on prior experience and recommendation I can really only consider genuine replacement at this moment in time. The previous replacement from Turners which may or may not have been Pro Flo lasted less than 10k miles which in my opinion is nowhere near long enough given that the previous genuine came off a second hand engine, did 40k miles on this engine and hadn't failed when I replaced it ! So any further confirmed leads on the location of an Airtex 200 Tdi water pump would be welcomed 😊 Mo Quote Link to comment Share on other sites More sharing options...
reb78 Posted April 1, 2019 Share Posted April 1, 2019 Have you contacted Turners, Mo? I would think they might have something to comment as they aren't known for providing second rate parts. Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted April 1, 2019 Author Share Posted April 1, 2019 I haven't Rich, it's out of warranty and I'm more inclined to devote my energies to finding a good replacement rather than more of the same. Mo Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted April 1, 2019 Share Posted April 1, 2019 Could be worth a call to Airtex themselves, see if they are willing to confirm whether they still make them or not? 1 Quote Link to comment Share on other sites More sharing options...

Anderzander Posted April 12, 2019 Share Posted April 12, 2019 It’s also possible you just had a bad one ... and the issue isn’t endemic to the brand at all. To help Turners, aside wether they can help you, I’d let them know. They may also say - yours is the only one that’s failed blah blah ... or yes, we found that and have a stock of Airtex...

Mo Murphy Posted April 13, 2019 Author Share Posted April 13, 2019 Thanks chaps. I've bought a Pro flow pump as funds dictated prudence. We'll see how this one gets on. Mo 1 Quote Link to comment Share on other sites More sharing options...
