Sweet Cream 8 Posted July 20, 2017 Hi everyone, Pulled my xc off the road to do a few maintenance things and also replaced the water pump. Mine has aircon and was running a three belt v-belt pulley with a solid aluminium spacer against the fan. I pulled the old one off and put it in the trash box, but didn't throw it out. I guess out of sight, out of mind. I have to have two manuals for the xc, one for the body and running gear and the other for the xf engine so when I ordered a new xf water pump I used the manual. When the pump arrived I checked it off against the xf manual. All correct. Now comes a lesson in tardiness - I fitted the new pump and forgot to physically check the new one against the old one before I did. Wouldn't you know it, the pulley fittings are different and my fan won't fit. Center hole in my fan is far too small and bolt holes closer together. I assume that the mechanic who put my engine together and into the xc must have used an xc water pump which has a small hole in the aluminium spacer and fan. The standard xf has a large threaded shaft. The question is, would there be any problems with getting an xf fan and bits from somewhere and lining everything up with the aircon, alternator and crank pulleys? or should I just simplify it by ordering another xc water pump with the holes that will match my own fan and spacer? Any advice muchly appreciated. Heath 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites

deankxf 20,288 Posted July 20, 2017 i'd buy an XC pump and have it running perfect in 20mins.. otherwise, you could fit a thermo fan and free up some horse power that probably won't be noticable.. the clutch fan should be more efficient, not sure if you have the space for one? then you have the pulley issue? will they just line up, i would guess yes. 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites
CHESTNUTXE 7,310 Posted July 20, 2017 i have a similar delema i want to use the 86da plastic xf clutch fan on my crossy build but am i sacrificing hp ? i also have the xe metal 7 blade clutch fan but that is much heavier than the xf one. Share this post Link to post Share on other sites

Hi deankdx, I'm tempted to go the XC pump way. HP not an issue. Going to fit a thermo fan end of year so I can address other issues then. My XC is farm and music transport vehicle so time is important at the moment. Thanks for input. Cheers 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites

gerg 10,871 Posted July 21, 2017 Yeah NPT sounds like it, BSP will fit but is one thread out so in that case just reach for a longer spanner Sent from my CPH1607 using Tapatalk Share this post Link to post Share on other sites

LJDB 103 Posted July 25, 2017 Don't forget the actual function of the fan. You will lose more than HP if you cook it. Fixed fan never gave any cooling issues and hassle free motoring. Share this post Link to post Share on other sites

Hi Dean, Correct water pump here yesterday and fan fitted nicely. Got to get my EP mixed and up on iTunes by September, so might address electric fan later in the year when I have more minutes. My XC engine bay has nice elbow room, so a lot of options open to me. Cheers, Share this post Link to post Share on other sites
