Title: Volumex water pump Post by: mtulloch on July 02, 2014, 08:17:37 PM Are the VX coolant water pumps identical to the other Betas as mine has a noisey bearing and needs replaced?
Found this and it says that all are the same but I seem to remember somewhere that the VX pumps are uprated. http://www.ebay.co.uk/itm/291180897664?ssPageName=STRK:MESINDXX:IT&_trksid=p3984.m1436.l2649 (http://www.ebay.co.uk/itm/291180897664?ssPageName=STRK:MESINDXX:IT&_trksid=p3984.m1436.l2649) Also, are the bolts which hold the pulley on reverse threaded as I cannot shift them? Thanks. Title: Re: Volumex water pump Post by: rossocorsa on July 02, 2014, 11:21:05 PM Pump has slightly deeper impeller, bolts are normal. You need graf pump pa168 or similar

Title: Re: Volumex water pump Post by: andybeta on July 04, 2014, 11:19:00 PM Go for a Monte water pump. Don't know why but this is what GC recommends. Eric may well be able to say why or even disagree.
Title: Re: Volumex water pump Post by: rossocorsa on July 04, 2014, 11:21:29 PM The graf pump is Monte spec
Title: Re: Volumex water pump Post by: lukasdeopalenica on July 28, 2016, 06:00:58 PM I know it is old thread but maybe it will be helpful for someone in the future. Now I had the chance to directly compare the two types of pumps. The only difference as it was said is the impeller height - 16mm for VX vs. 13mm for standard engines. Other details are exactly the same. That means a VX pump should improve cooling efficiency of standard engines, e.g. of mine 8)
