t5kyo 0 Posted May 24, 2010 Report Share Posted May 24, 2010 Hiya guys, i have recently been having problems with my coolant system. It has been over-pressurizing to the extent that its constantly letting out steam and anti freeze from the release hole in the header tank. I also have rock hard water pipes too. The aux water pump is starting to make some funny noises, and it seems like it struggling to start when i thy and turn the key. Does this indicate a HG failiure, or a water pump problem? If its the water pump, what am i meant to be looking for?!! Cheers people! Link to post Share on other sites
Sheeldzy 1 Posted May 24, 2010 Report Share Posted May 24, 2010 Head gasket probably, get it sniff tested and done asap. My VR6 had this happen when my friend had it last year. His header tank cap then failed and the header tank split at the seam. We rebuilt the head in his Mam's kitchen while she was caravaning. Valve grinding paste all over the curtains, what an odd summer. Link to post Share on other sites

Sheeldzy 1 Posted May 24, 2010 Report Share Posted May 24, 2010 Sniff test first to confirm though, not sure I made that 100% clear Link to post Share on other sites
thegoth 5 Posted May 25, 2010 Report Share Posted May 25, 2010 what's your dash water temp showing? Link to post Share on other sites
t5kyo 0 Posted May 25, 2010 Author Report Share Posted May 25, 2010 what's your dash water temp showing?Hiya, its showing normal running temps, it fluctuates between 72 on a run, and 88 when standing in traffic. The fans come on about 88 then it declines to around 80 whilst standing. if its the water pump, how would i tell? and where is the main pump situated? Cheers! Link to post Share on other sites
craggsy 91 Posted May 25, 2010 Report Share Posted May 25, 2010 That's oil on the mfa. Water is on dash to right. Should sit at 90 all the time Link to post Share on other sites

Cheers![/quote']In most caes if the water pump fails the water temp gets very hot as it doesn't get pumped through the rad. similairly if the the thermostat gets stuck shut. As an aside if the water temp is fluctuating the thermostat could be stuck open - or removed.main water pump is powered by the belt on the air filter end of the engine.I would agree with the sniff test recomendation.

t5kyo 0 Posted May 26, 2010 Author Report Share Posted May 26, 2010 my worse fears are confirmed..... my HG is on its way out. its allowing exhaust gases into the water system, which is pressurizing the whole thing, which would explain the rock hard pipes and topping up of antifreeze. Oh well, guess im gonna part with the VR and get something else, so it'll be up for spares or repairs with pics to follow.....the irony is, ive just had a new 6month tax disc for it!
