Lee.j 0 Posted February 14, 2014 Author Report Share Posted February 14, 2014 well today i decided im taking it off the road tommorow and re-insured the polo until sorted as i now have steam comming outta the dash when its at standstill after being run for a bit anyway im going to crack on with it sunday and take my time i think i will document the process with plenty pictures lol just a quick question on these vr6's how do i go about bleeding the system once the matrix has been done as the haynes manual doesnt cover the vr6 engine is there any bleed screws on any of the coolant pipes ? or do it just let it run with the expansion cap off Link to post Share on other sites
Ickyketseddie 89 Posted February 14, 2014 Report Share Posted February 14, 2014 Run with the expansion cap off as far as I'm aware unless anyone else knows different? Sent from my iPad using Tapatalk Jakeyb 1 Link to post Share on other sites
Lukey. 381 Posted February 14, 2014 Report Share Posted February 14, 2014 Yep it's self bleed, with varying degrees of success depending on how the planets have aligned in space, as far as I can see cos it has nothing to do with how you do it. Link to post Share on other sites
VR6Pete 1,455 Posted February 14, 2014 Report Share Posted February 14, 2014 My corrado was a nightmare to bleed up, kept boiling over, eventually the air lock came out, did the old filling up the pipes in the heater matrix until water came out other end trick, heaters on etc.... and after about 3 attempts was ok Link to post Share on other sites
