rsweeney 40 Posted September 14, 2014 Report Share Posted September 14, 2014 My golf vr6 has a persisting coolant leak were the cooling system seems to over pressurise and after a good drive there is coolant left around the seam of the header tank. The car doesn't overheat but gets slightly over halfway on the temp guage even though the fans kick in. Any ideas ? Link to post Share on other sites

mrslippery22 2 Posted September 23, 2014 Report Share Posted September 23, 2014 Check hoses, thermostat and housing, also coolant temperature sensor, but you probably just need a new cap like baelieboy said. I use to have that issue with my jetta. Link to post Share on other sites

Lukey. 381 Posted September 23, 2014 Report Share Posted September 23, 2014 get it sniffed to check for exhaust in the coolant, caps are cheap get a new one just so you know its not that either Link to post Share on other sites
MK4motionVR6 41 Posted September 24, 2014 Report Share Posted September 24, 2014 New cap!!! The caps are calibrated to a certain psi & can deteriorate with age... Try a new cap 1st as your cheapest option... If that doesn't work you may have pump on its way out.. Mk4motionVR6 VR6Pete 1 Link to post Share on other sites
