ojs1306 0 Posted March 6, 2009 Report Share Posted March 6, 2009 Hi Wonder anyone has any ideas on this issue:97 R VR6 2.8, on tickover the car runs at a normal temp of 90 - (Half way on the gauge)On a recent long run on the motorway the gauge moved up to between 90 and 100.Checked oil and water - both fine and no usage..... only goes past the 90 mark when engine is under lots of load.Wont go beyond 90 on tickovercould this be due to themostat? or waterpump Link to post Share on other sites
thegoth 5 Posted March 6, 2009 Report Share Posted March 6, 2009 not stat to my mind. stuck shut would cause it to overheat completly and blow water out of the header tank. stuck open the temp would sit at ~70 on tickover.so main water pump or maybe clogged radiator. disconnect the fan supply and check to see if entire area gets hot.

Charged VR 0 Posted March 6, 2009 Report Share Posted March 6, 2009 Id second that, Take the water pump out and check the fins, When i did my rebuild my old pump only had 3 fins leftGet it sorted soon though so it doesnt cause any major problems!! Link to post Share on other sites
