pizza boy Posted February 11, 2004 Share Posted February 11, 2004 My m8 is getting a wierd overheating problem in his rev2 Turbo. Its very tempremental because sometimes it will be fine and other times the temp gauge will shoot up. It has occured ever since he changed the coolant himself and with a m8. He has since got Toyota to check it and they have told him its his head gasket.He has also had the coolant replaced from a proper mechanic to straighten any he screw ups he woulda made when he carried out the job himself. The mechs told him they dont know what it could be. He has also changed the water pump to..no effect same problem. His heaters also blast extremely hot air out even when the temp gauge is stable. Any1 have an idea what might be causing this? Quote Link to comment Share on other sites More sharing options...
mattmr2 Posted February 11, 2004 Share Posted February 11, 2004 The coolent system may need purging, which forces all the crap out coolent system, you can get a quite build up of crap in the pipes if you don't use glycol based coolent. It might also be the thermostat playing up, but i don't know much about that......hope this helps in some way.matt Quote Link to comment Share on other sites More sharing options...
