*Glenn* 855 Report post Posted September 4, 2008 Dont drive it anymore. Get it towed to a repairer and have it checked. Might only be a thermostat or the water pump impellor may be broken. Quote Share this post Link to post Share on other sites

Ill drop past with another viscous fan for you to try tonight, see if that sorts it out, if it doesn't then we'll look at the thermostat. I'm still puzzled as to the water flow from your old water pump, usually the metal impellers don't give many problems, but there was definitely a lack of flow through the system. I hate that feeling driving along, especially in heavy traffic eyes glued to the temp gauge. Quote Share this post Link to post Share on other sites

Mark 178 Report post Posted September 17, 2008 If the car is getting hot while sitting stationary and then cooling down while driving it will be the Auxillary fan. Check the fuse... it could be blown. Quote Share this post Link to post Share on other sites
