Hi chap's and chapess's I have searched the tech forum in vain in an effort to solve this problem. So I hope this post is not replicating an issue already raised, so my apologiess in advance if this is the case. The tempreture gauge reading is creeping up when in slow traffic or while idling, Now I know that this is either... 1. Water levels in tank/radiator. 2. Air lock. 3. Blocked radiator. 4. Thermostat. 5. Temp sender The radiator fans attemp to adjust/ cure the overheating. This helps to reduce the problem. I am aware that certain cars which ever make or model have idiosyncrasies, such as explained in detail throghout this site about various models. My Galaxy is the V6 2.3ghia on a T plate 1999. The temp guage needle creeps up to the letter M before the fans kick in, I am worried that it will go higher the longer that I leave it. So to finaly get around to my question Is this a idiosyncratic problem or something major I need to solve, if so where do I start my investigation, finances are an issue so I have my fingers crossed it's not going to cost too much to cure. Regards Nige.
