    Hello members
    I have a 55 plate clk 270 cdi, last night on my way home from work I got stuck in a traffic jam & it was a crawl home for about a mile during which the temp gauge climbed up till it went right to the top, this has happened a couple of times before but when I am driving round the temp gauge sits around half way but will on the odd time creep up to around the 3/4 mark which it never used to do before. I am thinking that the fan is not cutting in so maybe there is a fan stat that may not be working, can anybody tell me how to check this & where & what kind of job changing the fan stat is if it is that the is the problem.
