Whilst in a queue to get my car washed last saturday i looked down to notice my cars temperature gauage had gone about 3/4 of the way up. It has never been above 1/2 before even after hours of driving. As soon as i was moving again it came back to 1/2 way. I guess that the rad fans were not kicking in but wanted to check at what point they should. All the other cars i've ever owned never let the temp gauage get above 1/2. Also, is there away to check the fans work, can i earth the sensor or something similar so at least i can at least narrow down the problem.
