Cheers for reply. Noticed that my coolant has gone down a bit lately too and for some reason it seems to get up to temperature on the temp gauge more quickly recently. Unless thats just due to the weather. But also noticed that temp gauge can fluctuate slightly sometimes when i turn heaters on. Had temp gauge replaced a few month ago. Dont think the fluctuation is a massive problem though to be honest, its jsut done it a couiple of times lately, but to be fair the car hasnt been running that long so i suppose its bound to have some sort of effect.
