Continueing the discussion on antifreeze and water wetter. I have a turbo on my sports car and it is prone to getting hot, the remedy during the summer, is to refill the radiator with a smaller dilution of antifreeze. Antifreeze is not a good agent for heat transference, this is well documented. Water wetter is also used in high performance cars, not just old ones. During my trips to Italy, I found that using water wetter reduced the engine temperatures by 15 degrees when driving and the turbo on full song.

Make sure you put the undertray back on before the winter or else your alternator and aircon compressor bearings will suffer.

The plod boys use a big hefty metal one......like the one on my Estate (must post a pic!)

I think its metal to stop them damaging the sump when they run over car thieves...
