Hi Guys,

How easy is the coolant sensor to fit? Where can I get one for a 95WRX?

I have fault code 21 and hopefully this will be fixed by the above. However I have to add half litre of water to the resevoir on the right hand side of the engine (not the header tank) every couple of weeks. There is no deposits in the oil or rust on the plugs and I can't find any sign of leaks any where! Any ideas anyone??

Thanks
Mark
