Ive just noticed that water cooled power steering reservoirs are available for cosworths, just wondered how effective they are, I was intending to fit either one of the original air-cooled coolers or a mocal style cooler behind the foglight grill but I can't find one small enough to fit nicely behind the grill so was wondering if the water cooled reservoir would be good enough to use on it's own without any sort of air cooled cooler.
