Hi Terry Good to hear you had a decent break over xmas.. And glad to see you back and active here..hehe I have some more information about this thread.. I checked the thermostat today and sure enough it isn't fully closing. I had another one here the same so i tested it and it was fine so I chucked it in. I also set the Webers up a bit better,,, Then go for a run on the motorway and sure enough the temp DIDN"T go up..just stayed on the stop ie 0 ... Come off the motorway and sit at traffic lights and straight away the temp starts to go up and sits steady at "E",, As soon as i go back on the motorway the temp drops down to zero again. So I get off the motorway and by the time I'm in my driveway the gauge is up to "E" again.. So 1. The thermostat is tested and works @ 88 degrees. 2. The gauge seems to be ok 3 The engine feels a bit different ie down on power and unhappy 4. The engine is hot to the touch after such thrashing but the radiator is just warm I can see how a thermostat would cop a hiding in these circs and the one i tossed is less than 12mths old. Should i just try a test with half the radiator blocked off? Not my preferred option but easy to test.. Or remove the fan blades (tempting but harder) If the temp became more 'normal' you would have to say that its 'over radiatored' wouldn't u? The big question is what effect is this gonna have in a sprint situation where often getting enough heat into engines, brakes and tyres is the major problem? Sorry for all the questions and thanks in advance. cheers Mick
