    Hi guys, So I've been trying to diagnose a rattling in my engine during idle for quite a while, and I had managed to determine that it was the fan by removing the fan belt and running the engine for a few seconds. (Noise disappeared!) Today I took the fan off and noticed that there was some...

    Hello, just wondering if anyone has an exploded diagram of the alternator/backing plate/fan hub assembly, as I want to make sure I have all the washers and bits and bobs in the right order (late fan housing with wider fan)

    hi im just curious has anyone done a conversion from mechanical fan to electric on the fan housing, as apparently you can get better power output as the power is being reduced by the torque required for the pulley being less. just wondering if anyone has and seen power increase

    I'm thinking of getting one to help with the clearance of my carbs plus i like the look of them, a couple of things though... do you normally just fit these or do you put in the heating flaps first? if you run it without flaps do you have a problem with heating up the engine ie causing more...

    I have not had a chance to investigate this yet. There was a kind of knocking noise on tick over which I have isolated to the fan rocking on the alternator shaft. The nut is not loose but the fan can rotate either way slightly on the shaft. Are they located on a keyway? It seems as though...
