broken viscous fan and now RADIATOR! i did think it was odd that the viscous fan was always spinning, last night though there was some cluncking and rattling up-front so pulled over to look... the viscous fan had shattered or come off its mounting and shattered on the other pulleys- mangling the radiator fins and leaving water pi55ing out of the rad!!! So... is it possible to bodge the leaking radiator with some gum/paste/epoxy/product until i can sort a replacement? why is there a viscous fan anyway - other cars i've had just had the electric one? could i run the car without this extrs fan? Haynes says the viscous coupling should spin freely til 75 degrees, then lock-up to spin the fan - mine was ALWAYS spinning - a drain on power really as there was no need for it to be spinning - we don't live in a desert full of trafficjams? seriously, why's it even there?
