My 87 300d with 603 eng has a bad fan clutch, it just spins and spins after shut down when its hot even at 100deg eng temp. I have the aux fan running strait in the mean time but the clutch is over $200 new which I think is the only long time solution as opposed to injecting it with toyota fluid. I went to Strauss the other day and all the fan clutches they had were between $30-$40 while my 603 clutch is over $200 which is rediculous. I was wondering if is possible to swap a fan from another car, MB or otherwise, or maybe even converting to an electric main fan altogether using a fan from a pull-it-yourself yard and the relay and sensor from the same car(many of them even have 2 speeds) but I would buy the relay new and change the bearings on the new (old) fan. I dont see what's so special about these 603 fan clutch that makes them so expensive, its really disheartening having to pay so much for a part that is at least 100% cheaper on must every other car which is what makes me think of doing this swap. Has anybody else try something like this?
