That #$%[censored]%^&* money pit (AKA '74 164E) did it again. It started with an innocent chirping, and 30 miles later it put it's fan through the radiator. You can imagine what a 6-bladed metal fan spinning at 3200 rpm does to a radiator. Thank god for free towing from the ANWB.

Yup, you guessed it, the viscous coupling disintegrated. As this is a known weakness I'ld looked at some at the dutch Volvo meet, with the idea of buying a couple of spares. They were all bad. No luck.

Would the viscous fan unit from a 240 (newer, ie still available new from Volvo or much newer from the pick'n'pull) be likely to fit?

Alternatively, what is the collective wisdom on welding the hub to the rotor on an old unit and just using it as a fixed fan (apart from loosing a few horsepower and slightly more noise)?

Or I could just go for a kenlowe or similar electric fan, although they tend to be quite expensive (said he, without having priced a new viscous coupling) or possibly dodgy if from the pick'n'pull.

Thanks,

Bram
