So the fan on my D1 failed. Close examination shows material fatigue around an air bubble inside the plastic.
So I went looking for a temporary fan to run until either replacing the broken one or adding electric fans.
Since I live in the boonies (SE AZ about 5 miles from Mexico) the closest Rover anything is my truck. Dealer is 90 miles away. So I took the broken fan to the local salvage yard and came away with a clutch and fan from an S10. The S10 fan is used on many 4.3l V6 GM vehicles. It is an 11 blade fan as well. Dorman makes a replacement 620-602 and VDO - Cooling Fan Blade - Part # FA70377. About $40 new (saw one for $24 on Summit Racing), $15 or so at the salvage yard.
It uses the same fan clutch referenced in other threads. The fan is larger and a bit heavier. It is plain glass reinforced nylon. So I popped the clips off the shroud and pulled that out then installed the S10 clutch and fan. Initial impression is that is moves more air at lower RPM and seems to freewheel easily as the RPMs build. That seems good so there isn't a huge difference in load on the pump bearings. Once the clutch actuates the airflow is noticeably more than the OEM fan but not much more noise.
I suppose that since a replacement can be had for $30 these days it is possible to keep one on hand for a trail fix but if you find yourself without a spare and surrounded by GM parts it would make a nice temporary repair.
