Can someone please tell me how the air driven cooling fan is suppossed to work and how to t-shoot it? I have 95' M35A3 and the fan is driven by the belt, but there is an air line running to the fan hub in the front? The fan never speeds up unless the engine RPM's do. The motor gets up around 240 degrees at times while going slow (no air flow) and it seems the fan clutch should "kick in" and speed up the fan to increase air flow. The tranny cooler needs more airflow as well when pulling, as it overheats the tranny. It seems to me the fan should be kicking in. I traced the airline back to the block where it looks like there is a sensor or a solenoid.. Could I put a manual valve in the line to turn the fan clutch on?? I appreciate any help with this.
There are no other air system issues, just the fan.
Thank you.
