I have a question. I have the hydraulic pump design for running the radiator fan. There is an air cylinder attached to the pump which has a regulator set for 65psi. It looks like it is supposed to push on the pump and create belt tension from the pulley. It has a shutoff valve also. How do I test if this is working? If I switch the shutoff, the cylinder does not depress. I'm wondering if the tension on the belt is enough.... |

I checked the air cylinder and it is working correctly.
On a side note, I disconnected the two lines at the thermocouple and connected them together. I assumed since I was bypassing the thermocouple, I would have full fan speed. It didn't make much of a difference, meaning I was not getting blown away by the fan. Should this concern me? It also looks like the fan rotation and the fins would pull air into the engine bay. Sound correct? |

It's actually the reverse. As coolant temp increases, valve closes increasing pressure... |
