Side Radiator fan running fast all the time: Fixed

Since I purchased a 1999 Windsor 5 years ago I have noticed that the side radiator fan was running fast all the time.. I finally fixed it with help from Scott of source enginerring . Turns out that the hydralic lines at the thermostatic wax valve where hooked up backwards.. Replaced wax valve swapped lines and MPG and power have improved noticably.. Fan now runs slower a low temperatures ( start up etc. ) No more dust storm behind me when on gravel.. This could of been hooked up backward from day 1 at the factory..

Hope this may help others.. James

This alpine post helped as well ..

On my wax valve there is a painted dot on one of the fittings and a painted dot on one of the lines so I am assuming since they match that it is hooked up correctly. My fan does not roar when cold but sure does when hot. How did you know which line went to what fitting on the wax valve?

I too would like to know how to tell which line goes where. We live 1/4 mile from the highway on gravel road. By the time we reach the highway, the dust storm from the radiator fan has messed up the back of the coach and the toad. But, the engine never overheats, so I have been procrastinating about doing anything about it.

Jim, I have a 96....I will snap a pic and email for verification we have the same setup....then if we do, I will check where each hose goes from the controller.
At idle you can't feel any air flow through my grille. I have heard it run the fan at speed maybe 3 times, through the 95+ summer heat...and there is NO mistaking it is locked at that time due to the roar it makes

Not sure I have the same setup as my rig is a 93 navigator, but one day after work I noticed that the fan was running by itself on a 105 degree day!! I figured the relay had gone bad, I replaced it but the fan kept running, I finally had to remove the blue spade fuse to make it stop.

Any thoughts on this one?

Different type fan. The later all use a hydraulic motor vice an electric motor. On yours it sounds like the thermostat has gone bad. I would think that is screwed into the tank on the radiator. Normally those type thermostatic switches are set to turn on in the 170-180 degree area.

See the system schematic in post#19 of the OP's linked thread in initial post above for hydraulic plumbing layout.

Valve is made up of the sensor section that goes into the radiator coolant flow, and the valve section that sticks out & has the ports. Valve section can be rotated vs the sensor section to direct the ports as needed for the application. Input port is on the outside of the assembly, away from the hex head that tightens valve to the coolant manifold. Output port is next to the hex head, closest to the manifold.

Valve has an o-ring seat to the manifold, so if yours is leaking at the hex/manifold, try changing the o-ring. The wax wears out over time.
