Thermostate Setting for Failing Squarrel Fan - Curt Sprenger - 08-13-2007 15:58 Several of us have recently posted about the ratteling or non working fan that is mounted in the upper rear area of the engine compartment. Does anyone know the thermostat degree setting for that fan? Anyone know where that thermostate is located? My thought at this time is to control the add-in Hayden fans to run off the same controls. -- Curt Sprenger 1987 PT38 8V92 "MacAttack Racing" Anaheim Hills, CA Thermostate Setting for Failing Squarrel Fan - Jay Darst - 08-14-2007 03:20 Curt, I found a Snap-Disc type thermostat buried in the ceiling of the engine compartment. It is positioned so that it would read the temp DIRECTLY below the bed, in the engine compartment. There is a piece of sheet metal that is spaced from the engine compartment ceiling. The SNAP-DISC thermostat is between the 2 pieces of sheet metal. Shane Fideli used the wires that powered the noisey old long skinny fan to trigger a relay that powered an automotive type fan fastened to the inside of the curb side engine compartment louvers at the top. He did a nice job on the installation. I wish I would have looked a little closer at it. I plan to install a cooling fan the same way. Shane, if you would send me some close-up pictures of the mounting procedure for that fan, I would appreciate it much.

It is about the size of a small bottle cap. I used it, in conjuction with a bosch relay, to power a Hayden fan that cools the engine compartment. I used the largest fan that I could find at Advanced Auto parts and mounted the fan behind the grill that provides access to the curbside of the engine compartment. Originally, I had set my fan to expel the hot air and work in tandem with the large engine fan to pass air through the compartment. Once parked, however, I have achieved better results by drawing cool, outside air into the engine compartment, expelling it through the radiator. I usually just reverse the wires on the fan, causing it to run backwards. This would cool the compartment so fast, that the relay would shut it off, so I also installed a SPDT switch to override the thermostat and leave the fan on. I may eventually install at DPDT switch to reverse the polarity without having to pull the wires off the fan. This setup has worked fine for about 12K miles and the fan does not seem to mind running in reverse.

Truitt - 08-14-2007 04:53 Curt, I took the old motor out and took to Grainger could not get an exact match but was able to do a little shade tree modification to make it fit. I spliced into the old wiring so it now works off the old temp control. I used the male/female connector in case I needed to remove the motor.

I found years ago on my 86PT40. It is a great part to use for any external engine fan controller.

If you were able to repair the squirrel cage AND have a Hayden fan, the bedroom would stay REALLY cool. Howard- do you recall the part # on the Grainger fan that you installed on the squirrel cage? Was it a Dayton Model #2M197 ?? -Shane --- In WanderlodgeForum@yahoogroups.com, "Jay Darst" wrote: > > Curt, > > I found a Snap-Disc type thermostat buried in the ceiling of the > engine compartment.

You will want to supply the main voltage to the fan directly from a 12V source in your charger/Rediline compartment. The fan will draw better than 12 amps, which would burn out the thermostat contacts over time if you don't use the relay. Be sure to also use 10 or 12 ga. wire for the fan. The trigger wire from the squirrel cage can be lighter size since it does not carry much of a load. I located the Bosch relay in the charger compartment and ran the wires from the squirrel cage and to the fan through a 1/2" hole in the compartment wall. Make sure to use a grommet to prevent chafing and try to enclose all of the wires in wire loom or some sort of conduit. If you are not familiar with how to wire the relay, this is a great project for learning- there are numerous links floating around the web with instructions. Also be sure to install a 20 A fuse between the 12V source and the relay.
