Thermostate Setting for Failing Squarrel Fan

[Curt Sprenger]

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,

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.

Jay,

Thank you for the information.

Shane, I'd like those pictures, and any pointers that you remember about
adding the fan...fan model number, mounting, etc.

Hi Curt,

My thermostat is mounted in the ceiling of the engine compartment
just above the alternator on my 6V92. 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.

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.

Hi

I'm glad someone found that snap disc. I found years ago on my 86PT40. It is a
great
part to use for any external engine fan controller.

Hi All,

I will get some photos of the installation tonight after work and
post them/email them to any one interested. 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,
Yes, that is the Grainger number I used.

Can someone explain how to run the wires for this set up?

Scott,
Use the 12V + wire going to the squirrel cage fan as a "trigger" for
a Bosch style relay. 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.
