Engine compartment cooler

[krminyl@...]

Hi Sid,

I echo the same comments from the other guys. I mounted a 12v Hayden
radiator fan just to the right of my batteries, drawing cooler (hopefully) air
through the curb-side louvers, and blowing it across the motor. I hooked it up
to the same wiring as the original squirrel cage fan (bearings went out...and
I heard it was an England-made fan, and about $1000 to replace if you could
find it) which turns on the fan at a set temperature. I also connected it
through a toggle switch easily fingertip accessible through the louver fins,
and
I turn on the fan manually after driving and stopping for the night/day.
Usually 30 minutes or so, and when the air coming out the other side of the
coach is cool, and I flip the switch off.

That turbo gets pretty hot...cooling it down keeps the bedroom cooler, and
hopefully increases the longevity of the engine and it's components. Did it
for under $100.

Pics available to anyone who might 'em.

At the top of my engine is a squirel cage fan that directs air over
the engine. It does not seem to work. Anybody know how it works.
Looks like there is a sensor wire running to the engine. Is it useful
or should I just forget about it?

BTW for those who remember my alternator problem, all seems to be
working well. The volt and amp meter are a little flaky, but when I
test everything it is ok. Thanks for the help.

Sid: Take it off and forget it. newer coach's don't have them. It was
strickly a fan to keep the bedroom from absorbing the heat when the
engine was turned off and started to heat soak things. I checked years
ago on my 84 1/2 when mine went out. Bluebird wanted about $800.00 at
that time to replace the little 12v motor (made in germany and not
stocked)..they said to forget it and I did. No problem. The best way to
save from heat soaking is after a long hot run when you pull in for the
day is to just open up the engine compartment doors an hour.... Bob

Hi Sid,
That fan is thermostatically controlled and was used to vent the hot
air from above the engine compartment heat shield to prevent excess
heat in the bedroom. The one in my '90 went bad (bearings) and a
replacement, which was available a few years ago, cost over $1000.00.
I fabricated a duct the size of the old fan and end fed it through a
piece of flexible defroster duct from a 12 VDC bilge blower mounted
above the batteries. Worked great and total cost was less than $75.00.

Hi Sid,
Before you scrap the fan, check it out good and make sure it really is
bad. On my 89PT40 I didn't think it worked until one day I noticed an
almost hidden toggle switch on the side of the fan. I had just pulled
into a campground and opened the hatch to let it cool down when I
happened to see the switch. I flipped it and the fan came on. Yours
could be something that simple too.
