Newbie Issues...Engine Bay Cool Down Methods

[Leroy Eckert]

Ron:
Question please on the fans.
Did you use two relays, a single relay or run the power through the switch. I
presume the fans are 16" Hayden or equivalent which draw about 15 amps each.
Thanks

A few of us here in Texas have installed 12V electric radiator fans on
the passenger side of the engine compartment, blowing back over the
engine and through the radiator to aid in the cooldown of that area.
It really helps a lot. I installed a switch next to the fan that I
turn on when I shut the engine off. I let it run for 15 to 30 minutes
after shutdown.

You should have a 5 inch X about 18 inch flex coupling that goes between your
turbo and the muffler and is directly under the floor rear of the bedroom or
closet.
Be certain that is not leaking exhaust,it is an ideal place for rust to start
and of course leak exhaust. Hot and dangerous.

Thanks Fred and Jeanne!
Everything in the engine bay seems fine...just hot. I'm going to try
opening the main hatch as well as running the roof vent. Part of my
problem was also that there was a short in the DeSoto 30A line. It
kept tripping the breaker even with just the 'fridge and one A/C
going. We woke up at 2AM with the interior warmer than then
outside. I fired up the genset and all was well again.

Thanks for your help! I'll keep an eye on that flexline..

Out here in the Seattle area, after a run, I turn on the fan override
and leave it on till shutdown.
Also open the engine hatch for a couple of hours.
Since we have a Select Comfort air bed, it really blows up with the hot
air coming up. I try to remember to let air out before we start for the
day.

Run the fan on switch from the cockpit to over cool the engine prior
to shut down. The engine will rise in temp after shut down befor it
starts to cool at rest. I fear any attempt to reinsulate to correct
the problem, may prove a fire danger.

Being the shake down cruise, The heat may be more alarming then
actualy uncomfortable. I was concerned at first, now I defrost in the
bedroom closet.

Bob,
Thanks for the advice. I noticed that the fan override switch on my
coach only works when the engine is running. It would be nice if
those fans worked after engine shut down. That would vent the heat
quickly...

Thanks again!

I don't know about the '00 coach, but for most (all?) of us, that fan is
hydraulic, so it can't run with the engine off.

That explains it. I'll have to remember to switch it on for a while
prior shut down. I can't tell you how much we appreciate everyone's
knowledge and patience. We are very new to this..

On another subject, I noticed your response came via satellite. We
bought the coach specifically to explore the West next summer for
three months. I would like to stay in contact with my office during
the trip and I need to explore ways of doing so, either satellite or
broadband cell. When you get a moment, can you let me know how your
satellite connection works? I know the dish on my coach is in-
motion and the receiver is DirectTV but I haven't tried either one
yet. Thank you!

Allen,

I once had a problem with that piece of pipe with the flex coupling.
It was cracked right at the flange where the pipe clamped to the
output of the turbo. You couldn't see the crack and there was no
noticeable exhaust escape at idle speed, but at highway RPM the
pressure would separate the pipe at the crack! The first symptom I
noticed was a noticeable drop in turbo boost pressure. The engine
compartment got so hot that the plastic placard on the Front/Rear
ignition switchover panel started turning up at the corners!
