air louvers on engine bay doors.

[TEDDE]

We just got back from Denver Colo. with 105-110 degree heat. My 400 cummmins ran just fine. But why do I not have any louvers on the rear engine doors to let the heat get out. Wow.... our bedroom was almost unbearable with the heat from the engine. My Holiday Rambler has no louvers except on the side. Has anyone added this to their coach and what did you use? I thought of using another set ofdoors or use the louvers out of another set and build them in..but I have never seen a motor home wrecking yard..

Thanks
Ted

I don't know your coach but I believe the louvers are on the side because you have a side rad and that is where the fan blows air out through the rad. I have a rear rad and rear louvers, but even in weather much cooler than what you describe, the bedroom gets pretty warm after a long day on the road, those motors can store a lot of heat. Running the generator and rear air while on the road may help. It will be interesting to see if any other posters have come up with ways to alleviate the problem, extra insulation under the bed or perhaps exta fans in the engine bay that continue to blow after motor is shut off.

I would be afraid that putting louvers on the rear would reduce air flow through the radiator and cause the fan to run all the time. Might reduce your fuel mileage and cause the engine to run hotter. I know Bill Willard put louvers above the rear doors to help keep the closet cool on his Camelot. Maybe he will chime in with some advice.

I'd be careful with any changes that are made to the airflow; I believe the design intent with side radiator coaches is to ensure most of the engine compartment air to flow out through the side radiator. Depending on where your air intake is located, some mods might be possible. Perhaps you can isolate the area behind the closet from the engine compartment below, however if that's done, be sure that you are not blocking any intake air. On my Dynasty, there's a big intake in the rear cap at the roof level. I wouldn't want to divert that air out of it's intended path.

However I've seen some newer Monacos that do not have that roof level intake and have louvers on the upper body rear at the side. If you can ensure you are not blocking any engine airflow (for cooling or air intake) it might be OK to insulate behind the closet walls. Likewise louvers in the rear cap above the door would be OK only if you can be sure that they are not diverting any cooling air intended to escape through the side radiator.

This is the picture of the vent that I installed -- Monaco sent me the part -- It was not a stock item -- Bill Willard

Ted:
Dp a search for Bill Willard's thread "Grill for Rear Cap". Our Camelots (and Sceptors) are well known for the hot bedroom problem prior to 2009. There are a lot of good solutions to investigate in the thread. I need to do the same thing, but it hasn't hit the top of my to do list yet.
Good luck,
Mike

Thanks to all who answered my question. You are correct in saying to be carefull doing anything with airflow as I am sure the engineers at the factory did their homework and made the coach the way it is..I just thought that perhaps someone has done something about the heat in the bedroom. Insulating...I never thought of..I will check that out. Thanks Mike I will do a search of the vent style that Bill did...

Ted -- You must be on the wrong forum -- Engineers? Homework? -- We`re talking about Monaco Coaches here, & none of that applies --Bill Willard

Bill, What year Camelot? is there an intake up top at the roof?... or intake on body side?.. or both?

[William Willard]

Rick -- It`s a 07 Camelot, with a side radiator -- The only way for heat to escape the engine compartment was thru a opening at the top of the compartment door -- I installed a 10" fan inside to help push air thru the grill -- Happycarz (Harry Martin) has this setup, & he also installed a turbo, & manifold blanket -- I usually do the "Monkey See, Monkey Do" thing, but I didn`t install the blankets, & so far the bedroom has been liveable -- The 08 Camelots came out with vents in the compartment door -- Bill Willard

It sound like a lot of the problem happens once you stop moving. The OP that did the fan sound like the right idea you still have a lot of heat after the diesel get turned off to get rid of so a fan in the bay that you run after its off might be a viable idea for cooling the area at least a little bit. I was thinking the fan idea for little c the floor around the dog house gets pretty warm as well.

I have an 08 Camelot and my engine access door didn't come with the vents, screwed again .

Bill, I looked at a picture of an 07 Camelot (Monaco brochure archive) and I can't see an air-scoop at the top (like my Dynasty). Is your engine cooling air coming from somewhere else? On my Dynasty, air that enters that scoop, somehow, gets to the engine compartment to provide cooling air so I'm concerned about reducing cooling air flow to radiator. Bedroom sure gets warm at night after a long days trip in hot weather. I was thinking about insulating... other projects keep taking precedence 'though.

[William Willard]

Rick -- The only cooling comes from the radiator & oil -- Of course the bottom is open to moving air, but the Camelot has no air scoops for cooling -- Never had an engine temperature problem, just heat being trapped in the compartment, causing the bedroom, & both DC, & AC, electrical panels in the closet to be overheated -- Bill Willard
