Another Mister Question

[garhawk]

Hi Lin,

If you look back in the posts to, I believe around April, you will find a good discussion concerning misters.  I installed a system on my 1989 Model 20 Eagle with a DD Series 60. 

The house water system was used, as the bus has 160 gallons capacity.  There's little chance of running out while using the mister.

I drilled the smallest holes I could get the drill motor chuck to hold
(1.25mm) and, they work well.  However, I believe you'll find there is not much science to this endeavor.  My theory was, and is, that drilling the holes close together will get you a 'wall effect' of water.  Close enough that no gaps are in the pattern and far enough apart that no
overlap occurs.

I know Clifford and others refer to this cooling method as a bandaid and, they're probably correct in that it doesn't heal the sore of overheating.  However, I can attest to the fact that it works to keep temperatures in check when needed.

My 5C came with rad scoops, about 3"  X 3" X the hight of the rad grill. I didn't like the look of them and removed them: did not make any difference in running temperature. As BW mentioned, I should do like Fred Hobe and experiment with bigger  ones.

As far as road speed for scoops to work, a few years ago before I put a turbo on the 4-71 in the Courier, I built a sheet metal scoop for the air intake and it was effective at surprisingly low speed, like 20 mph IIRC. So I think well designed big rad scoops would work going up a hill at lower speeds. I should rivet big ugly sheet metal ones and experiment...

lvmci. follow your coolant lines out of the radiators, they mix together at the bottom before being sucked/pushed back into the engine.

No problem, as long each side is contributing something significant to the cooling process...

happy coaching!

Gary, your small holes is the way to go I have removed radatiors people have kinda flooded over the years it may not hurt the MCI but I replaced one in a older Prevost the thing looked sand blasted the big fan sucking water in cost him 3000 for a new one
