Has anyone installed R&M air scoops on a MCI9 and do you think they help much??? | ||

There has been a discussion of that on the MAK Board. Most replies are, it does not do much help. Suggestions have been to fix the overheating problem first, then go from there. They say it is mostly a band aid, not the correct way to fix the problem. http://www.busconversions.com/bbs/index.php?topic=9582.0 They do look neat though! I own an Eagle, I'm just passing along what I have read. Paul (Message edited by dreamscape on September 25, 2008) | ||

We made a set of Air scoops by slicing a deep stainless steel chafing pan in two and bolting them over the air intakes. Then painting them to match the bus. Deep chafing pans are available at a restaurant supply. They did help the cooling a bit and did not hurt the mpg. As we often travel off the beaten track, we made a window screen to fit inside the radiator door. It catches alot of stuff that would normally lodge in the radiator fins. | ||

Most of the time when you really need the extra cooling you are climbing a long grade and you aren't going all that fast. IMHO, at speeds of less than 25 MPH I doubt they increase the volume of air going through the radiators that much. What is critical is making sure that no voids exist anywhere around the radiator frames. Air will go past and around the radiator much sooner than it will go through the radiator. I increased my air flow measurably by closing off all of the knotholes that allowed air to go around my radiators. High volume squirrel cages would be a better investment. | ||

Since extra cooling is only needed in limited instances, why not install a set of misters. Cheap and I haven't heard of anyone saying that they didn't take care of their problem unless radiator was plugged or restricted or they replaced a 2-71 with a 12-92 without upgrading cooling system. Check the archives on misters. | ||

Regarding getting the rad fan compartment sealed tight... I used the spray can foam around the radiators to seal up the spaces around the back of all those tired rubber seals. Quick, easy, for sure. When the rads need to be pulled, relatively easy to carve it out of there and clean it up for re-application after re-install. Still working on a solution to better sealing for the access door. Body coloured 3M duct tape around the door works really well until then! happy coaching! buswarrior | ||

John, Paul, and BW have the answers, in my opinion. Most of the lack of cooling problem is caused by air going around the radiators, instead of through them. As BW says, seal them up! Look also closely at the blower shaft seals. If air is being pulled by the seals, it sure as heck doesn't go through the radiators! Now, think about the area of the intake of the scoop, versus the area of the radiator it covers. .,.,.,.,.,.,. Done thinking? The intake area of the scoop can't be LESS than the area of the radiator it covers, or it will restrict the air going into that area of the radiator. I have one of the hundred oddities that doesn't use squirrels, BUT, the PO put on misters, and they work. HTH, George (Message edited by George Mc6 on September 28, 2008) | ||

What is in place of the squirrel cage fans? Spray foam is a God send for sealing up the fan compartment! | ||

QM, The MC6s have a large slab radiator on a hinge at the left rear. The two water hoses are connected to swivels, and the six-blade propeller fan is powered by a hydraulic motor on flex hoses. This allows the radiator to swing out almost 90 degrees, making it easy to get to that side of the engine. Temp control is done with a bypass valve, so the fan doesn't run at all under the temp setting. G | ||

Clifford (luvrbus) did a test for Gary LaBombard on his Eagle. Only he was looking for more air into the airbox. Clifford attached yarn to the fins on the intake and drove about 30-40 mph. The yarn stood straight out, signifying a negative pressure area. You might try that on your MCI and see what happens. I would tend to think that engineers when designing these monsters would have thought of that and incorporated that in their design. My 2 cents, Paul | ||

I just noticed that they sell spray cans of AC condenser coil cleaner at HD. Probably not a bad once in a while thing for the radiators too. |
