I have a 84 eagle 10, 6v-92. I have gone the whole route with cleaning and rodding the radiator, new thermostats, waterpump, shroud, checked fan clutch. Still heats to 205 or more if I let it. I have two guages to make sure they are working. Im considering misters and need information as to- do they work and are they worth the trouble of putting on- how many misters and volume of water is needed and ect. |

Running Stock Injectors or did you boost it up? Is the 6V92 a re-engine from a 8V71, or . . .? Sill running the original sized radiator?
Misters are a band aid, suggesting that something is still not up to par in the engine/cooling package. '
If the original, stock, cooling system was undersized, it would be far cheaper to make it a bit bigger than add misters. Otherwise the mfgs would have spent less $$ on radiators and installed misters instead.
But you seem to have touched all the bases which makes me wonder if you've bumped up the heat output of the engine to exceed the original capacity of the cooling system.
Dropping the temp by cooling the water may give you a false sense of security if the real problem is not enough flow Volume , (regardless of the lower coolant inlet temp) - you may have lower temp coolant as it returns to the engine, but that means very little if the total flow is not enough to absorb the heat rejection of the engine. |

Marc- Yes I did have a DD dealer increase injectors to the 330hp from the 265hp orginal. Added a bypass blower and larger turbo to make everything compatable. It heated before this was done and runs cooler now.Orginal radiator, high capacity water pump was installed. How do I check the water flow and can a larger radiator be installed without frame modification? Thanks Roger |

I had Larry Foster at Wilcox Rad in NY make me a rad to fit the original upper and lower tanks to accomodate a larger engine. Great guy to deal with. With todays improvements in rad design and dimpled tubes you can do things like this. He is at 1-800-443-1322 and will ship anywhere. Hope this helps you. Bill |

I had some overheating problems with my 8V92 when I replaced the 6V92. Even with a larger radiator.
I purchased the smallest volume drip misters at a hardware store. Unfortunately I can not remember the size, but I suggest you get the smallest you can find. You can always put in larger ones if needed.
I installed an additional water pump, identical to the one originally installed in the conversion (makes a good spare if needed). I plumbed it into the fresh water tank.
I installed a toggle switch and indicator light on the dash.
I used all plastic drip mister hose. 1/2 inch from the pump to the radiator, and1/4 inch for the misters. You must use small tie wraps to keep the connections together because everything gets so hot.
I installed two rows of three misters each. I turned the misters out at about 45 degrees to give the water a chance to spread out some before it hit the radiator.
I would watch the temperature gauge and turn them on at about 200 degrees. Within just a very short time the temperature would drop down to 180 and I would turn them off.
The amount of water utilized is so minuscule that I could never tell that the water tank was down any.
The climb from Death Valley to Las Vegas in the summer, when the outside temperature is sometimes 110 or more is a real test. I run pedal to the metal in the 2000 rpm or higher range all the time on that and other hard climbs. The genset was also always running and putting a lot of heat into the radiator. Never any problem keeping the temperature down to 200 or below. I had a 40,000 pound coach towing a Tahoe.
I used this system throughout the country for years and thousands of miles without any problem. Never any build up on the radiator like some preach and I think it is a good investment.
I also had two 16 inch electric fans (aftermarket auto, not TD specials) and I had these on a thermostat that came on at 190 degrees. I also had an indicator light that came on when they were on. Although they helped some, they were not a complete answer. They really helped when I was boon docking and running the genset. The genset was plumbed thru the main radiator and the fans would come on every 30 minutes or so and run a few minutes.

You mentioned in your post that you also installed 16 inch fans. Did you install them in addition to the original engine fan? Or did you remove the engine fan?
Thanks. |

In addition to.
They came from Pep Boys and were designed for aftermarket auto applications. They do not even come close to being able to cool the radiator on a hot Texas day (and the wind generally blows hot in Texas), but by coming on at about 190 degrees, they allowed me to maintain 75-80 all the way across the area, as long as I was on relatively level ground. The misters were only required in the mountains. |
