Plug Proof Outside Radiator

Plug Proof outside radiator ENGINES Engines 15-4-10 Israeli farmer Doron Yoffe, who's an avid FARM SHOW reader and innovator, says he's come up with a way to keep engines from overheating that might be of interest to many North American readers. "In the Middle East we have long hot summers when it's 90? or more for 6 months. That creates engine problems, especially when radiators plug up with straw or other debris. Since more vehicles now come equipped with electric fans rather than the traditional V-belt drive, I realized that the radiator location doesn't have to be down by the engine and could just as well be positioned out-side the engine compartment for easier access. "I decided to modify my Manitou 420 telescopic 80-hp. loader that's powered by a Ford engine. The machine had been a problem because the radiator was `buried' where I couldn't easily clean it out, check coolant level or spot leaks and the radiator itself wasn't big enough for our climate. "The modification was not expensive. I bought a new, bigger radiator and mounted it on the left rear fender. An electric blower, which I bought for $50, mounts behind the radiator. A protective metal mesh screen mounts in front of it. A radiator shop modified the inlet and out-let nipples on the new radiator and in-stalled a third threaded inlet for the electric fan thermostat. "It was successful. Even on the hottest days, the engine doesn't overheat. Blower kicks on and off as needed. One problem is that electric blowers have limitations in size. One solution might be to install a hydraulic motor although it might in-crease conversion price of about 6 times."
