Very Hot Hood On Deutz Allis 616------------------

Recommended Posts

I had the previous post about the very hot hood and maybe found the problem--- possible wrong spark plugs??? missing foam air shield that looks like it was glued onto the top forward side of the engine shroud-- it went from the top of the engine shroud to the inderside of the hood-- would that make a difference??? any comments???

Hi, Yes! This foam is to prevent the cooling fan from pulling hot air from the muffler area and causing the engine to over heat. Note there slots in the hood near the cowl. These are to let cool air in to the engine and reduce the need to pull air in from under the edge of the hood where the air will be hotter. Very good observation. Most people don't understand the importance of complete cooling systems and air cooled engines. Things like this foam and the slots are done to keep the head and oil temperatures in spec to insure long engine life. They are usually done because of high numbers when the application temp testing is done. Al Eden
