Hi all! I'm curious what the air plenum flaps do, and I'm hoping someone can educate me, please. I'm referring to the parts mentioned in this thread:
http://914world.com/bbs2/index.php?showtopic=349044 My guess is that they prevent water and rocks and other stuff from getting to the air-cooled fan...am I correct? Would missing these flaps hurt engine cooling? (I can't see how, but I might be missing some part of the picture) Also, what makes the flaps open? Just the low air pressure on the intake side of the fan? Thanks for your help! |

To further clarify...they're simple doors that close to force the electric blower fan airflow into the heat exchangers instead of bleeding into the fan housing (an easier route, especially at low RPMs.)
