The German thermostats and ours are fail safe, meaning that if they fail, they SHOULD fail in the full open position, giving you maximum cooling. With a fresh blasting and powdercoat, you should be fine for many years to come.Ĭan the thermostat get stuck closed, causing the engine to overheat? However, I have rebuilt 100's of thermostat flaps and Nothing is impossible, so yes, they could get rusted closed or hung up in the closed position, which would result in an overheated engine. So, if you are notĬoncerned about those things, you don't need thermostat flaps.Ĭan the flaps get stuck closed, causing the engine to overheat? This means that all of those engines have lower fuel economy (less MPG), more engine wear, and resulting shorter engine life. However, all of those engines are running too cold at startup. ![]() Many air cooled VW's are running all over the world, in all sorts of temperatures and conditions with the flaps missing. But NO, you are not required to run the thermostat flaps. Everyone thinks they are meant to keep the engine cool, when it really is meant to heat it up quickly. That temperature. This is the #1 misconception about the thermostat and flaps system. The flaps are there to get the engine heated up to proper operating temperature as fast as possible and then maintain The point of the thermostat flaps is not to provide cooling. Would you take the thermostat out of your Ford, your Toyota? no? then why take it out of your Volkswagen? ![]() It does not get cold where I live, or I only drive in the summer. This is self-regulating, meaning that when the engine heats up, the flaps expand, and when the engine cools down, the As the engine temp rises, the air over the cylinders gets hotter, causing the thermostat to expand more. ![]() This causes the linkage to move and the flaps to open. When you start the engine, heated air from around these cylinders causes the thermostat to expand once the air reaches the opening temperature. The flaps are nearly (but not completely) closed when the engine is cold. The thermostat flaps fit up inside the fan shroud on either side and are connected by a linkage to each other and down to the thermostat which is located between the #1 & #2 cylinders. We get all kinds of questions about thermostats and flaps. ![]()
