I have a thermostat, and cable/fan. That is it. My engine bay pump is hooked up to open air and it never turns on........
I have searched google, type IV secrets revealed and this forum as well as others. I can't find the pictures I need or info I need on when/how the air pump in the bay is activated. I'm trying to not blow up my good condition 1800 fuelie, and I get the feeling with the hot muggy weather coming back here a working cooling systme is probably A1 before I start driving it semi regularly. Does anyone have any photos? Tips/hints? From what I was told the pump just evacuates the engine bay air below the tin so it is not recycled back through by the cooling fan and back over the heads? (IMG:style_emoticons/default/confused24.gif) I suck at air cooled cars. |

thermostat expands and slacks the cable when hot, contracts when cold and pulls the cable. So the thermostat, under heat from the engine, expands, thus slacking the cable and allowing the flaps to come to the position so that it is the correct position for hot engine cooling. That's why, what Zach said, if the cable breaks, the flaps go to the default hot engine position. When the thermostat cools, it contracts and tightens the cable, pulling the flaps against the spring tension to the cold engine position.
