Cooling system diagrams for the Type IV 1.8?, My car has no cooling system! Options

[ghuff]

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?

I suck at air cooled cars.

Make sure that the flaps inside the fan shroud work right. They are supposed to fail open. Mine failed closed.

I took the bellows off the engine and static set the flaps open. I don't trust them. my car won't drive in the winter, so I am not to worried about really cold starts and long warm up times.

I think I may just do this, if I can't get it proper. Insurance it will not overheat.

The cable has already fallen off the pulley twice now.....

...then you need to tighten the nut that clamps the cable with the cooling flaps under tension. I am having a hard time figuring out how to explain this but if your cable is coming off the wheel, then the thermostat is loosening the cable so that is why it's coming off the wheel. Did you do this;

Without touching the shaft that the flaps are mounted to, observe that there is a spring on the shaft near where the cable will be clamped. If you push down on the place near the spring, the little piece that juts out from the shaft, you should be able to push down on that piece and rotate the shaft against the spring pressure. The shaft rotates about 50ish degrees (?). You have to rotate the shaft against the spring pressure, then clamp the cable tight. The thermostat works in such a way as to relax the spring pressure on the shaft as the thermostat heats up. As it heats up, the cooling flaps shaft adjusts to the warm engine cooling mode. When you shut off the engine and it cools down, the contracting thermostat adjusts the flaps to the cold engine/warm-up position.
