Engine temps

[Brandon Rogers]

Guys-
A coupel questions regarding a/c.  Patient is an '84 urq with 3B motor.  I'm getting the a/c system ready for action - first time since the motor swap.  This will be one of only two 3B urq I'm aware of that will have operating a/c...not that it matters.  Anyway - my questions-

1 - With the a/c running do the engine temps go down around town due to cosntant fan in use?  Or go up due to more strain on motor.

2.  Which fan speed activates 1, 2, or 3?

3.  Does the fan run constantly - like even when you'r cruisng at 80 on the highway?

Thanks-

Brandon
