This just for the summer temperatures.Colorado winters it’s just fine.Someone suggested disconnecting the A/C higher pressure side and the fan maybe on sooner and longer.There should be a way to override fan when needed and not mess anything up. I will look at the wire diagram for the cooling fan sy...

1998 S70.Is castrol automatic transmission fluid good?or is there another brand that would work better.

Which cooler would you recommend?

Yes in Colorado.
With construction holdups and the hot temperatures ,Would like the fan on more.

Radiator was just replaced.Just want to have the option to turn fan on if needed.

Will I need to ad a diode so it not feeding back to the ECM?

Looking to ad a bypass switch to turn on cooling fan for those days when sitting in traffic. No A/C on .Is that a way to run fan without out having ECM turning fan on.This is for 1998 S70.Would like to ad switch without messing anything up.See if anyone has come up with a way to do this.
