Not gonna. Seems ok now. Currently blaming the tune.

 

The common coolant leaks are due to tired o rings. So, they actually seal better when warm and then leak in the middle of the night when it's cold and they shrink too much.
The system is a little touchy about the coolant level, but if you haven't had any work done on the coolant system recently (which would likely leave some air pockets), I'd think the tune, too.

 

Ok. Nothing out there this morning. Can check again tomorrow.

 

Ok guys my fans are screaming too. Read some of the threads I've tried this so far
1. Moved relays around still does it
2. Replaced pressure switch still does it
3. If i unplugg pressure switch fans stop screaming.
4. If i turn everything off plug back in pressure switch normal operation. When i turn on ac or defrost fans go back to screaming when i cut off the ac or defrost they are still screaming only when i unplug pressure switch or cut off truck will it turn off.

Any ideas do i need to get ac pressure checked have had the truck 3 years and never done anything to ac. Coolant levels are good

 

Does anyone know if Forscan can look at or change the low/high fan rpm temps?

 

I would think so. Mine began doing this in late summer when it was hot and the AC was on. Hasn't done it since. I'm going to have AC serviced next spring.
