Well, a buddy had a good fan motor so we switched them out and had to change the plug because they were different. It now runs both when AC is on. We let it run 5-10mins with AC off and it never kicked on but gauge shows at being slightly past 1/4 gauge so I doubt it's even hot enough.

 

Oh and I may have found the only reason I was adding coolant every few days. The radiators burping it out. It cap fit loose so we swapped one out.

 

To get the fans to cycle when the ac is off -depends on outside temp- but yoy are looking at something closer to 20 mins running in the drive way.....maybe 10 if you have just gotten back from a nice lone drive.

Good to hear you got both working with the AC on.
