High and Low are not fan locations..they are in reference to the fans speeds..........
..High fan is for coolant of 105 and low fan is for a/c high side pressure.
..which is why he wants to look at thermo first..he claims it always runs hot , so I assume that means regardless of ambient...and Viscous is air temp sensed, whereas aux fans are coolant temp sensed..so , a high fan at any ambient points to either a blocked radiator/debries between rad and condenser/ or a faulty thermo..and any Tech will tell you the easy diagnosis is to change the termo first b/c of probability percentages.
We see so many guys change fans and radiators and Vicous units, etc...and then they finally change the Thermostat..............go figure ????????
If conditions point to a possible thermo problem, change it and get it out of the equation. One of the few diagnosis that a part change is in order for confirmation. It is not to say that is Definately the problem, it is to say that it is Highly Probable and easy enough to confirm by replacement before getting into the $$$$ trip.
