Santech Industries MT0671 Radiator Fan Switch - High Performance Cooling Switch for Cars & Trucks - Perfect for Overheating Prevention & Engine Temperature Control

The switch installed just fine, and fits like an OEM part, the problem is the pressure set points. I purchased it because it came with the pigtail, o-ring, snap ring, and switch, but it doesn't do much good if the pressures it works at are off. The specs for a purple compressor mounted switch is on at 283, off at 210 to control an auxilary condenser mounted cooling fan. This one comes on at 250, and doesn't go off until 190 which is the specs for a primary condenser cooling fan. This makes the electric condenser mounted fan run more than is needed. Unfortunately you have to evac the system to change this switch out again.
