Review on Maximize Engine Cooling Efficiency with the Four Seasons 35879 Radiator Fan Mounted Cooling Fan Temperature Switch by Gary Perry

pt # 35879 arrived quickly, assembled well in 2 days, easy to install, good clear instructions. I installed this on my jeep 4.0, just turning it on makes the fan run for 30 seconds at a time! I think it should stay on until temperature is reached. runs cooler but cold. Long term I don't think it will stop overheating. But let it run, switch to a relay. So I set a fancy fan relay to full time or on or off with a switch. off including after temperature. Always with Tranquillity.,
