Hey guys....I installed the PCMofNC two relay fan kit with LS1 fans in my 09 Saab not too long ago. Well...I went to tow my camper trailer after that and found that the e-fans were not keeping up with the demand in hot weather. I was running 235 coolant and 223 trans on the hwy...no way that would survive the mountains. I unfortunately threw away my stock fan recently when I moved. Anybody looking for a good deal on electric fans?
