To start off I have an 08 JKU L96,6.0,6L80,using the Motech kit, tons and 40's. I was driving through Death Valley over spring break, the outside temp was 95. My engine usually runs between 200-210 range. This day it got up to 230 and I was just driving down the paved road. I have a CSF radiator with CSF 20psi cap. I have not had any radiator issues in the three years after my engine swap. I am looking to see if anyone has upgraded from the stock 3.8 fan to the Pentstar or Camaro fan and was it worth the $700. I have also heard that I may need a new TIPM to control the fan. Or am I better off adding a Poison Spyder hood vent for $180 to help expel some hot air.
