Howdy folks!!! My 2010 JKU spends a great deal of time in the South Padre Island National Seashore sand, and yes, when wheeling, the engine temps run a bit high. Per my observations, the stock radiator/fan appear a bit undersized. Any recommendations for upgrading both would be most appreciated.
theres a mod i was reading about this morning its not a radiator upgrade but maybe it will help. this guy had underhood temp issues so he got a autostore hood scoop(pick yours from wherever) and get an 8" electric fan maybe 20$ online and bolt it under the scoop then wire to an aux switch or your current fan set up.ill see if i can dig up his thread
Start with what is cheaper. The RS5200 spal fan with shroud is a great replacement fan and is an easy drop in replacement. I coult'nt find it on Tellico 4x4's site but that is where I got mine from. Griffin makes a replacement radiator for the jk. Also you could do some hood louvers like poison spyder or synergy as well.
i did one. its a different model number that appeared to have a slightly larger motor and more current draw... but its still under the rating for the P.O.S. stock fan motor. it really does suck.... but its a good kind of suck.
