It mostly stays at 215 on the freeway but if I have to stop on a trail and it loses it ability to control the temp and overheard after a few minutes

Even after we start moving and I personally never want to shut an engine off in the middle of the forest with a auto trans

I eliminated the stock mechanical and electric fan, installed a new stock radiator witha 195 thermostat with a pair of derale fans set to a pusher configuration truck runs at 200 constant even with air on, set it up with a switch it can be turned off in mud or water got the fans from rustys

Salt has turned a good portion of the rad into flakey corrosion,just replaced the t stat and fan clutch last week with no improvement.

I just put in a 3 row rad from radiator barn. All metal design. Everthing else is OEM. New water pump and 195 degree thermostat. Never even come close or ever heating. My e fan only kicks on with the a/c or the super hot days. Plus when I replaced it all I noticed the shroud around my clutch fan was cracking...so attempted to remove it to possibly fix it and it broke in many pieces. Never replaced it. So that gives you an idea on how good the rad works. I'm very halt with it. This summer here in Western pa has been pretty hot too.

cheap and work well, i wasnt sure how well they would work but i purchased these at the end of my build on the stroker and my budget was about gone, ive been more then impressed with them so far, if they last a year ill be happy, they have been sprayed with coolant twice now from faulty radiator caps while tweaking the motor and still run strong with plenty of cfm
