Think on this subject, I can speak for myself and other members, most have run into this. The needle gets really close to thered, but as long as it does not go into the red,yourO.K. ~~~~</p>
ALWAYS, keep your radiator clean, pull the " mesh" screen out and not onlyclean it, but raise the bed of the RTV and wash out the radiator from that back side also, get all from the top to the bottom ....</p>
Also,keep alistening ear out on the fan, it should becycling in and out, turning on and off by the temp of the engine. When the needle gets really close to the "RED" ,THE FAN SHOULD BE A KICKING IN , and coolingdown some. When the fan kicks in, you can actually see the temp falling . That is what it suppose to do !!!!!</p>
Remember, these machines suck air from the side, not the front like your truck , so it is not getting any " JAM"air to help cool, all is having to be brought in from the side. So expecially whenit's hot and just sitting still, it will get a little warmer and you should be hearing the fan kick in and out !!!!</p>
