Default Re: Hooked to my new boat :)

Is your guage showing hot or is the PCM showing hot? I'd double check against the PCM to see what it actually reads. Many of my GM vehicles have shows 210 degrees and were really running 190 to 195. I'd also check my water pump and flush the system and install a new t stat. if that doesn't work, something is in the radiator. no way you should be running that hot with 7K behind it. I've had friends pulling 10K 28x8.5 car haulers in the FL heat without issues at 80 MPH.

Also, what is your fan clutch doing? Can you feel or hear the fan roaring (like a semi fan engaged?)

Post up and we'll trouble shoot from here.
