I have a 2003 Av 5. 3 with z71 off road package. It has the tow/haul button which seems to work fine. I am having one problem. My temp gauge sits steady at 212 Idle or hwy speed, until I am towing my trailer which if I take on any grade it starts to rise rapidy. soon as I pull over it drops quickly down and even goes lower than where it usually sits on the gauge. If I'm going downhill the gauge drops to the mid 170-180, then soon as I'm on flat ground and at cruising speed, it sits at 212.
I have 64,000 mile on my Av. Does anyone have any ideas what this problem is.
Do I have a Rad, thermostat, fan or waterpump problem
Thanks
