Kewl, thanks for the tip Im gonna try it this weekend...Ill let you know if that solved my problem....Also, tried to replicate the overheating.....started to do the over heat while 4x4 at low speed as i cruised around the block a couple of times. Also, let the truck sit at idle and moderate over heating..turn on the A/C let it sit at idle and whamo over heated pretty bad! Im at a loss! More insight would be awesome.
