Intermitent problem, Temp gauge barries 260 and engine doesn't feel heat can touch the engine block, replaced the thermostat and water pumped and gravity blead the air out of the system. Can start the truck up and let it warm to temp and heats awsome go a half mile down the road and the gauge barries and blows cold air, after another half mile i assume the thermostat opens and temp gauge reads normal and heat blows fine for rest of day.
