Re: 700r4 Overheating
Nope. Still running hot. I think there must be an air pocket behind the thermostat. I have an electric fan that senses temperature with a thermal rod that's pushed thru the radiator near the top hose. When the engine runs hot I noticed the electric fan is not running. It's set to kick on at 180 degrees. That tells me the thermostat is not opening. The gauge is reading 220 and the fan is off. If I quickly rev the motor it starts to come down and the fan kicks on. I know the gauge is correct because as the temp spikes coolant start spewing out from under the radiator cap. It's definitely overheating. Tomorrow I will drain the system, replace the lower hose, drill a small hole in the thermostat to allow air to escape, reinstall and refill the system with the front of the truck elevated. If that doesn't work I'm doing to shoot it!
