Truck won't warm up.Is it my thermostat or do I need to replace my coolant?
The truck is not overheating, it's just the opposite. I drive about an hour to work and some mornings when it's 35 or lower outside my truck will not come up off of 140 during the whole drive. On warmer days it will come up but never even makes it to 190, anybody have a clue what's going on? I just don't want to start throwing parts and money at it until I figure out what's actually going on.

yep had the gasket in the thermostat too. It has to be the easiest thermostat I have ever put in. A 5/16 socket and 3 bolts it would be a great time to change coolant as you will lose some to replace the thermostat.
Take advice and use the NAPA part. It much cheaper and does not allow for as much temp flucation.
To completelly flush the system it is practical to remove water pump. That way you gea ALL the coolant out and can actually wash the water jacket out. Also the ONLY way to get the correct 6 gallon fill. Take heater hose off at head and flush with garden hose. When filling let coolant come up to open fitting and install hose. Now you got no traped air in system.
