Does anyone know the procedure for removing air from the surge tank or coolant system? Took my truck to the dealer they said no leaks just needed to remove air from the system. Kept my truck for two days and several days later the message returned.

Fill procedure is in the manual, but as above if it's only down a little just add some and it should self correct after a couple of heat/cool cycles.
Common to have to add a little to a new one.
What year is the truck?
How many miles/how long in service?

If you want to try it yourself:
1. Remove the coolant surge tank pressure cap when the cooling system, including the coolant surge tank pressure cap and upper radiator hose, is no longer hot.
For 8-cylinder pickups, turn the pressure cap slowly clockwise about one-half turn. If a hiss is heard, wait for that to stop.
A hiss means there is still some pressure left.
For vans, turn the pressure cap slowly counterclockwise about one full turn. If a hiss is heard, wait for that to stop. A hiss means there is still some
pressure left.
2. Keep turning the pressure cap slowly, and remove it.
3. Slowly fill the coolant surge tank. Do not let the coolant
level go above the indicated mark in the tank until after the engine comes to operating temperature in Step 4.
4. With the coolant surge tank pressure cap off, start the engine and let it run until the engine coolant temperature gauge indicates approximately 90 °C (195 °F).
By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, slowly add more of the proper mixture to the coolant surge tank until it reaches the indicated mark.
5. Replace the pressure cap.
For 8-cylinder pickups, be sure the pressure cap is locked.
For vans, be sure the pressure cap is hand-tight and fully seated.
6. Verify coolant level after the engine is shut off and the coolant is cold.
If necessary, repeat coolant fill procedure Steps 1–6.
If the coolant level is still low after having followed these steps twice, have the coolant system checked by a certified technician at the dealer for a possible leak.
