Leaking coolant but I can't find from where, no puddles under vehicle, no steam. Heater has stopped working. Truck will top out on temperature gage when you first get on the freeway when engine is cold and then will drop down into the normal range within about 30 seconds. All of this started happening around the same time.

Is there any white smoke from the exhaust? Any coolant mixing with the engine oil?

If the coolant isn't going into the engine and not being burned, it has to be leaking out. Have you tried a pressure test on the system to see if there are any leaks?
