Is there a procedure for bleeding the cooling system? I had the water pump replaced under warranty then a few months later I saw dried coolant on the upper edges of the radiator tank. The radiator was then replaced under warranty also. When I have the heat on it goes cool until I step on the gas and start moving. I've checked and topped off the coolant tank and it just seems to me that there is an air pocket in the system. Any thoughts?

This is a problem for your dealer to address. Yes there is a procedure to bleed the cooling system, however, if you have insured that the engine is full of antifreeze, and you are still having this problem you may have a failed cylinder head gasket. I would return the vehicle to the dealer and explain your issue as clearly as you have here (provided this car is still under warranty) if there is an air pocket due to improper bleeding they should rectify it free of charge, as they were the last ones to open the cooling system. The tool we use is http://www.matcotools.com/catalog/pr...TEM-AIR-PURGE/
We have done 1000's of coolant fills with this system and have never, NOT ONE SINGLE TIME had an air pocket issue after having done so. I believe most dealers have a similar tool they use as well. The nice part of this tool is that it also shows you the integrity of the seals in the cooling system. It does this by pulling a vacuum on the system, at that time we always let the vehicle sit for 5 minutes, if the vacuum holds we are then assured that there will be no leaks in the system. The user simply attaches the coolant fill line to the adapter, and the system is filled automatically to the top, with no further user involvement. It really does do a fantastic job and shy of the self imposed 5 minute wait time the total from start to finish is under 3 minutes.
