Im not sure what your referring to, maybe you could post some pics. There aren't any coolant lines connected to the older throttle bodies. There may be a difference in the 05, ive never worked on the new trucks, but that may be the case seeing as the have moved to the electronic throttle body. your connectors should be safe if you just avoid spraying them directly with water. Use a cleaner that is safe for the inner finish. Dont use anything abrasive or acidic. Its just needs a little elbow grease and MAF or carburator cleaner. I used a toothbrush, the original poster used wirebrushes.
My advice take a picture of how you took it apart to make sure its the same when its all back together, and remember there is nothing in the throttle body that should bring coolant into the motor...that would have detrimental effects on gas mileage (aka hydro-locking) to say the least lol.
