Puddle under truck only when cold outside
I have a 04 f-350 Pretty much since it was new I've seen a puddle of fluid below the passenger side of the bell housing. This only seems to happen when it's cold outside. I just thought it was condensation off the motor mainly when you use the block heater. But it does it even when your not using the block heater. Yesterday My heater did not seem to be working properly. After some checking of the heater and vacumme system I found the coolant to be really low. I have added some over the years but not a gallon at once. My heater is working now. Would this point to a bad EGR cooler? The truck runs fine no white smoke or check engine lights.

I read a thread on this forum where one of our users had this exact same problem where it would only leak when it was cold and it did turn out to be what gotfu is talking about, the rubber fitting on the egr cooler.

I found the orange colored hose fitting. What a pain to get at. I'll check in the morning to see if i see fluid.

The orange hose was leaking. I ended up taking it in to the dealer. This was covered under the 100,000 mile warranty. They put a new blue hose in and change another gasket that was showing some sign of leakage. the blue colored hose is the revised hose for this . The Mechanic said he has replaced quite a few of these. Mainly when the customer comes in saying they have no heat. This is what started my search for what was wrong. It had leaked so much that the coolant was low and wasn't flowing to the heater core.
