Ok guys. My 04 is leaking coolant. I was thinking water pump. Antifreeze and whole front of engine is wet when driven. I let it set a couple days. Sitting in the driveway idling I don't see anything up front or under the truck. I did see something towards the back of the engine but smelled more like oil burning off. I drove it a couple blocks and back home front of engine is wet again. I am unable to see exactly where it's coming from.
