Howdy all. I have a 99 with the V10 engine. I have a coolant leak on the rear passenger side of the engine, like most other folks on this line. I changed the heater core last night, all hoses look good, everything on the top of the motor looks dry. The drip was back this morning though. It is a pretty steady drip. It seems to be running down the passenger side tire well. I have been under the truck but can't really track where it is coming from. I am going to take the tire well plastic off this afternoon. Any suggestions on where to look? Same original symptoms as most other. Fog in the truck, burn antifreeze smell, and there was coolant in the case for the heater core.
