Ive had a small slow coolant leak for a month or so and have been unable to locate the source.
Today after running around town I parked the truck an hour later my wife asked me, Isn't Anti Freeze pink? If so it is dripping under the truck.
Long story short, the white plastic fitting on the outlet for the heater core had cracked. I had not removed them when the EGR cooler fell off, because frankly, at the time, I had no idea they were removable.
As of now they both have been removed and no more leak.
Am I glad it opened up today. We are leaving tomorrow for a 5 day camping trip to Monroe, LA, following the ULL baseball team to the last conference game series of the season. Now I can drive relaxed not worrying about my coolant level constantly.
I would have also replaced the Turbo Cooling hose but could not find any High Heat 3/8" radiator hose in town. I ordered a foot and will change it when the parts come in and I have time to go back into there.
