Found a couple new drips under the very front of my JL 3.6. Small drips, found weeks apart. Fluid is red and very low viscosity. When compared to fresh coolant (pictured, dripped some out of a bottle next to the Jeeps drip) the color is slightly different, and they mix together well. Not like oil mixing with water. The color more matches what’s in the coolant surge tank.
Leak is coming from the drivers side of the back edge of the radiator. It’s mostly dry, but there’s red fluid on it. Pictured from above and half way down. This is definitely where the leak is dripping from.
The Jeep has needed about a 1/2 gallon of coolant (added to the surge tank) over the past year, but no running leaks found. No coolant in the oil, or steam in exhaust.
Does the transmission fluid have any path through the main radiator (integrated trans cooler)? Or is this definitely coolant?
In either case, more investigating is required, but I’m thinking it’s radiator time.
My worst fear is coolant communicating with the transmission, but since a half gallon has been needed, no trans issues have popped up, and the drips are clear red, I’m thinking not.
