AC condenser appears to be leaking antifreeze.

    Does anyone know if the AC condenser with the integrated transmission cooler can leak anti freeze? It looks like antifreeze is leaking from the cylinder tub next to trans cooler lines on the ac condenser and not the radiator. I guess I am going to have to take it apart tomorrow and inspect.

    The condenser has refrigerant, and the tranny cooler has transmission fluid, no antifreeze there. Maybe somehow coming from the radiator.

    There's no coolant associated with the AC condenser/transmission fluid cooler. Really need a picture of the leakage. Coolant is pink and sticky, ATF is oily and red.

    If your "cylinder tub" is that cylinder on the passenger-side end of the condenser, I think that is an accumulator-drier for the AC system. Any liquid leaking from that cylinder is likely compressor oil. You might be looking at a new condenser, system evacuation and re-charge.

    No pictures yet i just took out the radiator tonight and I am going to look at tomorrow and see if it has any holes in it. I found a bolt lodged between the condenser and radiator and think it may have put a hole in it.
    Thanks everyone for your response.

    The fluid leak was pink so I am thinking a small hole in radiator.

    That conclusion would be supported by low coolant in the overflow reservoir. If there's no coolant in the reservoir, then remove the radiator cap (only when cold) and check coolant level in radiator.
