    Does anyone know either a part number or size (and material) of the little o-rings that go on the metal lines at the radiator? We just replaced the radiator and reused the o-rings (original, 2003 3.7L with 145k miles). And, either I'm nervous about overtightening or the orings are worn out, since I've snugged them and still get a tiny residue of trans fluid at the fitting.
    Thanks for any advice. I just didn't want to risk damaging anything by overtightening.
