Guys,

I just bought my 2nd EX. 01 LTD 7.3L. Little rusty underneath, but otherwise..I LOVE IT.

Been detailing it today and I noticed a small leak. It is under the passenger side frame rails.. There are 4 tubes encassed in spiralled plastic wrap. The tube that is leaking is the smaller diameter pipe. It is leaking a small amt of green stuff? Freon?? Coolant?? My coolant is green. Coolant bottle is full. I tried to tighten the bolt and all I got was about 15 minutes of hissing sounds like it was just letting out pressure. No fluid came out.

I have a feeling it is a a/c line with green tracebale dye. It is leaking at a joint where there is a bolt and it appears it is a 2 piece tube. Ft and rear.

Let me know if this is freon or coolant.

Thanks!

 

Definetly sounds like a rear A/C line with a leaky o-ring at the joint. The green stuff probably is tracer dye that is commonly used.
