Do yourself a favor and go to Napa and get a little bottle of UV coolant dye and put it in your expansion tank and buy a little black light. Then power wash your engine and it will be pretty obvious where it is leaking from. It will glow like your coolant is radioactive. Make sure you buy coolant dye don't let them sell you R134a dye or block testing fluid or transmission fluid dye.

Do you need uv protective glasses with a uv light? I am going to checking mine soon. I bought my light off ebay.
