I replaced the thermal bypass valve on my 66RFE and it hasn't stopped leaking since. I used good quality ATS brand.
When I first installed it, I did not torque the lines very tight. I think instructions said something like 27 inch pounds. The thing leaked like bad, so I tightened them more and it leaked less. So I tightened them again and they stopped leaking, so I thought. See pic. It is leaking out the side of the lines that do not have the clips on them.
I towed my camper today and noticed that there was fluid all over the passenger side of my truck. Looks like about a quart leaked out for a 100 mile trip. It wasn't leaking when I left home.
My question for you guys is, do I need to tighten the lines more? It's already very tight, I really don't feel comfortable tightening it any more unless I'm supposed to. It's already way over the 27 inch pounds they called for in the instructions.
Also, I topped off the fluid. I'm worried that since the leak started after I started towing, is it going to get worse on the return trip home? I plan on keeping an eye on the fluid level going home (stopping periodically to check it).
