Im working on my new S83P getting it painted for the farm and going through the systems. The coolant is leaking out of a fitting at the top of the engine. It looks like this fitting was attached to a hose at one point but corroded and now it's leaking at the base. The fitting itself is not corroded and can be moved with a wrench. Can anyone tell me what this is? What it is for? Was there a hose connected? I've uploaded a photo. Thank you for any help!
Looks like it should have a hose on it. Can you track the two lines from your heater core back to the engine and see if they both are connected to the engine?
Update, there was a line buried that I couldn't see that was supposed to be connected to the mystery fitting. Once I hooked it up, new hose clamp and all is well. Thanks!
