Looking for some help diagnosing this problem before I rush out to the mechanic to open my wallet.
While working on the bus today I noticed a mysterious, and sudden(?) coolant leak! There is a pretty good drip going, all clean coolant. Maybe 1 drip per minute?
I haven't started the engine in a few days, the only thing I did today was move the driver-side master heater knob from the OFF to ON position while removing the knob.
I took some pictures of the part that is leaking - it appears to be coming from the lower hose attachment to this MYSTERY part. Photos are of the driver's side of the engine. I'm no mechanic, so I'm hoping someone can help me out here.
I'm hoping I just released some coolant back into the lines while opening the valve - I'll call a mechanic in the morning to see if I can get her in for a checkup.
As always, I'm very appreciative of everyone's input and time on this forum - I wouldn't be this far without y'all!
