Glycol leak

We were getting ready to take our T@B to southwest and testing heating system plugged in. No heat coming on, looked in Alde cabinet - all looked good. Pulled up bench seat and glycol is leaking from the back right where the heating system runs. Any thoughts on what I need to do to troubleshoot this? Thanks. Ginny

Search the forum on your title & you'll find discussions of similar problems. Some have had cracks in the base of the reservoir or "expansion tank" which is located above that area in back driver-side corner. If it's like ours, remove two screws in a side panel to get to it.-Brian in Chester, Virginia

I just happened to take a photograph yesterday showing where the Alde reservoir is located in the 320S, as described by @BrianZ , so here is that photo. The panel slides right out after pulling out the two screws. Pretty tight quarters in that area, but you can always use a mirror (or take a photo with a cell phone) to see if any glycol has leaked out and puddled up at the base of that compartment. (Greg)
