Yesterday I started to remove a rear heater from a 2000 Blue Bird Mini Bird w/ a GMC chassis. I unscrewed the clamps connecting the heater to two thick rubber lines. I glanced over thirty seconds later and some fluid was leaking from the lines! I thought "uh oh" and reconnected the lines. From the research I've done on others' posts I think the fluid is coolant. How can I remove the heater safely? Are there 'caps' I could install to seal the lines? Is this coolant engine coolant? I don't want to mess anything up in the engine
. All help is appreciated! I don't see any valves for switching off the lines. Maybe I'm looking in the wrong spot?
