Coolant in storage bays

Started the coach this morning for the first time in several months.  Stop engine light came on, and both storage bays are filled with what I believe is engine coolant. 
Any ideas on where I should check first?
Thanks, Mike

Sounds like the lines coming from the engine to the heater core,if so one scenario would be to block them off at the engine and
let the new owner deal with it.Would be a labor intensive job.

Be sure to dry it up-- you don't want the moisture, chemicals or smell to permeate the foam insulation in the basement floor.

That big a leak should be easy to locate.  May have to drop the basement ceiling trays, access the Aquahot (if equipped), back of the water heater (if motor-aid), etc.

Another possible source of engine coolant: if the coach has the Motor Aid option, hoses circulating coolant to the water heater might crack or completely break.

Giving that its a U-320 it probably has an Aqua Hot. My guess is the engine pre-heat lines.

Check the Aquahot loop. I have had the elbow go out on mine three times in 20 years

I also had a rat chew through mine once. In that case, it would only show itself under pressure so I eventually found it by checking for leaks while the AH was calling for heat
