How hard to get to heater core?

2000 Winnebego ultimate advantage... new owner

I can smell radiator fluid from my dash vents... I assume its the heater core or plumbing leading to it.

Took off the cover for the instruments, can't see the heater core. Went under the RV, cant see the heater core...

No dripping, just a smell. Prior owner had to add 1 gallon of antifreeze every 3500 miles... my guess is, this is the cause... but again, no wetness on the frame or carpet...

How do I get to, and inspect, the heater core?

I see valves in the engine bay that look like garden type valves, I assume these are to shut off coolant to the front of the RV?

Yes the valves are to shut off coolant flow to the dash .

The dash heater and A/C was all a Winnebago install so questions about access would be best in the Winnebago owners forums .

But If you could identify the HVAC system , it would help ; Evans/Tempcon was common back in the day .
Name is cast in the plastic housing , above the gen set in my coach.
