Just dug out my 73 Brave for spring and noticed the heater on the passenger side under the dash area seems to be leaking antifreeze - from what I have read the heater core leaking is common.  The unit is marked Evans.

Does anyone know if it will leak anytime the RV is running, or will it only leak when I flip the heater on ?  Want to be sure I can run and continue to use the RV safely to go on a trip, as I don't have time to get it fixed right now.

Thanks for your help.

It will leak even worse once the engine is running because then the system will be pressurized. Sorry to say you will need to get it fixed or bypass it.

Thanks for the response.  Fun too that it is placed in a hard to work area !

I'm with Rick. The quick fix is to just by pass the heater. Just get short  piece of heater hose and loop it at the engine. That's the quick fix. Over the summer pull yours and have it fixed or pic one up and replace yours. Hm?
