My 2002 Wiinebago ultimate advantage dash heater core was leaking. I replaced it and everything is now working well. Although it is the first time I change it, looking at the way it was setup, I know it was changed by the previous owner.
I have read that the leaking core is a recurring problem. I am wondering if someone has found a solution to fix the recurrence of the problem.
I have read, somewhere on this site, that the problem is caused by electrolysis due to an approximately 0.5 volt voltage in the heater core "coolant". The suggested solution to this problem is to ground the heater core.
I have also read on the following website: https://macsworldwide.wordpress.com/...-electrolysis/
that grounding the heater core might cause the core to become an anode and therefore promote electrolysis.
The webpage also suggest that the installation of a flow restrictor might solve the problem.
I am wondering if any member as found a lasting solution to this problem.
