Local shops don't want to work with the aluminum radiator. This is large unit out of a pusher. The good ones that could have or would have done it around here are out of business or retired. The ones you can find want the same cost to repair it as a new unit would cost from the company that makes them for Monaco. Still waiting on Saldona to give me a price. I was hoping to find a good shop that could work with this or build the new one without a $2100 price tag.
