I have 2000 Outback, first Subaru. Has 165,000 miles. When having belts replaced mechancic said I was starting to get some water weepage on one gasket and other might be starting. I add no cooent and have had it for a year. I was stnned when he said it would cost $1500 to rebuit heads!
I understand there is a coolant conditioner to add to readiator to help, problem is minor now. Anyone have comments or esperience,? Thanks...Don
