Thanks cutout, it goes into the shop when I get home. I do have to stress to the mechanics that I'm out for 3 to 5 weeks at a time and will easily put on 10,000 miles before they see me again. I'm the only OTR truck they work on, everyone else is local and can deal with a breakdown. That's why they replaced all my belts the last time and a bunch of hoses.

the salt and road grime really breaks down the copper tubes and fins. the fins will get very brittle and will crumble. the first place it starts is in the lower corners. if you get chances, hose it down with fresh water. steve, i appreciate your posts. i'm learning a bunch off these boards.
