Spun wrenches for yrs then worked for MFG's as an instructor on car and Diesels. Not much I cant do myself. One of them i cant is re-coring a radiator on the side of the road, lol. what blows my mind is the difficulty in finding Radiator shop that would work on it. Give and Idea of size the system holds 15 gal of coolant. I know that "what could happen" feeling. Sometime I wish I didn't know. What i did find out that the new Monaco company has very little information on there coaches that where made by Navistar or prior. kinda sad.
