2000 Monaco Knight Diesel Pusher, 55,000 miles,Roadmaster Chassis, 5.9 Cummins Engine
Aluminum radiator- Tubes leaking at header on both ends, top half of radiator.
Cause: may be due to vibration and/or twisting of radiator as motorhome moves. Radiator mounts to vertical supports w/ 4 shoulder bolts and rubber washers. Aluminum susceptable to this type failure.
Suggestions received from radiator repair shop and individuals who have worked on design and installation of large radiators include:
1. Replace with copper construction as can withstand vibration and twisting much better than aluminum.
2.Mount radiator from 3 points instead of 4 to allow to for twisting of mounting frame.
Called Monaco Customer service. Tech had only heard of maybe a couple leaks.
Anyone experience this problem? If so, what's been tried/ done to fix it?
Thanks for any help.
