Thanks, Jaime and all for the suggestions. We took Hildegard on a 10 mile road test, and she did well. Once she warmed up, temp stayed at 80-85 with a quick blip up to 100 at the first light before dropping right back down to normal where it stayed for the rest of the trip. I definitely have to

Well, a diesel engine at idle does not make very much heat, so I think it is reasonable that only the top of the radiator and the top hose were warm. T-stat might be good. A road test is required next, I think. It may be prudent to replace the t-stat on principle. -- Max Dillon Charleston SC

Hello again. I decided to “blindly” plunge into the cooling system, removed the radiator cap and filled it. Afterward, I remembered the procedure of filling through the top hose, so I removed it, topped off the system, reinstalled it, tightened the clamp and fired it up. Nothing was leaking, so
