Chevy 6.5 diesel engine-HOT
1994. It used to be a school bus, now a camper. 270K miles, automatic. When accelerating or going uphill, temp gauge goes into red. The last mechanic says this is normal. Red isn't normal to me. What say you?

You could do a compression test at the engine to see if it is you'd more or less live with it. Now let's say the engine is actually in good shape and isn't low compression. And that case you probably just need a new radiator
