Chevy 6.5 diesel engine-HOT


Topic starter

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?

Well of course it's not normal but it's got 270,000 mi on it. If it runs okay. Otherwise, odds are the engine is just extremely worn. 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
