I have a 3126 in a school bus that heats up, runs like a champ on cold mornings but in afternoon heats up and throws an engine light and starts to run rough and lacks power, I pull over and shut down and it starts up and runs fine for about five minutes. it only does this when temp aproaches 220, I checked electric fan clutch and it works ok, it has 129k miles and just started doing this. runs cool on long flat roads with no stops, but as soon as I have to pull a couple hills, or have to stop multiple times for kids it slowly heats up. friend said to replace "Injection accuation control regulator" and "Injector accuation pressure sensor" he said they are magnetic and the high heat affects them.

'I listed a surplus Watermota diesel on DieselEngineTrader. It took a few months to sell, but I was delighted as the engine was quite obscure and I never thought anyone would buy it!'
