Why do you need to know the temp of the exhaust at the manifold ??? Suggest you contact cummins engines ,though they may not know due to the millions of variation..Do you want to know the temp when the engine has just got to operating temp whilst left at idle from cold ,or after it's been driven round the streets for 8 hours ,or done a 8 hour motorway drive at max speed ???.To be honest i don't think Cummins or anyone can answer that question..Have been repairing trucks for longer than i care to remember ,and never have i needed to know ,or has anyone asked such a question
