  • Depends upon the output of the engine. Just idling maybe 400 degF. Driving down the road at high power, maybe 800 degF. For a high power racer car, the manifolds actually glow red which would place their temperature at 1800 degF or higher.

    Engine combustion temperatures reach 3600 degF!

  • At least 220* f. Get a hand head heat sensor and get a correct reading. Welding shops should have them, check with Harbor Freight.

  • Hot enough to burn you quite badly if you touch it.
