Exhaust Tempt Gauge Reading

I know nothing about this but my first thought was I bet his son/daughter took it for a spin! Had that happen to me when my eldest decided to use my car while I was at work - thought it odd that the car looked to be parked differently and the engine was warm. I started taking my keys with me to stop that sort of thing.

Kind regards

The EGT gauge is no different to a normal temp gauge so I guess you've answered your own question.

Unless there is another heat source.

If your truck has not been used for some time any gauge that is fairly calibrated and its minimum calibrations are less than the ambient temperature should indicate near the ambient temperature. The reading may not be exact or repeatable if there is not a good free airflow like under your bonnet.

hi clarkey
my engine watchdog temp gives ambient readings before i start the engine for the first time day or night
so yes your assumption was right
cheers

Thank you all for the response, it confirmed what I was thinking.
