Does the engine derate because of low coolant? remember that it is a 2000 C 12 in a Kenworth truck. My 2003 C 15 does not derate when low on coolant.

Hi. Thanks for asking your question and requesting me. Sorry for the delay. I will try and help you out.
Does the yellow or red engine warning light come on while driving?
When you say crappy. Do you mean it has low power? Or does it miss or run rough?
