Any suggestions? Witt, I have a feeling you are referring to the check engine light. The first item I would check is the coolant sensor connection and make sure there is enough coolant in the New over flow / expansion tank. Rich. Share this post Link to post Share on other sites
jleamont Report post Posted June 5, 2021 You will need to scan the ECM for codes to determine why it’s on. Is the low coolant sensor reconnected, did you disconnect anything else for access? Monaco (Cummins recommended) uses two engine lights for faults. One lights up WARNING the other Check engine. Warning is a fault with lower concern that won’t strand you. Check engine, may the lord watch over your wallet Share this post Link to post Share on other sites
