Your check engine light will not come on because your coolant needs to be changed. The only way to be totally sure why it is on you should get it checked with a computer at a dealer or service station.

Replacing the battery should not have triggered the check engine light. The check engine light comes on when there is a problem with the emission system. Saying that, I would drive it for a while to see if the light does go out. If the light does not go out have the ECU scanned to retrieve the trouble code. Then use this code to diagnose the problem.
