You need to retrieve the trouble code to understand which component circuitry is causing the problem.

If it is the coolant indicator light that is showing, recheck the coolant level. If level is low, you have a leak in the system and would need to verify the source which might require a pressure test.

You need to have the Engine Computer scanned for stored fault codes... there are 50+ reasons
why that light could be on, ranging from a loose gas cap to a faulty sensor in the engine.

The low coolant & oil might not be related to the reason why the check engine light is on.

You need to proceed with caution here, at that age and when overheated, those motors have a strong tendency to have catastrophic internal damage, and the problem can hide for a long time, especially if you just take it on short hops. It might start with splitting the seam on the expansion tank, and then you have a choice. Just saying...
