  4. Look at the side of the coolant reservoir tank and note the low and high-level marks on the side. If the level is below the minimum mark, add coolant, or your vehicle may overheat.
  5. Very slowly, remove the cap by turning it counterclockwise. Perform this step only after the engine has cooled down. cadillac coolant reservoir cap
  6. Add engine coolant/antifreeze. Only add coolant type recommended by Cadillac. It is recommended that the system be flushed and filled with the recommended Cadillac coolant when possible.

If you add coolant or the level is already full, but you are still getting the warning light, there is a good chance the coolant level sensor mounted on the expansion tank is defective. Do not continue to drive or keep the engine running if the coolant light says on and the engine starts to overheat.
