Dexcool is the GM silicate free coolant. If something else has been added, you need to do a good flush. Mixing different types of coolant can have some nasty consequences.
You can find Dexcool just about anywhere antifreeze is sold.

I would use any Dex Cool approved coolant, but if you're on a budget, I would use any antifreeze that says that it can mix with any color antifreeze. The warranties are the same on both types generally 5 years or so.

The antifreeze sold at Walmart for car radiators is good (but don't use the pink antifreeze used for RVs for winterizing plumbing)

Use a 50/50 solution of water to antifreeze by volume when topping off yor radiator through the overflow tank.

the deville cooling system 12.3 qts of dexcool antifreeze an gm coolant supplement sealant p/n 3634621 specifically designed for use in aluminum engines.

Dex-Cool is what comes from the factory.

You have to see if the fan works, see the thermostat, check if you have no drain coolant.Nota You should vary the thermostatato.Gracias good luck and I hope your comment ...

where can locate the engine coolant temperture sensor.

The engine coolant temperature sensor is located on the driver side of the engine near the rear of the engine compartment
