What kind of engine coolant gold or green for 2002 Mercury Sable.?

The 2002 Mercury Sable's coolant type depends on what the manufacturer originally specified. You should NOT rely on color alone. Green and gold coolants are often different chemistries (e.g., silicate vs. OAT - Organic Acid Technology) and mixing them can cause problems.

To determine the correct coolant, check your owner's manual. This is the most reliable source. It will specify the type of coolant and the proper mixture ratio (usually a 50/50 mix with distilled water).

If you don't have the owner's manual, you can:

* Look for a sticker under the hood: Sometimes, vehicle manufacturers place a sticker near the radiator or coolant reservoir indicating the recommended coolant type.

* Check the coolant reservoir: The type might be printed on the reservoir itself.

* Consult a mechanic or parts store: Provide them with the year, make, and model of your Sable, and they can look up the correct coolant type for your vehicle.

Using the wrong coolant can lead to corrosion, damage to the engine, and costly repairs. Always use the coolant specified by the manufacturer.
