What kind of antifreeze should you put in a 1999 Chevrolet suburban?

A 1999 Chevrolet Suburban requires 50/50 mix of ethylene glycol-based antifreeze and distilled water. It's crucial to use a coolant that meets Dex-Cool specifications (GM's own formulation). While other antifreezes might work in a pinch, using something other than Dex-Cool can lead to corrosion issues over time in this vehicle's cooling system. Always check your owner's manual for the manufacturer's recommended coolant type.

Important Considerations:

* Never mix different types of antifreeze. Mixing different types (e.g., Dex-Cool and traditional green antifreeze) can create a gel-like substance that will clog your cooling system.

* Use distilled water. Tap water contains minerals that can contribute to corrosion and scaling.

* Check the coolant level and condition regularly. The color of the coolant should remain a consistent color, and the level should stay within the specified range on your radiator's overflow tank. Cloudy or rusty coolant is a sign of problems.

Always consult your owner's manual for the most accurate and up-to-date information specific to your 1999 Chevrolet Suburban.
