ACDelco 10-101 DEX-COOL Extended Life Coolant – 1 Gallon

This was a bit expensive and some other GM Coolants cost less, but always get the full strength coolant and NOT the 50-50 mixes. You’ll need tful add 50% water for the full strength varieties. Be cared the coolant you add is compatible with the coolant in the cooling system, because mixing different kinds can cause problems. Always keep your oil and coolant full up and WATCH THE HEAT GAUGE AS YOUR TRAVEL. I believe every drive should be aware that overheating can destroy your engine.
