For a 2005 Chevy Trailblazer, it's recommended to use an ethylene glycol-based antifreeze that meets GM's specification, specifically DEX-COOL. This orange-colored coolant is designed for long life and should be mixed with water at a 50/50 ratio for optimal performance. Always check the owner’s manual for specific guidelines and maintenance recommendations.
DEX Cool
dex-cool coolant is used in most 3.1 engines,
A 1997 Jeep uses green coolant.
Any rated brand of 5W-30 conventional or synthetic will be fine.
The green stuff
dex-cool is made for Chevy vehicles but prestone has a universal coolant that works too.
A 1997 Chevy Cavalier uses a standard 50/50 mix of antifreeze coolant and water. This keeps the engine from overheating and from freezing in the winter.
