What type of coolant should I use on a 2004 Chevy Impala LS?

Hi there;
You should use long life "orange" coolant if the coolant in the car is that colour. Sometimes people flush the long life stuff out & put green in. so you'll need to look @ your coolant & decide from there. What ever you do don't add green to orange or vise versa as that will create sludge.
If you visit you local parts store & tell them the colour of your coolant they should be able to set you up.

Hope this helps, Good luck.
Farrout!

Organic Acid Technology Coolant (OAT) , use DEX-COOL®, spec. no. 6277-M (Orange)
