In an 2004 Envoy, you should just use a screw driver. Had to end up taking the dash apart anyway to get the lighter out of dash. GM Quality at work.

My family has used Prestone Antifreeze (50/50 or concentrate) for over 50 years. Unless a vehicle specifies to use a different make antifreeze/coolant, we use Prestone. Prestone products are excellent products & do what they are meant to do.

Used in a 1999 Jeep Cherokee XJ, seems to be the same as any other antifreeze I've used. Tests fine for the weather here in Indiana.

Did a drain and fill tranny fluid on Camry 96000 km with Valvoline Maxlife ATF. The old tranny fluid was black in color. Transmission was less noisy and more smooth after drain and fill.
