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.

I had to replace the radiator in my parents Sport Trac. This was do to a crack in the top plastic of the top of the radiator. The truck had lost very little coolant. I generally use the factory coolant. I picked up this one gallon to add to the existing coolant in the cooling system. I figured that the one gallon should suffice to top off the system. Caught this on sale for basically half of what the factory coolant would cost.
