GM cooling system check

[babyjay8495]

Anybody have some ideas for a coolant pressure tester for my 98 malibu? It has the sealed radiator and i believe i need an adapter to screw on the overflow bottle. I've seen a few different ones and was unsure which one would work. I also have an 03 silverado and 07 trailblazer that i would like to see if they would take the same adapter.

Have heard of a hack where one takes an extra surge tank cap and drills it for a tire valve stem.

One would probably want to use a hand bicycle pump with built in gauge to pump it up though.

I found this on amazon.com for cheaper. Looks decent, except one person who rated it wasn't totally impressed with it. Anyone have any experience with it?

I don't have a pressure tester and what I did was to hook up compressed air, thru a pressure regulator set at 15psi, to the coolant overflow hose.

Worked very well.
