Re: 97 Blazer, mystery coolant leak.

Keep on adding coolant to the rad when the engine is cold and has been sitting overnight.

If you go out in the morning and open the rad and you see that it is not up to the top, your rad cap is not sealing properly and you will need another one rated for 15 or 16psi.

I would check and see if the rad cap they put on is the proper one.

Do this every morning for a couple of days to force the air out of the system.
