Coolant System Pressure Tester and Use 

I had a ‘69 Chevelle back in the day. The one of the adapters would fit, I do believe.

From where? Check you manual, there is a limit to pressure you should apply. But all hoses should hold.

@@StanleysGarage369 when I release the pressure after the test I get a load of coolant shooting up around where the radiator fill port

@@voidvincent Idle til it comes up to temperature, squeeze all the hoses with the rad cap off and overflow cap off…hoping that gets out all air pockets/bubbles. Then drive it and monitor engine temp.

If you need; I can send you a step-by-step video. Also, you can kinda see one being used in “ water in signal..” video.

@@StanleysGarage369 I already found it somewhere else. Thanks

I mean seriously? This is a pretty basic tool with a very simple process to use. Maybe fixing cars isn't for you.
