Now... say you suspect you've a coolant leak. With the proper adapter... couldn't one screw the cap onto the coolant reservoir... pump it up to whichever pressure... and watch the gauge to see if there's any pressure loss/leak?

Thank you.
First of all, you should NEVER pressurize your braking system to 25 PSIG with the Motive tool, 12-15 PSIG is plenty. The plastic brake reservoir tank and seals were never designed to hold that kind of pressure.

Second, Stant makes an excellent coolant pressure testing system with all of the necessary adaptors to fit just about anything on the street.
