Hey 1908,

I realize you were not asking me, but I can give you at least two caveats about using your cooling system pressure tester to supply the extra oomph you want to get those bleeders squirting. You may think they are insignificant worries compared to foot pedal bleeding, but I think maybe worth mentioning because I get to tell a story from experience.

Before I acquired the Motive product, I used a garden sprayer to supply air pressure to both cooling system and brake reservoir. The number one issue was how quickly you could empty the front or rear section of the reservoir and force air into the system! So easy to be watching the bubbles progress through the bleeding hose and forget how little the reservoir holds.

Yes, this is just a goof, but a hard lesson, because now I had to bleed all over again. With the Motive product, you don't put air into the reservoir, just brake fluid. You don't need to jump up every few minutes and check the rez.

Second issue you anticipated. Too much pressure could ruin your paint job. This one never happened to me, but even with 10psi you can see that plastic reservoir straining at the seams. I wrapped a ziptie around for safety. An explosion of brake fluid would not be fun.

Get a Motive. You can put the fluid in it.
