Hey all, what do you use to pressure test your cooling system? I've found several on Amazon but unsure if the adapter caps will fit. Anyone have a recommendation on brand of pressure tester and adapter cap needed? Also, what pressure do we need to test the system up to; 20psi? 30psi?

TIA!

 

You should be able to rent one from an auto parts store, and the kit comes with several adapters.

 

I’m looking to buy a tester, If anyone has a kit they’d recommend, I’d appreciate the brand and part number(s).

 

I got a Mityvac MV4560 coolant system tester from amazon. not too expensive and the adapters fit perfectly. It also would fit on my other vehicles too.

 

fwiw, the stock cap is a 15 lbs pressure release.
