Re: Heater Core Replacement
Also, if you have a core rebuilt, either have shop show you it's good with pressure test or test it yourself. I had one "refurbished" and decided to check before installing...glad I did, it leaked at the tube joint when I applied pressure. It has been awhile (a few years), believe I used 10 to 12psi to check but not sure. Reading online it seems the system runs around 14psi.
Would be a major bummer to reinstall then discover it leaks.
