I spoke to a guy today who mentioned I should get my antifreeze tested for acid content. He said the acid damages the injecter liners and allows antifreeze into the oil. I'm not familiar with this.But I certainly don't mind getting it done. Any suggestions or comments are welcome.
HTRD,
While checking the pH is certainly one of the steps in testing your coolant, you per se` arent checking for
acid, rather you are checking the SCA level. The SCA level is a gauge of how much "secret additive" is still left in your coolant. The additive lays down a protective coating on the coolant system walls. No matter what, you have cavitation going on inside your system and this protective barrier that gets laid down is what
cavitates off instead of your cylinder walls, which left unprotected long enough will lead to pinholes.
Get a test kit from either your Ford dealer or nearly any big truck shop and test it yourself. Its as simply as warm up engine, dip and compare colors. DCA-4 is what you want to add if you have a low reading. Vinegar can be added if pH levels are elevated.
Hope that helps clear some confusion.
