but from what I understand, now that you have put some in, you need to either monitor the SCA's with the test strips, or change your coolant.

yes you can have too much of the additive. Yes you have contaminated the yellow coolant and will either have to flush and replace with yellow, or begin monitoring coolant with test strips. Your additive is not compatible with yellow coolant additive, they will neutralize each other. Yellow coolant protects diesels against cavitation by different methods. Go to zerex site for more information.

The yellow coolant is an hybrid organic acid coolant (low pH) and the SCA additive alters it's chemistry. So obviously if you add the SCA to an acid coolant, you are going to alter the pH. From what I understand, it can cause sludges to furm in your coolant as well as affect the anti-cavitation properties of the coolant.
