Coolant pH Acidity and Heater Core Pinhole Leak San Antonio Fix

Coolant pH acidity occurs when old glycol degrades into formic and glycolic acids, dropping pH levels from 9.0 to below 6.0. In San Antonio’s extreme heat, this acidic fluid turns the cooling system into a battery, generating 0.30 V to 0.80 V of electrolysis. This chemical voltage pulls ions from aluminum walls, creating heater core […]
