ZEREX G48 HOAT Antifreeze Coolant
This pre-diluted 50/50 coolant uses an ethylene glycol base with a HOAT formulation in the G48 series. It is coloured blue and carries a 7.1 pH rating. The product is designed for engine cooling systems that specify a phosphate-free, silicate-containing fluid. It is sold as a single one-gallon bottle.
Ready-to-use 50/50 concentration
The fluid arrives already mixed to a 50/50 ratio, so no distilled water or measuring is required before filling the system. This saves time during a flush-and-fill job and reduces the risk of an incorrect mixture. The bottle contains exactly one gallon of the finished coolant. No additional additives or supplements are included in the package.
Service interval limits and chemical constraints
The fluid is rated for five years or 150,000 miles of service before a change is recommended. Freeze protection extends to -34 degrees F and the boiling point reaches 265 degrees F under system pressure. The formulation is not biodegradable and contains silicate, so it must not be used in systems that require a silicate-free OAT coolant.

Questions about this item
How often will the ZEREX G48 HOAT coolant need to be replaced?
The coolant carries a 5 yr lifetime rating and a 150, 000 mi mileage rating before replacement is recommended.
What temperature limit is reached first during continuous engine operation?
The boiling point is 265 Degrees F, so that limit will appear before the freezing point of -34 Degrees F under sustained heat.
How much heat and chemical load does the pre-diluted 50/50 ethylene glycol formula add to the cooling system?
The 50/50 pre-diluted ethylene glycol base with 7.1 pH is phosphate-free and contains silicate for corrosion protection while raising the boiling point to 265 Degrees F.
