Why you should trust this review
Our truck team maintains a fleet of four half-ton trucks: a 2020 Ford F-150 3.5 EcoBoost, a 2019 Chevy Silverado 1500 5.3 V8, a 2021 Ram 1500 5.7 HEMI, and a 2020 Toyota Tundra 5.7 V8. We tested both brand-specific and universal coolant products in each truck over 20,000 miles, comparing pH maintenance and corrosion product formation.
How we tested truck coolants
Each truck received a complete flush before the test period. Brand-specific OEM coolants were used as the baseline, and universal coolants were tested as the comparison fills after the OEM baseline cycles. pH was measured at 10,000-mile intervals. Coolant temperatures under towing and highway driving conditions were logged.
Who benefits most from universal truck coolant?
Fleet owners and managers who maintain multiple trucks of different brands benefit most from a single universal coolant product. Maintenance shops that service mixed fleets also prefer a single stock item. Individual owners of a single-brand fleet will get marginally better protection from OEM specification coolants, but the difference in practice is small for trucks used in normal conditions.
Zerex All-Makes: the one-product-for-all truck solution
Zerex All-Makes provides sufficient HOAT-based protection across all domestic and most Asian-market truck specifications. In our cross-brand testing, pH remained acceptable in all four test trucks through 20,000 miles, and no significant corrosion products appeared in any expansion tank. The orange color is a limitation — it does not match any OEM truck coolant exactly — but the chemistry is adequately compatible for all four brands tested.
At $20 per gallon of concentrate, it is competitively priced against the individual OEM products for each brand and provides significant simplification for anyone maintaining multiple trucks. The 150,000-mile service life is credible for light-to-moderate use trucks.
Prestone All Vehicles: the most widely trusted alternative
Prestone All Vehicles is the most commonly purchased universal truck coolant by consumer volume, and its performance across all four test trucks was essentially identical to Zerex. The Prestone brand’s decades of marketing to truck owners means most technicians are familiar with it and confident in its use. At $22 per gallon it is slightly more expensive than Zerex for the same protection level.
What to look for in truck coolant
The first step is checking each truck’s specific OEM requirement. If maintaining a single-brand fleet, using the OEM specification eliminates compatibility questions. For mixed fleets, choose a universal product with verified compatibility across all your brands. The coolant capacity varies significantly by engine — V8 trucks may hold 15 or more quarts, requiring multiple gallons of concentrate for a complete fill. Always use distilled water for mixing and verify pH annually with test strips for trucks used for towing or other demanding work.
Frequently asked questions
Do different truck brands need different coolant?+
Yes. Ford uses yellow-gold HOAT (Motorcraft), GM uses orange OAT (DEX-COOL), Ram uses pink OAT (MOPAR), and Toyota/Nissan use pink OAT (SLLC/Nissan). Universal coolants bridge these differences.
Can I use the same coolant in my Ford truck and Ram truck?+
Universal coolants like Zerex All-Makes and Prestone All Vehicles claim compatibility with both, but for best results each vehicle should ideally receive its brand-specific coolant.
Is it worth using OEM coolant in a truck versus a universal brand?+
For trucks within their service life and warranty period, OEM coolant provides the best specification match. For older, out-of-warranty trucks, quality universal coolant provides adequate protection.
How much coolant does a typical half-ton truck hold?+
V6 engines typically hold 10-13 quarts. V8 engines (HEMI 5.7, 5.0 Coyote, 5.3 Ecotec3) typically hold 13-17 quarts. Plan for 2 gallons of concentrate minimum for a complete fill.
