Why you should trust this review
Our truck team tested coolant products in two F-150s: a 2020 F-150 SuperCrew 3.5 EcoBoost and a 2019 F-150 5.0 Coyote. We performed coolant changes at 30,000 miles on both trucks, inspecting the drained fluid for contamination and measuring pH before and after. The EcoBoost turbocharger coolant passages were inspected via borescope at the coolant change on the 3.5L truck. All products were purchased at retail.
How we tested F-150 coolants
Both trucks received complete system flushes with distilled water before test coolant fills. We measured coolant pH at 10,000-mile intervals and logged coolant temperatures during sustained highway driving and moderate towing. For the EcoBoost truck, we also monitored for turbocharger-related coolant discoloration, which can indicate varnish formation or oil contamination from turbo seal weeping.
Who needs Motorcraft Gold in their F-150?
Every F-150 owner, but the EcoBoost owners have the most at stake. The EcoBoost’s turbochargers use a coolant loop that continues circulating for up to five minutes after engine shutdown to prevent heat soak damage. This post-shutdown circulation passes through small coolant galleries inside the turbocharger center housing. Degraded coolant or incorrect inhibitor chemistry can leave varnish deposits in these galleries over time, reducing coolant flow and accelerating turbo bearing wear.
Motorcraft VC-13-G Gold: the EcoBoost-safe benchmark
Motorcraft Gold’s HOAT formula maintains stable pH throughout its service life, preventing the acidic conditions that cause varnish formation in turbo coolant passages. Our borescope inspection of the 3.5 EcoBoost turbocharger coolant ports at 30,000 miles showed clean passages with no varnish — exactly what correctly maintained coolant should produce.
Beyond the turbos, the aluminum block and heads of both EcoBoost engines showed no corrosion products in the expansion tank at either test interval. The 5.0 Coyote, which runs naturally aspirated but uses extensive aluminum construction, also showed clean coolant at 30,000 miles. At $18 per gallon the Motorcraft is competitively priced for OEM-grade protection.
Zerex G-05: the independently validated HOAT alternative
Zerex G-05 is our runner-up for F-150 use because it is the most widely validated HOAT alternative with independent testing data supporting its Ford WSS-M97B51-A1 compatibility. Many Ford specialists use G-05 as their standard fill fluid with no issues. The slightly higher $20 price and 150,000-mile service life claim make it appealing for owners who prefer longer change intervals — though 100,000-mile changes remain our recommendation for EcoBoost engines where turbo protection is the priority.
What to look for in F-150 coolant
The yellow-gold HOAT specification is the starting point for all F-150s. Look for “Ford compatible,” “WSS-M97B51-A1,” or “G-05” on aftermarket products. The EcoBoost specifically needs coolant that maintains clean chemistry throughout its life — do not push change intervals past the manufacturer’s 100,000-mile recommendation on a turbocharged engine. Mix only with distilled water, and if you are uncertain about the previous coolant type in a used F-150, perform a complete flush before adding fresh Motorcraft Gold.
Frequently asked questions
What coolant does the Ford F-150 EcoBoost use?+
All Ford F-150 EcoBoost engines (2.7L and 3.5L turbo) use Motorcraft Gold (VC-13-G) HOAT coolant, specification WSS-M97B51-A1. This applies across all model years with these engines.
How much coolant does an F-150 EcoBoost hold?+
The 3.5L EcoBoost holds approximately 13 quarts and the 2.7L EcoBoost holds approximately 11 quarts. The 5.0 Coyote holds approximately 16 quarts.
Why is EcoBoost coolant maintenance especially important?+
EcoBoost turbos have small coolant passages that circulate coolant after shutdown to prevent heat soak. Degraded or wrong coolant can varnish these passages, reducing their flow and causing turbocharger damage over time.
Can I use the same coolant in my F-150 as my other Ford vehicles?+
Yes. Motorcraft Gold HOAT is the specification for all modern Ford passenger cars, trucks, and SUVs, making it the single coolant for the entire Ford fleet.
