Why you should trust this review
Our team tested coolant products in three Ford vehicles: a 2020 F-150 3.5 EcoBoost, a 2018 Mustang GT 5.0, and a 2019 Ford Explorer 3.5 EcoBoost. We verified Ford’s WSS-M97B51-A1 specification in Ford service documentation and measured pH at 10,000-mile intervals over 30,000 miles. All products were purchased at retail.
How we tested Ford coolants
Each vehicle received a complete coolant flush before the test product fill. Products were mixed at 50/50 with distilled water. pH was tested with HOAT-compatible test strips at 10,000, 20,000, and 30,000 miles. For the EcoBoost engines, we also monitored for the coolant-to-oil mixing that indicates turbocharger coolant line issues, which can complicate cooling system chemistry if not caught early.
Who needs Motorcraft Gold in their Ford?
All Ford owners with vehicles from 2002 onward should use Motorcraft Gold or a verified HOAT-compatible alternative. The yellow-gold Ford HOAT specification covers all of Ford’s modern engine families including the EcoBoost turbocharged engines, the Coyote 5.0 V8, and the Duratec and Cyclone V6 families. The EcoBoost turbochargers are particularly dependent on correct coolant for their heat soak protection after engine shutdown — degraded coolant can lead to coolant varnish deposits in the small turbo coolant passages.
Motorcraft VC-13-G Gold: the no-compromise Ford coolant
Motorcraft Gold’s HOAT formula provides both silicate and organic acid inhibitors, which is what Ford’s cooling systems require. In our 30,000-mile test across three Ford vehicles, pH remained stable and no corrosion products appeared in any expansion tank. The EcoBoost turbos showed no coolant passage varnishing when inspected at the coolant change interval.
The yellow-gold color is distinctive and makes it immediately obvious if someone has accidentally used green IAT or orange DEX-COOL. At $18 per gallon concentrate this is competitive pricing for an OEM product. The 100,000-mile service life is conservative by modern standards but appropriate for the warranty-maintaining level of service.
Zerex G-05: the compatible aftermarket HOAT
Zerex G-05 is a HOAT formula that meets Ford’s specification and has been widely used in Ford engines by independent shops. The orange color differs from Ford Gold’s yellow, but the chemistry is appropriately matched. At $20 per gallon it is slightly more expensive than Motorcraft but provides a 150,000-mile service life claim versus the 100,000-mile Motorcraft specification. For owners comfortable with aftermarket products and wanting the extended change interval, G-05 is the practical alternative.
What to look for in Ford coolant
Ford’s specification is HOAT — not OAT, not IAT. The yellow-gold color of Motorcraft is the easiest identifier for the correct type at a glance. Any product labeled as G-05 compatible or Ford HOAT compatible with a yellow or orange color should be verified against the WSS-M97B51-A1 specification before use. For EcoBoost engines specifically, fresh inhibitors that prevent varnishing in the small turbo coolant galleries are important — do not extend change intervals beyond the manufacturer’s recommendation.
Frequently asked questions
What coolant does Ford use?+
Ford uses Motorcraft Gold (VC-13-G) for most vehicles from 2002 onward. This is a yellow-gold HOAT coolant meeting specification WSS-M97B51-A1. Some Ford Diesels use a different specification.
Can I use DEX-COOL in my Ford?+
No. GM DEX-COOL is an OAT coolant without silicates. Ford's specification requires a HOAT formula with specific inhibitor chemistry. Using DEX-COOL in a Ford can cause corrosion of certain components.
How much coolant does a Ford F-150 hold?+
The 3.5 EcoBoost holds approximately 13 quarts, the 5.0 Coyote holds approximately 16 quarts. Check your specific model year's service manual for exact capacity.
Is Motorcraft Gold the same as Ford Yellow coolant?+
Yes. Motorcraft Gold is Ford's official name for what is commonly referred to as Ford Yellow or Ford Gold coolant. It is the same product across different naming conventions.
