Ford F-Series: ideal Engine Coolant for her Truck

In less complicated times, all a cooling system ever before needed to be a 50/50 mix of water and green antifreeze. Rinse and also repeat every pair of years and also you were good to go! In current years; however, new engine designs constructed with varying materials have seen manufacturers creating their own certain antifreeze coolant recipe to store these engines to run at top performance. Unfortunately, this has actually led to a many of perplexed consumers and also incorrect coolant mixtures being used.

This article applies to the Ford F-Series trucks (1948-Present).

In years past, selecting the correct antifreeze coolant for a Ford truck to be a fairly straightforward procedure as it was only a issue of deciding i beg your pardon brand that ethylene glycol come purchase, yet recent breakthroughs in coolant an innovation can currently make picking the finest coolant because that your certain F-Series Pickup a rather confusing ordeal. This confusion have the right to be further amplified if the coolant in her truck has been readjusted out at some allude and is not the same kind as outlined in the vehicle"s manual. Fortunately, Ford has detailed us through a encourage coolant intake chart and several coolant options that will job-related in all Ford F-Series trucks since their development in 1948 all the means up to their current year version vehicles.

Coolant Breakdown

Figure 1. A green coolant color typically indicates a timeless IAT antifreeze.

Ford trucks developed prior come 2001 come from the manufacturing facility filled with a traditional ethylene glycol antifreeze the has come to be known as not natural Additive technology (IAT) coolant. Frequently green in color, IAT coolant consists of silicates that offer the engine a high level of fast acting defense from corrosion, but generally last for only 2 years prior to corrosion security diminishes, hence requiring coolant instead of on a semi-regular basis. In general, this is a an excellent functioning coolant but has a reasonably short business life.

Organic Additive an innovation (OAT) coolant, frequently referred to a propylene glycol, was introduced around the revolve of the century as a much more "environmentally-friendly" coolant that featured extended business intervals compared to traditional IAT coolant. This is accomplished by removing the silicate compounds and replacing them v organic corrosion inhibitors ( such as carboxylate, sebacate, etc.) that room not chemically consumed over time. That said, OAT coolant can quickly breakdown if contaminated and also not sell the crucial engine defense required. Generally, these coolants should be replaced every 5 year or 150,000 miles.

Although plenty of other manufacturers made the switch directly from IAT to OAT coolants, Ford opted to use Hybrid necessary Additive modern technology (HOAT) coolant in their trucks between 2002-2010. As the name indicates, a HOAT coolant is a mixture draft to benefit from the long service life of one OAT coolant when providing good corrosion protection with a small dose of silicates added. This type of coolant is commonly known together a "Global" antifreeze through its G-05 designation, however the certain formula may vary slightly relying on the car manufacturer. Just like OAT coolant, HOAT antifreeze likewise has extended company intervals and also protects versus electrochemical degradation of cooling system components.

Scheduled Maintenance

The adhering to are general replacement intervals for the various species of coolant; however, refer to your owner"s manual and the coolant specifications for service intervals applicable to your vehicle.IAT (Green) - Every two years or 48,000 mile (Ford Spec ESE-M97B44-A)OAT (Orange) - five years or 150,000 mile (WSS-M97B44-D)HOAT (Yellow/Gold) - five years or 150,000 mile (Ford Spec WSS-M97B51-A1)

Common Questions

How perform I know which antifreeze coolant walk in mine truck?

Generally speaking, trucks built prior come 2002 will use eco-friendly IAT coolant. 2002 come 2010 models were factory filled with yellow HOAT coolant vice versa, 2011+ F-Series trucks are using orange OAT coolant. That said, always examine what coolant is in your auto prior to replacing it together it may have actually been adjusted at some suggest to something various than the manufacturing facility fill. See figure 4. Because that Ford encourage coolants based on your truck"s version year.

Figure 4. Coolant recommendations based upon model yearDo I need to use "Motorcraft" brand coolant?

No. Any brand of coolant the meets Ford coolant specifications (typically found on the earlier label) because that your details vehicle will certainly be suitable. The said, if you have actually a more recent truck the is quiet under warranty, the is very recommended the Motorcraft coolant be used in bespeak to fulfill warranty requirements.

Can ns mix different types of coolant?

Coolant species should never be mixed, specifically IAT and OAT coolant formulas as it will cause a chemistry reaction that basically turns the coolant into sludge and also can allow the engine to overheat and also damage cooling mechanism components. If accidentally mixed, the cooling system should be flushed and filled with the appropriate coolant.

Can I usage a different kind of coolant 보다 what is argued for mine vehicle?

If the car originally used environment-friendly IAT coolant, the is recommended the the very same formula continue to be provided as more recent OAT-based commodities will not carry out the same level or corrosion security for some of the older materials used in the cooling system. Conversely, the is not uncommon to see newer vehicles having been switched back to IAT coolant without any kind of ill-effects, however the service interval will be considerably shorter than with an OAT/HOAT formula.
