Parts for your 2013 Ford Ranger-Coolant

2013 Ford Ranger coolant — what it does and how to look after it

Coolant absolutely is used on the 2013 Ford Ranger. Ford’s technical publications (PX Ranger Owner’s Manual, 2012–2015) and Motorcraft service data specify a liquid-cooled system on the 2.2L and 3.2L Duratorq engines, requiring an ethylene‑glycol, Organic Acid Technology (OAT) coolant that meets Ford spec WSS‑M97B44‑D (commonly the Motorcraft Orange formulation). So it’s very much a must‑have fluid for this ute.

The coolant’s job is to carry heat away from the engine to the radiator, stopping boil‑over on stinking hot days and preventing freezing in alpine conditions. Just as importantly, it protects alloy components from corrosion, stops scale building up in the passages, and reduces cavitation wear in the water pump. A correct 50/50 mix with demineralised water lifts boiling protection, lowers freezing point, and keeps the chemistry stable for long service life.

For servicing, a quick glance at the expansion tank when cold should show the level between MIN and MAX. Top up only with premix that meets Ford WSS‑M97B44‑D, ideally the same orange OAT already in the system. Avoid mixing different coolant chemistries or colours. If the level keeps dropping, look for damp hose ends, a sweet smell, or pink/orange crust around joins and the water pump. Heater going weak or the temp gauge acting odd can also hint at trapped air or low coolant.

Ford specifies long‑life intervals with the factory OAT fill: typically up to 10 years or around 200,000 km for the first change, then every 5 years or 100,000 km thereafter. Heavy towing, outback corrugations, or contaminated water can shorten that. For a change, let the engine cool, drain the radiator (and block if accessible), flush with demineralised water until clear, then refill with a 50/50 mix that meets the Ford spec. Run the engine with the heater on to purge air, squeeze the upper hose to help burp bubbles, and recheck the level after a few heat cycles.

Handy checks during coolant service include inspecting hoses and clamps, the radiator cap seal, and belt/pulley condition. A simple refractometer or test strips can confirm concentration and inhibitor health between major services.

• Watch for low level, sweet smells, dried orange residue, overheating, or weak cabin heat.
• Never mix orange OAT with other types, fully flush if the coolant type is unknown.
• Use only demineralised water for mixing to avoid scale and deposits.

Popular questions about 2013 Ford Ranger coolant

What coolant type and colour does a 2013 Ranger use?
Ford specifies an OAT ethylene‑glycol coolant meeting WSS‑M97B44‑D, typically Motorcraft Orange. If a workshop has converted the system to Ford’s later yellow spec, the system should have been fully flushed first—don’t mix orange and yellow.

How often should the coolant be changed?
With the original long‑life fill, plan for up to 10 years or about 200,000 km, then every 5 years or 100,000 km. Check level and condition at every service and top up only with the correct premix.

What capacity and mix ratio should be used?
Expect roughly 10–12 litres depending on engine and options. A 50/50 mix of approved concentrate and demineralised water is the sweet spot for corrosion protection and temperature extremes. Don’t exceed about 60% concentrate.
