Parts for your 2013 Ford Escape-Thermostat

2013 Ford Escape thermostat — what it does and when to replace it

Drawing on the Ford Workshop Manual (Section 303-03 Engine Cooling) and Motorcraft parts catalogues, the 2013 Ford Escape is definitely fitted with a conventional, wax‑pellet thermostat across its 1.6L EcoBoost, 2.0L EcoBoost and 2.5L engines. It lives in a composite thermostat housing at the front of the engine and is a normal service item if faults arise.

The thermostat’s job is to get the engine up to operating temperature quickly, then hold it there by metering coolant flow to the radiator. That keeps fuel economy sharp, emissions tidy and the cabin heater nice and toasty. On the Escape’s EcoBoost engines, the thermostat is integrated into a plastic outlet housing with an O‑ring seal, and the cooling system uses a pressurised degas bottle, so bleeding air correctly after any work is essential.

While there’s no scheduled replacement interval in Ford service literature, age, heat cycles and coolant quality eventually take their toll. Telltale signs of a crook thermostat include slow warm‑up, temp gauge wandering, overheating at speed, fans roaring for no clear reason, patchy heater performance, or a check engine light with a P0128‑type code (coolant not reaching temperature).

• Best practice when replacing: start from a cold engine, safely depressurise the system via the degas bottle, and drain enough coolant to sit below the housing level.
• Use a quality replacement to OE spec, fit a fresh O‑ring, and clean mating faces. Don’t overtighten the plastic housing bolts.
• Refill with the Ford‑approved coolant specified for the vehicle, mixed with demineralised water if using concentrate. Avoid mixing coolant colours or chemistries.
• Bleed the system: heater on full hot, fan low, run the engine and top up as air purges. Check for leaks under the bonnet once cooled and recheck the level.

For owners clocking up big kilometres or operating in hot Aussie or Kiwi conditions, a pre‑emptive thermostat and housing refresh around the 8–10 year/160,000 km mark can be cheap insurance against overheating dramas. Regular cooling system checks during servicing—hoses, clamps, coolant condition and the degas bottle level—help the Escape stay on song.

Popular questions about 2013 Ford Escape thermostats

Where is the thermostat on a 2013 Ford Escape?
It’s mounted in the coolant outlet/thermostat housing at the front of the engine, where the upper radiator hose meets the engine. On the 1.6L and 2.0L EcoBoost, it’s an integrated plastic housing with an O‑ring, the 2.5L has a similar setup. Access is from the front under the bonnet with basic hand tools.

What symptoms point to a failing thermostat?
Common clues are slow warm‑up, fluctuating temperature readings, overheating under load or at highway speeds, weak cabin heat, cooling fans running more than usual, and fault codes such as P0128. Any of these warrant a cooling system check and likely thermostat replacement.

Do I need to bleed the cooling system after changing the thermostat?
Yes. The Escape uses a degas bottle system that traps air if not bled. Refill with the correct coolant, set the heater to full hot, run the engine, and top up as bubbles purge. Let it cool fully, recheck the level, and inspect for leaks.
