Parts for your 2013 Ford Transit-Thermostat housing

2013 Ford Transit Thermostat Housing

Yes, a thermostat housing is fitted to the 2013 Ford Transit. Ford’s workshop literature (Engine Cooling, Section 303‑03) shows an integrated thermostat and housing assembly on the 2.2 Duratorq TDCi engines used in this model year. The part is also catalogued by Motorcraft and common cooling system references from Autodata and Haynes for 2006–2013 Transits, confirming it’s a serviceable component on these vans.

What does it do? The thermostat housing holds the thermostat in place and routes coolant from the engine to the radiator and heater circuit. It helps the engine warm up briskly, then maintains a steady operating temperature so the Transit runs sweet as, delivers decent heater performance, keeps emissions tidy and fuel use in check, and prevents overheating under load.

Because most housings are moulded plastic with multiple hose connections and a seal or O‑ring, they can age and seep. Common tell‑tales include dried coolant crust around the housing or hose stubs, a slow coolant drop in the expansion tank, wavering temperature gauge, poor cabin heat, or a check engine light with a P0128 code. Left too long, a small weep can become a split, risking an overheat on a hot day or up a steep Kiwi pass.

Servicing advice: at each service interval, cast an eye over the housing and upper radiator hose area under the bonnet. Look for staining, hairline cracks, and perished hoses or clamps. If the thermostat is lazy or the housing is leaking, replace the assembly as a unit with a quality OE‑spec part. Always fit new seals, clean the mating surface, torque bolts to the workshop spec in a criss‑cross pattern, and refill with the correct Ford‑approved coolant mix. Bleed the system with the heater on hot and recheck the level after a cool‑down and a short drive. Many workshops in AU/NZ opt to replace the thermostat/housing preventatively around major cooling service milestones or timing belt/water pump work, especially on higher‑kilometre Transits used for towing or heavy loads.

• Check by VIN/engine code to get the correct housing variant (FWD vs RWD layouts differ).
• Never reuse flattened O‑rings, coolant leaks often start there.
• Dispose of old coolant responsibly, it’s toxic to pets and wildlife.

FAQs

Are all 2013 Ford Transit thermostat housings the same?
Not quite. The 2.2 Duratorq TDCi was built in different outputs and in FWD and RWD layouts, and the plumbing can vary. Always match by VIN and engine code so the hose connections, sensor ports and thermostat spec are correct for the van.

Where is the thermostat housing on a 2013 Transit?
It’s mounted at the front/side of the engine where the upper radiator hose meets the engine. On many 2.2 TDCi setups it sits near the alternator area, with multiple hose take‑offs and often an integrated coolant temperature sensor.

How is the cooling system bled after housing replacement?
Fill the expansion tank with the correct coolant mix, set the heater to full hot, and run the engine at a fast idle until the thermostat opens and the radiator hose warms. Top up as bubbles purge. Some engines have bleed points—follow the workshop procedure and recheck the level once the engine cools.
