Parts for your 2006 Ford Falcon-Coolant

2006 Ford Falcon coolant

Coolant is absolutely relevant and used on the 2006 Ford Falcon. Ford’s own technical literature for the BA/BF series — including the 2006 BF Falcon Owner’s Manual and the BA/BF Workshop Manual — specifies a pressurised liquid cooling system that runs an ethylene‑glycol based, corrosion‑inhibited coolant. The manuals call for Ford‑approved coolant meeting specification WSS‑M97B44‑D (commonly supplied as Motorcraft Premium Engine Coolant in Australia/NZ), mixed with demineralised water. This aligns with Australian “Type A” glycol coolant requirements for alloy head/iron block engines.

On a 2006 Falcon, coolant isn’t just about stopping overheating. It also stabilises engine temperature, raises the boiling point under pressure, protects aluminium and cast‑iron surfaces from corrosion, helps prevent cavitation around the water pump, and provides freeze protection for alpine trips. That matters on the Barra inline‑six and Boss V8 alike, where thermal control and corrosion protection keep head gaskets, heater cores and radiators happy for the long haul.

For routine servicing, a Falcon of this vintage benefits from regular coolant checks and periodic replacement per the Ford service schedule shown in the owner’s book. Ford specifies a long‑life, glycol coolant, stick to the same chemistry and spec — don’t mix green hybrid coolants with later orange OAT types used on different models. If unsure, drain and refill with a known, correct product that states compliance with Ford WSS‑M97B44‑D and AS 2108 Type A.

• Check the level only when cold, at the translucent expansion tank. Top up with the same premix, or 50/50 concentrate with demineralised water.
• Inspect colour and clarity. Milky, rusty or oily coolant points to issues that need attention.
• Pressure‑test the cap and system during major services, weak caps cause boil‑over and loss.
• When replacing, drain fully, flush with demineralised water, then refill slowly. Set the heater to HOT, run the engine to operating temp, and bleed air via the reservoir. Recheck the level once cooled.
• Watch common leak points: radiator end tanks, heater core, water pump, thermostat housing and the expansion tank itself.

Following Ford’s specs — as laid out in the 2006 BF Falcon Owner’s Manual and BA/BF Workshop Manual — keeps temperatures stable, corrosion at bay, and saves expensive cooling system repairs later.

Popular questions

What coolant type does a 2006 Ford Falcon use?
Ford specifies a Type A, ethylene‑glycol based coolant that meets Ford WSS‑M97B44‑D (often sold as Motorcraft Premium Engine Coolant). Use it premixed or as a 50/50 blend with demineralised water. Sticking to this spec maintains corrosion protection for the alloy head and ensures correct boiling and freezing protection.

How often should the coolant be changed on a 2006 Falcon?
The service schedule in the owner’s book lists periodic coolant renewal as a major service item for BA/BF Falcons. Many long‑life fills are due at extended intervals, but time matters as much as kilometres. If the history’s unknown, it’s smart to replace the coolant now and then follow the specified interval thereafter.

How do you bleed the BA/BF Falcon cooling system after a coolant change?
Fill slowly at the expansion tank, set the heater to HOT, and start the engine. Let it reach operating temperature so the thermostat opens, then top up as the level stabilises. Lightly squeeze the upper hose to purge trapped air. Once cooled, recheck the level and inspect for leaks. A healthy radiator cap is essential for proper bleeding and pressure.
