2006 Daihatsu Terios Coolant — what it does and how to look after it

Coolant is absolutely relevant and used on the 2006 Daihatsu Terios. Technical sources including the Daihatsu Terios J200/J210 workshop manual (Cooling System section), the 3SZ‑VE engine specifications, and Daihatsu/Toyota Genuine Super Long Life Coolant documentation all specify a liquid-cooled system using ethylene glycol-based coolant. Owner’s manuals for this model family further highlight coolant checks and replacement as part of scheduled servicing.

The 2006 Terios relies on coolant to do four key jobs: carry heat away from the engine to stop overheating, raise the boiling point and lower the freezing point of the mix, protect alloy components inside the block and radiator from corrosion, and lubricate the water pump seal. Without a healthy 50/50 mix (or a factory premix), the 3SZ‑VE engine can run hot, suffer internal corrosion, or wear out the pump and thermostat early.

For this model, a high-quality ethylene glycol coolant designed for Asian vehicles is recommended. Many Terios examples use pink Toyota/Daihatsu Super Long Life Coolant (pre-mixed, phosphate OAT). If the vehicle has pink coolant, stick with the same type and don’t mix colours or chemistries. If it’s running a conventional green concentrate, it should be mixed 50/50 with demineralised water. Always check the owner’s/service manual and any under‑bonnet stickers for the correct spec.

Service intervals vary by coolant type. With pink Super Long Life Coolant, many schedules allow a long initial interval (up to around 160,000 km or 10 years) then about every 80,000 km or 5 years. Conventional green coolant is typically replaced more often (about every 2–4 years or 40,000–60,000 km). In harsh conditions, or if the mix looks rusty, cloudy, or weak on a refractometer/hydrometer, bring it forward. During any cooling system service, also inspect the radiator cap, hoses, clamps, thermostat, and water pump weep hole.

1. Start with a cold engine. Open the radiator drain and the reservoir, catch the old fluid, and dispose of it responsibly.
2. Flush with demineralised water until it runs clear (especially if changing coolant type).
3. Refill slowly with the correct coolant (or 50/50 mix if using concentrate). Set the heater to HOT to open the heater core.
4. Bleed air by idling with the cap off until the thermostat opens, squeeze the upper hose to purge bubbles. Top up the radiator and fill the overflow to “FULL”.
5. Fit the cap, road test, then recheck levels once cooled. Top up as needed.

Never use plain tap water, avoid mixing coolant chemistries, and keep pets away—coolant is toxic. A well-maintained cooling system keeps the Terios happy on long Kiwi and Aussie drives, towing, and city stop‑start alike.

• Popular questions about 2006 Daihatsu Terios coolant

What coolant should a 2006 Terios use?
This model is designed for ethylene glycol coolant suited to Asian vehicles. If it has pink Toyota/Daihatsu Super Long Life Coolant, keep using that exact chemistry. Otherwise, choose a quality silicate‑free, phosphate‑enhanced OAT/POAT coolant and mix it 50/50 with demineralised water if it’s a concentrate.

Avoid mixing colours or types—if changing chemistry, do a thorough flush first.

How often should the coolant be changed?
With pink Super Long Life Coolant, many schedules allow a long first interval (up to ~160,000 km or 10 years) and then about every 80,000 km or 5 years. If the vehicle uses conventional green coolant, plan on every 2–4 years or 40,000–60,000 km.

Always go by the owner’s manual and how the vehicle is used—towing, hot climates, or city idling can justify shorter intervals.

How much coolant does it take?
The system typically holds around five litres, but the exact amount depends on how thoroughly it’s drained and flushed. Measure what comes out and be prepared with extra premix to complete the bleed and top‑up.

After the first drive and cool‑down, recheck the radiator and overflow bottle and top up to the marks.
