Ford Ranger: 2.0 EcoBlue bi-turbo wet timing belt and oil pump belt breakdown - oil starvation

The 2.0 litre EcoBlue bi-turbo fitted to the Ranger from 2018 runs its oil pump on a rubber belt that sits inside the engine, bathed in hot engine oil, and the timing belt is a wet-running design as well. As the rubber ages in hot oil it sheds fine particles, and those particles collect in the oil pickup strainer until the pump can no longer draw oil - the engine then loses oil pressure and destroys its own bearings, usually with no warning beyond a knock and an oil light that comes on far too late. Ford cut the published belt interval from ten years or 240,000 km to six years or 160,000 km, and NZ workshops that specialise in these engines commonly advise doing it sooner than that on a ute that tows or works. The belt job in New Zealand runs roughly $2,600 to $3,400 including GST, which is a lot of money, but it is a fraction of what a seized engine costs. Any 2.0 bi-turbo Ranger with no wet belt receipt should be assumed to still be on its original belt.

• Oil pressure warning light flickering or coming on, especially at idle after a hot run
• Deep knocking or rattling from the bottom of the engine, worst when hot
• Engine oil that looks unusually dirty or has a gritty feel between the fingers
• Ticking or rattle for a few seconds on start-up as oil is slow to reach the top of the engine
• Rough running or an unexplained loss of power before a failure

1. 1

   Ask the seller whether the wet belt has been replaced and ask to see the invoice - this is the single most important piece of paper on a 2.0 bi-turbo Ranger and it should name the oil pump belt as well as the timing belt.

2. 2

   Check the odometer and the build year against Ford's six year or 160,000 km limit and work out whether it is already overdue.

3. 3

   Go through the service book looking at whether the engine oil has been changed on time and with the correct specification oil, because long oil intervals are what kill these belts.

4. 4

   Open the oil filler cap and look at the underside and down into the engine with your phone torch for tar-like black varnish or a gritty sludge rather than clean brown oil.

5. 5

   Check the dipstick for oil level and for a gritty feel between your fingers.

6. 6

   Start the engine from cold and listen for a rattle in the first few seconds and for any knock once it is warm, and watch that the oil pressure light goes out immediately.

7. 7

   Treat any oil pressure warning the seller mentions as a reason to walk away.

8. 8

   If a workshop inspection is possible: have a specialist inspect the oil pickup strainer and belt condition, and request an oil analysis for rubber and bearing material.

Parts involved: Timing belt, Turbocharger.

$2,600 to $14,000 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

• “Has the wet timing belt and oil pump belt been replaced, and do you have the invoice?”
• “What oil is used and how often is it changed?”
• “Has the oil pressure light ever come on, even briefly?”
• “Has this ute towed or carried heavy loads regularly?”
