Parts for your 2017 Toyota Wish-Oil pump

2017 Toyota Wish oil-pump: what it does and when to sort it

Yes, the 2017 Toyota Wish does use an oil-pump. Technical references that confirm this include the Toyota Electronic Parts Catalogue (for ZGE2# Wish models with 2ZR-FAE/2ZR-FE and 3ZR-FAE engines, which list an “Oil Pump Assy”), the Toyota Repair Manual for ZR-series engines (Lubrication section describing a crankshaft-driven trochoid pump integrated with the timing chain cover), and OE supplier catalogues (Aisin lists compatible oil-pumps for these ZR engines). So, an oil-pump is absolutely relevant on a 2017 Toyota Wish.

On this model, the oil-pump’s job is to circulate engine oil under pressure to bearings, camshafts, the timing chain tensioner and variable valve timing gear. It’s a compact internal-gear (trochoid) pump driven directly by the crankshaft and typically housed in the front cover. A pressure relief valve inside the assembly keeps oil pressure in the sweet spot, while a pickup and strainer in the sump feed the pump. Without it, metal-on-metal contact would occur in seconds — not ideal for a daily-driver people-mover.

For servicing, the pump itself isn’t a scheduled replacement item. The best way to keep it healthy is to stick to regular oil and filter changes (around every 10,000 km or 12 months in AU/NZ conditions), use the correct grade (commonly 0W-20 or 5W-30 depending on climate and engine variant), and keep an eye on leaks. Sludge is the enemy — good oil and timely changes protect the pump, the pickup strainer and the pressure control valve.

Replacement or deeper inspection becomes sensible if there’s low oil pressure, a persistent oil pressure warning light, noisy cold starts that don’t resolve quickly, metallic ticking under the bonnet, or timing-related rattle that points to a starving chain tensioner. If the front cover is coming off anyway (say, for timing chain work or a seal leak), many workshops will check clearances and consider a new pump, pickup O-ring and front crank seal while they’re there.

When fitting a new oil-pump on a 2017 Toyota Wish, a few best-practice notes help:

• Use quality parts (genuine or OE-equivalent like Aisin) and fresh sealant where the manual specifies FIPG on the cover.
• Replace the pickup O-ring/gasket and clean the strainer.
• Prime the pump with clean oil before first start and follow factory torque specs.
• After refilling, verify pressure quickly and check for leaks around the front cover and sump.

Done right, the oil-pump should be a fit-and-forget component for many years and kilometres.

Popular questions about 2017 Toyota Wish oil-pump

Which engine is in a 2017 Toyota Wish, and does that change the oil-pump?
The 2017 Wish commonly runs the 1.8-litre 2ZR-FAE (some markets also see the 2.0-litre 3ZR-FAE). Both use a crank-driven trochoid oil-pump integrated with the front cover. While the function is the same, part specifics can vary, so it’s smart to check the VIN/engine code before ordering parts.

What are the signs the oil-pump or lubrication system needs attention?
Warnings include the oil pressure light lingering or popping on, rattly starts, metallic ticking, VVT-related performance issues, and engine temperature creeping up due to extra friction. If any of these show up, park it and get a pressure test done — driving on low pressure can toast bearings in short order.

How much does an oil-pump replacement cost in Australia or New Zealand?
It varies with labour time and what else is done at the same time. As a rough guide, parts might run AUD/NZD $250–$600, with 6–10 hours of labour depending on workshop and what’s being resealed. All up, it’s often in the AUD/NZD $1,200–$2,500 range. Combining it with timing chain or front cover work can save duplicated labour.
