GWM Ora — Fluids, Capacities & Specifications
This is the first GWM model whose fluid data we can publish from primary documents — the official UK owner’s manual and service booklet, both archived. An EV still has real fluids: a reduction-gearbox oil (Castrol BOT 352 B1, replaced at 30,000 miles), two separate coolant circuits on a 4-year/48,000-mile change cycle, and DOT4 brake fluid replaced at every scheduled service. And one specification we’ve never seen documented before: the powertrain coolant capacity differs between left- and right-hand-drive cars.
Fluids — official specifications and change rhythms
| Item | Specification | Capacity | Official change rhythm (UK) |
|---|---|---|---|
| e-Transaxle (gearbox) oil | Castrol BOT 352 B1 (BEV) | 0.74±0.02 L | Replace at 30,000 miles |
| Powertrain coolant | Ethylene glycol 35 | 6.7±0.2 L (RHD) · 6.5±0.2 L (LHD) | ≤4 years / 48,000 miles |
| Heating/A-C circuit coolant | Ethylene glycol 35 | 2.1±0.2 L | ≤4 years / 48,000 miles |
| Brake fluid | DOT4 synthetic | 0.72±0.1 L | Replaced at every scheduled service per the UK schedule |
| Washer fluid | quality screen wash | 2.3±0.2 L | top up; never substitute soapy water (paint damage — manual’s own warning) |
Sources: official Ora 03 owner’s manual, UK edition (Oil and fluid parameters, p. 252; archived with checksum) and the official UK Service & Warranty booklet (change intervals). The manual instructs that coolant replacement is an authorised-service-centre job — the circuits interact with high-voltage battery cooling, and this is not DIY territory.
Two batteries, two chemistries — know which you have
| Version | Battery model | Chemistry | Rated |
|---|---|---|---|
| Standard Range | PB365131A | LFP (lithium iron phosphate) | 364.8 V / 131 Ah ≈ 48 kWh |
| Extended Range | PE338187A | NMC (ternary lithium) | 337.64 V / 187 Ah ≈ 63 kWh |
Same source (p. 250). Motor on both: TZ153XS001 permanent-magnet synchronous, 126 kW / 250 Nm. Why chemistry matters to you: LFP packs are routinely charged to 100%; NMC packs live longer capped at ~80–90% for daily use — the right charging habit depends on which badge-invisible battery your Ora carries. Charging window: −20 to 55 °C (the car manages this; park cool in heatwaves).
Workshop data the independents will thank us for
| Brake pad minimum thickness | 2 mm front and rear (friction material) |
| Brake disc minimum thickness | 20 mm front · 10 mm rear |
| Brake pedal free play | 4–7 mm |
| Tyres | 205/55 R17 95W · 215/50 R18 96V/92W |
| Snow chains | front wheels only, ≤12 mm steel (≤15 mm TPU) |
Official wear limits from the manual — rare, publishable, and exactly what an EV that regenerates most of its braking needs checked: discs on low-regen-wear cars corrode before they wear, so the limit plus a visual rust check beats mileage rules.
UK ownership notes
UK warranty: 5 years/unlimited miles plus 12-year anti-corrosion (per the archived booklet). The Ora 03 left the UK market in April 2026 — service obligations continue; this page is part of keeping the orphaned fleet well-documented. Australian owners: the $99 program story is on the schedule page.
