Symptom Finder: Known Weak Points
| What you see or hear | Check first |
|---|---|
| Van sits low at the rear or leans to one side | The rear leaf springs and their bushes. Leaf springs can settle on a van that works loaded, so compare the ride height side to side and order springs by side. |
| Rear tyres wearing quickly or unevenly | Tyre type and pressure. Make sure the tyres are 195/60 R16C commercial tyres with the correct load index, then set the pressures from the placard on the van. |
| Sliding side door stiff, noisy or closing unevenly | The door rollers and runner. Clean the runner, look for a worn or broken roller, and order the parts for the correct side. |
| Grinding or scraping from the brakes after the van has stood | Corrosion on the discs. Regenerative braking means the discs do less work, so rust can build up. Pitted discs need replacing with pads, ordered by axle. |
| Motor or battery temperature warning | The coolant level, the electric coolant pump and the temperature sensors. Trace which circuit is affected, then order the part by OE number. |
| Van charges on AC but not on a DC charger | The charge socket and its pins. Look for damage, dirt or heat marks, then order the socket by the OE number on the fitted unit. |
| Knock from the front over bumps | The MacPherson strut top mounts and the lower arm bushes. Check for play at each corner and order the parts by side. |

About BYD T3 Parts
The BYD T3 is a compact two-seat electric van, the all-electric version of the BYD M3. It was first shown at the 2015 Shanghai Auto Show, and it went mainly to fleet buyers in China, including delivery and postal firms. The body is 4,460 mm long, 1,720 mm wide and 1,875 mm high on a 2,725 mm wheelbase. A single electric motor drives through a single-speed transmission, fed by a battery under the load floor: 50.3 kWh in many Chinese-market vans. For parts, the van combines the drive, battery, cooling and climate hardware of an electric car with working-van running gear: MacPherson struts at the front, leaf springs at the rear, discs all round and 195/60 R16C commercial tyres. Every part here is listed by OE number, and the number on the old part is the surest check that a replacement fits.
What to know before buying BYD T3 parts
Start with the name on the tailgate, but do not order by it. Outside China the same van is also sold as the ETP3. The body, the 2,725 mm wheelbase and the running gear carry over, but the specification is not the same on every van, so the badge does not tell you which parts are fitted. Match every part by the OE number on the part you are replacing.
The battery is the biggest variable. Many Chinese-market vans use a 50.3 kWh nickel-cobalt-manganese battery, but not every van has this pack, and some use a lithium iron phosphate Blade battery instead. These are different packs, so battery modules, battery sensors, high-voltage fuses and charging parts must be matched to the pack actually in the van. Read the OE number on the unit you are removing before you order.
The drive varies too. Published outputs differ between versions, and published sources even disagree on which axle is driven. Order the motor, its controller and its mounts by OE number, and look underneath to see which axle carries the driveshafts before ordering hub, bearing or driveshaft parts.
The T3 shares its outside dimensions with the BYD M3. Parts for the T3's electric drive, battery and charging are specific to the T3, so do not take them from M3 listings. For body panels, glass and suspension, do not assume a match from appearance. Compare OE numbers first.
Body style matters behind the front seats. In China the T3 was built as a box van, a postal van and a small passenger version. Check the body and door layout before ordering rear panels, glass, door parts or cabin trim.
Finally, the running gear. The front track is 1,490 mm and the rear 1,533 mm, the front has MacPherson struts and the rear leaf springs, and both axles have disc brakes, so front and rear parts are never interchangeable. Order brakes and suspension by axle and side. Tyres are 195/60 R16C commercial tyres, so read the load index on the sidewall as well as the size. Where a listing is split by date, read the build date on the identification plate before ordering.
Before You Order: 8 Checks
- Do not order by the name on the tailgate, and match every part to the OE number on the part you are replacing.
- Check which battery is fitted before ordering battery, charging or high-voltage parts, since not every van has the same pack, then order by the pack's OE number.
- Look underneath to see which axle carries the driveshafts before ordering hub, bearing or driveshaft parts.
- Do not take drive, battery or charging parts from M3 listings, and check M3 body parts by OE number before ordering.
- Read the size and load index on the tyre sidewall, then order 195/60 R16C commercial tyres with at least the same load index.
- Order brake and suspension parts by axle and side, since the front and rear are built differently.
- Where a listing is split by date, read the build date on the identification plate before ordering.
- Order painted panels by the colour code on the van rather than by colour name.
Generations and Facelifts
The T3 is the all-electric version of the BYD M3, a compact van that shares its body size: 4,460 mm long and 1,720 mm wide on a 2,725 mm wheelbase. BYD first showed the T3 at the Shanghai Auto Show in 2015. In China it went mainly to fleet buyers rather than private owners, with DHL among the users, and BYD built it as a box van, a postal van and a small passenger version on the same body. Many Chinese-market vans use a 50.3 kWh nickel-cobalt-manganese battery.
Outside China it is also sold as the ETP3 in some markets. Under that name the body and running gear stayed the same, but the battery chemistry changed, and with it the pack and the parts that work with it.
The T3 has had no facelift, and no model-year update to the body or running gear has been reported. For parts, the dividing lines come from the battery rather than the styling. For battery, charging and high-voltage parts, match the OE number on the old unit. Where a listing is split by date, read the build date on the identification plate.
BYD T3 Parts: Frequently Asked Questions
How do I make sure a part fits my BYD T3?
Match the OE number. Every part on this site is listed under the OE number printed on the original part, and if the number on the part you are replacing matches the listing, the part fits. That check matters on the T3 because the same van has been sold under two names, with two different batteries and more than one body style, so the badge alone does not settle fitment. If the old part is missing or its number cannot be read, send a photo through the quote form and we will reply within 24 hours, usually sooner.
Which body styles was the T3 built in?
In China the T3 was built as a box van, a postal van and a small passenger version, all on the same body, 4,460 mm long and 1,720 mm wide on a 2,725 mm wheelbase. It went mainly to fleet buyers, including delivery and postal firms. Body style matters behind the front seats, so check the body and door layout of your van before ordering rear panels, glass, door parts or cabin trim. Then confirm each part by the OE number on the part you are replacing.
Do BYD M3 parts fit the T3?
Some may, but check every one. The T3 is the all-electric version of the M3 and shares its outside dimensions, 4,460 mm long and 1,720 mm wide on a 2,725 mm wheelbase. Its electric drive, battery and charging hardware are specific to the T3, so do not take those parts from M3 listings. For body panels, glass and suspension, a part that looks the same is not proof of fit. Compare the OE number on your old part with the listing before you order.
Which battery does my T3 have?
It depends on the van. Many Chinese-market vans use a 50.3 kWh nickel-cobalt-manganese battery, but not every van has this pack, and some use a lithium iron phosphate Blade battery instead. The two packs are not interchangeable, and parts that work with the battery, such as its sensors and high-voltage fuses, should be matched to the pack actually fitted. Read the OE number on the pack or on the part you are removing, and order to that number rather than to a brochure.
Is the T3 front-wheel or rear-wheel drive?
Published sources disagree, and listings for different versions describe the drive differently, so do not rely on a description. A single motor drives through a single-speed transmission. The quickest way to settle it is to look underneath: the driven axle is the one with driveshafts running from the motor to the wheels. Once you know, order hubs, bearings and driveshafts for that axle by side, and confirm the motor, controller and mounts by the OE number on the old part.
Is the motor the same on every T3?
No. A single motor drives through a single-speed transmission, but published outputs differ between versions of the T3, so motors and their controllers should not be ordered on the model name alone. Read the OE number on the motor or controller you are replacing and match it to the listing. If the plate on the unit is damaged or hard to read, send a photo through the quote form and we will reply within 24 hours, usually sooner.
What tyres does the T3 use?
The T3 runs 195/60 R16C tyres. The C marks a commercial tyre built to carry a van's load, and a passenger tyre of the same size is not a suitable substitute. Read the size and the load index on the sidewall of the tyres already fitted, and order replacements with at least the same load index. After fitting, set the pressures from the placard on the van rather than from memory.
What suspension does the T3 have?
MacPherson struts at the front and leaf springs at the rear, the usual pairing for a small van that has to carry weight. The rear track is also wider than the front, at 1,533 mm against 1,490 mm, so front and rear parts do not cross. Leaf springs can settle over time on a van that spends its life loaded, which shows as a low or uneven rear. Order springs and bushes by side and by OE number, and replace springs in pairs to keep the van level.
Does the T3 have disc brakes at the back as well?
Yes. The T3 has disc brakes on both axles, backed by ABS, brake force distribution, brake assist and stability control. Regenerative braking takes much of the work off the friction brakes, so pads can last well, but discs on a van that stands for long spells can corrode. Front and rear discs, pads and calipers are different parts. Order each by axle and side, and match the OE number on the part you are removing.
Which door parts wear on the T3?
It depends on the body style, since door layouts can differ between the box van, the postal van and the small passenger version. Where a van has sliding side doors, they open and close many times a day on delivery work, so the rollers, runners, handles and locks take most of the wear. Check which doors your van has, then order door parts by side and by the OE number on the old part.
Which charging parts wear on the T3?
The charge socket, its cover and the charging cable are the parts that see daily handling, and a damaged pin or a cracked cover is a common reason for a socket to need replacing. Charging hardware may also differ with the battery fitted, so do not assume one van's parts suit another. Match the socket, onboard charger or cable to the OE number on the fitted part before ordering.
Has the T3 had a facelift or a new model?
No facelift has been reported. The T3 was first shown at the 2015 Shanghai Auto Show and has kept the same 2,725 mm wheelbase body throughout. What has changed between vans is the specification, above all the battery, which moved between nickel-cobalt-manganese and lithium iron phosphate chemistry. Where a listing is split by date, read the build date on the identification plate, and for battery and charging parts use the OE number on the old unit.
