BYD Dolphin Wiper Blade Size and Replacement Guide

The BYD Dolphin uses a push-button wiper fitting, and aftermarket suppliers most commonly list the front blades as around 24 to 26 inches on the driver's side and 14 to 16 inches on the passenger side, plus a rear blade. Because listed sizes vary by supplier and market, and the owner's manual does not publish blade lengths, the safest approach is to measure your existing blades or use a fitment lookup before buying. Replacing them is a quick, tool-free job.

What Size Wipers Does the Dolphin Use?

This is where honesty matters, because the answer is less fixed than most sites suggest. The BYD Dolphin owner's manual documents how to replace the blades and when to check them, but it does not state the exact blade lengths.

Aftermarket suppliers do list sizes, but they do not all agree. The driver's side is variously quoted at 24 or 26 inches, and the passenger side at 14, 15, or 16 inches.

• Driver's side: Commonly around 24 to 26 inches (roughly 600 to 650 mm)
• Passenger side: Commonly around 14 to 16 inches (roughly 350 to 400 mm)
• Rear: A shorter blade, with the size depending on the listing

The variation is partly because the Dolphin uses more than one wiper configuration, and because left-hand-drive and right-hand-drive cars can differ. That is why guessing is risky.

How to Get the Right Size Every Time

Rather than trust a single number online, confirm the fit for your exact car. It takes two minutes and avoids buying the wrong blades.

• Measure the old blades: Lay a tape measure along each existing blade, driver and passenger, and note the length
• Use a fitment lookup: Enter your Dolphin's year and variant on a reputable wiper supplier's site
• Check the part numbers: Genuine BYD blades carry specific part numbers your dealer can confirm
• Mind drive side: Confirm the blades suit a right-hand-drive car if that is what you own

Because wipers are a routine wear item, they are worth factoring into running costs. Our guide to the average cost of servicing a BYD in Australia puts consumables like these in context.

When to Replace Your Wipers

The manual gives a clear checking routine, and the signs of a worn blade are easy to spot yourself.

• Check every 6 months or 10,000 km: Inspect both front and rear blades for cracks or hardening
• Streaking: Lines left across the glass mean the rubber is worn
• Smearing or missed patches: The blade is no longer following the screen properly
• Chattering or juddering: A sign of a hardened or perished edge

Worn blades are a safety issue as much as an annoyance, since they cut visibility in exactly the wet conditions where you need it most.

How to Replace the Front Blades

The owner's manual sets out a simple push-button procedure that needs no tools. The Dolphin comes in more than one configuration, but the principle is the same.

1. Lift the arms: Pull up the wiper arm on the driver's side, then the one on the passenger side, so they stand off the glass
2. Press the lock button: Press the lock button on the blade where it meets the arm
3. Slide the blade off: Hold the blade and pull it out along the direction indicated on the fitting
4. Fit the new blade: Follow the reverse procedure until the new blade clicks securely into place

Always replace both front blades together, so the wipe stays even across the screen.

How to Replace the Rear Blade

The rear wiper uses a slightly different hook-style fitting, again documented in the manual.

1. Position the blade: Move the rear wiper blade to the position shown in the manual
2. Release it: Press the lock button and push the blade in the direction of the arrow until it separates from the hook
3. Twist it out: Twist the blade to remove it fully
4. Fit the new one: Reverse the steps to install the replacement

Lifting the Arms Safely

One practical note, since the Dolphin does not have a menu-activated wiper service position documented in its manual. You lift the arms by hand, so a little care protects your windscreen.

• Lift gently: Raise each arm smoothly until it holds away from the glass
• Never let it snap back: A spring-loaded arm striking the screen can crack it, so lower it carefully
• Do not bend the blade: The manual warns against bending blades or obstructing them in operation
• Work on a cool screen: Avoid hot glass in direct sun, which is more prone to stress cracks

If your wipers park low under the bonnet lip, switch the ignition on and let them move up the screen first, then power the car off to hold them in place while you work.
