How to Fit Wiper Blades — Step-by-Step Guide

Before You Start

Fitting wiper blades is one of the simplest car maintenance jobs. You need no tools for most modern cars — just the correct replacement blades. Before starting, identify your fitting type by checking our model-specific guides or looking at the connector where the blade meets the arm.

Push Button and Pinch Tab Fittings

These are two different connectors that are often lumped together, and both are common on cars fitted with beam blades from the factory. A push button arm has a button on the top face of the adapter: press it and the blade slides straight off. A pinch tab arm has small tabs on the sides of the adapter that you squeeze inward. Neither has a hook — the arm ends in a flat blade that the adapter clips over. If your arm ends in a J-shaped hook, use the J-hook steps below instead.

1. Lift the wiper arm away from the windscreen until it locks upright.
2. Locate the small pinch tab where the blade meets the arm.
3. Press the button (or squeeze the two side tabs) and slide the blade down, away from the arm.
4. Line the new blade’s adapter up with the flat end of the arm.
5. Push upward until you hear a definitive click.
6. Gently lower the arm back to the windscreen.

J-Hook Fitting

The traditional universal fitting. Still common on many Japanese and budget vehicles.

1. Lift the arm and turn the blade perpendicular to the arm.
2. Locate the hook opening and press the release tab.
3. Slide the blade out of the J-shaped hook.
4. Thread the new blade onto the hook until it clicks.
5. Lower carefully.

Bayonet Fitting

Common on French cars (Renault, Peugeot, Citroën, Dacia). Uses a pin-and-lock mechanism.

1. Lift the arm and find the locking tab on the blade adapter.
2. Press or lift the tab and slide the blade sideways off the arm pin.
3. Align the new blade and slide on until it locks.
4. Check it’s secure before lowering.

Top Lock & Slim Top

Found on many modern European cars for rear wipers and some fronts.

1. Lift the arm (rear wipers: flip the wiper up from the tailgate).
2. Press the release button on top of the adapter.
3. Pull the blade away from the arm.
4. Clip the new blade on — you should feel a solid click.

Exact-fit or multi-fit? Check this before you check the connector name

If you are unsure what your arm is, the simplest answer is often to buy a blade that fits several arm types rather than trying to identify yours.

Bosch Aerotwin is coded by how it attaches: A (Original) arrives with the adapter for your car’s arm already fitted; AM and AP (Universal) come with a modular adapter set, and Bosch states AP’s four adapters cover ten common wiper arm interfaces; AR (Upgrade) is made specifically for older hook-type arms.

Valeo HydroConnect takes a different route: three adapters (A, B and C) that Valeo says fit up to twelve arm types and around 96% of the European car parc. Valeo’s Silencio range, by contrast, is exact-fit.

A note on naming: Bosch and Valeo publish their own connector codes rather than the retail terms used above, so “push button” and “pinch tab” are trade shorthand rather than manufacturer categories.
