Why Replacing Your Windscreen Wipers Matters
Replacing your windscreen wiper blades is a simple maintenance task that ensures clear vision in adverse weather. Over time, rubber degrades from UV exposure, dirt, and friction, leading to streaking, chattering, and reduced effectiveness. Driving with worn blades compromises safety, especially during heavy rain or snow. You might be wondering how to put on windshield wiper blades yourself rather than paying for a mechanic to do it. It's a task many drivers can handle at home with minimal fuss.
- Reduced visibility in rain or snow
- Streaking or chattering noises
- Damaged rubber edges
- Increased driver fatigue
When you notice your wipers are no longer clearing the screen efficiently, it's time for a change. This could be anywhere from every six months to a year, depending on your climate and usage. Understanding what windscreen wipers do you need for your specific vehicle is the first step before you learn how to change car wiper blades.
It is imperative that your windscreen wipers are in good condition for safe driving.
Identifying Your Wiper Blade Type and Size
Before you can tackle how to put on windshield wiper blades, you need to ensure you have the correct replacements. Windscreen wipers come in various designs, and fitting the wrong type won't work. The three most common types are:
Conventional Wiper Blades
These are the most traditional, featuring a metal or plastic frame with articulated joints. They are recognisable by their exposed metal superstructure. They are often the most affordable option.
Aerodynamic or Beam Wiper Blades
These blades have a frameless, curved design that conforms closely to the windscreen's shape. They distribute pressure more evenly, reducing wind lift at higher speeds. Many modern vehicles come fitted with these as standard.
Hybrid Wiper Blades
A blend of the two, these feature an internal frame within a rubber boot. They offer the sleekness of beam blades with the robust structure of conventional ones, often providing excellent performance.
The size is critical. Wiper blades are measured in inches. You can usually find the correct size in your car's owner's manual, on the packaging of your old blades, or by using online lookup tools provided by automotive parts retailers. For example, you might need a 24-inch blade for the driver's side and a 16-inch blade for the passenger side. Some vehicles also have rear car wiper blades that require a specific size and fitting.
Ensure you match both the blade type and the exact length for optimal performance and to avoid damage.
Check the manufacturer's specifications for your vehicle's make, model, and year to be absolutely certain about the correct wiper blade size and type before purchasing.
The Process: How to Put On Windshield Wiper Blades
Now that you have the correct wiper blades, let's get them fitted. This process is straightforward and should take only a few minutes per blade. It’s important to handle the wiper arm carefully to prevent it from snapping back and cracking your windscreen.
Step 1: Prepare and Lift the Wiper Arm
Lift the wiper arm away from the windscreen until it is perpendicular to the glass. You might feel a slight resistance. You can rest it in this position, but it’s wise to place a towel or cloth underneath the arm to protect the windscreen, just in case it slips back.
Step 2: Release the Old Wiper Blade
Each wiper blade has a connector that attaches to the wiper arm. The most common types are:
- J-hook: This is the most prevalent type. Look for a small tab or button on the underside of the wiper blade's connector. Press this tab and slide the old blade off the hook.
- Pinch-tab: These have two small tabs on the sides of the connector. Squeeze these tabs together and pull the blade away from the arm.
- Bayonet-style: Less common, these require you to push a button on the side of the connector and twist the blade to release it.
If you're unsure, refer to the instructions that came with your new wiper blades, as they often illustrate the specific connector type.
Step 3: Attach the New Wiper Blade
Take your new wiper blade and align its connector with the end of the wiper arm. For J-hook blades, slide the hook into the J-shaped opening on the arm. For pinch-tab blades, align the connector and push until you hear or feel a click. Ensure the new blade is securely locked onto the arm before proceeding. Gently tugging it will confirm it’s fitted correctly.
Step 4: Lower the Wiper Arm and Test
Carefully lower the wiper arm back down onto the windscreen. Repeat the process for the other blade if necessary. Once both are fitted, test them by spraying some water on the windscreen and operating the wipers. They should clear the water smoothly without noise or streaking. If they chatter or skip, double-check the attachment to the arm and ensure you have the correct blade type for your vehicle. Some vehicles, like certain BMW or Mercedes models, might have specific attachment mechanisms, but the core principle of releasing the old and securing the new remains consistent.
Carefully lower the wiper arm to prevent damage to the glass.
Common Issues and Tips for Wiper Blade Care
Even after learning how to put on windshield wiper blades, proper care ensures they last longer. Ignoring maintenance can lead to premature wear, forcing you to replace them sooner. One common mistake is using the wipers to clear ice or heavy snow. This can damage the rubber edge or even the wiper mechanism. For icy conditions, it’s better to use a dedicated ice scraper or de-icer spray.
Another pitfall is not cleaning the blades themselves. Periodically, wipe the rubber edge with a damp cloth to remove grit and debris that can scratch your windscreen. You can also clean the windscreen itself thoroughly; a dirty screen can accelerate wiper wear.
When washing your vehicle, lift the wiper arms and clean the rubber edge of the blades with screen wash fluid and a soft cloth to remove accumulated grime.
If your new blades start to streak or chatter prematurely, it might not always be the blade itself. Check the wiper arm for damage or excessive looseness. Sometimes, the arm might be bent, or the spring tension might be too weak or too strong, affecting how the blade makes contact with the glass. For specialised wipers, such as 'cool wiper blades' (referring to performance or design enhancements), always follow the manufacturer's specific fitting instructions, though the general principles remain the same.
Always ensure the wiper arm is fully engaged with the new blade.
