Alfa Romeo 159 Wiper Blade Sizes
This guide is for everyday Alfa Romeo 159 owners who want to replace their windscreen wiper blades without any fuss. It covers the two body styles of this model and tells you the blade sizes for the driver side and the passenger side, plus the rear size where one is fitted. You do not need any technical knowledge to use it. Just read the section that matches your car and you will know what to look for.
The Alfa Romeo 159 came in more than one generation, and the wiper blade sizes differ between them. That means you cannot simply assume the blades from one version will suit another. The sizes also matter because each side of the windscreen is a different length, so the driver side and passenger side take different blades. Getting the right size for each side keeps the blades clearing the glass properly.
Start by working out which generation you have, using the years and body style as your guide. Then look at the sizes listed for the driver side, the passenger side and, where shown, the rear. Match each side separately when you buy. If you are unsure, check your car's details before ordering. The rest of this guide explains how to choose, when to replace, how to care for your wipers and answers common questions.
Alfa Romeo 159 wiper sizes for each generation
Alfa Romeo 159 2006-2012 Wagon
Fitting details for this arm are on the product page.
Shop 2006-2012 Wagon wiper bladesFor the Wagon version, the driver side takes a 22 inch (550 mm) blade and the passenger side takes an 18 inch (450 mm) blade. This generation also has a rear wiper, which takes a 13 inch (325 mm) blade. When fitting, take care to seat each blade firmly on its arm and check that it moves freely across the glass. It also helps to lift the arm gently and lower it back rather than letting it snap down.
Alfa Romeo 159 2006-2012 Sedan
Fitting details for this arm are on the product page.
Shop 2006-2012 Sedan wiper bladesFor the Sedan version, the driver side uses a 22 inch (550 mm) blade and the passenger side uses an 18 inch (450 mm) blade. This generation has no rear wiper, so you only need to think about the two front blades. Before you fit new blades, wipe along the arm where the blade clips on so it seats cleanly. Then run the wipers once and check that both sides clear the glass evenly.
How to work out which Alfa Romeo 159 you have
To work out which generation you have, look at the body style of your Alfa Romeo 159 and the years it was built. The Wagon and the Sedan are listed separately, so the shape of your car is the simplest clue. If you are still unsure, check the details on your car or its paperwork. Once you know the generation, you can go straight to the sizes for that version.
When you buy, match each side on its own. The driver side and the passenger side take different lengths, so treat them as two separate purchases. Fit the driver side blade to the driver side arm and the passenger side blade to the passenger side arm. If your generation has a rear wiper, pick that size too. Buying the correct size for each position is the key to a clean, quiet wipe.
When to replace your wiper blades
Worn wiper blades show themselves in several ways. You may see streaks of water left behind after each sweep, or a smeary film that makes the glass harder to see through. Some blades squeak or judder across the windscreen. Others leave patches untouched. Any of these signs means the rubber is no longer doing its job properly.
Look closely at the blade itself. The rubber can split, crack or become hard and ragged along the edge. Sometimes a blade loses contact with the glass in places. If you notice any of this, it is time for new blades. Do not wait for a completely failed wipe, because that tends to happen when you need clear vision most.
Clear vision matters for safe driving, especially in rain. Streaks and smears can hide other cars, pedestrians or road markings. Squeaking and juddering are distracting and can make you tense at the wheel. Replacing worn blades is a small job that makes a real difference to how confidently you can see the road ahead.
Looking after your wipers
Look after your wipers and they will look after you. Clean the windscreen regularly, because dirt and film wear the rubber faster. Wipe the blade edges with a damp cloth now and then to remove grit. Strong sun and dusty conditions dry out and wear the rubber over time, so park in shade where you can and keep the glass clean.
When you wash the car, lift the arms off the glass gently so you can clean underneath the blades. Do not let an arm snap back down onto the glass. Check your washer fluid too, and top it up so you can clear the screen when you need to. A little routine care keeps the blades working quietly and clearing the glass well.

- Wipe the blade edges with a damp cloth to remove grit.
- Lift the arms gently and never let them snap back onto the glass.

Frequently asked questions
How do I know which Alfa Romeo 159 generation I have?
Look at the body style of your car and the years it was built. The Wagon and the Sedan are listed separately, so the shape of your car is the easiest clue. If you are still unsure, check your car's details before ordering blades.
Are the driver side and passenger side blades the same size?
No. On both generations the driver side takes a 22 inch (550 mm) blade and the passenger side takes an 18 inch (450 mm) blade. Match each side separately when you buy, and fit each blade to the correct arm.
Does the Alfa Romeo 159 Wagon have a rear wiper?
Yes. The Wagon generation has a rear wiper, and it takes a 13 inch (325 mm) blade. The Sedan generation has no rear wiper, so you only need the two front blades for that version.
How often should I replace my wiper blades?
There is no fixed number here. Replace them when you notice streaking, smearing, squeaking, juddering or split and cracked rubber. If your view in rain is poor, new blades are a sensible next step.
Can I fit the new blades myself?
Yes, this is a simple job for most owners. Lift the arm gently, remove the old blade and clip the new one into place. Wipe along the arm first so the blade seats cleanly, then run the wipers to check the sweep.
Why do the blades squeak or judder?
Squeaking and juddering usually mean the rubber has hardened or worn, or that the glass is dirty. Clean the windscreen and the blade edges first. If the noise continues, the blades are likely worn and ready to be replaced.
