Understanding the Valeo Clutch Catalogue System
The IPHC Valeo Clutch Catalogue is the technical reference document that maps every clutch component Valeo produces to specific vehicle applications. It covers pressure plates, clutch discs, release bearings, hydraulic systems, dual-mass flywheels, and the accessories that tie them together. If you work on vehicles professionally or buy parts regularly, this catalogue is your starting point before you touch anything with a socket set. Valeo organizes it in two main formats. There's the traditional printed IPHC book with application indexes sorted by make, model, and engine code. Then there's the digital version accessible through Valeo's own parts portals and third-party distributor sites. Most people in the trade use the digital version now because the printed books get out of date fast. Valeo introduces new part numbers every year and retires old ones without much notice.

Here's how to actually use it without wasting three hours on a mistake that costs you a return trip to the parts counter. First, get the right vehicle data before you open the catalogue. You need the exact model year, engine displacement, engine code if it's stamped on the block, transmission type, and any factory option codes. The transmission detail matters more than most people realize. A 1999 Ford Transit with the 2.5 TDDi and a Getrag 5-speed will use a completely different clutch assembly than the same van with a ZF 5-speed, even though the engine looks identical on paper. Valeo's catalogue catches that difference. Most people don't, and they order the wrong pressure plate. Enter your data into the digital catalogue search. Valeo's official portal is valeoclutch.com and their broader parts site is valeoparts.com. Many independent distributors like RockAuto, ECS Tuning, and regional suppliers also pull Valeo data through APIs, so you'll see Valeo part numbers on their listings even if the catalogue isn't branded there. Cross-reference the part number you find against the application table. Don't assume the first result is correct. The search algorithm sometimes returns the closest match, not the exact match.
Once you have a part number, verify it on the components diagram. The IPHC catalogue doesn't just give you a number. It shows you what's included in the kit, what's sold separately, and what alternative components exist for the same application. This is where most mistakes happen. You'll see a clutch kit listed as "KD..." which is Valeo's numbering prefix for complete kits. A "KD" part might include the disc, pressure plate, release bearing, and alignment tool. It might not include the release bearing in certain markets. You have to look at the breakdown to know for sure. I ran into this exact problem last year with a 2003 Volkswagen Transporter T5 2.5 TDI. The catalogue showed a KD936WK as the complete clutch kit. Standard procedure would have been to order it and go. But the kit breakdown for that particular revision only included the pressure plate and disc. The release bearing was listed as a separate item, number 825374. I caught it because I always pull up the component diagram, not just the kit number. Had I ordered blindly, the van would have been on the lift with a missing bearing and I'd be eating a service call fee. Here's another thing the catalogue doesn't make obvious. Valeo frequently runs supersession changes. A part number that was valid in 2018 might have been replaced by a new number in 2021, and the old number might still show up in search results. The catalogue interface usually marks these as "superseded by," but it's easy to miss if you're scrolling quickly. Always check the supersession field. If a part shows as superseded, the new number might have a different inclusion list. New pressure plates from Valeo sometimes switched from a 215mm to a 228mm diameter on certain applications without changing the vehicle fitment listing. That would change your entire flywheel requirement.
Get the Full Details
When you find the correct parts, write down every number before you order. Not just the kit number. The disc part number. The pressure plate number. The release bearing. The alignment tool if one is required. The pilot bearing if it's separate. Valeo's kit configurations vary by region, so the same vehicle might have different part numbers in Germany versus the UK versus the US. Make sure your supplier is pulling from the correct regional catalogue version.
Common Pitfalls and What the Catalogue Won't Tell You
The biggest issue people have with the Valeo IPHC catalogue is assuming it covers everything. It doesn't. The catalogue is comprehensive for Valeo's own manufactured components. It is not comprehensive for vehicles that use clutch systems from other manufacturers that Valeo doesn't produce. Some applications have dual-supply clutch systems where Valeo supplies the disc but the pressure plate is sourced from another company. The catalogue will show you the Valeo parts, but you'll need to verify the non-Valeo components separately. Another problem is the catalogue's treatment of heavy-duty and commercial vehicles. Valeo makes clutch systems for trucks, buses, and industrial applications that use fundamentally different engineering than passenger car clutches. The IPHC catalogue covers these, but the application index is less detailed for commercial vehicles. You'll often need to cross-reference by chassis number or engine serial range rather than just model name. A Mercedes Sprinter from 2006 and a Sprinter from 2012 with the same engine code can have different clutch assemblies if the transmission was updated during the production run. The catalogue also doesn't account for aftermarket modifications. If someone has already swapped the transmission, changed the gear ratio, or installed a performance clutch setup, the factory catalogue data won't help you. It shows what Valeo shipped from the factory, not what's currently on the vehicle. I've had customers bring in cars where the previous mechanic had already ordered parts based on catalogue data, only to find the wrong components because the vehicle had a non-standard transmission swap. Always physically inspect what's on the vehicle when possible, especially on modified or high-mileage cars.
There's also the issue of overlapping part numbers between Valeo and other brands. Valeo manufactures clutch systems for many OEMs under contract. A BMW clutch kit might carry a BMW part number but be a Valeo-built component inside. The IPHC catalogue lists it under Valeo's numbering system. If you're searching by the OEM number, you might not find it in the Valeo catalogue at all without knowing the Valeo equivalent. Keep a cross-reference sheet of common OEM-to-Valeo mappings. It saves a lot of time.
Where to Access the Catalogue
The primary source is Valeo's official channels. Valeo Aftermarket's website has a parts finder that pulls from the current IPHC data. You'll need to register for a free account to access the full application database. Without registration, you get limited search results and no component breakdowns. If you work on vehicles professionally, registering is worth the five minutes it takes. Independent distributors also provide catalogue access. Major players like element.com, eurorim.com, and regional automotive parts wholesalers integrate Valeo's IPHC data into their own platforms. The advantage here is that you can see pricing and availability alongside the catalogue data. The disadvantage is that their interface might not show the same level of detail as Valeo's official portal. Sometimes the component breakdown diagrams are simplified or missing. Always double-check critical parts against Valeo's direct source if you're uncertain. For offline reference, Valeo still produces printed IPHC books. They're available through Valeo's commercial channels or through automotive literature distributors. The printed versions are useful as a backup when you don't have internet access or when the digital catalogue is slow to load. They're also helpful for training new technicians because the printed format forces you to look things up systematically rather than relying on search shortcuts that can miss edge cases.
The printed books are expensive and they become outdated the moment Valeo publishes a revision. If you go the print route, make sure you're getting the latest edition. Check the publication date on the copyright page. A 2019 IPHC book will have incorrect data for anything produced after that year, and Valeo changes part numbers frequently enough that the gap matters.
Practical Workflow for Clutch Replacements
Here's the process I use every time, and it's the one that keeps me from making costly mistakes. Step one is gathering vehicle information. VIN, engine code, transmission code, production date. If the vehicle is in your bay, you can often read the clutch assembly directly and confirm what's actually installed. If it's a phone order or a customer inquiry, you need to rely on the catalogue data, which means being extra careful about application verification. Step two is running the search in the Valeo IPHC catalogue. Enter all available vehicle data. Don't skip the transmission type field. Review every result that comes up for that application. Sometimes there are multiple valid clutch kit options depending on production date or regional specification.
Step three is examining the component breakdown. Open the parts diagram for each candidate kit. Note what's included and what's not. Flag any items that might need to be ordered separately. This is where you catch the release bearing issue I mentioned earlier. Step four is cross-referencing with the vehicle's actual condition. If the flywheel is worn, you'll need a replacement or a resurfacing. The catalogue will list Valeo flywheel part numbers, but it won't tell you whether yours needs replacement. That's a judgment call based on inspection. Same thing with the pilot bearing. The catalogue lists it as a separate part, but whether you actually need to replace it depends on how it feels when you check it. Step five is verifying part numbers against your supplier's system. Make sure the part numbers you're ordering match what the catalogue shows. Typos happen. A single digit change turns a valid clutch kit into something that won't fit. I've seen it happen at the parts counter more times than I care to admit.
Step six is ordering and confirming delivery details. Get the expected delivery date. If you're timing a job around part availability, factor in the possibility of delays. Valeo parts are generally widely available, but certain commercial vehicle components can take longer to source, especially if they're special-order items rather than stock parts.
Limitations and When the Catalogue Fails You
The IPHC Valeo Clutch Catalogue is a powerful tool, but it has real limitations. It only covers Valeo-manufactured components. If your vehicle uses a clutch system from a different manufacturer, this catalogue won't help you. It's not a universal reference. It's Valeo-specific. It doesn't account for post-manufacturing modifications or repairs. A vehicle that has had a previous clutch job with non-OEM parts will show incorrect applications in the catalogue. The data reflects factory specifications, not modified realities. It can be confusing for mixed-brand applications. Some vehicles have Valeo clutches paired with clutch peripherals from other suppliers. The catalogue shows the Valeo parts but leaves the non-Valeo components unlisted or references them only indirectly. You'll need supplementary sources for those parts.
For vehicles outside the catalogue's coverage area, you'll need to find alternative references. Some manufacturers publish their own parts catalogs. Independent catalog systems like Mitchell1 or ALLDATA aggregate data from multiple sources and can fill gaps. When the Valeo catalogue hits a wall, those are your next options. The catalogue also has a learning curve. The part numbering system follows Valeo's internal logic, which isn't always intuitive. KD prefixes for kits, 82-prefixes for release bearings, and various other numbering schemes that don't follow a single pattern. It takes time to get comfortable with the system. If you're new to Valeo parts, expect a few weeks of looking things up slowly before it becomes second nature.
