Fitment Notes
- Always verify the OE part number stamped on your existing water pump before ordering. Fitment data is provided as a guide and may not cover every sub-variant.
- This pump fits the VAG EA211 engine family. SEAT and Skoda models sharing this platform (e.g. Ibiza, Leon, Fabia, Octavia) may also be covered — confirm the OE number.
- Engine codes listed are representative; multiple sub-codes exist per model. Match the OE part number for positive confirmation.
Installation / Use / Maintenance Tips
- Drain the cooling system completely before removing the old water pump to minimise coolant loss and contamination.
- Clean all gasket mating surfaces on the engine block thoroughly before fitting the new assembly.
- Inspect the thermostat, radiator hoses and timing belt/chain while the pump is accessible; replace any worn components at the same time.
- Refill with the manufacturer-recommended coolant type (typically G13 for VAG vehicles) and bleed all air from the system before starting the engine.
- Run the engine to operating temperature and check for leaks around the pump housing, hose connections and bleed points.
Common Questions
- Will this water pump fit my vehicle?
- Check the fitment table above and confirm the OE reference number matches the one on your current water pump. If your vehicle and engine code appear in the table and the OE number matches, this pump is a direct fit.
- What do the OEM reference numbers mean?
- OEM (Original Equipment Manufacturer) reference numbers are the part numbers assigned by the vehicle manufacturer. They let you cross-reference this aftermarket part against the original to confirm compatibility.
- What is included in the box?
- This is a complete water pump assembly with housing and 28-tooth drive gear.
- Is Partquip the same as MAP Pro?
- No. Partquip is an independent aftermarket brand. MAP Pro is the house brand of Modern Auto Parts. Both are available in our store, but they are separate brands with their own product lines.
- Are there other variants of this water pump?
- This listing covers SKU WA030 (with housing, 28-tooth). Other water pump SKUs in our range may suit different VAG engines or configurations — search “water pump” in our store or contact us for assistance.

No recomiendo
Format: Paperback
Muy malo, no vine completo, además se demoró mucho más de lo que decía al momento de comprarlo. Solo aplazaban la fecha de entrega sin consultar cómo afectaba al cliente. Yo tuve que presentar el examen sin el libro, porque no llegó en la fecha que decía al comprarlo y después se cambió 3 veces la fecha, casi cumpliendo el mes.

There's nothing else out there that's this comprehensive
Format: Hardcover
Unlike my last review, this one I'm happy to write. I'm a game engine programmer, but I don't have a long history with games, and how their engines are typically structured. Every in-house AAA engine will be different of course, and obviously you won't find books (or typically any docs at all really) on the structure of these behemoths, so the best you can hope for is something that tries to give you the high level overview of what to look for - how a tools pipeline is setup, what subsystems to expect, how they interact, etc.
This book provides all of that, and so, so much more. I really can't believe how much is packed in this thing. A really nice section on OS fundamentals, extensive coverage of concurrent programming, tools, audio, physics, it's all there (in one way or another). Like most of these kinds of books, you probably don't want to try and read it front to back (although that would be awesome, who has the time for that?) Instead, I've been going to sections on an as-needed basis and picking up just the stuff I need most at that time, and it's been great.
I'm at the point in my career where I'm just not buying as many books as I used to, either because they don't deliver on their promises, they only cover the basics, or they just rehash things that have already been covered extensively in other books. This book's definitely got me excited, because it provides a ton of real-world info that's hard to get anywhere else. 100% recommend to anyone new to game engine software development.
UPDATE: 6 months later, and this book continues to amaze. After studying every line of code in the section on memory allocators, I've added this feature to my engine and it works great. Same with quaternions. I just keep finding myself reaching for this book! What a great resource, rock solid.

Don't peek at the next page.
Format: Hardcover
Basically, best practices in game engine architecture, citing a wide array of game engines used by a wide array of top game makers.
Out of a ~1150 page book:
The longest chapter is ~150 pages, on Parallelism and Concurrent Programming.
Rendering Engine is ~100 pages
Collision and Rigid Body Dynamics is ~100 pages
3D Math for Games is ~50 pages
I had hoped for treatments on quaternion camera and for entity component system, but alas, no.
What I did get was still crucial. The most illuminating guidance was in Engine Support Systems (~50 pages) which talked about best Memory Management, and in Game Loop and Real-Time Simulation which talks about ideal orders of operations in a highly efficient game loop.
The first 400 pages of this book are not exclusive to games. A new programmer that wants to do high performance programming can gain a lot from this before it gets into 'primarily' game topics.
My strategy for getting through this whale was to never peek at the next page. I did not read (Character) Animation Systems (~100 pages) or Audio (~100 pages), as I do not need them at this time.
You can certainly damage the book if you don't keep in mind its weight, or if you do that maneuver where you forcibly open it against its spine. I did that and the binding popped off the backing. It's all in one piece, and it's easier to read. It's a big tome.

The Bible, if it was good
Format: Hardcover
I’m not kidding when I say the first 350 pages of this book are quite literally an entire computer science degree. In fact, many CS majors would learn more about some of these subjects here than in their classes. I’m incredibly impressed with the thoroughness and depth of this absolute tome, and I’ll be far more impressed if the binding is able to hold on to all 1200 pages for the whole time it takes me to read it.
