BMW F30 N20/N26 Water Pump & Thermostat DIY (328xi, 328i, 528i, Z4, X1, X3, 428i, 228i & more)

►The modern BMW engine is getting more and more electronically controlled. This includes the water pump found in the N20 and N26 (along with others) engines. Because it is not a belt driven water pump, this job is relatively simple with just a few tools and a little know-how. This job should be done if you are seeing any leaks coming from the water pump or thermostat housing but also if you are seeing fault codes 2E81, 2E82, 2E85.
Gareth Foley, our BMW Catalog Manager, is back in another video to walk you through the steps of replacing the water pump, thermostat, and faulty plastic upper radiator hose. This flange is known to fail and this job is a perfect opportunity to upgrade to an all aluminum flange to eliminate the problem.

[@carlosgarcia-uz4su]

Excellent explanation you are some kind of professor for tech school peace

[@CastroJordan]

When I replace the water pump, I also do the thermostat. For a few more dollars you can replace all the hoses which have the plastic connectors that get brittle with high mileage. If you are replacing the hoses, the lowest one drill a 1/4” hole and drain cleanly. As it drains take higher connections apart to vent and drain completely.

[@gottgaame]

Few more hundred dollars lol

[@ravewanderer]

If not using a vacuum, do I keep the bleeder screws closed during the self bleeding process? Where does that air go?? Thanks 😊

[@iTsBlue2]

could you guys do a video of this on the f30 335i n55 engine?

[@Stxxology]

Did you have to remove the sub frame to get the bottom two bolts out

[@Victordamus98]

Great video. Unfortunately, my BMW 428 was a pain in the a** due to the steering rack making it difficult to insert my E12 socket. The work around was using a 3/8 ratchet wrench. I was hoping it would be as easy as you showed hahaha.

[@cristianfrizziero4604]

I'm in the same situation with my 328i F30.... the 2 bottom bolts are pretty unaccessible due to the steering rack!!! I find a very uncomfortable orientation for my ratchet wrench to remove them, but i'm very worry to see if then I'll be able to put them again.....

[@carlton997]

I installed the top bolt first, and then I used a small 1/4 ratchet with a 1/4-3/8 adapter and a small E12. Take your time, and they go right in

[@DavidWendel]

When you pull the hose how much coolant actually comes out? A gallon, more or less?

[@Adam-jq6xl]

I've seen other people drain the coolant from the lower radiator hose as well as the water pump. Is that necessary, or is draining from the water pump all that's needed?

[@evelincuh1890]

How can I access the 2 bolts at the bottom?? I have a rwd the subframe covers the bottom of the pump

[@Oceansky521]

On the 320i do I need to drop the power steering to have better access to the bottom bolts?

[@dogchainsaw3923]

Hey FCP euro. I recently just picked up a 1995 Audi UrS6, and I want to do the timing belt change. Can you make a DIY video on it plz? Thank you.

[@Stxxology]

Ordered a new water pump off FCP but the Only thing I’m struggling with is trying to get the back two bolts out. Not sure how you got them did you take out anything else to get to the two bolts?

[@MarioDallaRiva]

Great instructional, Gareth. Thanks! Camera work was awesome. That air filter box looked like a meat smoker! Mmmm, ribs.... ?: When should the coolant hoses be replaced, realistically? Age? Mileage?? Thanks.

[@redihoxha2940]

I have check the engine light on my 328i 2013, first when I've test with obd2 shows a lin bus error, CD8E10, CD8E12 I've replaced the accumulator regulator anything has been changed. then added CD9010 and 1D2404. A mechanic told me that the pump communication module blocks the signal puts the whole network in emergency and turns on the check engine for that the water pump should replace. He disconnected the water pump and the check engine light stayed off. Should I replace the water pump?

[@aldrichchua9298]

Do you need to take of the belt?

[@cristianfrizziero4604]

Is there any possibility to check the pump functioning by applying 12V directly to the pins, without removing it? The bleed procedure is not working in my case but i'm not still sure it is failing.... any idea?

[@01wesleyduarte]

hello!! can i change the straight connector for square connector on the electric water pump? The pumps are the same as the N20 engine with different connectors. I've seen you do this with the high pump connectors.

[@JP-vs1ys]

good lord...cameraman....steady on.

[@velorider562]

Did this today on a non-xdrive and the 2 lower water pump bolts and hidden above the steering motor. The secert is a 10m splines ratcheting wrench and address from behind the subframe. The longer the wrench the better. I used a mountain 10m offset wrench. Thats to abother video for the wrench tip.

[@fcpeuro]

Great tip, thank you for commenting!

[@argieary]

Sir, can I ask, my BMW is F30 320i, yesterday I replaced the thermostart after it was finished I was bleeding but the water pump didn't drain the liquid into the reservoir tube, I have followed the steps, are there any other problems on my BMW?

Gareth, Which is easier? Doing this job on the N55 or these N26/20's? Imo the N55 looks easier even though you really need to be under the vehicle.

Hose damage on deep vacuum ?

[@biz4twobiz463]

Nope. It's actually the preferred method these days.

[@mascho22]

question please: Could the vacuum leak test detect a (coolant) head gasket leak if there was one present?

[@allisonspringer8152]

Technically it can but it would be difficult to know that the leak is actually coming from the leaky head gasget. If you had a coolant pressure tester and pressured the system you can pull the plugs and get a camera in the cylinders to see if any coolant got in the cylinders. Multiple ways to check a bad head gasget

Well I had to unbolt the rack and move it a bit out of the way to get to the bolts. It’s the only way…in case anyone runs into a similar rack

Hi I had the code P0597 come up and I just purchased the thermostat off of FCP and starting to gather everything to replace it but I noticed my lower radiator hose is collapsed, is this associated with this code or should I be worried about the radiator?

[@parthdinubhai]

I have the same code with no hose collapse

[@05kittycat1]

@@parthdinubhai I would definitely try replacing your thermostat as soon as you can and don’t drive your vehicle or start it and if you attempt doing it yourself make sure your battery is in good health because you will need it for the bleeding process

[@rayl3329]

Hello, Is the vacuum procedure absolutely necessary?

[@fcpeuro]

Hi Ray, it just helps in filling the system a bit easier, you can run the self-bleed procedure on the water pump a few times to reach the same goal without that tool!

Drivetrain warning and/or engine fan constantly running are signs of a failing water pump. They tend to fail slowly.
