Used to watch your content regularly but I've been working away from home for a while. From one mechanic to another, great to see mechanics who don't mind a bit of hard graft and who is interested in how things work, rather than just throwing the old parts in the bin. Such insight can be invaluable when fault finding. I've seen a few pumps that don't have the shroud, never used one but I'm tempted to start using them. I've had two pumps now that I changed with timing belts that have had the same issue in under 18 months and seen it on several cars with the original pump.
Peter that was indeed interesting but also I can’t help feeling tha just because they can doesn’t mean they should. Seems like loads of trouble with these. Your you tube brother Dave Sterl did a cartoon on them too.
They are seriously over designed, it is quite mind boggling what they can do in a very tight space. But as you say it is a bit of an overkill, especially when they fail so regularly 🤔 Thanks J 🙏🙏
Now I could be wrong but I was told by a VW tech that these pumps stick due to not changing the coolant at correct time or using wrong coolant mix. Needs to be G13 as stamped on side of the expansion bottle and the silica in the antifreeze has something to do with causing the sticking collar.
I have heard the same. This is a 2018 car, which makes it 4 years old 🤔🤔 I don’t know when they advise to replace the coolant?? And I thought the silicate bag was to extend the coolant life expectancy 🤷🏼♂️ God only knows, I just wanted to figure out how it worked 😂😂 Cheers Chris 🙏
Very interesting Peter I’ve fitted quite a few of those pumps and I’ve never understood how they worked I had this theory in my head and don’t laugh that it was somehow hydraulically operated by the solenoid crazy I know 😂😂. Anyway like you say what a fantastic piece of engineering that pump is thanks for sharing and don’t tell anyone about my theory 😂
Don’t tell anyone?? You are exactly right. Just it is using the water & coolant mix to create the hydraulic force needed. It is a fantastic piece of manufacturing ( when it works 😬) Thanks Kevin 🙏🙏
My compliments for your very detailed videos. During a troubleshooting, is it possible to prove that the problem is due to this pump assembly, without removing it ? Thanks
Pull the small pipe off the header tank at the top, Rev the engine and if you have no flow the pump is more than likely after failing. And I’m glad you enjoy some of my content 😉🙏🙏
I don’t think many people, including the main dealers have taken the trouble to find out how these pumps actually work. (should work.) I had an overheating problem with my Passat. When the engine was hot but not overheating, I disconnected the solenoid plug under the engine cover and connect another which I insulated and left under the engine cover. ECU is happy everything is connected. I basically have turned the pump into a non-switchable unit. So far, it’s worked perfectly albeit it takes an additional few miles 2 to warm up. Even if you buy a new pump to get the solenoid wire, it’s still a cheap get out.
nice video peter i really liked the way you splitted that water pump its good to see the working of these things but i wounder why the make a water pump so complicated i dont know may be the engineers just keeping up with the times
Emission standards being so tight nowadays, the faster they get up to normal operating temperatures the better for the environment. They also say tyre pressure monitors are fitted nowadays not to let you know that you have a puncture but to reduce drag & improve emissions output 😬 All very interesting stuff 😂😂😂🍻🍻
Skoda replaced the exact same pump under warranty at just a year old, the pump they fitted doesn't shroud or electric connection, slower warm up but reliable.
Yes, it should be getting any hotter than 90 degrees. The water pump is a mechanical component and the only faults you are possibly overheating faults if the car got very hot 😉👍👍👍
Peter I know the 2.2 Mazda diesels are problematic but is there anything in particular to look out for when buying one. The 2014/15 3s are cheap as chips. 9k for something that looks good and has 130k kilometres. Drove a lot of them as company cars and they're a great set of wheels. I assume any left on the road at this stage are sorted?? Thanks🥰love the show.
Go with your gut, what I am showing are the only faults. I would definitely remove the intake straight away just for peace of mind. But I do believe they are good car with the correct maintenance 😉
@@kennedysgarage3281 your just a mechanic lol . Loved that pamflet on the ea288 . Scary stuff around the engine . Im only at 20k on 17 plate so wont see this stuff for a while , fingers crossed .
Hi there, If there is an issue with overheating does it come with some fault codes? I have got customer's superb and it overheats sometimes but there are not fault codes at all
Sometimes you can get an overheating fault code but not all the time. It is just a mechanical component and the engine ECU cannot monitor the pump itself. In my experience it is most likely the pump started to fail or sticking 😉👍👍
water pumps where great in old day you had stainless impeller good bearing and steel pulley never gave trouble. tipical vw trying to reinvent the wheel and making a balls of it 😪
They are very troublesome as it is & being undiagnosed can lead to head gasket failure. This is where the problems begin over a few hundred euros repair 😬😬😬🙏
I'm starting to think it's a fault on these engines. I've a Passat with 2 litre ea288 engine and I think the blasted pump is gone again as it's ever so slightly losing coolant. This is the second time in a year. I drive the car gently but came across your video, thought it was interesting
I have a skoda octavia vrs.. booked in for cambelt and water pump next month but the last 2 weeks it's over heated 3 times ... was going to ask the garage to stick a new thermostat in at the same time.. but now thinking maybe my car hasn't a thermostat

@@chrisc5739 hi Chris, they do seem to fail quite fast. We had one last week and as you have seen it was changed in 2022 only 80,000kms ago 🤷🏼♂️🤷🏼♂️
Brilliant video, amazing to see how much thought had gone into designing it.
Yes, I was very surprised with the details in them . Cheers Jeff 🙏

Great to see your excitement ,who says you can't teach an old dog new tricks
I just thought it was so cool once my head caught up with how this type of pump worked 😬😂😂😂
It really is awesome Peter. Great to see the cross section.
A water pump is just a water pump anymore Michael 🤷🏼♂️🤷🏼♂️
Very good information thank you sir
Isn’t it quite interesting of a design. I needed to know exactly how it worked 😊

the silicone bags burst and block the heater matrix Also there’s sand that’s been left in the engine block by factory and there’s a recall on them
Not the first time I've come on this problem.Peter
I fit the Dayco kit with dummy pump all day doing away with that disaster
It is a far better job. Over engineered to fail 🤷🏼♂️🤷🏼♂️🤷🏼♂️

Hi, have you got a link to the new water pump you ordered plzzzzzzzzzz
Skoda replaced the exact same pump under warranty at just a year old, the pump they fitted doesn't shroud or electric connection, slower warm up but reliable.
The waterpump without the shroud seems to the most widely used one at this point. It simply eliminates a bad design flaw 😉😉
@@kennedysgarage3281where could I get the water without the shroud from please let me know??????
Superb here too. What's a temperature that would be considered too hot? I'm getting no engine codes but temps are around 104-110°C. Is that a concern?
Yes, it should be getting any hotter than 90 degrees. The water pump is a mechanical component and the only faults you are possibly overheating faults if the car got very hot 😉👍👍👍

Pretty cool. Although simplicity is more reliable and cost effective and better for the environment 🍺🍺
I definitely agree Chris. It is fantastic engineering but a bit of an overkill in my eyes 🤷🏼♂️👍👍👍
Thank you ❤
Very common failure item 😉🙏🙏🙏
gates timing kit has updated water pump where always open and no difference to warm up time .
It is a lot of designing & manufacturing for what you would think is very little emissions difference. But what do I know 🤷🏼♂️😂😂😂

Back when parts were strong built & actually lasted 😬😬
I can see these pumps being nothing but trouble in the future especially with neglected coolant changes.

@@BobBob-sm3sn there is a thermostat in it too. But I would get it done asap, as the overheating could cause a head gasket to fail 😬😬😬
get ready to change it again in another 80k miles when it breaks
I actually thought I had gotten the one without the impeller cover but wasn’t prepared to wait, so just carried on 🤷🏼♂️😂😂😂
