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.
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.
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 🙏🙏
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 😪
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 😂😂😂🍻🍻
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 😬😬😬🙏
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 😉🙏🙏
@@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 .
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 😉
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
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
