Great video Igor thanks mate. The heater core USUALLY blocks up because the silica bag in the header tank rips and the crystals end up in the matrix currently foxing this problem now.

Thanks for uploading I'm going to change one in my wife's 2015 Skoda over the weekend excellent clear and informative

Thanks a million for this video. It worked a treat for my car and I'm nice and toasty when I'm driving. Ran into the exact same problem as you with a broken fin after falling down behind the core and those clips are painful! Appreciate the video, I've no mechanical experience and was able to change out the core because of your video. Thanks again.

Yo man did you drain coolant or manage to clamp the pipes before the bulkhead? Gonna do this tomorrow but can't be asked to drain coolant! If so what did you use to clamp the pipes?

Have this problem right now. And I had a feeling I could sneak it out one side. Brilliant

What a legend. Thank you very much. Garages are extorting a lot of people telling them they have to take the dash out for this specific car. Just done mine following your video and after 2 years, my skoda finally has heat👊

Thank you so much brother. This video really helped me solve my problem. Was loosing Copland. Found that it was leaking from heater box.

Good walk through on matrix exchange. Very easy in this type of car. Of course the most serious problem radweld causes if its the old red stuff is that when it blocks the tiny channels in the heater matrix, the next time a DPF regen starts, the system cannot put that charge water through the matrix properly and many people believe this is what is behind the mysterious coolant losses many owners of VAG cars speak of. Have you heard anything like this?

My Octavia 3 1.6TDI developed the same problem 7 years ago but i never bothered to change it until last week when fluid leaked into the foot wells. Without inspecting the core i ordered a replacement and was sent the very same one you have in this video. Turns out the one in the car is smaller and has 2 pipes protruding from it. A lengthy search revealed it was the same as that used on an Audi TT. Eventually got the part minus "O" rings which i sourced locally. Removal & fitting slightly more involved that this but got it done and there is now heating once more.

Great video mate. Very informative.

Great video I changed mine in 3 hours but i brought new clips and seals in a kit for less than £15 from Skoda. Also when fitting the pipes back on DONT fit the plastic cover for the matrix in place till the clips are on you need to have movement for the pipes to seal correctly to get the clips on then fit the plastic cover over the matrix.

Great to show the 'working out" with the leak. Very helpful video.

Yes, Igor thanks for your video and mistakes e.g., lower pipe clamp on the core (aka matrix); although I am working on the other side of the pond and the car, the pipe clamps on my application are the same as the ones you deal with herein---you helped me so thank you very much!

Great video, just did mine yesterday (LHD Mk7 Golf GTI, slightly easier as can get away with removing lower trim piece only). Among the many other useful things in your vid it was was very useful to let me know to think about coolant draining before I popped those hoses off! What I did was use a bit of large bubble wrap I had lying around - was able to nicely wedge in behind the hoses and extend it to footwell just in case, than I also fashioned a very crude little funnel out of carboard to channel most of the coolant (I think there's round about half a liter in that matrix). Not a bad DIY job but skinned my knuckles and bruised my ribs contorting myself in the footwell to get at everything! Found myself cursing VW about those blower vents - if they were only half an inch shorter the matrix would slide right out...as it was I was able to bend them backward slightly (rather than remove more dash pieces to get to remove the vents) and get the matrix out - but very fiddly. I seriously considered taking a dremel to them and taking that last half-inch off for future ease of access!

I did drain the coolant from the lower radiator hose to minimise the amount draining out of the heater core. Also as it turns out, replacing it only partially fixed my problem - the main issue was the so called N82 coolant valve a bit further on the line mounted on the side of the engine - a right pain in the backside fiddly job, but that was the main problem as it was seized shut - having done that, the heater is now nuclear powered!

@@walruspolish Hey Danny, yeah it's pretty much the exact same way. It just depends if your car is left hand drive or right hand drive. If it's right hand drive you can use this video as a reference. Mine is left hand drive, so I needed to access the heater core from beneath the steering wheel. This meant I needed to remove the long panel between the driver seat and the middle console (1 screw in the front and a few clips along the top) and I needed to remove the knee airbag to get it out (which is rather simple, you just disconnect the battery, wait 15-30 min and remove it; but to do that I needed to cut 2 holes in a plastic cover which covers the screws; cutting the holes was described in the official workshop manual from Seat). Other than that, make sure you just use the recommended G13 coolant mixed with distilled water. The modern heater cores of the Leon 5F / Golf 7 generation are extremely sensitive and get some kind of protection from the G13 coolant. Using anything else or even tap water can lead to another blown heater core. I really hope it's just your heater core. I have the same engine in my Leon and my head gasket blew after just 97000 km - the blown heater core was just collateral damage since some stuff from the head gasket failure must have gotten stuck in the heater core.

Blowers all work well but no hot air at all. Also noticed car is using up a lot of oil. I have been told that unlike the old cars the oil and coolant don’t mix on these cars.

Try closing the passenger side vents and see if it comes through warmer on the drivers side. The symptoms you have suggest you have a partially blocked matrix. This is because the pipes enter the matrix on the passenger side, and the drivers side is at the top of the matrix. The top of the matrix blocks and only allows the hot water to pass through the first 50% of the matrix (which is the passenger end). This blockage is commonly caused by the silica bag in the coolant bottle splitting and allowing silica balls to enter the matrix. If you have calibrated the vents and the motors are running from cold stop to hot stop then it's 99% chance going to be your matrix again.

I don't think it says in the video so apologies if it does but did you flush the whole coolant system? If that amount of dirt was collected just from the heater matrix, it's likely the whole system is full of it too right? Won't the matrix get clogged up again fast if it's not flushed?

so if i have a flow in the thiner pipe i have to change heater matrix and if is not flow in the pipe then the heater metrix is okay ?

KokySS PB testing the thinner pipe for coolant flow will show if you have a good water pump able to pump coolant through the whole system including the heater matrix, if it proves to be good you most likely to have restriction in the heater matrix needed to be replaced 👍👍👍

Cars Exposed i dont think radiator is leaking because i have coolent leak but my heaters not working properly

Yep i put leak stop in mine & sure enough the heater support pump started playing up & gave me a locked fault . So an expensive mistake on my part .

I have put like 6 red Walt hahaha now no hot air at the end I changed the pipe with £20 and £20 labour . Took it to a garage and they wanted £600 to change pipe so I didn’t bother . I will do a coolant flush and clean the radiator or flush heater core if it doesn’t solve the car is ready to go to a bin .

@@nikolaeric876i have try to fix it but it ddnt do it completely. But yes it depends on what causing it. Could be heater matrix. With me silicone bag which is inside coolent bottle burst and it blocked all my system. You hope it dnt happen to you. I have drain few times change secondary coolent pump change heater matrix 3 times. Still ddnt fix probolem bcoz of the silicone bag burst in system. But ut dd start working but just on slow fan 1 and 2. Hope i answer ur question. What’s happening with yours?

I have one question, does the liquid constantly circulate through the radiator, I have a problem when the heating is turned off, the temperature is at zero, i.e. I don't want the heating to feel as if it is still heating, I touch the radiator pipes with my hand, they are hot.

Coolant constantly circulates through the heater core, what stops heating through the vent is the blend door .

These cars have a tea bag thing in the expansion tank. If the expansion tank in yours has 'milt sillicat' or something on it, my advice is to carefully remove the teabag. They can burst and release the grit like contents. Game over for heater matrix.

Would this be a similar setup for a 2014 skoda superb?

Make sure you flush the contaminated coolant from the engine and radiator after fitting the new matrix otherwise you will just clog up the new matrix giving yourself the same problem

I would probably plug the scan tool and look into the live data to see what the car computer sees, if the temperature from the ecu is incorrect I would check the thermistor by the vents otherwise check water pump flow, air locks sometimes raising the from of the car helps getting rid of air locks, if is a DSG there is another thermostat on the top of the gearbox 👍👍👍
