- Just a very quick guide as ive already had to change mine, to the location and how to replace the heater matrix in a Peugeot 308, approx a 1 hour job on the drive with minimal tools.
Very well explained mate, dont forget to bleed the system up after you finished, little tip..... leave the cap off and Jack both sides of the car up helps get the air out 👍👍
what cap?
Thank you very much for your video about the 308 heater matrix, it was a big help and great time saver cheers sandy
I see you did a new video on it lol, where you didnt snap the T15 bolt off like I did, I dont have the car anymore, it got written off in December, cold icy roads when a woman pulled out of a side street in front of me, I hit the brakes, the car didnt stop....I think we all know what came next, I was going to go for a 208 to replace it, but I hate those EP6 and EP3 Engines, they are so problematic, they are a complete nightmare if you buy one where the previous owner hasnt looked after it or serviced it, so I went for a Ford Fiesta Titanium instead, 1.0 litre Ecoboost and I love it, fun car to drive.
@@seanalessi7976 cheers Sean good to hear from u, Sandy
Nice one m8, saved me a lot of time👍
Thanks for the clear explanation.
Does the 308 have a heater resister I can’t find it my heater blower won’t turn off
Awesome video, can I ask how long it takes ruffly?
how to remove this clips from pipe correctly ? and were you buy new Heater Matrix ?
Thanks for the video. How long did it take you to do the job?
No more than 30 mins including taking the bottom hose off the radiator to drain the system and refilling once everything was complete.
Thank you very much for the video, I am thinking about changing this component myself.
A single doubt, for me the problem that is happening is the opposite, that is, the air conditioning no longer cools. Approximately two months ago, I recharged the gas and it started to cool perfectly again, now after these two months, it stopped again.
After a control in a specialized workshop, through ultrasound and the filling of the system with nitrogen, I am told with 100% certainty that the gas is leaking through the heat matrix. So I ask, do you agree with that statement? Once again, thank you very much.
I wouldnt like to say, im not sure how the air conditioning works really, dont even think it runs via the heater matrix, but sounds more like a coolant leak to me, pressure test the system first and see if you can figure out where the leak is coming from, may be a simple fix.
@@seanalessi7976 It really sounds strange that the heat matrix can influence cooling. This was the test that was carried out, the system was supplemented with nitrogen (since there is no more coolant) and the mechanic says he found the leak and that it is the heat matrix. I do not know what to say. :-D
Many thanks
@@seanalessi7976 I called the mechanic to better understand the problem.
In fact, the leak is not in the heat matrix, but over it. There is another small radiator hidden above (which makes the air cold) and that is where the leak occurs. What a big problem I had.
Many thanks
Where is the heater fan located in a Peugeot 308 sw? I need to replace mine.
located in the heater box above the heater core and not easy to do.
Hi...are there any bleed screws to bleed the system after you've pulled the bottom pipe off to drain the system then refilled it?
Under the bonnet are the only bleed screws
@@seanalessi7976 Ok...i have looked for them but could'nt see them.

Hi there
Just wondered how I bleed the coolant out before replacing the matrix?!
Pull the bottom hose off the radiator, there will always be a bit left so use a towel in the passenger foot well, or once the fluid has finished coming out, take the cap of the water bottle and blow through it to get as much out as you can.
@@seanalessi7976 Nice one - thanks Sean
I have an rcz and my heater isn't producing any heat, the rcz looks very similar and is based on the 308. What were your symptoms that lead you to replace the matrix?
The same problem, no heating, but the water pipes under the bonnet going to the matrix were hot. The cause is lack of coolant changes, dirt in the system, Peugeot's matrix is very very easy to block as it has very thin pipes, I later found out mine was blocked because the previous owner of the car had used rad weld to fix a leak, changing the matrix requires a coolant change and flush, otherwise your new one could get blocked up in a couple of months too.
@@seanalessi7976 Hi, I have tried this just yesterday. Both pipes were "Red Hot". How is it possible both to be hot, and matrix cold if the fluid flows trough it? But then again when i Think of it I had a jammed radiator at my house with same problem :-)
@@srdjanbogunovic2277 The matrix has an outer jacket around it which is allowing the coolant to flow around the matrix and back out, its just not getting through the centre grill parts where the fan blows through to produce heating, if the matrix didnt have this jacket, it would build up enormous amounts of pressure and blow your rubber hoses instead as there is no way of stopping the water pump from pumping, collant is going into the matrix and straight back out again, thats why both pipes are hot, but no heating.
@@seanalessi7976 Hi Sean, thank you for the reply and the explanation! My repairman pointed out to other thing as a "no heat" problem and it considers taking off whole dashboard. :-(
I would prefer not to do that and I will try with replacing the matrix myself. Thanks a lot once again, I will report how it went trough! :-)
@@srdjanbogunovic2277 your mechanic obviously thinks the matrix is behind the dashboard, which is where they used to be, and they did used to require removing the whole dash, it used to be a hell of a job to do, I'm not a mechanic, but this job once I found out where the matrix was took me between 20 and 30 mins, just don't forget to drain your coolant first, you will still get some pour out of the matrix when you remove your pipes, just put a thick towel down on the floor before you take the pipes off, they are pretty hard to get off too, and it feels like you are going to break them with how hard you have to pull and wiggle them to get them out of the matrix, but it's an easy job.
Sean the kit I got has different clips and I can’t figure out how to put them on and where. Can u help
Just use the orinal ones, I didn't buy the kit, I just brought the matrix and used all the old parts, screws, pipe clips, cover, etc.
@@seanalessi7976 mines keeps leaking now . I don’t see how the clips do anything when they are below where the pipes connect
@@martymcgrath84 the pipes have a flange on them and where they push into the matrix, that has a flange on it too, the clips go over both flanges to hold the pipes in and lock them in, are the O rings on the pipe OK ? You have to push those pipes in until the 2 flanges meet and then put the clip over to hold them together.
@@seanalessi7976 ah I see where I’ve gone wrong now my friend. Thanks for this
I replaced mine last year been slowly leaking ever since. The clips are awful, not sure if I've done something wrong in the installation but mine leaks every time I stop driving and the system cools down. Permanent puddle in my footwell
