Can anyone help or point me in the right direction on were to find the heater matrix and remove it please. someone has put rad weld in and i think it has blocked the heater box. it will blow warm on the passanger side but not the drivers side. even the passanger side is not really hot to be honest. you can see the rad weld bits in the expantion bottle. there is no over heating no pressure when opening the cap so i take it thats my problem.

Sadly the English manual is no more, site is down, there is a Russian one tho.

But the manual only shows the car having electrical heater, you can check it out below, i don't know how correct the info is.

I would get the car warm, and try to find some hoses going to the center console, to the heat exchanger, and if you're lucky enough to find it, just try to rinse it out with water, might get lucky.

This below should be schematic for the RHD vehicle.

You can see the heater matrix, having both pipes together, so they should exit the firewall somewhere in the middle of the firewall on the engine side.

After that it might be routed to one of the sides, so start you check from there.

***** has it got 3 internal radiators. I will never clean them out if so lol. What a ball ache for some £5.00 stop leak.

There are no 3 radiators, only the one at the top has the pipes going out.

The lower, bigger one is evaporater, so should be for AC.

The tiniest one at the top should be the electric one, you model might not even have it.

Anyway your only focus is the middle one with 2 pipes going towards the engine, not so hard to spot, and pipes will probably be together on the other side of the firewall.

Nice one that is great thanks. Wonder if I can get to it behind the radio unit or up the back of the glove box area. Do you happen to no how you remove both glove box's by any chance. By the way I have had the hose pipe on both pipes coming out the bulk head today on the matrix and have managed to blow some stuff out and get both side heaters on now but they not that hot to be honest on tick over when sat so I think some of the fins are blocked up and won't be fixed any better now.

Removing glove box is quite easy, just open it all the way, check the side, there is a tiny bumper, pry it off, and then you should be able to take lower it a bit more, and pull it out.

Removing the radio is also not that hard, you pop the silver trim, then undo few bolts, you need to the silver trim around the gearbox lever, just enough so you can wiggle the radio out, no need to remove it all the way. On mine there is no code, yours should be the same, so should be ok to remove it for better access.

Just FYI, removing the whole dash is around 20 minutes job, you just need to be careful with the A pillers as there are airbags in there.

Not even my car is hot on tickover, for proper heat you need to drive it.

Hi Dean just a question mate. when you do not have your heater blower switched on is your rpm slightly lower. mine stays around 6000 rpm and when switching the heater on it jumps up and stays dead on 10000 rpm. just checking if this is normal i dont think any other car i have owned has done this before.

Yes, the car auto bumps up the RPM when you turn auxiliaries like lights, A/C and similar.
