HI,

Had an issue losing coolant. A friend, who is a Deisel fitter, took a look and found that the heater matrix was leaking. He has temprarily bypassed it so we can drive the car, but with the weather turning colder I need to replace it.
I have a TIS CD and have looked at it, but there are 2 sets of instructions which have pretty dissimilar steps - one set saying the A/C system needs draining . The car has A/C.

Does anyone have a step by step guide to get this job done? Or any advice based on the experience of doing it?

Thanks

i think it can be done by dropping the bottom cover off the heater, its tricky, but very possible.

the aircon has a totally seperate matrix higher up in the heater

It is fairly straight forward:

1) Drain coolant into bucket - rhs lower radiator hose. If the coolant is still a nice blue/dirty blue, it can go back in. If black or smells funny (you would know), it's time to replace it.
2) Remove the side plastic panels (held on by 2x screws). You'll need both sides off.
3) Detach the plastic clips from the lower plastic section of the heater matrix box. These tend to break, so make sure you have several cable ties ready to go when you put it back together again.
4) Pull heater matrix unit about 3-4 inches into the cab to gain access to the clips.
5) Remove clips using mole grips. I have since replaced mine with jubilee clips as they only require a 6mm socket and I don't have to worry about the limited space.
6) Check if hoses are squidgy - if so, you may be able to get away with removing an inch of rubber to create a good seal when you put back. Else, for £20 you can get a new wire-reinforced aftermarket hose.
7) Make sure you have something to mop up any dropped coolant.

Reverse fitting from point 5. I'd say it takes no more than about an hour to do for the removal. Any questions, PM me. :)

i did it, i put high pressure car wash Gun in inlet pipe of heater matrix, and clean it... and now i got hot air inside.
before this, both pipes of heater matrix, outlet and inlet were warm, but there wasnt hot air inside, just a little, and matrix get cold after 1minute, because hot water didnt going easily trough matrix.
now everything is ok, so if you have this kind of problem, its better to clean matrix before buy new one. thanks to all for help ;)
