1995 Relay 1.9D Heater Matrix Removal

[1.9DRelay]

Hello everybody,

 

I am the original owner of this van , which has developed a leak in the heater matrix.

 

Can someone please help.

 

How can I get the heater unit out to change the matrix ?

 

The lower left dashboard can be removed and possible the radio/moulding/trim.

 

Now I am stuck.

 

Your comments would be much appreciated.

Welcome to the forum.

 

The following is from Citroen's procedures:

 

Clamp the 2 hoses in the engine compartment, remove their clips and then uncouple them from the heater

 

Inside the cabin, remove :

• The lower right part of the fascia (it shows the heater to the right of the pedals so this may be for a left hand drive)
• The bolts top left and bottom right on the heater matrix

Still inside the cabin:

Unclip the lever at the right side of the matrix from its shaft and then release :

• The lever ( right hand side)
• The plate (left side of the matrix)

Remove the heater radiator.

Hello Forum Police,

 

Many thanks for the Warp Speed reply to my problem, much appreciated.

 

I already have the new matrix from Euro Car Parts.

 

Will give it a try before the cold weather sets in.

 

I have had this "old girl" from new and she is at about 123,000 miles at the moment.

 

Never let me down and sails through the M.O.T.

 

Will post up when the job is done.

 

Keep your fingers crossed. :)

Hello everybody,

 

This is how I removed the heater matrix on my 1995 Citroen 1.9D Relay van .

 

[1]   Remove the lower left and right dashboard panels.

[2]   Remove the gear lever assembly and moulding.

[3]   Remove the top centre clock and hazard switch assembly.

[4]   Remove the centre heater control console.

[5]   Unclip  and remove the two Bowden cables from the heater box.

[6]   Remove the two rubber heater hoses from inside the engine bay.

[7]   Remove the bulkhead blanking plate from the heater pipes.

[8]   Remove all electrical connections from the heater .

[9]   Remove 3 heater bulkhead  mounting bolts from the inside of the van.

[10] Remove the gear  change cable protector plate from the floor of the van.

[11] Jiggle the heater to release it because it has sticky draught seals on the top of it.

[12] Move the heater towards the back of the van to clear the pipes from the bulkhead aperture..

[13] You will have to move the heater towards the steering column so as to gain access to the matrix retaining screws.

[14] Remove the screw between the two heater pipes which secures the mounting plate to the heater box.

[15] Remove the two screws which secure the matrix to the heater box.

[16] Remove and replace the matrix and re assemble in reverse order.

 

While you have got the heater control console out, change any blown bulbs.

 

I had a leaking radiator expansion tank which I replaced with a new unit from Citroen @ £36.00.

 

Replace the coolant/antifreeze.

 

Job done to my satisfaction.

 

Total time to do the job , about 5 hours.

 

Please be patient when you start to remove the heater box because you may break some of the plastic parts if you use rough force.

 

The old heater matrix core was corroded badly in one corner near to where the pipe connections enter the matrix..

This was causing the leak.

 

Not bad after 20 years use, a real champion workhorse.

 

Good luck.

Thankyou for getting back to us on how this job has been done. It seems a lot more than the Citroen procedure mentioned.
