Descriptive assembly instructions by the film:

1. Draining fluid from the cooling system into a clean container can be reused, but I recommend replacement with a new one.
2. Unscrew the two Torx T25 screws from the outflow of air that hold the lower part of the heater inside the vehicle (rubber tip draining water from the air conditioning) on ​​the underside of the car on the wall bulkhead to draw any lower housing heater (required lift, preferably driveway or channel, elevator the replacement of wheels, it's very dangerous option and uncomfortable!).
3. Move the seats all the way back, if necessary. You can unscrew the two screws on the back seat to hold them to push to the very end, but you do not need.
4. Take off the cover OBD2 interface, cover the gearshift rod 2x screw Torx T25 handbrake (leather), plastic cap and an ashtray 2X T25 Torx screws (after removing ashtrays, we pull together and pull out the 2 plugs (light and power the cigarette lighter).
5. Remove all of the center tunnel of plastic 5 T25 Torx screws, this from the handbrake and gear, only then can the entire tunnel move backwards and upwards, then pull out the car.
6. Unscrew the steel brackets console, without that we do not draw the lower housing heater and heater, because block access, 2x 2xTORX T30.
7. Take off steel hooks 8 pieces around the heater and pull the lower housing, sliding toward the shift knob, not sideways.
8. We put forward plastic ventilation air passage, because it blocks the ability to make a lower housing and proclaim the lower housing toward the shift knob.
9. To disconnect the heater with tubes, place an absorbent towel underneath the connection, because pour out the liquid from the piping and pity would flood the floor of the car, then windows will evaporate, thus rags and possibly. A container come in handy.
10. Pull out the pin, metal and proclaim the heater with binoculars plastic tubes, and no heater with binoculars (plastic switching element), is in our hands :)
11. replace the seals, clean the slot seals, seal glue on the heater housing, as well as on the old to the heater housing was at a standstill and not buzzed while driving.
12. Insert the new fuser (possibly. Only new O-rings, but clean the exact location on the O-rings) - note the O-rings or rubber seals, lubricate them, for example. Petroleum jelly, dishwashing liquid, soap or saliva. to prosper into place and not deformed by friction (insertion force).
13. Anything we give back the same way, it should be well pressed against the heater tubes and insert collateral, or hairpins, TU should pay particular attention to slides came through thicker parts of tubes, because if we do it wrong, it floods the car will be 100%
14. All activities performed by making back in reverse order, being careful to something without tearing, spoil.
15. READY, pour the liquid cooling system radiator and look forward to a new or repaired an old heater.

Top carry out work on the lift to have easy access to the outflow of air that needs to unscrew the 2 screws with a Torx ratchet low, whipped Torx T25 and the extension or two. You can unscrew the screws without a workshop crane, using lifting the wheels slipping under the car, but the car must be perfectly secure kobyłkami and additional protection in the form of wooden blocks, I recommend, however, driveway or garage of the canal.


Opel applied in their cars, two systems "types" of heat exchangers described BEHR and Delphi.

Both exchangers from different manufacturers are available from aparts.pl section: heating / ventilation
