Heather box new fan

[Marc Verspecht]

Hi everybody like i already promised I am going to put the pictures of the progress I am making on the swap of my fan for the heater box . Be free to give me your thoughts en a little help on the reconnection of the electric wires would be well appreciate . So her we go

Next take the plate out the are welded in at 4 places on ether side . The upside you have to cut out .

Next the adjustment of the fan in the new space . You are going to grind away some plastic to be chure it's flat on the bottom of the fan where the air intake is .

Next I have found some foam witch can not rotten out you squeeze it in en til nothing can move anymore . Then you check the air gaps en you close them also with foam .

Would it not be better to fix it in position and then use expanding foam?

Hi Peter I have bin thinking about that but the risk of ending up with a mes was to big . It is well blocked from everywhere en can not move anymore . Did a test en I have no loose of air . I think it's going to make a difference . Tomorrow I will reassemble the rest of the box . En then the hard part putting the cables the right way . cheers Marc .

Hi Marc,

You have to make sure that the foam that you have used is not flammable, and will not be affected by the high temperature of the engine bay and the heater box. Perhaps it would be better if you also could screw the new fan assembly to the heater box.

Something else to consider, is to seal up the rear opening of the fan cage. The P6 heater box is designed to suck air from the front chamber only, that is fed from the air intake between the bonnet and the windscreen. If you leave the rear open, There is the posibility that the fan would suck also air from the engine bay, and this is something to avoid. Alternatively, you can take advantage of the rear opening of the fan cage, and use it to create a recycling facility when the main air intake flap is closed. However, this is going to be more complicated, and to be honest and don't find recycling very useful, even in moderns.

Regarding the electrical connections, you need to pull one more wire from the heater box feeding harness, to the blower switch in the centre console. I think that you have to remove the console completely in order to reach the internals of the switch. Another option would be to fit a new 4 position switch, or just use 2 of the 3 available speeds of the new blower motor, for example 2 and 3, if you check and decide that this fits your needs.

Hi Demetris, thank you for your reaction I am going to run the fan for a while to see how warm it is actually going to get . The foam chood be heat resistant . But in this case I want to be on the safe side . By closing the box I don't understand very well wat you mean . I thought the fan was sucking is air by the small round at the front plate of the fan . I am going to go for a to speed solution I think It would be possible to at a 3 speed to if I take it of en other switch . But for me the most important thing is tho have a good air flow when I have a misted window en hopefully some heat in winter . I keep you informed , en have a nice weekend . Cheers Marc .
