BX fan cooling upgrade

Post by Mimic » Wed Sep 12, 2018 11:01 am

Hi,

I project to update the cooling system of my early SE5. my radiator has been upgraded. Next step is changed the fan by a citroen BX fan. I've read some topics about this modification but I'ven't seen any pictures on forum.
For me, there is no place behind the radiator because of steering wheel rack . the only possibility will be to fit it in front of radiator. But is it possible to change the air flow fan by inverse the polarity ?
Any pictures are welcome.

Thank you in advance for your answer

Unless there's more than one variety of BX fan, I thought they were all "pushers" which were mounted on the front of the radiator, blowing through it, the same as the standard fan? The BX fan is much more powerful though. I have one on the mulberry car, I'll have to have a dig in the archives to see if I took any pictures. Don't forget to add a relay, as the fan has a higher current draw than the standard one.

Reversing polarity will work - I have fitted BX fans to three cars and I don't remember having to reverse he polarity so the fan may have been in front of the rad in the BX

Reversing the polarity will work but the fan efficiency may be less due to the shape of the blades which are designed to work in one direction only

I was sure the BX fan was fitted behind the rad ...but I was wrong

Thanks !
So you confirm that the only possibility to fit an electric fan on SE5 is by the front in "pusher" configuration?

I have opted for the old favourite KENLOWE. got complete Scimitar kit of E-bay from a guy who bought it with all good intentions years ago, but never got around to bolting it on......

I fitted an Astra HX2 15" fan to the rear of my SE5 rad pulling the air through.
I just cut a recess out of the housing to allow it to fit around the rack,and made up a cowling to seal the top in.
Dead cheap and it is very efficient.
