Did you know that it looks like the Omega has a clever ECU cooling fan? 

My arch liner on the front wheelarch is missing and today I decided to check what was and wasn't likely to foul the wheel, and remove the Secondary Air pump. 

Once I'd done the pump (and found somewhere to relocate the horns too as I was removing the pump completely, I noticed a plastic tube leading from the engine bay to behind the side repeater.  I pulled it out and 15 years of muck and crud came tumbling out, complete with a big motor thing!  I can only assume it's a fan/air pump to pump cool air into or suck warm air out of the ECU location where all the wiring and fuses is.

Well, I've removed the bugger, it's clear that it's not been working for years as it was full of dirt and the motor assembly has long siezed.

I'm now plotting how or if to replace it - I'm thinking I might design something myself as now I have the tube  out I can have more of a think.

So after owning a few miggys, you still learn something each time you work on it.

Tomorrow, removing the dreaded Power Sounder!

Cheers,
James

It's not that hard a job even ham-fisted me managed it by following the how to on here and I am not the most skillful with tools by anymeans

Wondering whether to have a bucket of water handy to dump it in once removed and it starts to go off...

Mind you, if I wanted to re-fit it, that'd be it goosed of course!

One puzzling thing is that ever since disconnecting the alarm horns, I have to turn the key the last bit of the way twice for the car to start.  Hmmm.

There's no need for a bucket of water if you follow the guide all will be good

thought only very early ones had the fan...
