How many fans for the diesel?
 
how many different types of engine/air con cooling fan were fitted to the diesels?

Are two speed and 3 speed interchangeable?

Two and yes (diesel control box must be retained).

Now what's the actual problem Ian?

Hi Simon, no actual problem. I posted as I was going to the scrap yard today and was going to get a spare fan which I have now done with control box and a few other bits.

I think they are the same from another thread or something I've seen as the one from the scrap yard has the silver resister as does mine.

I could have wasted my money but fingers crossed I haven't.
Just wanted to know if I found one that is not the same if it would fit and work.


This leads me to another question. I have my saloon in bits so accessing the plug for the fan is easy, I'm unsure how to test this "new" fan, can you advise?
I dont want to run the air con as there is no gas in it.

You will need to plug it into your saloon and do the demist test. There's no harm in doing this because the diesel doesn't need the engine to be running for this test. Be sure to weigh down the fan very securely though otherwise it will become a helicopter. :eek:

checking the labels on both fans it is the same. I don't know how often these fail but
i'll hold on to this

Change the silver resistor for a gold one and your spare should last quite a while, you could always open it up and check the brushes, and if they need changing do so. ;)

I think they may need changing, spinning the fan backwards does seem to give off a brush sound but forwards is ok. The one on my car is ok in both directions.

I was wondering if I should change the resistor.

Have you a link to replacement brushes please Arctic.

omg not cheap, I'm reeling seeing the price, about what I paid for the fan :)
I know a new fan is more and how important the fan is but I'm still shocked

These brushes were created specially for us Ian. I sent an old one of mine to the company and they examined the material and drew up a specification. The contact area is shaped to fit the commutator exactly and the connection is by braid, exactly like the originals. They are a custom-designed, high quality product. I repaired my fan motor with them and that was ten years ago. One or two people have chosen cheap brushes on e-bay of unknown origin. They failed very quickly.

These brushes won't be a high volume sale for Engineering Carbon Products. After deducting first class postage they cost less than 5 each (remember they're custom-made). You compared the cost to that which you've paid for your spare fan which is second-hand and will require a new gold resistor. You also don't know the condition of the commutator or the brushes and, unless you've tested it, you don't even know whether the PCB works. Your purchase carried an element of risk, as all second-hand sales do. There isn't really a comparison to be made with the ECP brushes. I'm therefore surprised that you've made a fuss about what is, after all, a small amount of money for any repair on a car.

Regards,

Simon
