OE manufacturer part list

[Slideways]

Saleri basically only makes water pumps. They are a major WP supplier. Febi-Bilstein barely makes these for BMW and not water pump OE for anyone that I'm aware of? You'd be hard pressed to find their WP even in the marketplace. Saleri is OE for BMW, (Audi, Mercedes).
Yes I'm aware Saleri is in Italy. Still I would be very surprised if they get their impellar from Febi, if you look at the only E46 waterpump they did make it didn't have markings anyhwere near the ones Saleri has and the Febi brand one doesn't even have GERMANY on it. But I do not know, so it's possible.

E46 Febi from their own website

Saleri isn't OE for the E46 M3 based on the images in their product catalog - http://aftermarket.saleri.com/web/ca...9%20(E46)%20M3

I'm sorry my last post was in regards to Febi-Bilstein making the impellers.

I understood that and I checked the Febi website before posting my previous post.

Edit: Neither make the impeller or the OE pump for BMW.

It looks to be the case. Initially searching for "GPM waterpump" only brought up other waterpumps and their GPM = gallons per minute.

👍🏻 Thank you for this. NGPM.
I was thinking INA might make the impellers and bearings but nice to have this info finally.

Does anyone know the OE manufacturer of the expansion tank & lower/upper radiator hoses?

I believe the tank is Modine. Not sure about the hoses.

I think all hoses were continental, now owned by CRP (Rein) which is the OEM version you can get nowadays. $16 & $14 for them.

Has anyone seen the quality of the Rein hoses compared to the BMW brand? Big price difference.

I'm not worried about the hose part, that's pretty standard. It's the o-rings that seem to be an issue. You're better off reusing (lube it with silicone grease) your old stock o-ring (in each hose end) or getting upgraded aftermarket orings like from Wolfn8tr here on the forums.

I made a thread about OE timing chain. Got the Bmw chain in and it is in fact IWIS. Both the timing and oil pump chain are IWIS!
