I did a lot of searching for the Sachs 'Horton' fan clutch for the 98/99 E300D and the Mercedes brand fan for a 98/99.
Found them both on a website with free shipping and reasonable puchase price.
Pictures are attached
1. Fan Clutch is a Sachs 'Horton' brand but appears to have been made in Nov 15th, 2003. It shows what appears to be corroded ' rebuild ' residue on the thermal plate. I was expecting a new one made in the past year or so.
2. Mercedes fan, initially I thought it was a cheap Chinese knockoff due to the white printed label from a company called Newparts not the company name I ordered from. After looking closer I found a Mercedes logo and part #. I'm still a little concerned it might be a mirror image copy of the Mercedes part.
I'm concerned because they sent a ' probably rebuilt ' fan unit that was made 18 years ago.
The link to the web page for the clutch is:

to me it should have been a new one since it wasn't mentioned to be rebuilt.
What are your thoughts?
