The MB edition A catalog shows the part number for the cooling fan as 180 205 07 06. This fan is aluminum. My question is when did MB change to the plastic fan. Does anyone have an early car with the aluminum fan?

I have an early 230 here and I believe it has an aluminium fan. From what I've seen, euro cars often had plastic fans while USA versions had aluminium. The plastic fan will flex and flatten out a bit at higher engine speeds so this may of been an early attempt at reduced fan drag.

Aluminum? I thought it was a magnesium alloy.
I believe Joe (JA17) knows more how to set them on fire! :o ;D

My 65 230SL and my 67 250SL both have Aluminum Fans, I used to have a Euro 1975 280SE and it also had an Aluminum Fan. The difference between my 65 and the 67 is, that the 67 has a fan clutch.

66 and Blue is correct the fan is Magnesium.

Yes, magnesium they are. For safety reasons do not used bent or damaged ones. Magnesium is stronger than aluminum but more brittle. Damaged blades have been known to break loose and go through steel hoods on sedans! They will burn also. Later fans with fluid couplings are quieter and use less fuel.

I'll have to save my chunked fan for a campfire this summer! Years back we had an issue where a new cleaning guy threw all the mag shavings from the machine shop into a dumpster. It caught on fire somehow and the fire department was in for a surprise when they tossed on the water to douse a routine flare. The flames went about a hundred feet in the air and the dumpster was destroyed. The fines were significant...
