You auxillery fan should operate when your engine temp rises (usually 105degC) over normal temp or when the a/c condensor pressure rises (causing higher condensor temps) due to low air flow. It' shouldn't run as soon as the A/C is turned on.

Newer cars will turn the engine fan on low when a/c is turned on, usually 10% speed.

AusMBtech, I noticed u r in Sydney!Are you a DIY or a qualified mechanic?
Do you have your own shop?Let us know because it's hard to find honest mechanics these days especially mercedes ones.
Where are you based at?

I'm still an apprentice but I don't have long to go

. I work in a Sydney (Australia) merc dealership.

It may be hard to find honest techs, but it's harder to find a salesman or service advisor who is willing to help you beyond their "normal boundrys", that have a good product knowledge or are willing to tell you when they don't know the answer instead of making something up. I've only ever heard of a few............

Do you do any work outside the shop or does it all go through the shop?
What area are you in?
You are right! service advisor who is willing to help you beyond their "normal boundrys", that have a good product knowledge or are willing to tell you when they don't know the answer instead of making something up. It sounds like you are 1 of the few :p

I do very little work outside the shop, it really depends on what it is. Some jobs just aren't worth doing at home.

I'm in North Sydney, but I work for G Bros, Mona Vale.

Which version of the 300E do you have? The 104 engine with mechanical or electric fuel injection?

I just had a white 300E 24V with mechanical injection come through work today. I prefer the mechanical injection, I think it's a much cheaper system to maintain/less problems than the electonic 104 injection.

Im not sure which one it is.How can I tell?
How many kms should I be getting out of a full tank?(until orange light shows)

I'm pretty sure you have the mechanical system. If you have the Air filter on the intake side then it's mechanical or if you have the intake pipe running over the top of the engine to a filter on the exhaust side then it's an electrical injection.

I'm not entirely sure what your fuel milage should be, I haven't drivng that model long enough to see the consumption rate. Try asking a few other members on this board. It may also be listed in your owners manual
