The a/c in my 89 300e does not cool when the outside temp is above 90 and it is at idle or stop and go traffic. Once the car gets on the highway for a stretch the air gets ice cold. I'm thinking that the V-fan clutch is bad, although, engine over heating does not seem to be a problem. At idle, I can stop the fan with my gloved hands. Can the fan clutch be removed without removing the radiator first? Is it repairable or does it need to be replaced? How can I test it? There does not seem to be much clearance between the raditor and the fan clutch especially when you factor in room for the wrench. Any thoughts?
