my car sounds like its a semi when you are driving it down the road. you barley hit the gas and it sounds like the fan is blowin all the air straight up into the hood. I have changed all the belts in the last week and replaced the clutch for the fan but it is still doin this. when we pop the hood u can feel the air goin straight up and straight out to the driver side i need some advice on what it might be

is there any restrictions in front of the condensor or between the radiator and condensor?

have you let the car warm up completely since you replaced the fan clutch and rechecked if it did it warm?

all 240s have very loud fans, and you should be able to feel a lot of air blowing when you open the hood.

Remove the mechanical fan, and rewire the condensor fan. No more noise, and better throttle response :)
