I just went down the street to this radiator shop thats been in business for the past 15 years, as he was checking over the radiator, he kept asking me if someone installed the second fan, cause from what he tells me in the time he has been changing radiators, hes never seen 2 fans in a row (the regular fan and then inside near the radiator the mini fan), anyhow i kept telling him that this engine is completely stock, but he was skeptical...anyway i left so they could work on it in the morning, I"m a l;ittle worried they will do more damge than good...btw all 240s have 2 inlined fans right? i hadnt had the chance to check another 240

 

dont' worry about it. unless its aftermarket, every 240 has a clutch fan(the fan spun by the engine) and a little 10'' puller up against the radiator.
