I recently put in a NAPA fan clutch and, while it does its job, its fully engaged for 3-4 miles every time I start it and the fan roar is too loud to hear anything else. I talked to NAPA and they said that's normal, all aftermarket clutches do that, and they wouldn't take it back. I suspect it may be a severe duty (i.e. police/taxi) unit so I'm going to get another one online (rockauto, autopartswarehouse) but I don't want to go thru this again. Can anyone point to a particular model or manufacturer that works well? I'd rather not pay dealer prices.
Also, I've heard the V10 fan is quieter. Does that equate to less airflow? If not, does someone know the part number?
