Well.. I agree with Mighty Mouse here
But I checked the link.. and it seems you're not gettin any SES lights or any kinda error.. so I say if you it'* working.. then leave it.. save the $$ for some nice octane booster or something else. If you're concern about the fan not coming on.. just start it up one day and let it idle on your driveway for 10 minutes+ or so.. I don't know bout your year but mine you can barely hear the fan coming on ( even when I turn the A/C on and KNOW they are on by lookin under the hood to see them both turning )
