I have an 09 SRT, with around 1500 miles. When I pulled into the garage today, suddenly it sounded like a fan noise or vibration sound.Then the fans shutdown. I let it idle & then the fan went back on & sounded norm. I went back out for another ride, came back & all seems ok. Should I pull the fan assembly & check it? anything to worry about? If I pull it out can everything be done from the top? Don't want to go to the dealership, I rather do it myself, if you know what I mean...Thanks in advance, hope you can help...
