Hi. I have a 2002 4.4i, was just wondering if the power steering belt and the alternator belt are the same thing? Sometimes I get a sqeal type noise like a loose fan belt noise, it only lasts a split second as I turn the engine off and sometimes though very rare I also get it on start up! It seems to be ok thru out the day once iv driven it around for a while! Thanks in advance
