AC belt how do I tighten it up? 95 integra LS
There's a tensioner just above the compressor. It's a bolt that sitcks out of the engine mount/compressor bracket and is held in place by a nut. You need to loosen the nut to turn the bolt. It adds/removes tension on a pulley that is pressed against the belt.
That belt has to be completely limp then or you're lucky that the bolt holding the pully hasn't come loose. Hit up a junk yard for the bolt or a dealership. You could also likely get one here: www.acuraautomotiveparts.org
