2007 Honda civic ex 1.8 4 door with a/c. Need a part number or size, for the bolt that goes through the eyelet (Not pulley), for serpentine belt auto tensioner please! Went to Honda and was sold a $4 bolt that was way too big. Any help is appreciated. Thanks.

 

I have a 2008 Civic LX with the 1.8L engine. The dealer sold me 2 bolts, as they did not know which one was the right one. The part numbers are 96700-10055-18 and 90001-R1A-A00. The 90001-R1A-A00 bolt is slightly longer, having an unthreaded tip on the end. The 96700-10055-18 bolt is a bit shorter and is threaded all the way to the end. This may be the bolt you need (ed).
