globalinfosource Posted July 5, 2007 Share Posted July 5, 2007 this is really stupid of me to ask but how do i tighten my timing belt?ive never had to lol. Ok..... Somewhere in the middle to right hand side of your plastic timing cover is a black plastic plug... Remove the plug there should be a 14mm bolt inside... Loosen the bolt slightly but not completely maybe 1 to 2 revolutions... put a 17mm socket on your crank pulley turn your crank 1 full revolution counterclockwise then tighten the 14mm bolt and you are done!!

Make sure you use a six point socket for the 14mm bolt that way you lessen the chance of stripping it... Link to comment Share on other sites More sharing options...
Kastigir Posted July 5, 2007 Share Posted July 5, 2007 Aren't timing belts auto tensioned? Link to comment Share on other sites More sharing options...
globalinfosource Posted July 5, 2007 Share Posted July 5, 2007 Aren't timing belts auto tensioned? They are auto tensioned... Over time the rubber stretches a bit.. Loosening the 14mm bolt allows the tensioner's spring to auto adjust... Turning counter clockwise aids in this process due to the fact that the tensioner is located on the right side of the belt run directly under the water pump. So by turning CCW it tightens the belt on the long span from the cam sprocket to the crank sprocket then the tensioners spring takes up the slack. Also I would inspect the entire belt after you finish up. If there are any cracks or the belt looks dry rotted i would reccomend replacing it..

cranny Posted July 5, 2007 Share Posted July 5, 2007 hes right , except you shouldnt rotate the engine a full turn to tighten the belt , just a 1/4 turn. and when you crack the tensioner , only loosen the bolt about a half turn. if you loosen it more , it actually makes the tensioner lean down , so when you tighten bolt , it pulls it back straight , and makes the belt tighter than it should be , if you follow.

eg9-civic Posted July 5, 2007 Author Share Posted July 5, 2007 the motor i got only has 100k, i think there was something wrong with my tensioner so i put a pry bar below it and held it up when the bolt was loose then i tightened it when i felt it was tight enough.

cranny Posted July 5, 2007 Share Posted July 5, 2007 you should NEVER DO THAT. if your tensioner wasnt pulling the slack , the spring prolly fell off or was missing. Link to comment Share on other sites More sharing options...
eg9-civic Posted July 6, 2007 Author Share Posted July 6, 2007 the spring is on there and pulling it up, but ill tighten the bolt on it and then it has like 1.5 in. of slack which i know that cant be good. so i went ahead and auto tensioned that crap myself.

greydey Posted July 7, 2007 Share Posted July 7, 2007 How does one know when it is time to tighten or change one's timing belt? My 2001 Civic has 148,000 kms on it and it rarely is left outside in the winter (which I hear contributes to the need to replace the belt?) Where is the timing belt anyway Link to comment Share on other sites More sharing options...
