Replacing the belt tensioner may not be a difficult task for a professional mechanic, but it was quite a difficult task for an amateur like me. This time, I was replacing the tensioner for the first time, so I prepared by watching various videos and online articles, but there were many details that were not covered.
When I made this video, I tried to explain it in detail from an amateur's perspective so that anyone working on it would have no trouble.
I think this video is probably the most detailed explanation in the world.
[Work procedure]
① Move the radiator fan shroud to the rear. (Pull out the left and right metal clips)
②Remove the radiator fan. (Remove the single bolt in the center of the fan)
③Remove the radiator fan shroud.
④ Record the route of the belt.
⑤ Loosen the power steering pump pulley bolt. (3 bolts)
⑥ Loosen the belt tensioner. (Loosen the adjustment bolt (1) in the center of the tensioner body. It's quite hard! Then loosen the adjustment rod next to the power steering reserve tank counterclockwise.)
⑦Remove the belt. (Even if you loosen the tensioner, it won't come off easily! The only way to remove it is to pull the belt and shift it!)
⑧Check whether there are any problems with the pulley bearings of each auxiliary machine. (generator, water pump, cooler compressor, power steering pump)
⑨Remove the power steering pump pulley. (3 bolts)
⑩Remove the tensioner.
Remove the damper (one bolt) and tensioner stay (three bolts).
*The bolt on the right side of the tensioner stay needs to be removed after fixing the nut at the back. It is necessary to manually insert the socket into a very narrow space! Not possible when the engine is hot! This is the most difficult part!
Remove the tensioner from the engine.
*It is stuck to the adjustment parts on the back side of the tensioner, so it cannot be removed easily. Slide the tensioner toward you, insert a flathead screwdriver through the gap, and pry the adjustment part to remove it from the tensioner. The working posture here is also quite difficult and is bad for your back! I think people with bad backs should not do it themselves.
⑪ Prepare a new tensioner. (Assemble the damper to the tensioner. At this time, it is necessary to remove and attach the pulley attached to the tensioner.)
⑫Replace the adjustment parts.
⑬Assemble the new tensioner and damper.
Don't forget to insert the adjustment indicator part between the main body and the stay!
*It is difficult to match the female angle of the adjustment part to the male angle on the back of the tensioner! This is also difficult! Bad for your back!
⑭Install the power steering pump pulley.
⑮Wear the belt.
⑯Tighten the adjustment rod (clockwise) and tension the belt. After tensioning, tighten the adjustment fixing bolt in the center of the tensioner body.
⑰Assemble the radiator fan shroud and fan.
⑱Check the operation. If the belt is loose, loosen the adjustment bolt in the center of the tensioner body and readjust it.
*In this case, you will need to reinstall and remove the radiator fan shroud and fan.
