A/C Belt or Tensioner Replacement

Replacing your A/C belt or tensioner bearing.



Although the vehicle used in this case is an CRX SiR, the process is the same for a wide variety of Hondas.


As the car here is a JDM SiR, we will remove the power steering pump to gain a little more access to the A/C components. Also, as the power steering belt is the first on the pulley you will have to remove the belt first anyway so it's sensible to replace it at the same time.


Remove the support for the A/C pipe from the top of the power steering bracket and flip it back out of the way. Wind back the tensioner screw for the pump also with a 10mm socket.

Remove the upper and lower retaining bolts for the power steering pump.


Lay a shop towel on the rocker cover to protect it from scratches and lift up the power steering pump out of the way, with the hoses attached.


You can now gain easy access the A/C pulley setup. Wind back the 10mm tensioner nut and loosen the 14mm pulley nut which will allow you to remove the belt. If you are not removing the tensioner, then you need only crack the pulley nut to allow the tensioner to drop.



Refitting is the reverse of removal. Be careful not to apply too much tension to either of the belts.


Replacing the Tensioner Bearing
