Failure symptoms: the engine has a different sound, it seems that the pump has a different sound.
    Diagnosis: first remove the air conditioning and power steering pump belt, and then remove the noise of the larger fan belt, hand-turn alternator, that is not what the feeling of scraping, this part of what should be the problem. The problem is still on the pump, carefully observe the engine room, air conditioning compressor and power steering pump are installed in the back. So do not remove the air conditioning compressor and power steering pump can not remove the timing belt.
    If you do not remove the timing belt, you can not remove the pump, generally because the replacement of the pump and disassemble the compressor power steering pump.
    First remove the air conditioning compressor and power steering pump. Then remove the timing belt cover, then remove the timing belt. A look at the pump, and the current production of the pump is different from Japan, not one, loosen six 8mm screws, you can remove the pump turbine.
    Split 6 8mm screws, originally should be able to simply be removed, who knows the six screws is very difficult to demolition.
    The mechanics know that the screws are steel and the screw holes on the pump side are aluminum. Because it is tight, drop some of the penetrant, stop for a while will continue to disassemble the screw operation. In the operation of a screw disassembled, and these do not remove the total pump to die, and now can not directly replace the pump assembly.
    Remove the two mounting screws to remove the pump assembly, first with a clamp clamp, and then use the torch heating, carefully all the screws are removed. Because the pump is aluminum, the mating surface with sandpaper after grinding and then assembled, and then installed on the engine up. Then, the timing belt, fan belt, steering pump, air conditioning compressor installed. The job is over.
