Alternator bracket bushing.. school me

I have a question about the alternator bracket that bolts directley on the water pump...the one on the water pump.
What was the reason for the rubber isolator on the bracket (alternator bracket at water pump).
Was it to remove stress from the water pump mounting ear ?
Or was it to just dampen any vibrations for the engine assy
In my custom setup, I have removed the isolator..but am worried that it was to asorb vibration from the water pump mount ear, to prevent breakage.
Has anyone run thier alternator with out using the lower isolator....did you have any problems ?
Please let me know what you think....sure don't want to break the mount ear.

Re: Alternator bracket bushing.. school me

I believe there should be bushings where the adjuster bracket bolts to the alternator too
- at least the early cars had it

I think the later ones had the bushing at the bottom of the water pump where the adjuster attached to the pump

I'd bet it was to try to spare the alternator some of the vibration inherant to 4 cylinder motors

I never thought about it being to keep the vibrations away from the alternator (not to shake up electronic if possible). Duh.
I do have the isolators on the upper long pivot bolt. But none on the lower mount. (custom setup) mounted solidly to water pump mount ear. Think over winter see if I can fit something better in there with the isolator. I'm sure they had good reasons to use it.

Re: Alternator bracket bushing.. school me

The isolator is used for vibration just as the factory used soft engine mounts to absorb engine vibration.
The 2.2L engine(not T-4)is a rough idling engine which does not matter if you can keep the vibration out of the passenger compartment.
