All Things Chev

[the evil twin]

My Alt is on the Drivers side... where whatever is being driven off the middle belt in your 3 belt setup lives I reckon.

I also believe you have to be wary of the DOR of between the triple belt and serpy belt setups... water pump in particular

Cheers ET! Our PS pumps live up there on these jiggers.
DOR I believe it was one of your very early posts years back that kindly educated me on the serpy/V belt issue with water pumps etc...
I’ll ring AB and Rossco again now to confirm the GQ alt DOR just in case :-(

AB has just kindly confirmed again for me that his standard GQ alt’s rotation is “Clockwise” when standing in front of his beast. The plot may be thickening though as a picture also received shows his GQ alt with a cooling fan/blade between pulleys and alternator. The ‘stretched’ pimped up 170amp jobbie I’ve installed on the Chev does not :-(

@Winnie

Above pic of my alternator chop too, sorry I forgot to send you that!

[poindexter]

the external fan alternator in the pic, needs to rotate in an anti-clockwise direction

@AB mate above, can you pretty please confirm 100% for me again, sorry mate :-(

MB, most Alts don't have the "fan" on the belt pulley these days.
None of my vehicles do incl my 6.5 IE the Fords and my Trol Alts all look exactly like yours.
IE all internal fans as Poindexter mentions

You sure... IIRC those Alt setups actually draw air thru the Alt and throw it out (clockwise)... not draw ambient and force it into the Alt (counterclockwise)

Same principle as Rad Fans on Vehicles, Outboard Internal Water Pump and Inboard External Water Pump impellors on boats.

Thank you ET mate! Remembering now also that the original Mitsubishi on there that died was fanless too. What am I doing wrong here :-( ?

All alternators have fans, older style are external, later style are internal.
From my days at Bosch, I thought the air flow runs front to back. I could be wrong, it was quite some years ago.
Easy way to check is see an ,80s engine running.
