Crank Pulley Size?
 

I'm not sure were to put this so i apologize if its in the wrong place.

Its a very general question not a single model specific one.

What is the Stock Crank Pulley size?

This thread says 6.25" : https://www.cobaltss.net/forums/show...ght=crank+size

This one says 6.50": https://www.cobaltss.net/forums/show...ght=crank+size

And if they are different can you please list the sizes for each one.

Thank you.

wow such a helpful community :/

Not sure what the actual size is but have you noticed that one link is for the 2.0 and the others are for the 2.2/2.4

all stock ecotecs use the same size crank pulley though

yes i noticed that i want all the sizes.

This is why I need a service manual... none of my literature has the spec in it... Sorry dude, post it up here when you find out

I have the service manuals and they dont tell you not that i could find.

Stock is 6.25".

you clewarly didnt read the OP

I don't know where on the pulley you measure ie from the inside of the grooves or the outside, but I measured my stock one and from side to side (grooves notwithstanding) the pulley was 6.5". Hope that helps.

You would probably get a quick answer if you pm'd MRZ.
