Etec II crankshaft underdrive pulleys - $99.99 (2004-2008)

[AndrewButler05]

I've thought about doing this, but I'm wondering if it will affect the efficiency of my AC. It's hotter than Satan's balls here and since my AC will run you out of the car, I'd rather not hinder its efficiency.

How hard is it to swap? And is 15% really that large of an increase for our cars? I'm honestly asking here. Mine is a 6 Speed Custom Auto so I'm not sure if I'd notice a difference overall?

My RPM's are generally low (about ~780), so would a lower RPM effect idle or how quickly the car warms up in the winter?

Mine appears to be an odd duck in a lot of ways in behaviors compared to other Aveo's, and it has a Custom Ordered Transmission. That's why I'm curious about what this would actually alter in my car specifically.

I must be tired, and/or need to eat something since I was out late and missed dinner. My brain isn't really working at the moment.



Best,

I have a 2007 T250 sedan, any chance this will work?

The pulley will spin your A/C compressor a bit slower. This means it will cycle on more often. I think one of our members in Florida said he could notice a slight difference during summer, but thought the increased power was worth it.

Its really pretty simple. I was able to install mine in about a half hour. I have a DIY written here that goes through the entire process:

The crankshaft pulley has nothing to do with the rpms that the car idles at. It only changes the rpm of the accessories. So, this should remain unchanged.

As long as you have the E-tec II engine as shown below, it will work on your Aveo.

I totally glazed over this part of your message. 15% is pretty common for an underdrive pulley. Some go more, some less. When I installed it I could tell a difference for sure. Its not a huge difference, but its definitely there. Many of the other buyers thought the same thing.

I received an OBD II scan guage thing. I presume by mistake? I don't think it would work as a pulley haha

[Daox]

Woops, yeah that would be my fault. Please send that back and I'll get the pulley out to you. Sorry!

Could you please generate an airbill for me to use?

[Daox]

Absolutely. I will email it to your paypal email address so you can print it off.

Daox,
Would these work on an '10? Thanks, Tony
