No I don’t have one I looked it’s the radiator in the back and the part to the Ac that looks like an auxiliary cooler. So says the rookie. Could be wrong. But I don’t think I have a cooler.

Lol I humbly stand corrected.

Having said that can anyone else chime in. You as well Geotrash. Is this standard or was it aftermarket. Looking at the auxiliary cooler with “Chevy “ stamped on it. I would say it’s factory.

Does it need to be flushed? New fluids etc. This is actually really good news.

Thank you Geoteash.

Thanks again

My '08 has automatic cylinder deactivation and it has been seemless and without issue since new. I wouldn't even know it's working unless I looked at the display. On my year mileage is bad enough to keep all fuel saving gizmos in tact.

I’m looking into getting a “Range”. Eddie I’m not great with cars and trucks. But have you had or heard of any using the device and hurting the engine or transmission?

Thank you.
