I have a 2008 chevy silverado with a 5.3 and auto transmission. I noticed it has 3 radiators up front. One normal one, one smaller and a real small one. I know the one is the main radiator but what are the other 2? Could one be something with the A/C and the other the tranny cooler? I do have a tow package. Also I noticed a electrical connection on the catch the releases the hood. What is that? Thanks

 

Yes one is the condenser(i think) and the small one is the tranny cooler.

 

One could be a power steering cooler - although this feature is often found on police package vehicles (Crown Vic, Impala 9C1, Caprice PPV, Charger Pursuit, etc.). I suppose you can get one for a pickup truck.
