Hi, I'm a dad who needs help. My son had his engine blow on his '06 Pontiac G5 coupe last night. I found an engine this morning from an '06 Cobalt. It's a 2.2 Ecotec, same as son's G5. The seller tells me to make sure it'll work... he says the power steering works off a cam, so this makes me wonder if it's the same. It's a great deal at 50k miles and only $500. Please help!
