How many cold cranking amps should my V6 4.2 have. my battery has 550 but im not sure if that is enough

Good old Bill

Don't have the number in front of me, suggest calling the dealership, checking owners manual or perhaps the auto parts will have documented material as to requirements. Just don't rely on the counter guys. Am curious, are you haveing issues with starting yours? I purchased a replacement OEM from NAPA, but my winters are not like in Kansas.

it doesnt start real well when it has been cold. i dont have an owners manual. but i have an interstate battery that is bad that i was going to take back and get a new one from another truck. its 650 cca but didnt know if the one i have is the right size cuz i have a truck with a 5.4 and it needs a battery soon. i was planning on putting the interstate battery in the 5.4

I put a 1000 CCA battery in my truck. Starts everytime, no matter how cold it gets here in Michigan and it helps my lights not to blink when I blast my stereo.
