    28" to 34" radiator swap

    I have read the threads on doing this, and am in prcess of buying all the parts. My question is do I need to buy different radiator hoses, and will my tranny lines bolt up to the bigger radiator? I see radiators from 130-300 dollars, and don't see a difference. What brand would you recomend? I will be using the 05 tahoe fans and a nelson harness and tune for the fans. This is going on my 99 sc sb 4.8l truck. Thanks in advance.

    If you don't use the tune and just go with the harness, then you'd have to rig up a switch to activate them. Then again you can order the Nelson harness with an in the cab switch. The harness and the tune make it much easier, plus they will come on and go off with your with your a/c and go high and low speed with engine temps and/or a/c. You wouldn't have to remember to turn them on and off.
