I can't speak to the price of the core because it's been a few years since had mine done but if you hand my guy a rad he can hand it back to you in about an hour with a new core in it. Just for comparison I put a new complete rad in my International 9400 5 yrs ago and the rad cost me about $750 cash and carry. I was at the MidAmerica Truck Show last weekend and I could have bought the same rad for about the same money.
