So I am in the process of rebuilding my 97 1FZ-FE - I bought it as a project. Bad HG and 300k Miles. No service history. My engine is all freshly rebuilt. All new hoses, etc going back on. My radiator did not appear to have any issues (single core aluminum OEM.) A local shop wants $80 to hot tank it, clean it out and pressure test it. New brass 3 core can be had for around $350 - I have already sank quite a bit on this rebuild and just want to get it on the road. For a difference of $270 - is it really worth the 3 core brass? Truck is being built solely for adventures and overlanding treks...some occasional daily driving. Thanks!!!!!
