This ebay unit is made in China and certainly doesn't look original to boot. All 2 row 1" tube aluminum radiators are made with what's called a "high efficiency" fin design (3/8th " fin versus OE original 1/2" fin design), otherwise wouldn't work at all, and therefore drops temperature better...

Not asking you to spend another dime and doubt that anything I say or do will change your opinions. Give me an address and I'll have it picked up and send you a refund on that invoice along with the shroud as well. No fights, no arguments, just feel your pain. D-

SlinktRR, in answer to your original question about "Optima" core I would advise against it. The Optima consists of a 1/4" fin and tube spacing designed for maximum heat transfer points in the core (twice as many when compared to the original unit) to be used on high horse power and blower...

lewtot184, for the record, the two rows of tubes on the outside of the core were simply put there as filler and were not in the original radiator to begin with. The original side bracket wrapped under the bucket header and up against the core in order to fill the gap that would be there if the...

Thanks for your comments John. We've already had a meeting and discussion on this issue this morning with the folks involved and will have another before the end of day to better address your problem. While our warranties are fairly specific to the radiator itself however, all things are...

Hi guys, this is Don from US Radiator and have been a member here for many years. It appears I owe a couple of you an apology for poor quality and customer service and wished I had known of the problems at the time. That's not who we are or how we work and I sincerely apologize. That being...

If the car runs cool at freeway speeds under a load then your radiator has adequate heat transfer for the engine under horse power. If it tends to heat up at low speeds or idle it's not your radiator and would suspect air-flow or coolant flow. Build a shroud or come up with a way to mount your...

Wow, I'm a new member on this forum and just learned something about Chry. water pumps.. Very cool.. Did small blocks also have two different impeller options?? Don A

Pressure in the cooling system (which is a sealed system) is created by increase in heat.. If your engine wants to run at 180-190 for example, a 12-14 pound cap will be sufficient to hold the resulting pressure.. Above 200 you may want to go to 16 on a copper/brass radiator. Keep in mind it's...
