Any tricks to cleaning the inside of an aluminum radiator? On the car we bought, the guy that put it together used carbon steel tubing for the coolant lines. I pulled those and flushed the engine and radiator best I could so far. I'm switching to use Stainless tubing for the coolant lines, but I want to clean out the radiator and engine best I can.

Were the tubes rusted? If they used an appropriate amount of coolant mixture, it's likely fine.

The tubes did have some rust build up on them. It wasn't terrible, but I'm sure some got circulated. I'll see if I have any pics to share.

Look into a product called Rydlyme. It is a descaler, bio degradeable, and is used for steam products in the food industry. I use it for boilers and steam generators.
RYDLYME Biodegradable Descaler

That is 5 gallons.

Or Evap-o-rust. It's magic and reusable.
