My BB Cuda always run hot, so I run liquid dishwasher soap in the rad for a few cycles, flushed it a few times also, then run the hose in the top and had the bottom hose off for 20 minutes or so,
rigged up a shroud and used water wetter, never goes above 180 now.

Thanks 340. I saw that dishsoap trick when working at Rentway Trucks. They used powdered soap but probably doesn't matter. Fog suggested Lucas so will sure try that, they make great products.
