Another thing is they do not have drain pet-cocks so you need to pull the bottom hose to drain the radiator, not a real issue. I suggest getting a electric fan so you don't need to drill mounting holes for the factory shroud. My 16" Perma-cool works great, I have a Stewart H2O pump and a 180 thermo, I can drive with out the fan on most of the time if I am crusing and it may reach 180 degrees, usually runs around 175.
