Radiator Cleaning ---

[Christopher Crowe]

I found a perfect-fit oil radiator for our one-off. But. The radiator was used as a transmission cooling unit. Two questions. Given the viscosity difference in engine oil and hypoid lubricant (or whatever is used in Champ cars these days), I think I'll be okay in terms of passage size, etc., but then this:

I'm not wild about a unit that was carrying microscopic and not so microscopic transmission debris through its little nooks and crannies.

So how do you really clean these things? I think the aircraft way is ultrasonic vibes and solvents under pressure. Is the best way to clean this thing to have an aircraft house do the above?

Thanks,

Chris

IMO, yes.
