Glen beat me to it! I agree entirely. Consider the cost of an engine vs the 
cost of an oil cooler and once you have those values in your mind; roll in the 
cost of a lost weekend ? what do you want to risk? The problem with coolers is 
they often trap particles that can?t be simply flushed out with a low viscosity 
fluid. How many bits does it take to destroy a bearing? When you find out at 
elevated rpms it?s instantly a very expensive mistake.

 

To coin a clich? ; ? Choose wisely!? The cost of a cooler is cheap insurance. I 
always keep at least one spare on the shelf.

I have a specific test procedure that I use on oil coolers, prior to attempted 
cleaning.
It involves the use of a nasty-ass chipping-hammer, the pointy end...
Oil coolers are cheap, racing engines aren't.

I was in the industrial cleaning industry for a while and the only effective 
oil cooler cleaning I knew of was done by immersion in an ultrasonic tank with 
a pressured flow through the cooler. The ultrasonic action dislodged 
particulates which were extracted by the fluid flow through the cooler. This 
used aqueous cleaning solution (solvents do not work with ultrasonics) heated 
to 180*F and with a mild alkaline degreasing agent. It is cost justified in 
fleet maintenance settings, but buying a replacement oil cooler is probably 
less expensive for us racers.
