REFLECTOR: Oil cooler (FG)

[John Dibble]

Cleaning

I cleaned my standard Niagara cooler.  A lot of junk came out, but oil 
temps did not change.

2 pass

I looked at the SW 2 pass.  I requires changing the oil lines because 
one connection is on top and one on the bottom.  I wanted something that 
would be an easy retrofit.

I replaced with the Positech 20008 C.  It made a big difference.  Oil 
runs 70-75 C.  I can climb out 1000 fpm and the max temp I see is 100 
C.  CHTs are 10 C lower also.
