Always thought the extra protection of 50 weight was helpful in sunny south
Florida. Could the oil have caused that much extra temp? Oil was fresh.

Chris Miller suggested considering putting new cooler where aux rad is and
putting aux rad where stock cooler was and return original factory ducting.
I guess I could also try putting Mocal in front of main rad and have lines

thanks for all your suggestions. With the list's help, I'll eventually get
this sorted out.
