[C320-list] Temperature gauge

[Barry Fahrer]

The Temperature sender on the Perkins is located behind the alternator,  I 
unbolted the alternator to get to it but you may be able to reach it with 
out removing the alternator screws.
Be sure to get a replacement that has metric threads.
Best regards;
