91 300 TE cruises at 80C on the meter, after replacing 192F stat with a 180F stat (alternative temp from Rock Auto). I live in the Savannah area where quite hot and slow traffic, so I like to stay a bit cooler.

Pix shows cruise temp at 57 F outdoors. Other pix shows temp at idle after 5 minutes, closing in on 100C.

Took rolled up bag recently obtained from drive thru where temp rise was noticed, and gently touched to fan. Made a noise like cardboard against bicycle spokes. Fan promptly stopped. Would have expected fan clutch to have enough torque to shred paper.

Radiator fins appear clear of trash.

So time for new clutch. This one is low on fluid.

BTW do not try work glove on hand to grab the fan blade. It might have enough torque left to make your nickname "Stubby".
