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".
