What is considered normal operating temp. on a 1989 Cadillac Eldorado?
At 65 mph on the freeway in 70 - 80 degree weather it'll run between 186 to 192. On hot summer days it'll run from 195 - 208.

Standing still or in heavy traffic it'll usually hit around 219 - 233.

After engine is shut off it'll go up to around 246, then back down.

Had the car shut down on me once after reaching 240 in 120 degree summer heat.

How hot can it get until damage is done to the engine, and at what temperature should I get suspicious that something is up with the cooling system?
