Normal temperatures

[jwhite1149]

That temp on the head below the hose is 203-208 taken with my infrared thermometer. Below that on the center of the exhaust manifold temp is 350+ is that too hot, could it be the cause for the head temps? Have new water pumps, flushed radiator/engine with 4 gals. of vinegar (ran it for four days), drained a lot of rusty vinegar out. But no improvement in temps. Help.....any ideas??

Under what conditions are you getting 203 to 208 ?? The manifold temperature don't effect the water temp in this case. Most old Fords will idle at close to 200 after being driven at 170 to 180 on a hot day. The temp even raises higher when the engine is shut down. Raising the hood after shut down lets some of the heat out. These engines have poor fans so avoid heavy traffic and long idling on hot days. When driving the forced air from forward motion going through the radiator is what cools these engines. Again the only temp you need to check is on the heads 1/2" below the hose. G.M.
