Is the fan working? Is the fan installed correctly, with the air being sent through the radiator towards the rear. A fan that is not working or that is trying to push air forward could cause these problems

Hi My water pump went bad, So during the process of the repair I noticed that there are two types of pumps. One has a clockwise impeller and the other is a counter clockwise impeller. If the wrong rotation pump is installed, it will still cool the engine but the water will flow backwards causing the motor to overheat. And If the fan is drawing air from the opposing side of the radiator this could also cause the temp to rise but not enough to bring it to excessive temps, since your electric fans provide consistent high velocity air. If it was the fan than driving at normal speeds would cause an overheat condition due to the velocity of the outside air force stopping the fan from running. I would certainly check your pumps impeller rotation specs. The 350 small block has a tendency to run higher than normal temps too. Keeping a 350 cool can prove to be difficult at times. Your oil has a great deal to do with temps also. I would recommend using a quart of Lucas oil stabilizer in the pan to help reduce the heat from excessive friction. You mentioned you are in AZ. I am sure street temps can get a bit high, sometimes, installing a metal sheet under the radiator can help keep the road heat from the cooling system.
Good Luck friend!
and a Jeep Wave to ya!

If there's enough room, I would add another fan.
I have in the past removed the thermostat from my sbChevy and run without one when I had this problem, but that's the poor-man's cure. Also, I live in a climate that never sees freezing weather, so it didn't cause a problem. This was a '60s pre smog motor though.

One more thing you can do is to make sure that there is NO AIR IN THE COOLING SYSTEM. I know I am yelling but that seems to be the main issue with cars over heating or running hotter than usual. One more thing, the gague itself might be faulty. Just a thought thanks

210 is normal operating temp. 180 is just when the thermostat opens. Your coolant-water mix should be 60%coolant 40%water for maximum protection not 50/50.

how high does it go. do you have a functioning egr system, is it a pusher, or puller fan. if it only runs hot in traffic then your fan is probly not moving enough cfms

if your fan is working and your radiator aint full of dirt --you aint gonna like me --block is full of corosion rip motor apart and vat it.
cool off as soon as ya get moving -try pump first -never know fins may be rotted off -have seen it
