another overheating issue........

My 350 starts to overheat on occasion. Its fine when its idle. Just does while driving. The thermostat, fan clutch and upper radiator hose were changed less then a a year ago. Is there anything else I should be looking for?

Re: another overheating issue........

are the fins of the radiator plugged up with junk? Did you notice a lot of corrosion when you replaced the thermostat or the upper radiator hose? What kind of shape is the water pump in?

You might try having the radiator rodded out, could be a lot of funk in the tubes. Backflushing may help also. Does the coolant look rusty or muddy? I suggest using only antifreeze and DISTILLED water in the radiator.
