I REPLACE THE RADIATOR SO IT COULDNT BE THAT, I REPLACE THE THERMASTAT SO IT COULDNT BE THAT,I REPLACED THE RADITOR CAP ( FROM KRAGENS) I BOUGHT A NEW MOTOR FOR MY COOLING FANS SO I DONT THINK ITS THAT. THE FANS DO WORK. WHEN I DRIVE 30MPH AND UNDER IT OVER HEATS DUNNO WHY I REPLACED MY FANS AND THEY ARE ON WHEN I DRIVE. WHEN I DRIVE 45 OR MORE THE CAR DOESN OVERHEAT THE TEMP GOES BACK DOWN WHEN I GO FAST. I CHECK TO SEE IF THERE IS A BIG CLOUD OF WHITE SMOKE WHEN I TURN THE CAR ON AND THERE ISNT. I CHECKED MY SPARK PLUGS AND IN SIDE WAS NORMAL. SO IF IT WAS NORMAL IT COULDNT BE THE HEAD GASKET RIGHT???? IM CLUELESS

This might be a long shot, but maybe one of your hoses are clogged? Is the coolant level correct? Have you bled the coolant to make sure there are no large pockets of air? Hopefully you figure it out... the engine in the Legend is excellent! The symptoms you're describing seem to me like the fans wouldn't be working properly... this might also be a stupid comment, but are the fans installed the right way? I don't know if they have any sort of method to prevent them from being installed backwards, but it's worth a shot to look into that as well.

Air may be getting into the system. Check your water return hoses. The leak could above and evaporating before hitting the ground.

u might have a bad cheap thermastat, try to drive without the thermastat at low speed if no overheating, then u should know u need a better part. good luck.

Those after market electrical fan switches are crap. Just because it's new doesn't mean it's good. I bought one from Schucks for my Pontiac grand am and I had the same issue. Overheated in traffic but worked perfect on the highway. The switch was rated at 190 but didn't switch on the fan until my car coolant was 220 or over. I figured it out by letting my car idle and monitoring the temp gauge while waiting for the fan switch to trip. My solution was to go to the dealer and pay extra for a 'factory original' fan switch.

air could be getting in ur lines there possible ripped or have a hole in them if not then ur fan is borken or not rotaing at the right speed

Check your belts for slippage,91 getting a bit long in the tooth,if the belts haven't been replaced.Think it is probably the thermostat my self. Need to use genuine parts on these beasts. What i would do is back flush the engine.Disconnect both top & bottom hoses fit external garden hose in bottom rad hose,make sure heater is turned on,wrap garden hose with cloths to prevent as much leakage as possible,turn hose on max flow & start car,leave on idle only.When it all runs clear,reassemble adding coolant first then top up with demineralised water.After burping all the hoses to get rid of air bubbles,fit genuine thermostat & fill to the line. Take for a drive turning heater on & off a few times".LET" it go cold & then recheck levels,top up as required should'nt need much. Sorry so long hope it is of help.Good luck.Gr8 car enjoy.
