When driving down highway only, it overheats? When running steady, I take it you mean, sitting idling? If it's only overheating at highway speeds, and all else has been checked out & is o.k., I'd take a close look at rad hoses for soft spots (easy to squeeze) that may be causing hoses to collapse at highway speeds & restricting flow of cooling system. Another thing to try is, turn your heater on high fan & high temperature when it starts to heat up & see if temperature gauge goes down (cooler) at all. If it does, then rad not doing it's job properly.

You have to check the coolant level in the radiator when the engine is cool.Best time is morning. Open the radiator cover and put the coolant in and start the engine and wait till the engine is hot and thermostat is open .Then your water level may go down and get vented properly. Please top up again . add water to you reserve tank also up to the mark full .Now try again .Best of luck.If you have problem please come again. Please rate the answer.

Overheat after waterpump replacement


Did you change the thermostat? If not it may be the cause. You can check the thermostat by removing it and immersing it in hot water. If it is working it will open. The thermostat is usually located under the upper radiator hose.

Water pump is bad because overheats when engine is running at low speed, and good at high rev. The water pump impeller can not push the coolant with the required pressure.

My 98 ford contour keeps overheating i just replaced the radiator and the water pump. And there is no water in the oil. The fans work but it still overheats . What else could be causing it to overheat?


I can't believe anyone would replace the waterpump without also replacing the thermostat. Once overheated, a thermostat is no good anymore. It must be replaced.

But that is not the only possibility. You could have a bad head gasket, without having oil in the water. Only a pressure check can tell. You could also have a collapsing lower hose, as water pump suction causes it to pinch off. You could also have an air bubble from not bleeding it properly when refilling. You could also have a loose waterpump belt. You could have put in the wrong waterpump, as the type for normal V-belts runs the opposite direction of the type for serpentine belts.
There are many more, but that is all I could immediately think of.

The cooling fan should run continuously when the A/C is on. If it does then I suggest you drain and flush the cooling system, and replace the thermostat. Fill it with a fresh supply of a 50/50 mix of antifreeze and distilled water.

Even after replacing the radiator, thermostat and


The problem with overheat is due to poor coolant circulating. The main culprit is the Radiator. When the radiator is clogging up, coolant can't be circulating. The stagnant coolant inside the engine water jacket keeps absorb heat from combustion chambers having no way to dissipate the heat then the engine is overheated. You can test the water pump by removing the thermostat, then hooking everything back. Open the radiator cap, then turn on the engine to see if water flowing down to several small tubes inside the radiator. If water can't go down fast enough to cause over flow at radiator opening then your 90 Legend Radiator already got clogged up. Replace with a new radiator, not even a rebuilt one. Good luck.

Changed entire cooling system and still overheats


The overheat sounds like an air pocket in the cooling system there are two bleeder screws located on top of thermostate hosing and 1 on the metal pipe just above the water pump I believe they are 7mm. with the radiator cap off and the car running slowly open 1 bleeder at a time just crack it loose until you get a steady stream of coolant make sure to keep the level in the radiator up. be carefull coolant may be hot! when you take the oil cap off you are creating a big vacuum leak thru the PCV (positive crankcase ventalation) system this is normal for this car to surge or die.
