No the coolant cant , but the eight years of dirt that its left behind inside the cooling system sure can , id bet that the radiator is a little plugged with dirt now , they do sell flush and fill kits at the auto parts store , and there not expensive

Coolant can wear out, so they say. But when tested? First check.. When you turn on the A/C and it is working. The high speed engine/radiator fans should/will come on. If they don't look to the fuses first, then relays and wiring( could be a resistor in there also, I work on to many different ones). Worse case is the PCM.

Car overheating causing fluid to come out of the reservoir

Change your thermostat. Ensure that your radiator fan is running at idle. See if your heat blows warm or not when the engine is warmed. if the heat is clod, then you have no water circulation in your engine. either the thermostat isnt opening up, or there is a blockage in your cooling system.

Having over heating problems with my 2000 taurus it does it most with def. or air cond. on full blast did find small leak at water pump where it bolts to block. replaced both cooling fansand,the thermostat...

No!!!!...Yes!!!
No, the sending unit is working right.
Ideas? Yes, I think the problem is the water pump. Don't drive it overheated till you get a new water pump or have it inspected. You say it's a small leak where it bolts to block, but maybe it's the "weep hole" on bottom of pump leaking, meaning the internal seals on the pump have failed. If so, it won't be a small leak, it will leak all the time engine is running. A lot may be swept away by air, or by evaporating. Check it out. That's a likely cause of overheating.

Over heating

I assume you have checked the cooling system to ensure that first, that it is completely full of coolant (not just the overflow tank) with no air locks and second that there are no leaks anywhere and the radiator cap is in good condition. The heater hoses and those pesky little bypass hoses in the cooling system tend to go hard and split if they are over 10 years old, allowing coolant loss. Those spring type hose clamps tend to be less effective in clamping as the hoses become hard. Worm drive ones are the best to use.

If there are no leaks or air locks, the over heating could also be caused by a clogged radiator (more than 15% restriction in the radiator flow capacity will cause overheating problems), a faulty water pump or a faulty thermostat.

If there are no leaks and water pump and thermostat are working correctly, but undetected loss of coolant once the engine heats up, then it could indicate a problem with the head gasket (Usually caused by allowing engine to become excessively overheated when cooling system has run dry and warping the head) allowing very hot high pressure combustion gases into the engine water jacket, which super heats the coolant in the engine block, which then boils off, and is released via the cap. If the head gasket leak is bad enough it will allow coolant into the combustion chambers which will produce white steamy smoke in the exhaust and allow coolant to get into the sump while the engine is stopped. This is indicated by a white oil and water emulsion on the dipstick.

If unsure take vehicle to a cooling system specialist and have them do a pressure test and more thorough diagnosis.

Will car run hot if oil change is needed

no, and oil change will not stop the car from getting hot,,, check to see if your cooling fans are coming on, if not, check fuses and relays, check coolant level

2002 kia sportage temp gauge runs hot while driving

Cheak to see that the coolant fan is operating with the A/C turned on. The fan has to work to help the engine stay cool and help the A/C. When you apply heat on the control it acts to reduce the coolant temp. You will have to get the coolant fan operation checked. This can be :fan motor, fan relay, temp sensor and computer. Good luck

1998 caddy sts over heating and blowing cold air when heat is on

sounds like it might be low on coolant. Low coolant levels will stop the flow and circulation to the heater core, and also might be the cause of overheating
