WHen a car overheats its alwasys one of these problems,

  • thermostat failing in the closed position.
  • the fan not working properly.
  • radiator semi clogged.
  • the water pump would cause this too but usually you will see leaking from the pump itself.
  • low coolant, but it looks like you have checked that.

My coolant isnt circulating,i have heat but low power and high car will overheat if I climb hills.

Hey Rayna,,, if you are sure the coolant is not circulating..??.. Then the water pump is no longer functioning.. OR....the coolant passages have partially clogged up.. When you replaced the thermostat , you should have reversed flushed the entire coolant system, check the radiator hoses for wear (they wear out from the inside), flushed the radiator completely..... Do the complete flush and check the hoses.. refill and see how much better it does..

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.

Took out the thermostat, replaced the radiator, the water is circulating in the radiator but it is still running hot. what do i do next?

Overheating can seriously damage a car's engine if left unchecked. Although overheating simply means that a car's engine temperature exceeds normal operating temperatures, the causes of overheating are varied. What follows is a brief list of some of the most common causes of engine overheating.

    Faulty Radiator
  1. A car that overheats will often have a faulty radiator. A radiator is responsible for cooling hot engine coolant that picks up heat from inside a car's running engine. A radiator "radiates" the heat from engine coolant out into the outside air. A faulty radiator loses its "radiating" effects and allows engine coolant to become overheated, thus rendering it ineffective at adequately cooling and engine.
  2. Faulty Water Pump
  3. A faulty or malfunctioning water pump prevents adequate engine coolant flow and can cause a car to overheat. A water pump serves to pressurize and propel engine coolant throughout a car's engine and radiator to increase the heat-reducing capabilities of engine coolant. A faulty water pump loses its ability to adequately pump and propel engine coolant, and can cause a car to overheat.
  4. Coolant System Leaks
  5. A leaky engine coolant system reduces the level of circulating engine coolant, which increases engine temperature and leads to engine overheating. Radiators, water pumps, and coolant system hoses and seals--all of these coolant system parts can develop leaks, which can result in low coolant levels and engine overheating.
  6. Faulty Thermostat
  7. A car thermostat regulates the flow of engine coolant. A thermostat is a heat-sensitive valve that opens when a car engine reaches a set operating temperature and closes when a car engine is cold and warming up. If a thermostat gets stuck in the closed position, coolant will be prevented from reaching the engine, which will quickly lead to engine overheating and potential engine damage.
  8. Low Engine Oil Level
  9. Engine oil, in addition to lubricating an engine's internal parts, helps to keep engine operating temperatures reduced by eliminating friction within the engine. If engine oil levels are low, friction and heat build up inside an engine, a condition that causes increased engine operating temperatures and can lead to engine overheating.

My car is not hot air and the antifreeze liquid inside the cab beside the driver its a mazda mx3 1992

If no heat from heater its likely low on coolant, and antifreeze in cab on the floor means its probably leaking from the heater core.

My 1997 Dodge Intrepid overheats. I've replaced the thermostat, and it continues to overheat. I noticed adjacent to one of the radiator hoses, a ribbed hose that is split. Could this cause the car to...

Now that you've eliminated the thermostat, it could be a number of other things. Don't drive the car too far until you've fixed the overheating problem - overheating can destroy an engine.

That split ribbed hose you see is plastic wire loom - it carries and protects electrical wires, and is not the cause of overheating.

1. Low coolant level
2. Radiator hose split/cracked, causing low coolant level.
3. Head Gasket - leaking, causing low coolant level
4. Thermostat - stuck closed (you eliminated this possibility)
5. Radiator cap - worn/damaged
6. Radiator fins - obstructed by debris/cardboard
7. Water Pump belt - missing/broken
8. Heater Core - leaking, causing low coolant level
9. Intake Manifold Gasket - leaking, worn, damaged
10. Radiator Fan Relay - faulty
11. Radiator Fan Blade - broken, missing
12. Radiator Fan Sensor/Switch - faulty
13. Water Pump - leaking, causing low coolant level
14. Radiator Fan Motor - faulty

My primary suspects would be Rad Fan Relay (#10), and
Rad Fan Switch (#12).

Honda accord idles high and low no heat inside

First thing you have to do is check the coolant level. It is possibly very low on anti- freeze, or frozen up from the anti freeze not being strong enough.

1992 mazda mx3 is overheating. checked thermostat seems to be working. Noticed that the heater started acting up a few days before it overheated......Heater works randomly, seems like you start the car...

Check your coolant. If the coolant is low, you won't get heat in the cabin. Make sure that the fan is turning on as well. Check coolant sensors also. Good luck!

Over heating

overheating can be caused by thermostat stuck open or cooling fan not working . . can also be caused by low coolant level or defective or blown head gasket
