Blocked radiator, low on coolant, stuck thermostat, air in cooling system
yes. but there are several other things that can cause it to overheat. not enough coolant, bad belt, radiator blocked, bad thermostat,bad water pump to name a few.
If you're absolutely sure the radiator fan is working properly, have the radiator flow tested. Also, check the thermostat. It may be partially blocked.
Inoperative cooling fan(s) Bad thermostat Bad fan switch sending unit Bad fan relay Blocked radiator cooling tubes (internally)
broken thermostat; blocked hose to radiator or hole in hose; leak in radiator; etc..
The car eventually will overheat and the engine will fail either to overheating or seizing up.
AnswerBecause the engine cooling fan does not work properly or does not work at all.There are many reasons which may cause Engine overheat. the above is also one of them.Loss of coolantloss of coolant because coolant leaks from anywhere on the cooling system.Loss of coolant because radiator cap is broken and will cause overheat.Loss of coolant because radiator cap pressure is less than the required.Loss of coolant because compression leak in to the cooling system.Radiator internally blocked. (Heat exchanger blocked, if equipped)Radiator externally blocked. (Air flow blocked)Engine Overloaded (engine can be overloaded because of loss of power due to malfunction of some parts, in this case there must have other symptoms).Thermostat does not direct water circulation to the Heat Exchanger.Engine mechanical condition is not good (Power balance)Engine ignition timing is retarded.After a repair Engine started to overheat.(AC or Radiator fan is rotating wrong direction, polarity changed)
Either the radiator is blocked, or the thermostat is stuck closed, or the water pump has failed.or it just needs water.
change th radiator it must be blocked feel th radiator shoud be evenly hot.
Possible causes: (1)insufficient coolant in the system (2)water pump drivebelt defective or not adjusted properly (3)radiator core blocked or radiator grille dirty and restricted (4)thermostat faulty (5)fan blades broken or cracked (6)radiator cap not maintaining proper pressure.
1 insufficient coolant in the system . 2 water pump drivebelt defective or not adjusted properly . 3 radiator core blocked or radiator grille dirty and restricted . 4 thermostat faulty . 5 fan blades broken or cracked . 6 radiator cap not maintaining proper presure .
Could be many things. Rad., Fan, thermostat, fan sensor, water pump, blocked passages.
Low coolant, stuck thermostat, blocked hoses.
Overeheating is usually caused by a bad thermostat, blocked radiator or leaking headgasket.
Assuming fluid is not lost, and thermostat is not sticking, and water pump is working, and radiator not blocked, must be electric fan not cutting in. I think its switched on by a sensor on the block. Check cut in of electric fan. IF thats working, must be blocked or ineffective radiator.
It could be any number of things, but I'd check for bad fan relay or fuse, sticking thermostat, blocked radiator or blown head gasket.
Checking your radiator always
Fan clutch faulty. Fan shroud missing or broken. Radiator air flow may be blocked from outside with debris (leaves and stuff).
Have you checked the thermostat... Sound like a blocked radiator .................PS
If you have any questions, pull both radiator hoses and run water into one end. If you can get water to flow as fast as the hose can send it, you probably don't have a blocked heater. Also check the thermostat. A stuck thermostat can cause an engine to overheat. An easy check on a thermostat is to drop it in a pan of water then bring the pan to boiling. The thermostat should open a little before the pan starts to boil
No, it is not. It indicates that there is something wrong with the engine's cooling system. A car, even one as old as a 1993 model, should not overheat even in very hot weather. You should check that there is enough coolant in the system, and that the radiator cap is holding pressure properly. Replacing the radiator cap is a good first step, and should be relatively inexpensive ($10 at an auto parts store). You may also need to get a garage to check the thermostat and the radiator, to make sure that the thermostat is working and the radiator is not blocked.
Thermostat, blocked radiator, leaking hoses, rusted impellers on the water pump and the worst possibility, a leaking head gasket/cracked head.
All sorts of thing can.. Low oil, low coolant, blocked radiator, stuck thermostat, running too lean on fuel... If it just suddenly started to do it and the levels are ok then check the thermostat.

Or, if everything else is operating properly, it could be the thermostat or a blocked radiator, but I'd focus on the thermostat first. Be certain that the engine is at normal operating temperature when looking to see if coolant is circulating. A properly operating thermostat will prevent the circulation of coolant while engine temperatures are below operating temperature.
