The car was overheating then it shut down on the freeway. now it makes a funny sound when u try to start it


If your car to overheat, it is very likely to be for any failure or some electrical defect in the cooling system. With the engine off, check for water leaks in the engine or under it, it could be internal leakage in the gasket, if this happened, I suggest you immobilize the car, but could damage. review of water and coolant levels if they are in the correct, it could also be a fault in the thermostat, water pump or the fan on relay.

Overheating is due to, well, the coolant in the cooling system getting too hot. In a normally operating engine, this should never be a problem. First, check that the coolant level is correct. If it is correct, I would suspect a problem with the thermostat. When the engine is cold, the thermostat closes off coolant flow through the engine until the coolant reaches a pre-determined temperature. When that temperature is reached, the thermostat opens to allow the coolant to circulate at that exact temperature.

Thermostats are known for failing and either not opening or not opening enough at that pre-determined temperature. This causes coolant to get trapped too long in the engine coolant chambers, heating it beyond limits, causing the engine temperature to increase and possibly overheat.

If my Maxima was overheating, I would check the coolant levels and then possibly replace the thermostat. It usually is no more complicated than that.

Keep in touch.

The car keeps overheating and the coolant and water level are fine. i dont know what else it could be


Thermostat could be stuck closed - put your hand on the hoses (after the engine has been running a bit) and check if one is cold. If one is cool to the touch - the water pump has failed - or the thermostat is failed (stuck) shut (supposed to fail open).

Radiator fans inoperable - check the fuse and relay.

Head gasket failure - would need to be checked via piston pressure check.

Overheating


BELOW list is compiled from our staff with a more likely cause of overheating.

Radiator cap failure. Must be able to handle 15 psi tested.
Antifreeze failure. Has the coolant been tested or changed in the last few years?
Does the cooling fan
cycle?
Clogged radiator.
Thermostat
failure. Thermostat's do fail, you you have any memory of changing it?
Head gasket. This problum you would tend to never be able to get the air out of the radiator, lots of small bubbles. if this is your problem seek provisional help this problem only get worse not better.

Hope these tips guide you to the solution to your problem

Random Overheating Problem on Peugeot 206


It sounds like your thermostat has gone bad and sticking close, Replace the Thermostat and Antifreeze. When replacing the thermostat, buy a fail safe thermostat so you will not have a overheating problem when the thermostat fails. Good luck and hope this helps. Keep me posted, be glad to help.
