Blow on it. If that doesn't work, turn the engine off.
Check the radiator fan operation.
The radiator could be plugged or a couple of the internal coolant passages in the engine block could be plugged. Try back-flushing the radiator and the engine and see if that helps.
The antenna mast is stripped.
Your thermostat might be stuck open. Does the radiator cap get hot after running the engine for 10-15 minutes? If not, replace the thermostat.
which light is blinking??need more info
Either: 1) Thermostat is bad or 2) Radiator is clogged or 3) if your losing fluid or hearing a noise, check your water pump. If your not losing fluid or hearing a noise, the service the radiator by having it flushed. If this doesn't solve your problem, then change the thermostat. If your still having the problem then your radiator may need further service or even replacing. I'm having the same issue right now. I'm replacing my thermostat next. If it still is running hot, I'm going to take the radiator out and have it serviced. Good luck! And remember, DONT let the temperature get in the red!!
I would start off with replacing the radiator cap if it don't have one then the cap on the refill tank ,this may fix your problem .
How's the water pump?
carries water from and to the engine to the radiator for cooling, there are 2 and contain hot water when the engine is running and will still be hot and pressurerised for an hour after the motor is shut off.
If an engine light is still on after replacing a fan's radiator sensor in a RFW engine the coolant sensor should also be checked. If the coolant sensor is bad it will send an error code to the car's computer.
No you dont have to. All I did was was pump the brakes with the car running
try replacing radiator cap, it may be stopped up .
