A boiling engine. What are you doing about it?
Is the coolant warning light on, or does the pointer of your temperature meter suddenly turn off?
Then the engine boils or is about to do that.
In that case, put the car directly or 'ZSM' aside. But pay attention to your own and road safety.
Turn off the engine. Place the warning triangle about thirty meters behind the car and open the hood. Set the heating to the highest setting and turn the blower on full to also dissipate the heat via the heater radiator.
Allow the boiling motor to cool for at least fifteen minutes and then check the coolant level. If you do this too early, the coolant under pressure can spray out of the radiator and cause severe burns.
After the cooling period, take a cloth in your hand and carefully unscrew the cooling cap. Let the remaining overpressure escape. BUT BEWARE: the coolant is still hot.
Is there too little coolant in the system? Then top up immediately. In the event of an emergency, this is possible with normal tap water. But have your cooling system checked and filled with coolant as soon as possible.
But the inconvenience can also be caused by a faulty thermostat. This problem can be traced by feeling whether the rubber water hose becomes hot up to the radiator, if the temperature gauge indicates more than 80 degrees.
The overheating can also be caused by a broken temperature sensor. Then the sensor can be bypassed by connecting the fan directly to the battery. Is there a puddle under the car? Then top up the water and start the engine. See where it leaks and try to seal the leak with a piece of tape. After that the hose must of course be replaced asap.
A leak in the radiator can usually be solved temporarily by pushing in malleable steel or by throwing a 'stop pill' in the radiator
What with it?
Two liters of coolant, a 'stop pill', a piece of cord with two croc-clamps, malleable steel / aluminum, duct tape (the real one, no Chinaware).
Just go out with an air cooler. You don't have this kind of frills
Now write “duct tape” instead. Duck tape. That sieliekohnetape is better by the way.
