Why is my Car overheating ?

The huge expenditure resulting from an accident from car overheating is enough to throw your yearly budget off the line. Fixing the damages from overheating can be a really, really expensive affair.  You really don’t want to face some heavy damages or the possible injuries- no one does. So, here is what you may want to know about car overheating.

Have you tried touching your perfectly working car’s engine? If you have not, you better don’t. And those who have, already know the engine is quite too hot to be touched by bare hands. So working on that average temperature is normal for any engine. However, when the temperature rises above that average temperature, say around 250 F, it is a matter of concern. So we can say that, if the engine’s temperature is rising beyond that average, your car is overheating.

Every engine comes with a cooling system which helps the engine to maintain the average temperature and prevent overheating. The cooling system circulates the antifreeze- or ‘coolant’- across the engine through the ‘coolant jacket’ and in the process, the coolant absorbs the heat generated by the engine. Any inconsistency or faults in any part of the cooling system can inevitably lead to car overheating. Read on to know the common reasons why your car may be overheating.

Why is the car overheating ?

Here are some common reasons behind the car overheating. Keep an eye and check on these factors and your car and wallet shall be thanking you!

Running low on coolant

One most usual culprit behind car overheating is low coolant. As explained earlier, the cooling system helps the engine maintain the average working temperature. The cooling system needs adequate coolant to dissipate the heat generated and prevent the engine heat up. Thus, as the coolant level drops, the engine’s temperature starts rising beyond its average or say, ‘safe’ level. It is normal for the coolant levels to go down during normal running of the engine due to evaporation losses, though the rate will be quite low. You should always keep a tag on the coolant levels (check at least once a week). If you find the levels dropping fast, get the  system checked up for a leak.

Leaks in cooling system

This causes losses in the coolant levels and also results in air being pulled in and circulated within the engine rather than adequate coolant. Often, air circulation in the engine ends up in the formation of an ‘air bubble’. This causes poor circulation or even cuts of circulation of coolant.

Fan belt broken

For those cars that come with engines having a fan belt to run the cooling fan rather that the electrically run one, any breakage of the belt will result in stopping of the coolant circulation and cause chaos.

Radiator clogs

If your car buddy has run considerably enough of a distance, radiator clog can be the thing. Flush the radiator once in a year. This can keep much of the problem away.

Failed water pump

Water pump plays a significant role in the cooling system. The circulation of the coolant in the engine is greatly dependent on the water pump. So, if the water pump isn’t functioning efficiently due to any reason, you are in for the ‘heat treat’.

 

Signs of car overheating

These are the most generally observed signs of overheating that would be easy for you to spot.

  • The obvious- you will find the temperature gauge needle roaring often and quick. You can’t afford to overlook the thing if the needle is hitting the red zone!
  • The engine smelling off or different from usual.
  • Any overheating warning light signs (for the cars that have temperature warning signs).
  • You notice smoky vapour or steam coming engine or pouring out of the car hood.

You must try out any of the below given tips one any of these signs come into your notice.

The ‘first aids’ !

You can do some basic things when you notice your car is overheating. Here are some ‘first aid’ tips you can try out:

  • Turn off the cars air conditioning system.
  • Turn the heater on- it works to a great extent in transferring the heat out. Oh well, help yourself here!
  • Revving a bit to pace the fan and water pump up can be helpful.
  • Avoid using brakes.
  • If you find steam dropping out of the hood and the above tips aren’t helping much, pull over in a shaded place and toss the car’s hood up- sit back and let it cool. Warning: Do not try adding water until you find the engine cooled. Do not toss up the radiator cap.

Make sure there is adequate oil so that the engine stays lubricated. It is always better to deal off with the overheating thing at the earliest. The chances of damages and amount of repair bills would just go up with the time you overlook the heat up thing. So, now that you have a rough perspective on how to deal with it, you don’t have to let the sudden overheating rob your bank account! So Long !!
