Quick Answer: How Important Is Coolant For Your Car??

Why Antifreeze is so important for your vehicle this winter.

Antifreeze has the capability to also raise the boiling point of the engine coolant in order to prevent it from overheating.

Not to mention it can also protect your engine from corrosion, aid heat transfer and prevent scales from building up.

What happens when you run out of coolant?

If you run out of coolant, and continue to operate the engine for a significant period of time, it will cause serious harm to the engine. Among the first things damaged is typically the heads and head gaskets. If you really push it, you could damage the block, seize the engine, or melt a hole in a piston.

Can I drive my car with low coolant?

If you do not have any leaks, then your coolant is most likely getting burned and/or going into your oil. Low coolant will cause overheating and can cause stress on the water pump. Low coolant that is topped off can cause overheating due to trapped air in the system. Any overheating can cause cracks or warping.

How long does coolant last in a car?

Consult your owner’s manual for the recommended change interval. Most guidelines suggest flushing your cooling system and replacing conventional coolant every 1 to 2 years. Extended life antifreeze can last up to 5 years. To test whether your current antifreeze/coolant is still effective, use an antifreeze tester.

Can I just add coolant to my car?

If the coolant level is low, add the correct coolant to the reservoir (not the radiator itself). You can use diluted coolant by itself, or a 50/50 mixture of concentrated coolant and distilled water. When coolant rises to the cold fill line, replace cap and tighten it until you feel it click.

How often should I put coolant in my car?

Many service shops, though — including some at dealerships that sell cars with “lifetime” coolant — say you should do it more often than the maintenance schedule recommends, such as every 30,000 or 50,000 miles. A 50/50 mixture of antifreeze and water is the standard coolant mix used in vehicles.

What are the signs of low coolant?

Symptoms of a Bad or Failing Coolant Level Sensor

  • Coolant Light stays on. One of the most common symptoms of a faulty coolant level sensor is a Coolant Level Light that stays on.
  • Low coolant. Another symptom of a problem with the coolant level sensor is low coolant.
  • Engine overheating. The engine overheating is another indicator of a problem with the sensor.

What happens when your car runs out of coolant?

Place a cloth over the radiator cap to protect your hand, and tilt the cap away from you as it opens. Refill the cooled radiator with your spare coolant or water. Do not pour cold water into a still-hot radiator — it could cause the engine block to crack due to the sudden change in temperature.

Why is my car using a lot of coolant?

This happens because of evaporation from the reservoir. Problematic situations may arise if there is a loss of too much coolant within a short time. This is often indicative of problems such as leaks, the inability of the radiator cap to hold pressure, or a highly heated cooling system.

Does it matter what coolant I put in my car?

Well, you use the coolant that is specified in your owner’s manual. If you just need to top it up, the recommendation is still the same, however it is unlikely to cause any serious problems if you add a litre of a different type of coolant, as long as you follow the manufacturer’s maintenance schedule.

Can coolant run out?

Running out of coolant/antifreeze won’t necessarily cause instant damage though, depending on your car. This uses the cooling system’s thermostat to kill power to the engine when the temperature reaches a certain point, and means that the car can’t be restarted until it has cooled down sufficiently.

What engine coolant should I use?

A general guide to antifreeze

Cars made after 1998 normally need antifreeze that uses silicate-free, organic acid technology (OAT). These types of antifreeze offer better corrosion protection so that parts don’t need to be changed as often.
