Blue Coolant Light Comes On When Car Starts

Blue Coolant Light Comes On When Car Starts: A Comprehensive Guide

Definition

The blue coolant light on your car’s dashboard is an indicator that the engine coolant level is low. Coolant is a vital fluid that helps to keep your engine running at the correct temperature. It circulates through the engine and absorbs heat, which is then dissipated through the radiator. If the coolant level is low, the engine can overheat and cause serious damage.

Types of Coolant

There are two main types of coolant:

  • Inorganic Additive Technology (IAT) coolant: This type of coolant is made with silicates and phosphates, which help to protect metal components in the cooling system from corrosion. IAT coolant typically has a green or yellow color.
  • Organic Acid Technology (OAT) coolant: This type of coolant is made with organic acids, which are less corrosive than silicates and phosphates. OAT coolant typically has a red or orange color.

Differences Between IAT and OAT Coolant

The main difference between IAT and OAT coolant is their longevity. IAT coolant typically needs to be replaced every 2 years or 30,000 miles, while OAT coolant can last up to 5 years or 100,000 miles.

Ease of Replacing Coolant

Replacing coolant is a relatively easy task that can be done at home with a few basic tools. The process typically takes about 30 minutes to an hour.

Process for Replacing Coolant

To replace the coolant, you will need the following:

  • New coolant
  • Funnel
  • Drain pan
  • Wrench
  • Gloves
  1. Park your car on a level surface and allow the engine to cool down.
  2. Open the hood and locate the coolant reservoir.
  3. Place the drain pan under the radiator and open the drain plug.
  4. Allow the coolant to drain out completely.
  5. Close the drain plug and add new coolant to the reservoir until it is full.
  6. Start the engine and let it run for a few minutes to circulate the coolant.
  7. Check the coolant level again and add more coolant if necessary.

Advantages of Replacing Coolant

Replacing coolant regularly has several advantages, including:

  • Prevents engine overheating
  • Protects metal components from corrosion
  • Improves engine performance
  • Extends the life of the cooling system

Disadvantages of Replacing Coolant

There are no major disadvantages to replacing coolant regularly. However, it is important to use the correct type of coolant for your car and to follow the manufacturer’s recommended replacement schedule.

How to Check the Coolant Level

You should check the coolant level regularly, especially before long trips. To check the coolant level, follow these steps:

  1. Park your car on a level surface and allow the engine to cool down.
  2. Open the hood and locate the coolant reservoir.
  3. The coolant level should be between the "MIN" and "MAX" marks on the reservoir.
  4. If the coolant level is low, add more coolant until it reaches the "MAX" mark.

What to Do If the Blue Coolant Light Comes On

If the blue coolant light comes on while you are driving, it is important to stop the car as soon as possible and check the coolant level. If the coolant level is low, add more coolant until it reaches the "MAX" mark. If the coolant level is full, there may be another problem with the cooling system. In this case, you should have the car towed to a mechanic for diagnosis and repair.

Conclusion

Replacing coolant is a relatively easy and inexpensive way to maintain your car’s cooling system and prevent engine overheating. By following the steps outlined in this article, you can replace the coolant in your car yourself in about 30 minutes to an hour.
