How to Check and Maintain Coolant Levels on Your Subaru Baja: A Beginner’s Guide

As a Subaru Baja owner, it’s important to understand the basics of car maintenance to keep your vehicle running smoothly and safely. One critical aspect of car maintenance is checking and maintaining coolant levels. In this beginner’s guide, we’ll cover everything you need to know about coolant and the steps to check and maintain coolant levels in your Subaru Baja.

What is Coolant and Why is it Important?

Coolant is a liquid that regulates the temperature of the engine in your Subaru Baja. The coolant flows through the engine, absorbing heat and transferring it to the radiator where it is cooled down. Without proper coolant levels, your engine may overheat and potentially cause severe damage to your vehicle.

In addition to regulating temperature, coolant also acts as a lubricant, which helps prevent corrosion in the engine. By maintaining proper coolant levels, you can prevent engine damage and ensure that your Subaru Baja runs smoothly.

How to Check Coolant Levels in Your Subaru Baja

It is recommended to check your coolant levels every month or before long trips. Here are the steps to check coolant levels in your Subaru Baja:

  1. Park your car on a level surface. Ensure that your car is in park and the engine is turned off.
  2. Locate the coolant reservoir tank. In a Subaru Baja, the coolant reservoir is located on the left side of the engine compartment, and it’s marked with a yellow cap.
  3. Check the coolant level. The coolant level in the reservoir tank should be between "Full" and "Low" markings. If the level is below the "Low" marking, you need to add more coolant.

It’s important to remember, never open the coolant reservoir tank when the engine is hot, as the pressure from the hot coolant may cause burns.

How to Add Coolant to Your Subaru Baja

If your coolant levels are low, here are the steps to add more coolant to your Subaru Baja:

  1. Purchase the correct coolant. It’s important to check the owner’s manual for the recommended type of coolant for your Subaru Baja.
  2. Open the coolant reservoir tank. Wait until the engine cools down, then open the coolant reservoir tank cap.
  3. Add coolant. Add coolant slowly until it reaches the "Full" marking on the reservoir tank.
  4. Secure the cap. Secure the coolant reservoir tank cap back in place.

If your coolant levels continue to drop even after adding more coolant to your Subaru Baja, it may indicate a leak. In this case, it’s recommended to get your vehicle inspected by a professional.

When to Replace Coolant in Your Subaru Baja

It’s recommended to replace your coolant every 30,000 miles or every three years, whichever comes first. If you’re unsure when your coolant was last replaced, you can check the color of the coolant. Fresh coolant is typically bright green or orange, while older coolant may look rusty or brown in color. If the coolant appears dark, it’s time to replace it.

In addition to coolant replacement, it’s also recommended to flush the coolant system every 60,000 miles or every five years. A coolant flush helps remove any built-up dirt or debris from the system, which can improve the overall performance of your Subaru Baja.

Q: Can I add water instead of coolant to my Subaru Baja?
A: While adding water may temporarily increase the coolant levels in your vehicle, it’s not a recommended long-term solution. Water alone does not offer the same level of corrosion protection as coolant and may also freeze in colder temperatures, causing further issues.

Q: Is it normal for the coolant levels to drop?
A: A small drop in coolant levels is normal due to evaporation over time, but significant drops in coolant levels may indicate a leak in the system.

Q: Can I replace my own coolant?
A: Replacing coolant in your Subaru Baja is a relatively simple process and can be done at home, but make sure to follow the instructions in your owner’s manual and use the recommended coolant type for your vehicle.


Checking and maintaining proper coolant levels in your Subaru Baja is a crucial aspect of car maintenance. By following these simple steps, you can prevent costly engine damage and ensure that your vehicle runs smoothly. Remember to check your coolant levels regularly and replace your coolant and flush the system as recommended in your owner’s manual.
