Checking and Maintaining Your Coolant

Okay, so you've got the right 2018 Subaru Forester coolant type. Now what? Regular checks and maintenance are key to keeping your cooling system in tip-top shape. Here's a simple guide to keep you on the right track:

Checking Coolant Levels

Checking your coolant level is a simple task that can save you a lot of headaches down the road. Locate the coolant reservoir (usually a translucent plastic container) in your engine bay. The reservoir should have markings indicating the minimum and maximum fill lines. When the engine is cold, the coolant level should be somewhere between these two lines. If the level is low, it's time to top it up. If it's constantly low, there might be a leak, and that’s a signal to take your car to a mechanic.

Regularly checking your coolant level is one of the easiest ways to ensure that your engine is adequately cooled and protected. It is recommended to check the coolant level at least once a month or before any long trips. Make sure that the engine is cold when checking the coolant level to avoid any risk of burns. If you notice a sudden drop in the coolant level, it's important to investigate the cause promptly. A leak in the cooling system can quickly lead to overheating and engine damage.

Coolant Inspection

Beyond checking the level, take a look at the coolant itself. Is it clean and clear, or is it murky and discolored? The coolant should have a bright, vibrant color, typically green or blue, depending on the type. If it looks rusty, brown, or has any debris floating in it, it's time for a coolant flush. This discoloration could indicate contamination or degradation of the coolant, which could compromise its ability to cool the engine effectively. A coolant flush removes the old coolant and any accumulated deposits, replacing them with fresh, clean coolant.

During your coolant inspection, also check the condition of the radiator cap and hoses. The radiator cap helps maintain the correct pressure in the cooling system, which is essential for its proper functioning. Check the cap for any signs of damage or wear, such as cracks or leaks. Inspect the coolant hoses for any cracks, bulges, or leaks. Hoses are prone to wear and tear due to the constant exposure to heat and pressure. Replace any hoses that show signs of damage. Regular inspection of the radiator cap and hoses can help prevent coolant leaks and maintain the integrity of the cooling system.

Coolant Flush Frequency

Most manufacturers recommend a coolant flush every 30,000 to 60,000 miles or every 2 to 5 years, but it's always best to consult your owner's manual for your 2018 Subaru Forester. Coolant degrades over time, losing its ability to prevent corrosion and adequately cool the engine. A coolant flush involves draining the old coolant, flushing the system with a cleaning solution, and refilling it with fresh coolant. This process helps remove any buildup of rust, scale, or other contaminants that can impede the cooling system's performance.

Following the recommended coolant flush interval is a crucial maintenance task to ensure that your engine is properly protected. Regular coolant flushes help maintain the efficiency and longevity of the cooling system components, such as the radiator, water pump, and thermostat. By removing contaminants and replenishing the coolant with fresh fluid, you can prevent overheating and potential engine damage. Make sure that you dispose of the used coolant properly, as it is considered hazardous waste. You can take it to a local auto parts store or a recycling center for safe disposal.
