Subaru Forester Radiator

Caring for Your Subaru Forester Radiator Like a Pro

As you drive, the parts inside your engine create friction against each other, leading to heat generation within the system. But your engine only works so well within a certain temperature limit. When too much heat circulates within the engine, overheating may cause your vehicle to stall. To prevent this, you need to keep your Subaru Forester radiator in flawless condition. Here are a few maintenance habits you can follow:

  • Flush your vehicle's radiator fluid periodically.

Being the most crucial part of your car's cooling system, your radiator contains the key to alleviating excess heat from the engine—the radiator fluid. Dirt and other contaminants can accumulate in the fluid over time, and with continued use, this fluid can become acidic. That is why it's ideal to change the radiator fluid every 24,000 to 36,000 miles, or every 24 to 36 months.

  • Use the right cleaning agents when removing sediment from the radiator.

When cleaning your radiator's coolant system ducts, avoid using bleach or vinegar. Keep in mind that the radiator's body is made up of thin aluminum material. Applying bleach or vinegar on it could easily damage the frame and weaken it. Use only safe cleaning solutions such as aftermarket products made specifically for radiators.

  • Choose an antifreeze that offers rust protection.

New anti-freeze products available in the market come with additives that help prevent rust and buildup. Get one that offers protection against rust and foam so that the system can run efficiently. Just remember to keep air out of the system whenever you fill the radiator with new anti-freeze. Bleed the air from the system first by leaving your car in idle with the radiator cap removed and the heater turned to max.

  • Have your car radiator checked by an expert mechanic.

Although you can perform a DIY examination of your vehicle's radiator, it's still best to consult with an experienced mechanic. They go beyond your usual checkup, and use pressure tests to see if there are leaks in the system. It's also good to have them assess whether it is about time to have your radiator fluidflushed.

  • Early Signs of a Failing Subaru Forester Radiator and How to Deal with Them

    Getting your car radiator fixed is one of the most tedious tasks you have to deal with as a driver. Its role in your vehicle's cooling system makes it a vital component and must not be ignored if found faulty. At times, it is not the radiator that has a problem, but some other parts of the car's cooling system. To investigate if it's really a damaged Subaru Forester radiator that's causing the trouble, here are a few symptoms you can look for and what to do with them.

    Rust in the radiator

    If you notice rust forming on the radiator's exterior, then you can easily remove it with sandpaper or a stiff brush and some paint and varnish stripper. However, if the rust has built up inside the radiator, then simple repair tips would not solve the problem. The rust inside will eventually eat away your car's radiator and lead to breakdown.

    What you can do is to flush the radiator with aftermarket flush solutions. Grab one that gives added protection against rust and foam so that you can extend the radiator's lifespan. Once completely flushed and clean, pour in the anti-freeze and distilled water. This should make your radiator as good as new.

    Radiator leaks

    Getting a radiator fixed is difficult as it is, more so if it is a leakage problem. Many factors can cause a radiator to leak, but the first thing you should do is to trace where the leakage has developed. Dry the radiator entirely to make it easier to find the source of the leak. Radiator spills usually come from either a small hole inside the radiator, or a leak from a hose or a joint. To prevent leakages, it's good to examine your radiator when you have time or at least once a week. Check your radiator's coolant level before going on long trips and bring with you at least a liter of distilled water for any road emergency that may happen.

    Overheating engine

    When your car overheats, the first thing that you normally inspect is the radiator. The overheating may be caused by empty or insufficient coolant level, damaged auxiliary fans, broken hoses, or worst, a busted radiator. To validate which part is causing the trouble, park your vehicle in a safe area and open the hood. Once the engine has already ventilated, look for the auxiliary fans to see if they're still working. Then, search for possible leaks in the coolant hoses. If there is no leak in the system, check the coolant level in the reservoir; be sure you don't open the engine radiator cap. Pour in water or coolant if needed. If the overheating persists, contact a mechanic or a service center nearest you.
