Volvo S80 Radiator

Common Issues with the Volvo S80 Radiator

By design, radiators pump a mixture of water and coolant into the engine block to absorb any excess heat and dissipate it efficiently. Also, they help your car's A/C system regulate its temperature. The Volvo S80 radiator is built to ensure that your engine is cool at all times. But just like any other car part, it is prone to damage and wear. Leaks, broken fins, and corrosion can lead to extensive and costly repairs if left unattended. Here are some common concerns encountered with the Volvo S80 radiator, along with the possible reasons behind them:

Coolant leaks

At first, you may think that the bright pool of liquid on your garage floor might be a leak from your vehicle's A/C system. Usually, coolant leaks come from damaged or cracked radiators. It's actually tricky to detect or determine where the coolant leak originated until it's too late. You can start by inspecting your radiator for signs of leaks, and try to fix it immediately. Worn-out tubes and hoses should be replaced immediately. It's also recommended that you bring your car to a specialist who can perform a pressure test to determine if the leak is from your radiator or from somewhere else.

Dark and murky

That's how radiator sludge looks like; dark and murky. Radiator sludge is usually caused by rust or debris, contaminating the radiator's automotive coolant. Corrosion or rust also results to flaking, which makes the sludge thicker, and more destructive. When sludge starts to form on your vehicle radiator, it will inhibit cooling, destroy the radiator's fins, and contaminate the engine block. Once you detect sludge in your radiator, purchase a new one, and replace it immediately.

Engine overheating

When you're experiencing engine overheating, it's a sign that you're having radiator problems. Since a radiator is designed to circulate coolant through your car's engine, if there are blockages or leaks in the radiator, it may fail to cool your engine completely. You will basically notice a higher-than-normal temperature on car's temp gauge. A routine check-up is needed to determine the root cause of the engine overheating.

  • Some Tips on How to Maintain Your Volvo S80 Radiator 27 February 2013

    Without your Volvo S80 radiator, your car's engine will overheat and cease to operate. Considered as one of the major components of your car's cooling system, the radiator pumps coolant into your car's engine-this absorbs heat from the different engine parts and effectively dissipates it. But unknown to many, small dust particles and rust can build up in the car's radiator, clogging up the cooling system's essential elements. This will lead to expensive repairs or a damaged engine. Keeping your radiator well maintained isn't that difficult. Here are some tips to help you keep it in good working condition:


    Fill it with the right fluid.


    Using the right coolant or antifreeze for your radiator is very important. Glycol-based coolant or antifreeze is the top choice of most drivers and mechanics. Now, depending on location, the right mixture of water and coolant is really critical. If your place has a warmer climate, equal amounts of water and antifreeze are needed to effectively cool your engine. For colder climates, more antifreeze is needed in the mixture. Never use coolant as the sole fluid for your radiator. Pure coolant or antifreeze can damage your radiator as well as the neighboring engine block. Always mix water in the solution to dilute the coolant's innate potency.


    Flush the fluid from time to time.


    Debris and dirt that accumulated inside your car's radiator can block the antifreeze and water from circulating properly throughout the cooling system. Also, antifreeze can be acidic over time and can corrode the radiator's fins. Perform a radiator flush at least twice a year to remove debris, dirt, and old antifreeze to keep your radiator in tip-top shape.


    Purchase a new cap and change the old one.


    Replacing your radiator's cap is part of the radiator's maintenance routine. Over time, the cap gets damaged, resulting in coolant leak. It's best to change your radiator cap when you're flushing and changing your radiator's antifreeze.


    Check the hoses and fittings for any sign of leaks.


    The radiator's hoses are usually made of rubber, which can get brittle after a couple of years. As your radiator's hoses wear out, they develop small holes that allow for coolant to leak. Always inspect your radiator's hoses for damage and replace worn-out hoses immediately. Secure all hose fittings when installing new rubber hoses.
