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:
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.
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.
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.
