Car Radiator Repairs – Red Flags That Should Give You Pause

While most newbie motorists may not pay particular attention to their radiator, this component is one of the most crucial auto parts for the performance of your vehicle. The radiator has the primary function of ensuring that your engine does not overheat. So how does it do this? When the engine generates heat, coolant absorbs this heat. The coolant fluid is then directed into the radiator so that it can cool off before it is re-directed back to the engine to being the process all over again. When your radiator acquires damage, this cooling process is impeded and will inadvertently affect the performance of your engine. As a result, it is imperative to spot the signs of radiator malfunction early so that other auto parts do not decline too. Below are red flags that indicate the need for car radiator repair.

Visible rusting

Corrosion on your engine and radiator can wreak havoc on the performance of your cooling system. If rust develops, it will eventually make its way into the coolant. As a result, the coolant will become compromised and start to clog the radiator. When this happens, it is judicious to have the radiator flushed, or you will end up with dirty coolant being cycled from the radiator to the engine.

Visible leaks

Another red flag that your radiator is in danger of malfunctioning is signs of coolant leaks. The coolant is not supposed to make its way out of your vehicle. And when the coolant starts to drip from the radiator, it is likely that the system has developed cracks and will need immediate replacement. Take note that leaks can occur at any time, whether you are driving your vehicle or you have it parked. Coolant leaks do not only mean that your radiator is in trouble though. A leak usually translates into decreased levels of coolant. Thus, your engine will be at a higher risk of overheating. It is essential to have your mechanic inspect your radiator to determine where the leak stems from and whether the system needs immediate replacement.

Visible sludge

Coolant that is in excellent condition should have a yellow or green colour. However, if the coolant has become contaminated, it will drastically change in colour, turning brown. Contaminated coolant is terrible for your radiator, as it means sludge is being deposited into the system. As the sludge accumulates, it solidifies the coolant, which means the engine is not receiving enough of this fluid to keep it from overheating. The moment you notice sludge inside your radiator, it is essential to have a mechanic remedy this, or you risk disrepair to both the radiator and your engine.
