Every car comes with a radiator. However, only a few know its importance and the common issues it may encounter. So here’s a short guide on the basic things you should know about a radiator.

How important is your radiator?

A faulty car radiator is the most common cause of car malfunctions. Without a functioning radiator, it is impossible to cool the engine. It is because your radiator is the cooling system of your car engine and prevents it from overheating. 

How does it work?

The car radiator pumps a coolant all over the engine block carrying the heat generated by the engine. The coolant then passes through the radiator fins, where it meets the cool air introduced by the radiator fan and your car’s grille. This cycle goes on as long as the engine is running.

What are the common radiator problems?

1. Radiator leaks

Coolant is circulated through your engine and radiator by radiator hoses. However, these hoses can sometimes wear out, causing your radiator to leak its coolant. Accumulation of water or coolant below your engine is an indication that your radiator is leaking, and you might want to check on it.

2. Low coolant level

Your radiator has a coolant level indicator, and you might want to check on it from time to time. However, the coolant level does not go down drastically. If this happens, there might be clogs or build-up of deposits restricting the coolant flow and giving you the wrong level reading. 

Leaks on the radiator body or the wear in the gaskets might also cause drastic changes in the coolant level. Remember to change your coolant following your manufacturer’s recommendation.

3. Damaged or blocked radiator fins

Too much water pressure when cleaning, any foreign material that gets stuck on your radiator fins, or improper handling can cause the fins to get bent or damaged. Damaged fins restrict the airflow to your radiator, thus causing insufficient cooling. 

4. Malfunctioning fan

Your engine overheating even under normal circumstances may be due to radiator fan failure. The fan motor may experience burnout or faulty electrical connections causing it to malfunction. Fan motor malfunctions would usually require immediate replacement.

5. Rust build-up

Your radiator is susceptible to rust and corrosion because of its metal component that continuously runs a coolant under high temperatures. An unusual discolouration in the coolant is a common indication that rust is building up in the internal walls of the radiator. 

When the coolant turns brownish or reddish, it is best to flush the coolant out and ensure that you replace it with a good quality coolant, preferably those with antifreeze, to keep your cooling system healthy.

6. Malfunctioning thermostat and water pump

Your thermostat controls the water pump, which pumps coolant to the engine. The thermostat keeps your engine operating at a certain temperature. A failing thermostat causes the engine to overheat even if the coolant level is correct and the fan is functioning. 

Conclusion

You can think of your radiator as a vital organ of your car. Keeping it in good condition means prolonging the life of your engine. Whenever your radiator experiences breakdowns, see first if it is repairable. If not, do not hesitate to change or replace it.
