4 Signs Your Car’s Radiator Needs Repair

The radiator is one of the most crucial parts of your vehicle to help it run smoothly. Its purpose is to keep the engine cool and prevent it from overheating. The engine uses a coolant to absorb the heat created when it’s running and transfers it to the radiator where it cools it down enough to send back to the engine. If you neglect the radiator in your vehicle enough for it to fail, it can create permanent damage to the internals of your engine.

Many people aren’t aware of the signs that your radiator needs repairing, here are 4 indications where you can easily notice if your radiator needs work done before it’s too late:

  1. Temperature Gauge – Make a habit of regularly checking the readings on the engine temperature gauge on your vehicle’s dashboard. If you notice it to be high or at the peak in the red area consistently, then the radiator isn’t cooling as efficiently as it should. It could be blocked by deposit build-up or debris stopping the correct amount of coolant getting around the radiator to cool the engine.
  2. Damaged Fins – The fins on the front of your radiator are prone to be clogged up by dirt on the road, bugs and debris such as leaves. They are also very delicate and so can easily be bent or damaged when hit by stones. Another tip is to be careful when cleaning your car. Don’t be too rough and spray the radiator with a high-pressure washer and that could move the fins around, and be gentle with a sponge wash to not bend them round. If the fins get damaged it could limit the amount of air flowing through and clog up the radiator which in turn will overheat your engine.
  3. Leaks – The coolant is usually a green colour, or sometimes it can be yellowish or pink. If you see a puddle of this fluid coming from underneath your car you have a leak. Any amount of leakage is bad and you should get a mechanic over to come to check it out for you to see what part of the radiator the leak is coming from.
  4. Rust – If any part of your radiator has rust spots then you should consider replacing it. If a piece of rust combines with the coolant it will create a thick liquid and therefore not allow the engine to be cooled down. If a part of the radiator gets too rusty it can also corrode and cause a leak.
