Radiators & Cooling Systems

Don’t get caught in the hot sun with an overheating car.  If you notice your temperature gauge moving higher than usual or spotted coolant on your driveway, then it’s a sign your car’s cooling system needs servicing.

Radiators & Cooling Systems

Your car’s radiator plays a significant role in keeping your engine cool and your vehicle running. Your car’s engine produces a lot of heat when running, and if it isn’t continuously cooled, the heat can cause severe damage to your engine.

If you suspect a heating issue, you should get your radiator serviced by a mechanic before a potentially minor issue severely damages your engine.


Have you ever wondered how your car stays cool? This happens with the help of the radiator and other cooling systems built into your vehicle to keep you safe and prevent overheating. Over time, however, wear and tear can affect your radiator, and your cooling systems may need fine tuning to keep your car in premium operating condition. Avoid unwanted accidents or breakdowns and bring your car to us at Port Phillip Automotive in the heart of Mornington Peninsula for a thorough inspection and repairs to your car radiator.

Many motorists may not realise it, but a car radiator plays an integral role in the overall functioning and performance of your vehicle. No matter what model or make you drive, the radiator is key to safe driving and must be kept in pristine condition over the years. You can have your radiator fluid checked during your regular car services, but there are also a few warning signs that you can look out for to determine if your radiator needs professional attention.

    Radiators & Cooling Systems


    The engine of a car produces large amounts of heat when it’s running, and thus requires constant cooling from the radiator and other mechanisms. If your engine isn’t continuously cooled, it will quickly overheat, which will cause serious damage, not to mention putting the driver at risk. For this reason, regular services are recommended. If you notice any of the following signs, you should take your car to the nearest mechanic for radiator repairs. In severe cases, you may also need alternator repair since the overheating of the engine can affect your car’s alternator.

    • You notice the temperature gauge moving higher than normal
    • You suspect that the engine is overheating
    • You spot radiator coolant on your driveway


    At Port Phillip Automotive, we’re all about improving the relationship between car and driver. We help you understand your vehicle better, leading to better handling and safer journeys. With a little knowledge of your car’s inner workings, you’ll be able to care for it and see significant results on the road. Let us share some of our knowledge with you about your car’s cooling system so you can make the right decision about when to take your car to the mechanic.

    Radiator: As one of the integral parts of the cooling system, the radiator passes hot coolant through its metal fins, cools it off, then pumps it back into the car’s engine.

    Radiator Hoses & Housings: Radiator hoses transfer the coolant in the engine, ensuring consistency in the cooling process. These hoses can become brittle and crack over time, so it is vital to have them checked regularly and replaced when necessary.

    Water Pump: Responsible for pumping coolant throughout the engine, the water pump makes sure the engine remains at a favourable temperature at all times. Just like all components of your vehicle, the water pump can corrode with regular use and should be checked by a mechanic at regular intervals.

    Thermostat: The thermostat controls the coolant’s circulation rate and helps maintain a consistent operating temperature. Thermostat problems can lead to an overheating engine, poor fuel economy and increased engine wear

    Electric Cooling Fan: Another critical component in the cooling system, the electric cooling fan is controlled by the car’s thermostat and automatically helps the coolant and thermostat stay at a constant, optimal engine temperature. Make sure this fan is in good working order for best vehicle performance.

    I was down the peninsula visiting family when my car wouldn’t start one evening. Chris from Port Phillip Automotive came and checked out the car within 20 minutes, found the problem quickly and the next day had fixed it for me. Fast, reliable and great service

    My Nissan Patrol kept having engine check light come on and it would constantly go into limp mode. The car had logged several codes and Nissan told me that the car would cost approx $6000 to repair. I got a second opinion through Chris, and within 3-4 minutes he found my supposed $6000 issue, it turns it out was a loose fuel line and it was a simple fix with a $1 hose clamp. Very happy with the outcome!
