We recently welcomed a 2008 Ford Transit turbo diesel into the workshop at Round Men Automotive, trusted Toronto mechanics known for helping local drivers keep their vehicles running reliably. This Transit had lived a long and hardworking life, clocking up an impressive 480,000 kilometres.

Despite the high mileage, the customer reported no signs of overheating, no warning lights and no loss of performance. The vehicle was simply booked in for a routine service—a great reminder of why regular maintenance is essential, even when a car seems to be behaving perfectly.

Given how many Transits in Toronto are used for delivery runs, trades and frequent short trips, cooling system health is especially important. Stop-start driving and long hours on the road can place extra load on components like radiators and hoses.

During the service, our technicians carried out a standard cooling system inspection, which includes:

A visual check of hoses, coolant levels and external leaks

Assessment of cooling performance during warm-up

System testing to confirm even heat distribution

Using the heat gun, the team noticed significant temperature variation across the radiator, a sign that coolant wasn’t flowing as it should. As shown in the photo above, a section of the radiator was heavily deteriorated—an indication that it was likely the original radiator from 2008.

Internally, sludge and scale can build up over time, restricting flow. Externally, age and corrosion gradually weaken the core. Even though the Transit had “never run hot” according to the owner, this radiator was no longer able to efficiently manage engine temperature.

If left unaddressed, the engine could have eventually faced:

Catching the issue during a routine service prevented a costly engine repair later.

To protect the engine and restore proper cooling performance, the team at Round Men Automotive carried out a radiator replacement. A high-quality radiator was installed to match the specifications of the Ford Transit turbo diesel, ensuring the cooling system could once again operate at full efficiency.

While completing the repair, our technicians checked related components such as:

This ensures the rest of the system won’t place additional strain on the new radiator.

With the replacement completed, the Transit now runs at stable operating temperatures, providing better long-term reliability and safeguarding the engine from future overheating issues.

As an independently owned Repco Authorised Service centre, Round Men Automotive uses reliable parts backed by a nationwide warranty, supported by expert technicians who understand the needs of local drivers in Toronto.

This case demonstrates how a simple routine service can uncover hidden issues and prevent major repairs—especially in high-kilometre work vehicles.

How does the Temperature affect Radiator Coolant?

Vehicle radiators and cooling systems play a vital role in ensuring your car runs smoothly, regardless of the season. One key factor affecting their performance is the fluctuation in temperature, which can have a significant impact on the coolant within the radiator. Coolant, also known as antifreeze, is designed to regulate your engine’s temperature by absorbing heat and transferring it away. However, its efficiency can diminish under colder weather conditions.

During colder months, lower temperatures can thicken the coolant if its mixture ratio isn’t optimal, reducing its ability to flow and protect the engine. Conversely, in the heat of summer, excessively high temperatures can cause the coolant to overheat, losing its capacity to keep the engine cool. Over time, exposure to such temperature extremes may lead to the coolant breaking down, becoming contaminated, or even evaporating, leaving the system vulnerable.

Maintaining the proper balance of coolant and ensuring it remains in good condition is crucial for preventing engine overheating or freezing. As such, regular inspection of the radiator and cooling system, particularly as seasons change, is essential to keep your vehicle functioning efficiently and to avoid costly repairs.

Radiators can fail for a variety of causes, many of which develop gradually and go unnoticed until significant damage has occurred. Understanding these potential issues can help car owners take proactive steps to avoid costly repairs. Below are some of the most common causes of radiator failure:

Corrosion  Over time, radiators are exposed to moisture, road salts, and other contaminants, which can lead to corrosion. Corroded areas can weaken the radiator and eventually cause leaks, reducing its ability to regulate engine temperature. Regularly flushing the coolant and using the correct type of antifreeze can help minimise corrosion.

Clogged Radiator  The accumulation of debris, rust, or dirt inside the radiator can obstruct the flow of coolant. Blockages can lead to inefficient cooling, resulting in overheating. Inspecting and flushing the cooling system periodically can prevent blockages and maintain smooth coolant circulation.

Coolant Leaks  Leaks are one of the most common reasons for radiator failure. These can occur due to worn or damaged hoses, faulty seals, or cracks in the radiator itself. Even a small leak can lead to a significant drop in coolant levels, causing overheating if left unaddressed.

Thermostat Malfunction  The thermostat regulates the flow of coolant between the engine and the radiator. If the thermostat becomes stuck—whether in the open or closed position—it can disrupt the cooling process. This can lead to overheating or overcooling, both of which put stress on the radiator and engine.

Pressure Build-Up  Radiators are designed to operate under specific pressure levels. However, a faulty radiator cap, which is responsible for maintaining the correct pressure, can lead to excessive pressure build-up. This can cause the radiator or hoses to crack and fail.

Physical Damage  External damage, such as dents or punctures caused by road debris, accidents, or poor handling during maintenance, can compromise the radiator’s structural integrity. Even small impacts can result in coolant leaks or diminished cooling performance.

Age and Wear  Like any other component, radiators have a finite lifespan. Over time, materials like metal and plastic weaken due to thermal expansion and contraction. Older radiators are more prone to leaks, corrosion, and cracking, making timely replacement essential.

By recognising these common causes of radiator failure, car owners can take preventive action and address small issues before they escalate. Regular maintenance, including checking coolant levels and inspecting the radiator for visible damage, can go a long way in extending the life of your vehicle’s cooling system.

To ensure the engine cooling system is functioning effectively, it’s important to inspect not only the radiator but also other key components within the system. Each part plays a vital role in keeping your vehicle’s engine at the correct operating temperature, and neglecting any of these can lead to costly issues down the road. Here are some of the critical areas that should be inspected during maintenance:

Coolant Hoses and Clamps  The hoses in your cooling system are responsible for transporting coolant between the radiator, engine, and other components. Over time, hoses can become brittle, crack, or develop bulges due to exposure to heat and pressure. Clamps that secure the hoses can also loosen or corrode, leading to leaks. Regularly inspecting hoses and clamps for wear, leaks, or damage is essential to avoid unexpected failures.

Water Pump  The water pump circulates coolant throughout the engine and radiator. If the pump fails or begins to leak, coolant flow can be disrupted, causing the engine to overheat. Checking the water pump for leaks, unusual noises, or signs of wear is an important part of any cooling system inspection.

Thermostat  The thermostat regulates the flow of coolant based on the engine’s temperature. A malfunctioning thermostat can stick in either the open or closed position, leading to overcooling or overheating. Inspecting the thermostat and replacing it when needed helps ensure the cooling system operates correctly.

Cooling Fan  The cooling fan is designed to pull air through the radiator to help dissipate heat, especially when the vehicle is stationary or moving at low speeds. A faulty fan motor, damaged blades, or issues with the fan’s electrical connections can reduce its efficiency, leading to overheating. The fan and its components should be checked for proper operation during maintenance.

Radiator Cap  The radiator cap is often overlooked but plays a crucial role in maintaining the correct pressure within the cooling system. If the cap is damaged or unable to hold pressure, it can cause coolant loss and affect the system’s efficiency. Inspecting the radiator cap for wear and ensuring it creates a proper seal is a quick but vital step.

Heater Core  The heater core is a small radiator located inside the cabin that helps provide heat to the vehicle’s interior. It is also connected to the cooling system and can develop leaks or become clogged over time. A compromised heater core not only affects cabin heating but can also impact overall coolant flow, so it’s worth inspecting during maintenance.

Coolant Condition  The coolant itself is the lifeblood of the cooling system, and its condition is critical. Over time, coolant can degrade, lose its anti-corrosion properties, or become contaminated with debris and rust. Testing the coolant to ensure it maintains the proper mixture and remains free of contaminants can help prevent damage to other components.

Expansion Tank  The expansion tank is where excess coolant is stored as the system heats up and coolant expands. Cracks, leaks, or a faulty pressure cap on the tank can lead to coolant loss and decreased system efficiency. Inspecting the expansion tank for damage is a simple yet important step.

By routinely inspecting these components as part of a thorough cooling system maintenance schedule, you can identify and address potential issues before they escalate. This not only helps maintain the health of your engine but also ensures the reliability of your vehicle on the road.

Regular vehicle servicing is essential for keeping your car running smoothly, and a Full Car Log Book Service includes a comprehensive inspection of the radiator and cooling system. These checks ensure that your vehicle’s engine remains at the right temperature and continues to perform efficiently.

As part of a Full Car Service, the radiator is carefully inspected for any signs of leaks, corrosion, or physical damage. Coolant levels and condition are also checked to confirm the correct mixture ratio and ensure it hasn’t degraded or become contaminated. Identifying and addressing these issues early can prevent more serious problems, such as overheating or engine damage.

In addition to the radiator itself, the service includes an assessment of the cooling system’s other vital components. Hoses are examined for cracks, bulges, or wear, while clamps are checked to ensure they are secure and free from corrosion. The radiator cap is tested to confirm it maintains the appropriate system pressure, and the water pump is inspected for leaks or unusual noises that may indicate wear.

This thorough inspection also covers the thermostat, cooling fan, heater core, and expansion tank, all of which contribute to the overall performance of the cooling system. By addressing wear or potential faults during a routine service, you can help avoid unexpected breakdowns and extend the life of your vehicle’s engine.

A properly maintained cooling system is key to preventing costly repairs and ensuring a reliable, stress-free driving experience. When your car is due for its next service, make sure the radiator and cooling system are checked as part of the process.

Plastic radiators and fittings are commonly found in modern vehicles due to their lightweight and cost-effective nature. However, it’s important to understand that plastic components have a limited lifespan (5 - 10 years) and can deteriorate over time. Factors such as constant exposure to extreme temperatures, pressure changes, and general wear and tear can cause the plastic to weaken, leading to cracks or leaks.

Car owners should regularly monitor their vehicles for signs of plastic radiator deterioration. One of the earliest indicators of an issue is the appearance of coolant drips underneath the car, particularly after it has been parked for a while. You may also notice a drop in coolant levels, which is another sign that something is amiss. Ignoring these early warnings can result in more significant problems, such as engine overheating or damage.

When leaks occur due to the deterioration of plastic radiators or fittings, the only reliable solution is to replace the affected parts. Repairs are often temporary and may not provide the long-term reliability needed for the cooling system to function properly. Replacing the radiator and any damaged fittings ensures that your vehicle’s cooling system remains efficient and effective.

To stay ahead of potential issues, it’s wise to include radiator inspections as part of your routine vehicle maintenance. A professional mechanic can identify early signs of wear or damage and advise on the best course of action. Keeping an eye on coolant levels and addressing any leaks promptly will help maintain your vehicle’s performance and prevent costly engine repairs down the line.
