Avoid Costly Repairs: Radiator & Transmission

Radiator and transmission issues are two of the biggest causes of costly engine damage. Here’s what to look out for and what to do.

Radiator Leaks: What to Know

Radiators keep engines cool. A leak can lead to overheating, so watch for:

• High engine temperatures
  
• Low coolant levels
  
• Coolant pooling under the car

In an emergency: Wait for the engine to cool, add water and drive to a trusted workshop.

Common causes:

Corrosion, overfilling, cracked hoses or a faulty thermostat can all lead to leaks.

Workshop fix:

They’ll check for cracks, test pressure, apply sealant if it’s minor or remove and repair the radiator if needed.

Check Your Transmission Fluid

Transmission fluid keeps your gears running smoothly. Low or old fluid can cause gear slipping or grinding.

How to check it:

Run the engine, park on level ground and use the dipstick (if your car has one). Top up through the dipstick tube using a funnel.

If there’s no dipstick, your car may have a sealed system. A workshop can help.

When to replace:

Check regularly. Fluid can last up to 160,000 km but may need changing sooner depending on wear and driving conditions.
