Radiator Testing & Diagnosis Cape Town
Is your vehicle overheating or losing coolant? At Radiator King we provide comprehensive radiator testing and diagnosis services in Cape Town to accurately identify problems in your cooling system before they cause serious engine damage.
Bring your car or radiator to our Montague Gardens workshop for a full professional assessment. Our experienced technicians use proven diagnostic methods to find leaks, blockages, contamination and airflow issues quickly and accurately.
What We Check During Radiator Testing & Diagnosis
Visual Inspection
- Coolant leaks from the radiator, hoses, connections and water pump
- Oil contamination in the coolant reservoir or radiator (often a sign of a leaking oil cooler, head gasket or internal seal failure)
- Clogged or bent radiator fins that restrict airflow
- Physical damage, corrosion or debris build-up on the radiator core
Pressure Test
We pressurise the cooling system to the rated capacity of the radiator cap. The system must hold pressure for at least two minutes. A drop in pressure indicates leaks in the radiator, hoses, water pump, heater core or cylinder head gasket.
Block Test (Combustion Leak Test)
This specialised test detects exhaust gases in the cooling system — a clear indicator of a blown head gasket, cracked cylinder head or cracked engine block. Early detection can save you from major engine repairs.
Blockage & Flow Test
We measure temperature differences across the cooling system to identify restricted coolant flow caused by a blocked radiator, faulty thermostat or air pockets. Proper bleeding is performed where needed.
Airflow Test
We check that the radiator fan is operating correctly and that air can flow freely through the radiator. Bent, damaged or clogged fins (from bugs, leaves, dirt or gravel) significantly reduce cooling efficiency and are carefully inspected and corrected where possible.
Why Proper Radiator Diagnosis Matters
A failing cooling system can lead to overheating, warped cylinder heads, blown head gaskets and expensive engine damage. Accurate radiator testing and diagnosis allows us to pinpoint the exact problem so we can recommend the most cost-effective solution — whether it’s a simple repair, re-coring, cleaning or a full radiator replacement.
