How do I choose a compatible car radiator?

Match the vehicle's year, make, model, engine, transmission, radiator dimensions, hose positions, mounting points and OEM part number.

Can I replace only the thermostat?

Yes, if diagnosis confirms the thermostat is faulty and other cooling system components are functioning correctly.

Are aluminium radiators better than copper-brass radiators?

Neither is universally better. Performance depends on core design, airflow, coolant flow, construction and vehicle fitment.

Compare Car Radiators and Engine Cooling Components

Understand how radiators, fans, pumps, thermostats, hoses and coolant reservoirs work together, and compare replacement options before you buy.

Fitment first: Verify your vehicle's VIN, engine variant, OEM reference and manufacturer service information before purchasing. Cooling system components can vary within the same model year.

Explore cooling components

Radiators

Transfer heat from circulating coolant to passing air. Compare core size, rows, materials, inlet/outlet layout and transmission cooler connections.

Water pumps

Circulate coolant through the engine and heat exchanger. Compare drive type, impeller design, seals and fitment.

Thermostats

Regulate coolant flow as the engine warms. Match opening-temperature specification and housing configuration.

Cooling fans

Move air through the radiator at low vehicle speeds. Check electric versus mechanical drive, control system and shroud compatibility.

Hoses and reservoirs

Carry coolant and accommodate thermal expansion. Check hose routing, pressure ratings, cap specification and connector geometry.

Compare radiator construction

Type	Typical strengths	Considerations	Best use
Aluminium core with plastic tanks	Lightweight, widely available as OEM-style replacements	Tank seams and plastic aging can cause leaks	Daily driving with exact OE-equivalent fitment
All-aluminium	Robust welded construction in suitable designs	Build quality, corrosion protection and mounting are important	Selected performance or heavy-duty applications
Copper-brass	Repairable in some designs; established construction	Often heavier; efficiency varies with core geometry	Older vehicles and compatible specialty applications

Buying and inspection checklist

Confirm vehicle year, make, model, engine and transmission configuration.
Compare OEM part numbers, mounting brackets, ports, dimensions and electrical connectors.
Inspect packaging, welds, seams, hose necks and warranty terms.
Use the vehicle manufacturer's specified coolant type and mixing procedure.
After installation, follow the prescribed bleeding procedure and check for leaks and correct operating temperature.

Frequently asked questions

How do I choose a compatible radiator?

Match the VIN or exact vehicle configuration, OEM reference, physical dimensions, hose positions, mountings and any integrated transmission cooler.

Does overheating always mean the radiator is bad?

No. Low coolant, air trapped in the system, faulty fans, thermostats, water pumps, pressure caps or other engine faults may also cause overheating.

Is an all-aluminium radiator always better?

No. Cooling capacity depends on the full core and airflow design, not material alone. Choose a quality component engineered for your vehicle.

Can I drive with an overheating engine?

Continuing to drive can cause serious damage. Stop safely, switch off the engine and allow it to cool. Never open a hot pressurised cooling system.
