Cooling & HVAC
The cooling system maintains the engine at its optimal operating temperature (85-95°C). It circulates coolant through the engine block, cylinder head, and radiator.
Components
The cooling & hvac consists of: radiator, water pump, thermostat, coolant hoses, expansion tank, coolant temperature sensor, cooling fan, heater matrix, cabin air filter, AC compressor, AC condenser.
Petrol & diesel vehicles
Cooling systems are fundamentally the same across petrol and diesel engines. Diesel engines typically run at slightly lower temperatures.
Hybrid & electric vehicles
Electric vehicles still have a cooling system — for the battery pack and electric motor. Battery thermal management is critical for EV longevity. Some EVs use heat pumps for cabin heating instead of a heater matrix.
Common faults
The most common cooling & hvac faults we see across Bradford and West Yorkshire include: engine overheating, coolant loss, heater not blowing hot air, AC not cold, coolant temperature warning light, visible coolant leak, sweet smell from engine bay.
