Engine Block + Head Gasket

An engine block, or cylinder block, acts as a structural framework for all the essential components required for combustion including pistons, cylinder heads, camshafts, valves, crankshafts, oil galleries and coolant passages. As the engine block is a core component for any vehicle, it is designed for durability to tolerate high-temperature & pressure. If the engine block is damaged, you will most likely have to replace it since repairing can be a tough feat.

Cylinder Head

The cylinder head is a three-piece assembly, part of the combustion chamber, and consisting of a lower member that contains the gas passages, a mounting for the injector valves and the ignition plug. The cylinder head itself is a piston-like member retained by a flange and eight screws to the lower member of the chamber. The cylinder head mounts on the cylinder block (engine housing) and needs to be continuously cooled.

Thermostat

The thermostat is responsible for regulating coolant flow through the engine. If the engine is cold, the thermostat stays closed to let the engine warm up. As the engine heats up, the thermostat gradually opens, allowing coolant to reach the radiator to bring the engine to its optimal temperature. If the thermostats begins to fail, the engine could overheat or overcool, and it could lead to costly repairs.

Water Pump

The “water” pump is responsible for pushing coolant through the engine to help regulate its temperature. It helps ensure the motor remains at a constant temperature, no matter the weather or the strain put on it.

Hoses & Reservoirs

The vehicle’s hoses are made of flexible rubber composites that handle vibrations from the engine. Hoses are designed to withstand coolant under intense pressure, extreme temperatures, oils, dirt, and sludge.
 
The coolant reservoirs are a storage tank for excess engine coolant and allow engine coolant to flow in and out per the needs of the cooling systems. As the engine coolant temperature rises, the coolant expands, and the radiator cap as well as the plastic reservoir walls allow excess pressure to bleed off.

Cooling Plates

EV battery cooling plates regulate the temperature of the battery pack and some of the electronics by circulating coolant between two thin aluminum (Al) sheets. Battery fluid goes through tubes, cold plates, or other components that surround the battery cells and carry heat to another location, such as a radiator or a heat exchanger. Battery plates carrying the liquid prevent direct electrical contact between the cells and the liquid coolant.

Damage to an EV coolant system often results in costly battery system replacement.

HVCH

High Voltage Coolant Heaters have been developed to keep the core components of hybrid and pure electric vehicles at an optimal temperature, improving charging efficiency, durability and driving range. This heating system delivers heat to the vehicle interior and helps clears the ice from windows quickly.

Condenser

The condenser’s role is essentially that of a heat exchanger, passing refrigerant through a large block where it transfers the thermal properties of the cryogen to other parts of the cooling system. The condenser is where the hot liquid refrigerant transfers its heat to the coolant, which then carries it to the radiator.

Inverter

An inverter is an electrical device that converts sourced electricity from DC (Direct Current) to AC (Alternating Current). DC power is fed to the primary winding in a transformer within the inverter housing. Through an electronic switch, the current’s direction flow is continuously and periodically reversed. The in/outflow of electricity produces AC current in the transformer’s secondary winding circuit. Ultimately, this induced alternating current electricity provides power for an AC load—for example, an electric vehicle’s (EV) traction motor.
