Cooling System parts and their functions

9 top-level parts · 90 parts in total · full bill of materials below

#	Part	Qty	What it does
1	Radiator	1×	Finned aluminium heat exchanger that passes hot coolant through thin tubes so air flowing across the fins carries the heat away.
2	Coolant Pump	1×	Electric or belt-driven centrifugal pump that circulates coolant through the engine, motor, battery, or heat exchanger.
3	Coolant Hose	4×	Reinforced rubber or silicone hose that carries coolant between the engine, pump, radiator, and heater.
4	Coolant	1×	Water and glycol mixture with corrosion inhibitors that carries heat through the cooling circuit without freezing or boiling.
5	Blower Motor	1×	fan drive
6	Coolant Hose & Clamp	18×	Silicone coolant hose section with its clamps.
7	Saloon Convector Heater	8×	saloon convectors
8	Heater Pipe & Hose	16×	Coolant pipes and hoses running the length of the saloon to the convectors.
9	Body Bolt	40×	Flanged hex bolt used throughout the body, floor and equipment mounts.
