Water Pumps
Start with the complete engine code and decide whether the request covers the pump, housing, pulley and gasket as separate or combined lines.
16100-39466 · Open guideCooling System
Thermostats
Record the engine, opening specification and whether the thermostat is separate from or integrated into the coolant inlet housing.

Selection matrix
What must be confirmed before quotation
| Decision point | Buyer evidence | Risk controlled |
|---|---|---|
| Cooling circuit | Engine, heater, oil-cooler or applicable hybrid circuit | Prevents unrelated circuits being combined |
| Heat exchanger | Core dimensions, thickness, ports, mounts and transmission cooler | Controls radiator configuration |
| Pump/thermostat | Mechanical or electric design, housing and opening temperature | Controls circulation specification |
| Fan system | Motor count, shroud, connector, controller and rotation | Controls fan assembly selection |
| Vehicle version | Engine, transmission, hybrid context, chassis and market | Separates regional cooling layouts |
System-specific risk
Radiators and cooling circuits can differ within one model year
Engine, transmission, climate package and hybrid configuration can change core size, ports, fan controls and pumps. Do not confuse an engine radiator with an A/C condenser or a separate hybrid cooling circuit.
Buyer FAQ
Corolla cooling system questions
Can a radiator be selected from model year alone?
No. Confirm core dimensions, port positions, transmission cooler, mounts, engine, transmission and chassis.
Can water pumps and thermostats ship in one order?
Yes. Keep each engine and component reference on a separate line with quantity and housing details.
Are fan motors supplied separately from the shroud?
It depends on the design and requested scope. State whether the inquiry is for a motor, blade, shroud or complete assembly.
How should hybrid cooling parts be requested?
Identify the exact circuit and complete hybrid vehicle information; do not assume engine and inverter cooling parts are shared.
