Inputs → requests → comparison → confirmation for automotive thermostat factory specifications and quote ranges.

Define the coordination scope

Requirements review

Buyer supplies engine code, opening temperature with units, valve diameter, housing interface, seal package preference, quantity by configuration and US destination. Drawings can follow after the first reply.

Supplier questions

Ask factories about wax-pellet or map-controlled construction, housing alloy when an aluminum body is quoted, gasket materials, sample options and which application documents apply to the exact assembly offered.

Quote comparison

Separate unit cost, packing inserts versus housing assemblies, freight, taxes and service costs. Keep insert-only lines apart from thermostat-with-housing packages when ranking offers.

Order handoff

Record approved sample identity, unresolved temperature-unit or interface questions and each party’s delivery responsibility before first-batch production is discussed.
