What to quote
State the thermostat quantity, vehicle application and agreed assembly contents. Identify pieces per set and any separately priced hardware before comparing quotations.
Hyundai Elantra · Engine, Fuel, Cooling, Electrical & A/C
Specify Elantra thermostat by engine and temperature specification. Retain bypass and seal arrangement and insert or housing supply so offers describe the same assembly.

| Record | Details to retain |
|---|---|
| Engine and temperature specification | Identify engine and temperature specification from the vehicle, installed assembly or readable label. |
| Bypass and seal arrangement | Show bypass and seal arrangement in photographs and retain measurements that distinguish the interfaces. |
| Insert or housing supply | Specify insert or housing supply together with every piece required in the quoted assembly. |
Opening specification, housing and bypass layout must match the engine, not only the outer diameter.
For this thermostat, keep XD/HD/MD/AD/CN7 generation, body style, production date, engine or Hybrid system, transmission and sales market on the same record. The Elantra generation and Avante market guide explains why a regional name alone is insufficient.
When this component is part of a mixed system order, use the powertrain & performance identification to separate neighboring assemblies.
Send overall and mounting or connection photographs. For the thermostat, retain bypass and seal arrangement and insert or housing supply; mark unknown values instead of borrowing a number from another generation. Use the OE and vehicle-identification checklist to organize the evidence.
Give every linked assembly its own specification; approving the thermostat does not confirm the surrounding parts.
Elantra Water Pump — Pump drive, impeller and housing must stay with the engine; a gasket outline is not sufficient identification. Confirm engine and coolant circuit and drive and impeller arrangement on its own order line.
Elantra Radiator — Engine, CVT cooler connections, core size and fan package vary by generation and trim. Confirm engine, transmission and cooling package and core dimensions and hose positions on its own order line.
Elantra Radiator Cooling Fan — Motor count, shroud, control module and connector must match the radiator/condenser stack. Confirm cooling layout and fan position and motor or mechanical drive on its own order line.
Elantra Alternator — Output, pulley and charging control can differ by engine and production market. Confirm engine and charging specification and output, connector and regulation on its own order line.
State the thermostat quantity, vehicle application and agreed assembly contents. Identify pieces per set and any separately priced hardware before comparing quotations.
Protect the valve and sealing rim.
Before approving the thermostat, agree sample and inspection requirements using the quality-control checklist. Return to the Elantra parts directory for other systems.
For thermostat requirements on other vehicles, compare the radiator and cooling directory. Keep the Elantra specification and every other approved model on separate order lines.
