Thermostat Assemblies
This section lists 70 thermostat assemblies references for German, French, Japanese, American and Korean vehicles. Matching runs from the OEM reference, which is the only way to keep a mixed order accurate.
Buyers come to this group because a gauge that never settles in the normal band, higher fuel consumption and thermostat fault codes has already reached the workshop and the vehicle is waiting.

Who This Group Is For
Radiator and cooling specialists
rebuilding cooling systems and sourcing the hoses, flanges and housings for a platform in one go.
Exporters and consolidators
shipping mixed cooling-system pallets into Europe, the Middle East and South America.
Aftermarket distributors
stocking cooling-system lines for these platforms across a regional network and needing a reference-accurate catalogue behind the shelf.
What Goes Wrong Without the Right Reference
Reference mismatch
Visually identical parts carry different connector geometry between model years. Quoting the OEM number fixes the identity before money moves.
Split ordering
Sourcing one hose from one supplier and the matching flange from another doubles the freight and the paperwork for the same repair.
Parts that are no longer produced
When the original reference is dropped, the repair still exists. Sample-based production and mould development keep the line alive.
What the Parts Are Made From
| Material | Why it is used here | References |
|---|---|---|
| PA66 glass-filled nylon | Glass-filled PA66 gives a rigid pipe that holds its shape against vibration and keeps clamp faces dimensionally stable at under-bonnet temperature. | 11 |
Where These Parts Are Fitted
Rebuild of an obsolete platform
The original reference is no longer produced, so the part is made from a supplied sample.
Mixed container for a distributor
A quarterly container is filled across families — intake, charge air, coolant and thermostat lines — to a single packing list.
Scheduled cooling-system overhaul
The vehicle is in for a coolant leak and the workshop replaces the whole branch at once rather than chasing the next failure in a month.
Neighbouring Groups on the Same Platform
Cooling repairs rarely stop at one part. These groups travel on the same order.
Thermostat Assemblies — Buyer Questions
How many thermostat assemblies references are published
70 references are published in this group. They cover Audi, BMW, European and Asian vehicles, Ford, Jaguar Land Rover, Mercedes-Benz, Opel, Renault, Suzuki, Toyota and Volvo and are listed against the OEM numbers they replace. The wider cooling-system range runs to more than 4000 types.
Which materials are used across this group
PA66 (11 references). Material is listed per reference rather than per group, because two parts with the same outline are often moulded in different compounds.
Which opening temperatures are available in this group
Published units in this group cover 82°C, 83°C, 85°C, 87°C, 88°C, 89°C, 90°C, 92°C, 95°C, 97/105°C, 97°C, 103°C, 105°C and 108°C. Opening temperature is not interchangeable, so confirm the figure for the vehicle before ordering.
What should I check before ordering from this group
Check the opening temperature, the housing outline and whether the unit is map-controlled. Those are the features that decide fitment on this family, and they are what separates two references that look the same in a photograph.
How quickly can this group be quoted
Email the reference numbers and quantities to [email protected]. A written quotation comes back with packing details and carton counts so you can plan the container load.
Can parts from this group ship with other families
Yes. Mixing intake, charge air, coolant and thermostat lines on one pallet is the normal way this range is bought, and it keeps the freight cost per line down.
What if my reference is not published here
Send it anyway. Publication on this site is a subset of the range, and where a reference is out of production we quote from a supplied sample including mould development.
