Thermostat Assemblies

Thermostat Housings Listed by Opening Temperature

Thermostat assemblies and water flanges with the opening temperature on the listing, because a housing that fits but opens late still throws a fault.

What We Supply

Cooling System Parts Catalogued by Reference

Six product groups covering the wet side and the air side of the engine. Every listing carries the OEM numbers it replaces, because that is the only field a buyer can check before the part is fitted.

What We Solve

The Four Problems Behind Most Cooling System Enquiries

  1. The reference does not match the picture

    Model-year changes move connector geometry while the outline stays the same. Ordering against the OEM number instead of a photograph removes the argument.

  2. The line is split across three suppliers

    Hose here, flange there, thermostat somewhere else. One cooling-system range covering more than 4000 types puts the platform on one packing list.

  3. The reference has gone out of production

    The vehicle has not. Send the sample and we quote from it, including mould development where no tooling exists.

  4. The part arrives crushed or wrongly labelled

    Cartons are marked with the reference and packed for a sea leg, so a warehouse can check a delivery without cutting every box open.

Answers

Questions Buyers Ask Before the First Order

What does Hunan Woojin Autoparts actually supply

Engine cooling system parts for passenger cars and light commercials: air intake hoses, turbo and intercooler hoses, coolant and radiator hoses, thermostat housing assemblies and water flanges. The range covers German, French, Japanese, American and Korean vehicles and runs to more than 4000 types, of which 178 references are published on this site.

How do I order a part that is not on the website

Send the OEM reference, or the old part or a drawing. We quote from the sample and develop the mould where the tooling no longer exists, so an obsolete reference does not end the conversation.

Which markets do you already ship to

Europe, the Middle East and South America are the established markets for the range. Packing and carton marking are set up for sea freight rather than for domestic distribution.

Do you sell single pieces

The range is set up for distributors, workshop chains and exporters buying by the carton. Minimum quantities are confirmed per reference when you ask for a quotation.

How are parts matched to a vehicle

By OEM reference. Every product page lists the numbers the part replaces plus our internal reference, so a buyer can confirm identity before the order is placed rather than after the box is opened.

Can you put our own carton marking on the boxes

Carton marking and packing are agreed per order. Tell us how the part is picked at your end and the cartons are labelled to match.

What certifications are available

Certification documents are not published on this site. Ask by email for the documentation that applies to your market and the references you are buying.
