Coolant Thermostat Housing for Mercedes-Benz A2742000015

Product Overview

Coolant Thermostat Housing for Mercedes-Benz A2742000015 covers the coolant control circuit on Mercedes-Benz applications. The reference set on file is OEM A2742000015, which is the figure to quote when you send an enquiry. Because the part carries the wax element, housing, seals and — on mapped units — the heater and temperature sensor that govern warm-up, a worn one rarely fails cleanly — expect seals that take a set after repeated heat cycles and cracked plastic housings long before it separates, with a gauge that never settles in the normal band, higher fuel consumption and thermostat fault codes as the first complaint over the counter. We hold it as part of a cooling-system range of more than 4000 types built for the independent aftermarket in Europe, the Middle East and South America.

Key Benefits

• Built for the duty of the coolant control circuit — The part carries the wax element, housing, seals and — on mapped units — the heater and temperature sensor that govern warm-up, so the compound and the wall construction are matched to that circuit rather than to a generic hose spec.
• Export packing as standard — The range ships to Europe, the Middle East and South America, so cartons are packed for long sea legs rather than for a local van run.
• One reference set on every document — OEM A2742000015 appears on the quotation, the packing list and the carton label, so a warehouse can check a delivery without opening the box.
• Mixed pallets instead of single lines — A cooling-system range of more than 4000 types means a slow-moving line can travel with fast movers instead of being ordered on its own.

Application Scenarios

Breakdown repair

The vehicle is off the road and the part has to be right the first time, which makes the reference match the whole decision. On this reference that means quoting A2742000015 with the quantity and letting the packing follow.

Rebuild of an obsolete platform

The original reference is no longer produced, so the part is made from a supplied sample. With A2742000015 on the list the rest of the coolant control circuit can be priced at the same time.

Mixed container for a distributor

A quarterly container is filled across families — intake, charge air, coolant and thermostat lines — to a single packing list. For A2742000015 the practical step is confirming the opening temperature, the housing outline and whether the unit is map-controlled before the order is placed.

Who It Is For

• Exporters and consolidators — shipping mixed cooling-system pallets into Europe, the Middle East and South America. They judge A2742000015 on one thing: whether it matches the part that came off.
• Aftermarket distributors — stocking cooling-system lines for Mercedes-Benz across a regional network and needing a reference-accurate catalogue behind the shelf. They judge A2742000015 on one thing: whether it matches the part that came off.
• Workshop and fast-fit chains — replacing thermostat housing assemblys on Mercedes-Benz daily and judging a supplier on whether the part fits first time. They order A2742000015 by the carton and reorder against the same number.

Problems It Solves

Split ordering

Sourcing one hose from one supplier and the matching flange from another doubles the freight and the paperwork for the same repair. For Mercedes-Benz buyers it is the difference between a stocked line and a credit note on A2742000015.

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. For this thermostat housing assembly the answer is the reference, A2742000015, on every document.

Returns from wrong fitment

Every returned part costs the freight twice. Checking the opening temperature, the housing outline and whether the unit is map-controlled before despatch is cheaper than a credit note. On A2742000015 that is settled before the quotation goes out.

Technical Features

The part serves the coolant control circuit and carries the wax element, housing, seals and — on mapped units — the heater and temperature sensor that govern warm-up. Material for this reference is confirmed per enquiry. The listed opening temperature is 97°C, which is the figure that has to match the vehicle.

Matched to the circuit the part serves. Confirm the compound against the reference before ordering, because visually identical parts are moulded in different materials.

Specifications

Values marked TBC are not stated on the source catalogue. They are confirmed in writing on the quotation rather than estimated here.

Comparison With the Alternatives

Use Guide

1. Confirm the reference

   Match OEM A2742000015 against the number on the part you removed. Do not match on outline alone.

2. Check the interfaces

   Compare the opening temperature, the housing outline and whether the unit is map-controlled before the vehicle is stripped further.

3. Inspect on arrival

   Look for transit damage on sealing faces and connectors. Confirm the compound against the reference before ordering, because visually identical parts are moulded in different materials.

4. Fit with the original clamp style

   Reuse the clamp type the Mercedes-Benz platform was designed around, and fit any seal or O-ring supplied with A2742000015 rather than carrying the old one over.

5. Pressure check before handover

   Refill, bleed the circuit and check for cracked plastic housings at working temperature before the vehicle leaves.
