Coolant Thermostat Housing for Mercedes-Benz A2742000615

Product Overview

This Thermostat Housing Assembly is supplied for Mercedes-Benz applications and is catalogued against OEM A2742000615. Matching starts from the reference rather than from a picture, which is what keeps a container of parts out of the returns pile. This part carries the wax element, housing, seals and — on mapped units — the heater and temperature sensor that govern warm-up. The failure modes that bring it across a parts counter are leaking sensor bosses and elements that stick part open, reported as a gauge that never settles in the normal band, higher fuel consumption and thermostat fault codes. It sits inside a cooling-system programme of more than 4000 types, so the same order can carry the neighbouring hoses, flanges and thermostat housings for the platform.

Key Benefits

• Consolidate the platform in one order — Hoses, flanges and thermostat housings for the same platform ship on one pallet, which shortens the paperwork and the freight bill.
• Sample-based production for parts not yet listed — Send the old part or a drawing and we quote from the sample, including mould development where no tool exists.
• Inspection before despatch — Parts are inspected before they leave, which for this family means checking the sealing faces and the connector geometry that decide whether it fits.
• 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.

Application Scenarios

Mixed container for a distributor

A quarterly container is filled across families — intake, charge air, coolant and thermostat lines — to a single packing list. On this reference that means quoting A2742000615 with the quantity and letting the packing follow.

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. Here the thermostat housing assembly is ordered against A2742000615 and travels with the rest of the Mercedes-Benz branch.

Warranty-expired fleet maintenance

A fleet past dealer coverage moves to independent supply and needs the same reference coverage at a working price. This reference, A2742000615, is bought for exactly that situation on Mercedes-Benz vehicles.

Who It Is For

• Fleet and bus operators — running Mercedes-Benz vehicles past warranty and buying cooling-system parts by the box to keep downtime short. What they need from A2742000615 is that it fits the Mercedes-Benz on the ramp today.
• Radiator and cooling specialists — rebuilding cooling systems and sourcing the hoses, flanges and housings for a platform in one go. They order A2742000615 by the carton and reorder against the same number.
• Exporters and consolidators — shipping mixed cooling-system pallets into Europe, the Middle East and South America. A2742000615 earns its shelf space through repeat demand on Mercedes-Benz platforms.

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. On A2742000615 that is settled before the quotation goes out.

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, A2742000615, 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. For this thermostat housing assembly the answer is the reference, A2742000615, on every document.

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 A2742000615 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 A2742000615 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.
