Coolant Thermostat Housing for Mercedes-Benz 2712000115

Product Overview

This Thermostat Housing Assembly is supplied for Mercedes-Benz applications and is catalogued against OEM 2712000115, 2712000215 and 2712000315. Matching starts from the reference rather than from a picture, which is what keeps a container of parts out of the returns pile. In service the part carries the wax element, housing, seals and — on mapped units — the heater and temperature sensor that govern warm-up. When it fails it usually shows seals that take a set after repeated heat cycles and cracked plastic housings, and the driver sees 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

• 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.
• Ordered by reference not by photo — The listing carries OEM 2712000115, 2712000215 and 2712000315. You quote the number, we confirm against the same number, and the part that ships is the one on the invoice.
• 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. This reference, 2712000115, is bought for exactly that situation on Mercedes-Benz vehicles.

Rebuild of an obsolete platform

The original reference is no longer produced, so the part is made from a supplied sample. For 2712000115 the practical step is confirming the opening temperature, the housing outline and whether the unit is map-controlled before the order is placed.

Mixed container for a distributor

A quarterly container is filled across families — intake, charge air, coolant and thermostat lines — to a single packing list. Here the thermostat housing assembly is ordered against 2712000115 and travels with the rest of the Mercedes-Benz branch.

Who It Is For

• Aftermarket distributors — stocking cooling-system lines for Mercedes-Benz across a regional network and needing a reference-accurate catalogue behind the shelf. For them 2712000115 is a line on a shelf, not a project.
• 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 2712000115 by the carton and reorder against the same number.
• Online parts sellers — listing by OEM reference, where a mismatched number turns into a return and a negative rating. For them 2712000115 is a line on a shelf, not a project.

Problems It Solves

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. With 2712000115 the check is the opening temperature, the housing outline and whether the unit is map-controlled, and it happens before despatch.

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 2712000115 that is settled before the quotation goes out.

Long lead times on slow movers

A slow line ordered alone waits for a container. Consolidated with fast movers it travels on the same shipment. For Mercedes-Benz buyers it is the difference between a stocked line and a credit note on 2712000115.

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 83°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.

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 2712000115, 2712000215 and 2712000315 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 2712000115 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.
