Coolant Thermostat Housing Assembly for Mercedes-Benz A2742000715

Product Overview

A Thermostat Housing Assembly for Mercedes-Benz vehicles, held against OEM A2742000715 and SU00100713. In service the part carries the wax element, housing, seals and — on mapped units — the heater and temperature sensor that govern warm-up. The coolant control circuit gives this part a hard life: heat soak, vibration and pressure cycling. Typical end-of-life signs are elements that stick part open and seals that take a set after repeated heat cycles, which reach the workshop 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

• Tooling route for obsolete references — Where the reference is out of production, we develop the mould from the sample you supply rather than turning the enquiry away.
• Checked on the features that matter — Inspection concentrates on the opening temperature, the housing outline and whether the unit is map-controlled — the dimensions that put a part back in the box if they are wrong.
• 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.

Application Scenarios

Warranty-expired fleet maintenance

A fleet past dealer coverage moves to independent supply and needs the same reference coverage at a working price. With A2742000715 on the list the rest of the coolant control circuit can be priced at the same time.

Counter stock for a busy platform

Mercedes-Benz volume in the region justifies holding the line on the shelf instead of ordering it in per job. On this reference that means quoting A2742000715 with the quantity and letting the packing follow.

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. For A2742000715 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

• Workshop and fast-fit chains — replacing thermostat housing assemblys on Mercedes-Benz daily and judging a supplier on whether the part fits first time. For them A2742000715 is a line on a shelf, not a project.
• Online parts sellers — listing by OEM reference, where a mismatched number turns into a return and a negative rating. They judge A2742000715 on one thing: whether it matches the part that came off.
• Fleet and bus operators — running Mercedes-Benz vehicles past warranty and buying cooling-system parts by the box to keep downtime short. For them A2742000715 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. On A2742000715 that is settled before the quotation goes out.

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 A2742000715 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 this thermostat housing assembly the answer is the reference, A2742000715, 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 A2742000715 and SU00100713 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 A2742000715 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.
