Coolant Thermostat Housing for Mercedes-Benz A2642001501

Product Overview

A Thermostat Housing Assembly for Mercedes-Benz vehicles, held against OEM A2642001501 and A2642006600. 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. 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.
• Ordered by reference not by photo — The listing carries OEM A2642001501 and A2642006600. You quote the number, we confirm against the same number, and the part that ships is the one on the invoice.
• 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.

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, A2642001501, 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. Here the thermostat housing assembly is ordered against A2642001501 and travels with the rest of the Mercedes-Benz branch.

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 A2642001501 with the quantity and letting the packing follow.

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. A2642001501 earns its shelf space through repeat demand on Mercedes-Benz platforms.
• Radiator and cooling specialists — rebuilding cooling systems and sourcing the hoses, flanges and housings for a platform in one go. What they need from A2642001501 is that it fits the Mercedes-Benz on the ramp today.
• Exporters and consolidators — shipping mixed cooling-system pallets into Europe, the Middle East and South America. They judge A2642001501 on one thing: whether it matches the part that came off.

Problems It Solves

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. That is why A2642001501 carries its full cross-reference set on this page.

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. That is why A2642001501 carries its full cross-reference set on this page.

Unclear compound

Confirm the compound against the reference before ordering, because visually identical parts are moulded in different materials. With A2642001501 the check is the opening temperature, the housing outline and whether the unit is map-controlled, and it happens before despatch.

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.

Comparison With the Alternatives

Use Guide

1. Confirm the reference

   Match OEM A2642001501 and A2642006600 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 A2642001501 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.
