Coolant Thermostat Housing Assembly for BMW 11518516206

Product Overview

Coolant Thermostat Housing Assembly for BMW 11518516206 is a direct-reference replacement for the coolant control circuit of BMW vehicles. It is listed here against OEM 11518516206, so the part can be matched to a vehicle without guesswork. 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 leaking sensor bosses and elements that stick part open 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

• 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 11518516206 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.
• 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.

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. Here the thermostat housing assembly is ordered against 11518516206 and travels with the rest of the BMW branch.

Counter stock for a busy platform

BMW volume in the region justifies holding the line on the shelf instead of ordering it in per job. This reference, 11518516206, is bought for exactly that situation on BMW vehicles.

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, 11518516206, is bought for exactly that situation on BMW vehicles.

Who It Is For

• Aftermarket distributors — stocking cooling-system lines for BMW across a regional network and needing a reference-accurate catalogue behind the shelf. What they need from 11518516206 is that it fits the BMW on the ramp today.
• Workshop and fast-fit chains — replacing thermostat housing assemblys on BMW daily and judging a supplier on whether the part fits first time. For them 11518516206 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 order 11518516206 by the carton and reorder against the same number.

Problems It Solves

Unclear compound

Confirm the compound against the reference before ordering, because visually identical parts are moulded in different materials. With 11518516206 the check is the opening temperature, the housing outline and whether the unit is map-controlled, and it happens before despatch.

Reference mismatch

Visually identical parts carry different connector geometry between model years. Quoting OEM 11518516206 fixes the identity before money moves. For this thermostat housing assembly the answer is the reference, 11518516206, on every document.

Split ordering

Sourcing one hose from one supplier and the matching flange from another doubles the freight and the paperwork for the same repair. With 11518516206 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 105°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 11518516206 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 BMW platform was designed around, and fit any seal or O-ring supplied with 11518516206 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.
