Coolant Water Flange Pipe for BMW OEM 11531247122

Product Overview

Coolant Water Flange Pipe for BMW OEM 11531247122 is a direct-reference replacement for the coolant distribution point of BMW vehicles. It is listed here against OEM 11531247122, so the part can be matched to a vehicle without guesswork. The coolant distribution point gives this part a hard life: heat soak, vibration and pressure cycling. Typical end-of-life signs are leaking O-ring grooves and hairline cracks in the moulding, which reach the workshop as a coolant drip at the head, low coolant warnings and an intermittent temperature signal. 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

• Checked on the features that matter — Inspection concentrates on the port count, the bolt pattern and whether the sensor and seals are included — the dimensions that put a part back in the box if they are wrong.
• Built for the duty of the coolant distribution point — The part joins several coolant lines at the cylinder head and usually carries the temperature sensor and its seals, 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 11531247122. You quote the number, we confirm against the same number, and the part that ships is the one on the invoice.

Application Scenarios

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. On this reference that means quoting 11531247122 with the quantity and letting the packing follow.

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 water flange is ordered against 11531247122 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. On this reference that means quoting 11531247122 with the quantity and letting the packing follow.

Who It Is For

• Radiator and cooling specialists — rebuilding cooling systems and sourcing the hoses, flanges and housings for a platform in one go. What they need from 11531247122 is that it fits the BMW on the ramp today.
• Exporters and consolidators — shipping mixed cooling-system pallets into Europe, the Middle East and South America. What they need from 11531247122 is that it fits the BMW on the ramp today.
• 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 11531247122 is that it fits the BMW on the ramp today.

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 11531247122 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. On 11531247122 that is settled before the quotation goes out.

Returns from wrong fitment

Every returned part costs the freight twice. Checking the port count, the bolt pattern and whether the sensor and seals are included before despatch is cheaper than a credit note. For this water flange the answer is the reference, 11531247122, on every document.

Technical Features

The part serves the coolant distribution point and joins several coolant lines at the cylinder head and usually carries the temperature sensor and its seals. It is moulded in PA66 glass-filled nylon, chosen because glass-filled PA66 gives a rigid pipe that holds its shape against vibration and keeps clamp faces dimensionally stable at under-bonnet temperature.

Used where the part must hold a fixed geometry and carry bolted or clipped interfaces. PA66 mouldings crack rather than weep, so a hairline split can empty a coolant system quickly once it opens.

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 11531247122 against the number on the part you removed. Do not match on outline alone.

2. Check the interfaces

   Compare the port count, the bolt pattern and whether the sensor and seals are included before the vehicle is stripped further.

3. Inspect on arrival

   Look for transit damage on sealing faces and connectors. PA66 mouldings crack rather than weep, so a hairline split can empty a coolant system quickly once it opens.

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 11531247122 rather than carrying the old one over.

5. Pressure check before handover

   Refill, bleed the circuit and check for hairline cracks in the moulding at working temperature before the vehicle leaves.
