Coolant Water Flange Pipe for BMW OEM 11127806196

Product Overview

This Water Flange is supplied for BMW applications and is catalogued against OEM 11127806196 and 11122247744. Matching starts from the reference rather than from a picture, which is what keeps a container of parts out of the returns pile. Because the part joins several coolant lines at the cylinder head and usually carries the temperature sensor and its seals, a worn one rarely fails cleanly — expect stripped sensor threads and leaking O-ring grooves long before it separates, with a coolant drip at the head, low coolant warnings and an intermittent temperature signal as the first complaint over the counter. The part belongs to a cooling-system catalogue of more than 4000 types, which is the practical reason buyers consolidate a mixed pallet with us rather than splitting it across suppliers.

Key Benefits

• 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.
• Inspection before despatch — Parts are inspected before they leave, which for this family means checking the sealing faces and the connector geometry that decide whether it fits.
• 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.

Application Scenarios

Mixed container for a distributor

A quarterly container is filled across families — intake, charge air, coolant and thermostat lines — to a single packing list. With 11127806196 on the list the rest of the coolant distribution point can be priced at the same time.

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. For 11127806196 the practical step is confirming the port count, the bolt pattern and whether the sensor and seals are included before the order is placed.

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 11127806196 and travels with the rest of the BMW branch.

Who It Is For

• Workshop and fast-fit chains — replacing water flanges on BMW daily and judging a supplier on whether the part fits first time. What they need from 11127806196 is that it fits the BMW on the ramp today.
• Online parts sellers — listing by OEM reference, where a mismatched number turns into a return and a negative rating. For them 11127806196 is a line on a shelf, not a project.
• Fleet and bus operators — running BMW vehicles past warranty and buying cooling-system parts by the box to keep downtime short. What they need from 11127806196 is that it fits the BMW on the ramp today.

Problems It Solves

Unclear compound

PA66 mouldings crack rather than weep, so a hairline split can empty a coolant system quickly once it opens. With 11127806196 the check is the port count, the bolt pattern and whether the sensor and seals are included, and it happens before despatch.

Reference mismatch

Visually identical parts carry different connector geometry between model years. Quoting OEM 11127806196 and 11122247744 fixes the identity before money moves. For this water flange the answer is the reference, 11127806196, 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. That is why 11127806196 carries its full cross-reference set on this page.

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.

Comparison With the Alternatives

Use Guide

1. Confirm the reference

   Match OEM 11127806196 and 11122247744 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 11127806196 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.
