Coolant Pipe Hose for Tesla 1077594-00-B

Product Overview

Coolant Pipe Hose for Tesla 1077594-00-B covers the coolant circuit on Tesla applications. The reference set on file is OEM 1077594-00-B, which is the figure to quote when you send an enquiry. This part routes coolant between the block, the expansion tank, the heater circuit and auxiliary loops. The failure modes that bring it across a parts counter are brittle sections next to hot castings and swollen bores, reported as slow coolant loss, repeated top-ups between services and a sweet smell after shutdown. 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

• 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.
• Matched to how the part actually fails — Brittle sections next to hot castings and swollen bores are the reasons this reference is bought, so those are the features checked before packing.
• 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 1077594-00-B. You quote the number, we confirm against the same number, and the part that ships is the one on the invoice.

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. Here the coolant hose is ordered against 1077594-00-B and travels with the rest of the Tesla branch.

Rebuild of an obsolete platform

The original reference is no longer produced, so the part is made from a supplied sample. This reference, 1077594-00-B, is bought for exactly that situation on Tesla vehicles.

Mixed container for a distributor

A quarterly container is filled across families — intake, charge air, coolant and thermostat lines — to a single packing list. Here the coolant hose is ordered against 1077594-00-B and travels with the rest of the Tesla branch.

Who It Is For

• Fleet and bus operators — running Tesla vehicles past warranty and buying cooling-system parts by the box to keep downtime short. For them 1077594-00-B is a line on a shelf, not a project.
• Radiator and cooling specialists — rebuilding cooling systems and sourcing the hoses, flanges and housings for a platform in one go. They order 1077594-00-B by the carton and reorder against the same number.
• Exporters and consolidators — shipping mixed cooling-system pallets into Europe, the Middle East and South America. What they need from 1077594-00-B is that it fits the Tesla on the ramp today.

Problems It Solves

Unclear compound

Confirm the compound against the reference before ordering, because visually identical parts are moulded in different materials. On 1077594-00-B that is settled before the quotation goes out.

Reference mismatch

Visually identical parts carry different connector geometry between model years. Quoting OEM 1077594-00-B fixes the identity before money moves. That is why 1077594-00-B carries its full cross-reference set on this page.

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 1077594-00-B the check is the connector type at each end, the routing bends and whether a sensor port is moulded in, and it happens before despatch.

Technical Features

The part serves the coolant circuit and routes coolant between the block, the expansion tank, the heater circuit and auxiliary loops. Material for this reference is confirmed per enquiry.

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 1077594-00-B against the number on the part you removed. Do not match on outline alone.

2. Check the interfaces

   Compare the connector type at each end, the routing bends and whether a sensor port is moulded in 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 Tesla platform was designed around, and fit any seal or O-ring supplied with 1077594-00-B rather than carrying the old one over.

5. Pressure check before handover

   Refill, bleed the circuit and check for weeping at quick-connect collars at working temperature before the vehicle leaves.
