Coolant Pipe Hose for Tesla Model 3 1077577-00-B

Product Overview

Ordered against OEM 1077577-00-B, this Coolant Hose replaces the original part in the coolant circuit on Tesla vehicles. The routes coolant between the block, the expansion tank, the heater circuit and auxiliary loops, so form and fit are not negotiable. Because the part routes coolant between the block, the expansion tank, the heater circuit and auxiliary loops, a worn one rarely fails cleanly — expect weeping at quick-connect collars and perished O-ring seats on moulded connectors long before it separates, with slow coolant loss, repeated top-ups between services and a sweet smell after shutdown as the first complaint over the counter. Hunan Woojin Autoparts supplies it from a cooling-system range of more than 4000 types covering German, French, Japanese, American and Korean vehicles.

Key Benefits

• One reference set on every document — OEM 1077577-00-B 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.
• Sample-based production for parts not yet listed — Send the old part or a drawing and we quote from the sample, including mould development where no tool exists.
• 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.

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. With 1077577-00-B on the list the rest of the coolant circuit can be priced at the same time.

Counter stock for a busy platform

Tesla volume in the region justifies holding the line on the shelf instead of ordering it in per job. This reference, 1077577-00-B, is bought for exactly that situation on Tesla 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. On this reference that means quoting 1077577-00-B with the quantity and letting the packing follow.

Who It Is For

• Exporters and consolidators — shipping mixed cooling-system pallets into Europe, the Middle East and South America. 1077577-00-B earns its shelf space through repeat demand on Tesla platforms.
• Aftermarket distributors — stocking cooling-system lines for Tesla across a regional network and needing a reference-accurate catalogue behind the shelf. They order 1077577-00-B by the carton and reorder against the same number.
• Workshop and fast-fit chains — replacing coolant hoses on Tesla daily and judging a supplier on whether the part fits first time. For them 1077577-00-B is a line on a shelf, not a project.

Problems It Solves

Unclear compound

Confirm the compound against the reference before ordering, because visually identical parts are moulded in different materials. That is why 1077577-00-B carries its full cross-reference set on this page.

Reference mismatch

Visually identical parts carry different connector geometry between model years. Quoting OEM 1077577-00-B fixes the identity before money moves. With 1077577-00-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.

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 1077577-00-B carries its full cross-reference set on this page.

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 1077577-00-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 1077577-00-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.
