Supply note: Use THH260727-003 for quotations, sample approval, packaging and order traceability.
DS7G-9K478-DB covers a multi-branch Ford thermostat housing that distributes coolant between the engine, radiator and related thermal circuits. Yongshang Auto records the part as THH260727-003 for B2B enquiry, sample review and shipment traceability.
The supplied application reference includes Ford Focus, Mondeo and Kuga source applications using the 1.5 EcoBoost cooling layout. Since the list spans several vehicles or platforms, the Model filter is intentionally blank and final fitment should rely on vehicle-specific evidence.

Multi-Circuit Routing for Ford EcoBoost Cooling
Several hose ports meet at this housing, allowing the thermostat chamber to coordinate flow through the main cooling route and auxiliary branches. Each outlet direction is designed around the installed hose package.
The part must resist pressure pulses and repeated thermal expansion while keeping the internal valve area correctly aligned. A housing with one misplaced branch can interfere with surrounding components even if the bolt pattern looks similar.
Ford Port Map and Connector Validation
Confirm DS7G-9K478-DB and any supersession through VIN, engine designation and build data. Photograph the removed unit before disconnecting hoses so every branch can be matched.
Compare the large outlets, small return ports, mounting lugs, electrical provision and gasket profile. Review DS7G-9K478-DA or other related numbers only through a verified cross-reference.
Pressure Boundary and Assembly Review
Examine the moulded body for seam splits, damaged hose spigots and distorted bolt bosses. Move the internal valve only as permitted by the product design and protect connector pins from moisture.
Use new seals and the Ford tightening sequence. Refill with specified coolant, purge air and inspect every branch under operating temperature before road testing.
Procurement, Packing and Sample Confirmation
Reference DS7G-9K478-DB as the OE identifier and THH260727-003 as the internal item code. Include required volume, destination, carton marking and label format in the quotation request.
Before batch supply, buyers may submit VIN data, engine information, measurements and photographs of the removed component. A physical sample can be used when catalogue evidence is incomplete.
