19301‑R40‑A01 Engine Coolant Thermostat Assembly，Integrated Thermostat With Housing

This integrated thermostat assembly 19301‑R40‑A02 is an all‑in‑one temperature‑control component for engine cooling system. It combines wax‑type thermostat core and plastic housing into one complete unit, opens and closes precisely according to coolant temperature to adjust coolant circulation volume for Honda Accord CP2, CR‑V RE4, Crosstour TF1 and Acura TSX CU2 equipped with K24A / K24Z 2.4L engine from 2008‑2014. Constructed with high‑temperature‑resistant reinforced engineering‑plastic housing, precision wax‑thermostat core and matched sealing gasket. It delivers stable temperature‑switching performance, anti‑deformation and anti‑leakage capacity under long‑term high‑temperature cooling‑system working environment. All bolt‑hole layout, pipe‑port dimension and mounting‑surface structure strictly comply with OEM specifications. Every unit passes thermal‑switch test and pressure‑leakage inspection before shipment for direct bolt‑on installation without extra modification. Common failure symptoms include slow engine warm‑up, engine over‑heating, coolant leaking from thermostat joint, abnormal engine operating temperature. It is widely replaced during cooling‑system overhaul, serving as essential repair spare‑part for Honda K24 series gasoline‑engine maintenance.
