- Listed MOQs for these engine coolant thermostats start at 10 units per SKU. Factories often accept a smaller trial order for first-time buyers at a higher unit price.
- Will these engine coolant thermostats fit my 2019 Toyota Corolla?
- Every part on this page is matched to the 2019 Toyota Corolla by OEM fitment data. Before ordering, confirm your exact OEM number, trim and drivetrain on the part page — interchange can vary by trim, engine and build region.
- Which thermostat specifications must match the original part?
- Confirm the OE-specified opening temperature, full-lift temperature, valve diameter, bypass configuration and housing or flange dimensions; a visually similar thermostat can still cause slow warm-up or overheating. Ask for hot-water opening and lift curves, cold-seat leakage limits, thermal-cycle endurance data, corrosion-resistant materials, and the correct gasket or O-ring in every kit.
