Product description

Thermostat Gasket No. 1632631050 is an original Toyota part responsible for sealing the connection between the thermostat and the water tank, to ensure that coolant does not leak and that the system pressure is maintained correctly.


Any defect in this face may lead to radiator water leakage or air entering the cooling system, causing the engine to overheat.


🚗 Compatible with:

  • Toyota FJ Cruiser 4.0
  • Toyota Prado 4.0

(1GR-FE engine – make sure the part number matches the chassis number VIN)


⚙️ What happens when the thermostat face is damaged?

  • Water leak under the thermostat housing
  • Low coolant level
  • Engine overheating
  • Air intake for the cooling system
  • Poor cooling efficiency


The cooling system relies on complete airtightness — any slight leak directly affects the operating temperature.


⭐ Why choose the original piece?

✔️ Perfect match to factory size

✔️ Heat and pressure resistant

✔️ Prevents leakage for a long time

✔️ Maintains the performance of the cooling system

✔️ Reduces the likelihood of disassembly and maintenance


🛠️ When should it be changed?

  • When changing the thermostat
  • When dismantling the water house
  • When there is a leak in the thermostat area
  • When maintaining the cooling system


It is always recommended to replace the faceplate when unscrewing the heat seal, even if it is in good condition.
