    No “OPENING TEMPERATURE” stamped on it.


    in 2 months

    I returned it and bought a genuine Toyota replacement Thermostat from Toyota which appeared to be of much better quality. Also, this replacement brand lacked an “opening temperature” stamped onto it and looked pretty cheaply made when sitting next to the Toyota brand which i was replacing. That thermostat never failed and the only reason i was replacing it was because i had to replace the Toyota factory original cheap plastic ‘Water Return/Thermostat Housing’ which developed stress cracks where the radiator water return hose attaches and which is EXTREMELY difficult to replace because of where Toyota engineers put it on the engine. After what I went through to replace the stress-cracked PLASTIC Water Return/Thermostat housing i did not want to have to do THAT again if the original thermostat eventually malfunctioned.

    2006 Toyota Sienna Thermostat Replacement


    in a year

    My 06 Sienna was running hot , the temperature gauge was moving erratically and my cooling fans were constantly on. After checking the coolant levels and fan clutch relay I decided to attempt to replace the thermostat myself. The job took about 2 hours and got messy since my thermostat was stuck closed, make sure you have a catch bucket for the coolant. The air box and battery must be removed to gain access to the thermostat housing. Three 10mm bolts were loosened and I swapped the old thermostat with the failsafe new product. Overall the job was very easy however I did loose a bolt and had to make another trip to Autozone for a replacement. Tip the thermostat has a air bleeder . Make sure that’s installed at the 11 o’clock position. Since the replacement of this part my Van has ran smoothly.
