Who makes the OEM thermostat

Flushing my radiator so ill replace the water pump and thermostat while im in there. I know Aisin makes the WP, anyone know who makes the thermostat?

 

Here's the part #160310P010, comes with the housing.
Thermostat

 

Rockauto sells aisin thermostat https://www.rockauto.com/en/catalog....0l+v6,1432865,cooling+system,thermostat,2200

 

NTC-TAMA

 

I didn't know it was branded Toyota. Cool. Thanks!

 

Any good vids on replacing thermostat and/or water pump?

 

Amazon also sells it......$35 today

 

The seal between the thermostat and housing started leaking this weekend. I plan to pull it off, inspect and order a new one if necessary. Is it harder than clamping the hose, removing hose, remove bolts, pull thermostat and seal, install new thermostat with new seal, install in revers order and top with coolant? Just curious if I should expect anything more.

Thanks!
