Thermostat Help

[blklml100]

Hi,
I have three trucks that I would like to know the part numbers for the thermostats. Some places I looked said that they were all the same part # for all three. Other places said they were different. I have a 2013 LML, 2017 L5p, and 2021 L5p. I want the OEM thermostats only, I found part #: 131-131 and 131-163. Will these work for all three or just the 2013 and 2017 like rockauto says?

Thanks for the help.

17-up are the same

01-16 are the 131-131 and 131-163.

I have not tried compared them side by side but pics do not show them as the same. Pretty sure the l5p does not use the thermostat to bloc the water pump bypass but i cant remember
