I am going to replace my coolant soon and was thinking should I replace the thermostat? Or just wait for it to die and replace it then?

Changing the t stat is relatively easy and cheap so if you can’t remember the last time you did it then it would be a good idea

If it's like my LBZ, it has 2.

Yes change them. You already drained coolant, and not talking that much more in cost. If you have my luck one will go bad, then you have to do a partial drain again.

There are two, a 180 and 185. Replace them both along with their rubber seals. There is also an O Ring on the crossover tube feeding the rear of the Thermostat Housing. Buy two, use 1. The second is a spare in case the first one gets chewed up in the swap.

Lube the first well when pushing back into the housing. Undiluted coolant will work.

I just replaced mine. There's a video on the tube abt doing it w/o disconnecting at the rear of the thermostat housing. That's the way I did it. A few more fasteners to remove and a couple of big elec connectors to disconnect but it went pretty quick.
