This is the Sierra 18-3561 thermostat, rated at 143 degrees. It is cross-referenced to BRP part number 436195. The maker gives little else about it, so compare the rating and the BRP number against your engine's parts list before relying on it.
Our take
The 143 degree rating and the BRP 436195 cross-reference are what identify this Sierra thermostat. Put those two numbers next to the one in your engine's parts list; if they differ, it is not the part you need.
