This is a Sierra thermostat with a seal, part 18-1507, marked 60Dg for V4-6 engines and cross-referenced to BRP 335981. Nothing more is stated about its flow or housing, so use the part number and the BRP number to check it against your existing thermostat. The two numbers are the reliable way to match it.
Our take
The 60Dg marking and the BRP 335981 cross-reference are the facts to match on this Sierra thermostat, and both sit in its name. Compare them with your current part before fitting.
