This Sierra thermostat kit, part number 18-3673, is described as a kit for V-4 crossflow engines and is labelled for the Ev-Jn V4 X-Flow application. Nothing further is stated about opening temperature, housing or what is in the kit, so check those details against your engine's service manual before you start the swap.
Our take
The V-4 crossflow label is the only fit detail given for this Sierra kit, so confirm your engine really is a V4 crossflow design before fitting it. The opening temperature is not stated, so check that against your engine's spec.
