Sierra Thermostat Kit 18-3674 for Ev-Jn V6 X-Flow

Brand:
Sierra
Part no:
18-3674

Where to buy

This is the Sierra thermostat kit under part number 18-3674. It is labelled for the Ev-Jn V6 X-Flow, so it is meant for engines of that description rather than as a general purpose thermostat. Opening temperature is not stated here, so confirm it against your engine's service documentation before you rely on this kit.

Our take

The X-Flow V6 label on 18-3674 tells you which engine family Sierra built this thermostat kit around, so check the engine match and not just the part number. Opening temperature is not given, so confirm it from the service manual.
