Triton Thermostat
- Thermostat stuck open: engine never reaches operating temp — fuel economy suffers
- Thermostat stuck closed: engine overheats — very dangerous in diesel
- Replace thermostat preventively at 100,000 km
- Always replace with OEM spec thermostat — cheap units fail quickly in diesel heat
