Mitsubishi Outlander Thermostat Replacement Malaysia
The thermostat regulates engine operating temperature by controlling coolant flow to the radiator. A stuck-open thermostat causes the engine to run too cold, reducing fuel economy and increasing emissions. A stuck-closed thermostat is more dangerous — the engine overheats quickly. In Malaysia's heat, thermostat failure tends to lean towards the stuck-closed scenario during extreme traffic jams. Thermostat replacement is a relatively simple and affordable job and is often done as preventive maintenance when the coolant is being flushed.
Outlander Thermostat
- Replace at 100,000 km or if temperature gauge reads abnormally — common symptom of stuck thermostat
- Stuck-closed thermostat: engine overheats — requires immediate roadside stop
- Replace with OEM-spec thermostat and replace coolant at the same time — a combined service is cost-effective
