DESCRIPTION
Restore proper temperature control to your early BMW E46 318i with this OE-quality thermostat from Mahle — the original manufacturer behind the Genuine BMW part.
This thermostat is designed specifically for E46 318i models built prior to September 2001, and helps ensure fast warm-up, stable running temperatures, and optimal engine efficiency. Manufactured to exacting OEM standards, this unit is identical to the Genuine BMW item, but comes boxed under the Mahle brand — offering excellent value without compromise.
Whether you’re chasing an intermittent coolant warning, replacing a failed unit, or simply performing preventative maintenance, this thermostat is a high-quality, direct-fit solution.
HELPFUL TIPS
Make sure you have enough coolant on hand before starting the job.
