Womala Constant Temperature Chamber OE 31319493 Thermostat Assembly for Volvo C30

Core Functions

• Engine Temperature Regulation: The thermostat valve inside the assembly opens and closes based on engine temperature (typically activating at 82–88°C, Volvo’s factory-specified threshold). When the engine is cold, the valve stays closed—redirecting coolant to circulate within the engine block to speed up warm-up (reducing wear and improving fuel efficiency). Once the engine reaches optimal temperature, the valve opens—allowing coolant to flow to the radiator for cooling, preventing overheating.
• Cooling System Sealing: The integrated EPDM gasket creates a leak-tight seal between the thermostat housing and the engine block. This prevents coolant leakage (a common issue with worn gaskets) and maintains consistent system pressure—critical for efficient heat transfer and avoiding air bubbles in the cooling system (which cause “hot spots” and overheating).
• Simplified Maintenance: As a pre-assembled unit, it eliminates the need to source separate thermostats, housings, or gaskets. This streamlines replacement, reduces installation time, and ensures all components work in sync (unlike mix-and-match aftermarket parts that may have incompatible dimensions).
• Corrosion Protection: The housing’s anti-corrosion coating (for aluminum variants) or chemical-resistant plastic resists degradation from coolant additives, road salts, and moisture—extending the assembly’s service life and preventing rust buildup that clogs the cooling system.
