Thermostats in Astana
The thermostat holds the engine's operating temperature: on a cold engine it stays closed and keeps coolant in the small circuit, and once warm it opens to send coolant to the radiator. A faulty thermostat is a common cause of both overheating and a cold heater in winter — very noticeable in Astana. We select thermostats and housings by VIN for your engine — original and proven aftermarket in stock in Astana.

Types of thermostats
A classic wax thermostat opens at a set temperature — typically somewhere in the 80–95 °C range depending on the engine. It comes as a separate insert or as an assembly with the housing. Many modern engines use an electronically controlled (map-controlled) thermostat with a heater: the ECU can open it earlier under load. Such thermostats are often sold only as an assembly with the housing.
Signs of failure
Stuck open: the engine takes long to warm up, the gauge doesn't reach its usual position, the heater blows lukewarm in winter, fuel use rises. Stuck closed: the temperature climbs quickly to overheating, with the upper hose hot and the radiator cold. There's no fixed replacement interval — the thermostat is replaced on condition, often together with the water pump or a scheduled coolant change per the manufacturer.
How to choose
What matters most is matching the opening temperature, dimensions and type (insert, with housing, electronic). A thermostat with a different opening temperature changes the engine's thermal regime. Select by VIN: we show original and aftermarket from Wahler, Mahle, Gates, Vernet and Tama, plus the matching gasket.

FAQ
A common cause is a thermostat stuck open: the engine never reaches operating temperature. Coolant level and air locks are also checked.
Not recommended: the engine will run colder than designed, warm up worse in winter and use more fuel. Fit one with the catalogue opening temperature — we select by VIN.
It depends on the engine: on some the insert is replaced separately, on others it's sold only as an assembly with the housing. VIN selection shows the right option.
