The thermostat is located in the right corner of the car, there will be a connection that has a y-split look to it. It allows the coolant to go into the block. When replacing this, make sure to buy the thermostat and new gasket (sold separately). You must perform this by draining the coolant out of the system first, while engine is cold, because the system is under 15 psi.
To test the Engine Coolant Temperature (ECT) sensor on a 2.2L Ecotec engine, first, locate the sensor, which is usually found near the thermostat housing. Use a multimeter to check the resistance of the sensor at various temperatures, comparing your readings to the manufacturer's specifications. Additionally, you can monitor the ECT sensor's output voltage using a scan tool or multimeter while the engine runs to ensure it changes appropriately with temperature. If the readings are outside the specified range, the sensor may need replacement.
They are located below the black plastic where you see the "ECOtec" logo on the engine top. You have to remove screws and pull out the ignition coils to see the spark plugs. By the way GM's 2.2 Ecotec use direct ignition, so there's no spark plugs wires.

The normal operating temperature for a Vauxhall Calibra 2.0 16v ECOTEC typically ranges between 85°C to 95°C (185°F to 203°F). Maintaining this temperature range is crucial for optimal engine performance and efficiency. If the temperature consistently exceeds this range, it may indicate issues such as cooling system failure or a malfunctioning thermostat.
The clutch bleed valve on a 2.2 liter Chevy Ecotec engine is located on the slave cylinder. To find the slave cylinder remove the battery, as it is mounted underneath the battery tray.
The Vectra, particularly the first generation (A), featured several engine types, primarily from the Ecotec family. Common engine names include the 1.6L Ecotec, 1.8L Ecotec, 2.0L Ecotec, and the 2.5L V6 Ecotec. Additionally, there were diesel options like the 1.7L and 2.0L turbo-diesel engines. The Vectra B, the successor, also continued with similar Ecotec engine offerings.
