Yes, Ecotec engines typically have a coolant drain plug, which is used to drain the engine coolant from the system for maintenance or repairs. The location of the drain plug can vary depending on the specific model and year of the engine. It's usually located at the bottom of the engine block or near the water pump. Always consult the vehicle's service manual for precise details regarding your specific Ecotec engine model.
On a Vauxhall Cavalier Ecotec 2.0L, the timing marks are located on the front of the crank pulley. It is marked under the cam.
If it is the 2.2 ecotec engine, it is located on the spark plug cover withe ecotec logo on it. It is a little square with wires and heat fins on it.
if you have the 2.2 liter ecotec engine, they are located right on top of the engine, they are located under the top black piece that says ecotec on it.
To bleed the coolant system on a 2000 1.8 Ecotec engine, first ensure the engine is cool, then remove the radiator cap. Start the engine and let it idle, allowing the thermostat to open. As the engine warms, check for air bubbles in the coolant reservoir; add coolant as necessary to maintain the proper level. Once the thermostat opens and the bubbles subside, replace the radiator cap securely to complete the process.
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.
Located near the oil filter
Located on the head of the engine, at the end of the intake or exhaust cam.
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.
