To replace the exhaust manifold gasket on an Opel, first disconnect the battery and remove any components obstructing access to the manifold, such as the heat shield or exhaust pipes. Next, unbolt the manifold from the cylinder head, taking care to note the order and position of the bolts. Remove the old gasket, clean the mating surfaces, and install the new gasket. Finally, reattach the manifold, ensuring all bolts are torqued to the manufacturer's specifications, and reconnect any components you removed.
To replace the tappet gasket on an Opel Astra, first, ensure the engine is cool and disconnect the battery. Remove the valve cover by unscrewing the bolts and carefully lifting it off.

In a 2004 Opel Astra, the oxygen sensor is typically located in the exhaust system. There are usually two sensors: one is positioned before the catalytic converter (upstream) and the other is after the catalytic converter (downstream). The upstream sensor is often found on the exhaust manifold or just after it, while the downstream sensor is located further along the exhaust pipe. Always consult the vehicle's service manual for precise locations and specifications.

To change the welsh plugs (also known as freeze plugs) on an Opel Corsa Lite 1.3, you typically need to remove the engine components that obstruct access to them. This often includes the intake manifold and possibly the exhaust manifold, depending on the specific design of the engine. Additionally, you may need to drain the coolant and remove any associated hoses or components to ensure a clear working area. Once accessible, the old welsh plugs can be pried out and replaced with new ones.
The torque settings are normally included on a sheet when buying the gasket set.
