Intake manifold (1.3 and 1.6)
2. Before removing the intake manifold, it is necessary to drain the coolant and disconnect the cooling hoses from the manifold.
3. On 1.3 engines, disconnect the wire from the coolant temperature sensor switch.
4. Disconnect the vacuum hose of the brake servo cylinder.
5. Now you can remove the intake manifold with or without the carburetor.
b. If you want to remove the carburetor first, refer to section 12 or 17.
7. To remove the manifold along with the carburetor, follow the instructions in the section that describes carburetor removal, but leave the nuts securing the carburetor to the manifold in place.

15. Remove the manifold flange gaskets.
16. Install the exhaust manifold in the reverse order. Replace the gaskets with new ones. If the flange connection of the downpipe with the manifold is leaking gases, you can try to correct the situation by installing 2 gaskets.
