Removal
1. Although the intake manifold can be removed with the carburetor attached to it, it is still recommended to remove the carburetor first to improve access to the manifold fasteners (Chapter 11).
2. Disconnect the brake booster vacuum hose from the intake manifold (see illustration).

4. Remove the six mounting nuts, flat washers and lift the manifold off the studs. Be careful not to damage the gasket (see illustration).
5. If the gasket is damaged or in poor condition, replace it.
Installation
6. Reinstall in reverse order. Make sure the manifold and cylinder head mating surfaces are clean and in good condition. Secure all hoses and check for leaks at connections. Check the coolant level and top it up as necessary as described in Section 1.
