Things You'll Need:
- Wrench
- Screwdriver
- Gasket scraper
- Intake manifold gaskets
- Gasket sealer
- Torque wrench
- Antifreeze
-
Step 1
Drain the radiator and disconnect the upper radiator hose from the intake manifold. A single drain bolt is located on the interior side of the bottom of the radiator and can be removed with a wrench. The upper radiator hose attaches to the front of the manifold with a single hose clamp. Loosen the screw on the clamp with a screwdriver, then pull the hose away from the manifold to disconnect it.
-
Step 2
Remove the intake manifold's retaining bolts with a wrench, then lift the manifold off of the engine to remove it. The bolts are located on the top of the manifold.
-
Step 3
Peel the old intake manifold gaskets off of the manifold, then clean the gasket's mating surfaces. Each gasket's mating surface, meaning the portion of the engine that the gaskets rest on, must be cleaned of any old gasket material or other debris prior to installing the new gaskets. To clean the surfaces, scrape them clean with a gasket scraper.
-
Step 4
Install the manifold's end gaskets. The end gaskets are the shorter of the four intake manifold gaskets, and are made of cork. Coat one side of each gasket with gasket sealer, then place the coated side of both gaskets onto the engine block. Coat the top of both gaskets with gasket sealer.
-
Step 5
Install the gaskets which seal the manifold to the cylinder heads. These gaskets are not head-specific, meaning that either of the two gasket can be used for either cylinder head. Coat the gaskets with gasket sealer and install them in the same manner used to install the end gaskets.
-
Step 6
Slowly lower the intake manifold onto the top of the engine so that the gaskets to not slip under the weight of the manifold. Slide each of the manifold's retaining bolts through the manifold and into the cylinder heads. Use a torque wrench to tighten each bolt to 12 to 15 pound-feet of torque.
-
Step 7
Slide the upper radiator hose onto the front of the intake manifold, then tighten the screw on the hose clamp with a screwdriver to secure the hose in place.
-
Step 8
Reinstall the radiator's drain bolt with a wrench, then remove the radiator cap. Fill the radiator with antifreeze and install the radiator cap to complete the repair.
