How to fix coolant leak associated with the upper intake housing 2002 Buick LeSabre?

To fix a coolant leak associated with the upper intake housing on a 2002 Buick LeSabre, you will need the following tools:

- A set of wrenches

- A ratchet set

- A screwdriver set

- Pliers

- A funnel

- Coolant

Step 1: Locate the upper intake housing

Start by locating the upper intake housing. It is located on the top of the engine, and it is made of plastic.

Step 2: Remove the upper intake housing

To remove the upper intake housing, you will need to remove the following bolts:

- The four bolts that hold the upper intake housing to the lower intake manifold

- The two bolts that hold the upper intake housing to the throttle body

Step 3: Remove the gasket

Once the bolts have been removed, you can remove the upper intake housing. Be careful not to drop the gasket that is between the upper intake housing and the lower intake manifold.

Step 4: Clean the mating surfaces

Before installing a new gasket, you should clean the mating surfaces of the upper intake housing and the lower intake manifold. Use a degreaser to remove any oil or dirt from the surfaces.

Step 5: Install a new gasket

Place a new gasket between the upper intake housing and the lower intake manifold. Make sure the gasket is properly seated.

Step 6: Reinstall the upper intake housing

Reinstall the upper intake housing by tightening the four bolts that hold it to the lower intake manifold and the two bolts that hold it to the throttle body. Do not over-tighten the bolts.

Step 7: Fill the radiator

Fill the radiator with coolant until the level reaches the "Full" mark. Replace the radiator cap.

Step 8: Start the engine and run for a few minutes.

- While the engine is running, check for leaks around the upper intake housing. If there are no leaks, turn the engine off.

Step 9: Check the coolant level

Check the coolant level again. If necessary, add more coolant to bring the level to the "Full" mark.

Your coolant leak should now be fixed. If the leak persists, you should take your car to a professional mechanic.
