How to Remove the Exhaust Manifold Gasket on a Buick LeSabre

An exhaust leak can be frustrating. While exhaust leaks are often difficult to identify, worn exhaust manifold gaskets are often the problem. Removing worn exhaust manifold gaskets and replacing them with new gaskets on a Buick LeSabre is a small, inexpensive project for a do-it-yourself mechanic. With a few tools and a bit of time, you can remove failing exhaust manifold gaskets and replace them with new gaskets to increase the performance of your Buick LeSabre.

Instructions

1

Allow the engine and exhaust manifold to completely cool.

2

Disconnect any tubing from the exhaust manifold.

3

Loosen and remove the exhaust manifold bolts. If the bolts are resistant, use a penetrating oil to loosen them.

4

Remove the exhaust manifold and gaskets from the engine. The exhaust manifold in a Buick LeSabre is typically secured with two studs and two nuts.

5

Clean the gasket areas on both the engine and exhaust manifold with a scraper and wire brush to remove any remaining material from the old gasket. A clean, smooth surface ensures proper installation of the new gaskets.
