Here is a quick guide to help you change your gasket easily.

  1. Step 1: Let Engine Cool Off. Before you do anything to the exhaust manifold, let your engine cool down if you have just been driving.

  3. Step 3: Scrape Old Gasket Off.
  4. Step 4: Set New Gasket.

What does an exhaust flange do?

What is the Exhaust Pipe Flange (Donut) Gasket all about? Your exhaust system runs from the exhaust manifold to the tailpipe. It is made in several different pieces through various arrangements depending on your vehicle model. It fills the gap in the flare and creates a smooth passageway for the exhaust to go through.

Do exhaust manifold gaskets need sealant?

You shouldn't need to use sealant on the gaskets. Most exhaust manifold gaskets either come with their own sealant (like Fel-Pro's do with the silver looking stuff), or they are metal and don't require it either. If you don't, you could have slight low spots in your manifold which could allow for exhaust leakage.

How does split flange work?

A split flange is a type of flange that can be easily installed on pre-existing piping. It is made up of two interlocking pieces that fit securely together using nuts and bolts or welding it into place.

  4. Raise the vehicle and safely support.
  5. Attach the front exhaust pipe to the exhaust manifold.

What is a flange in a car?

A flange is an external or internal ridge, or rim (lip), for strength, as the flange of an iron beam such as an I-beam or a T-beam; or for attachment to another object, as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera; or for a flange of a rail car or tram wheel.

Do exhaust gaskets expand?

Since the castings are new and machined surfaces are smooth, the exhaust manifold can fit tightly against the cylinder head without leaks. This allows expansion and contraction of the exhaust manifold to take place without damaging the fiber side of the gasket.

How do you change an exhaust manifold?

Step 1: Attach the new exhaust manifold gasket onto the studs on the cylinder head. Step 2: Install a new gasket between the bottom of the exhaust manifold and the exhaust pipes. Step 3: Attach the exhaust manifold to the exhaust pipes below the vehicle. Step 4: Slide the exhaust manifold onto the cylinder head studs.
