Exhaust headers and manifolds collect exhaust gases from the engine.
Exhaust manifold gaskets helping hand seal the exhaust manifold against the cylinder head to assure steady exhaust back impulse and prevent exhaust gases from escaping prior to passing complete the catalytic converter. Whether the exhaust manifold gaskets split or come loose on your One thousand nine hundred ninety seven Ford F150, you Testament itch To possess them replaced or spend a date or two replacing them yourself.
Instructions
1. Launch with a brumal engine. Manipulate the socket establish to loosen the exhaust manifold bolts. Loosen one partially, then maneuver to the beside and so on until you own loosened them all partially, giving you approximately 1/4- to 1/2-inch extent between the bolt heads and the manifold itself. Accomplish not completely remove the bolts.
2. Capitalization the pry bar to carefully pry the manifold gone from the cylinder mind. Manipulate worry not to pry against anything breakable, such as Glimmer plugs, heater hoses or exhaust shields. (You Testament commitment to pry in distinct places before you can access the deficient gaskets.)
3. Grab the senile gasket with the thorn nose pliers and pull it absent of the breach between the manifold and cylinder mind. This may wish diverse attempts before you get it completely out. Make sure not to leave any pieces of the gasket behind. Pry the manifold away from the head until the gasket drops completely into position.5. Tighten the exhaust manifold bolts back down with the socket set.6.
It may be necessary to pry with one hand and operate the pliers with the other. This process can take several hours per side.4. Insert the new gasket in between the manifold and cylinder head.
Repeat Steps One through on the opposite side.
7. Start the engine and wait for it to arrive normal operating temperature. Do not rev the engine.
8. Put the gloves on and re-torque each of the manifold bolts with the socket wrench. Use caution, as the exhaust manifold is extremely hot and can deliver second or third degree burns on contact, even through the gloves.
9. Rev the engine and listen for any signs of an exhaust leak, which will sound similar to an engine knock. If any such noise is evident, tighten the bolts again until the noise goes away.
