What do you need to know about torque wrenches?
If you don’t know what a torque wrench is, simply put, it is a ratchet that you set to a specific torque value. When it hits that torque value, as you initially set (say 85 ft-lbs), it will alert you in some way. Usually, torque wrenches for mechanics are the click-type where you will hear and feel a click as it reaches the set torque value.
What’s the best way to change an exhaust manifold gasket?
Spray down the manifold bolts with some penetrating oil. Because they are subjected to high heat, they will essentially weld themselves to the manifold. The oil will help you break that bond with your wrench. Use your socket wrench, with an extension if you need it, to take off the bolts. Be careful not to break off the bolts as you remove them.
When to recheck torque on aluminum rims?
So, if you can’t get access to a computer to google the exact number on your car you can use these general guidelines. The one thing to keep in mind is if they’re aluminum rims on either a truck or car, you should recheck the torque after 1,000 miles. They have a tendency to loosen up over time.
Can a gasket be removed from an intake manifold?
The gaskets will probably be sticky, so it will probably be necessary to gently pry the intake off of the cylinder head. If it puts up too much of a fight, go back and be sure all the fasteners are out. This is a very tricky step, because it’s so easy to have foreign objects fall into the intake or into the ports at this time.
What is the gasket that attaches to the cylinder head?
The first is the exhaust manifold gasket that attaches to the cylinder head. The other is a gasket that separates the exhaust manifold from the exhaust pipes. Please refer to your vehicle’s specific service manual for the exact materials and steps for replacing the exhaust manifold. Also, make sure to complete this job when the engine is cold.
What kind of gasket do you need for an exhaust manifold?
Whether it does or not, the exhaust manifold will require two new gaskets. The first is the exhaust manifold gasket that attaches to the cylinder head. The other is a gasket that separates the exhaust manifold from the exhaust pipes.
Where are the fasteners on an intake manifold?
Locate and remove all the fasteners attaching the intake to the engine. If your engine is a V type, they will probably all be on top. In that case, check your workshop manual, as there will be a recommended sequence for loosening the bolts.
