Chevy 5.3 Intake Manifold Torque Specs That You Can’t Resist

Is your chevy’s performance degraded and you’re looking to improve it? Want to upgrade it to the latest 5.3 intake manifold? But is the upgrade worth it?

So, what are chevy 5.3 intake manifold torque specs?

The latest chevy 5.3 intake manifold increased its torque and temperature capacity. It is now much higher than its previous models. Up to 10-15 torque higher would make it absorb more stress without tearing apart. The increased temperature of the bolts would make it operate properly even in hot weather conditions.

This is just the tip of the whole discussion of specs. You have to read the whole article. Then you’ll know why it is not possible to resist buying it.

The benefits include-

  • 1-2mpg gain
  • Quicker acceleration
  • 10-15 horsepower gain
  • Improved throttle response
  • 10-15 torque gain
  • Cooler engine temperature
  • Increased the engine sound

Who wouldn’t want to get such improved performance? You shouldn’t take the time and upgrade it as soon as possible. You wouldn’t regret upgrading it.

Chevy 5.3 Intake Manifold Torque Specs

The latest chevy 5.3 revolutionized its intake manifold by introducing the LS engine. Their new intake manifold just crushed their old models in performance. Without seeing the specs, it is really hard to believe. They are described below-


It is a rotating metal object that contains cams. Reciprocal motion is being converted from rotational motion by it.

Retainer bolts seal the oil passageway for the oil to pass through to the engine.

Sensor bolt ensures the air and fuel to combat at the exact time in the combustion engine.

Sprocket bolts ensure an accurate axial load. Their purpose is to keep the gears synchronized with the crankshaft. So, this ensures the engine operates correctly.

Camshaft Bolts Torque Amount
Retainer Bolts18 lb/ft
Sprocket Bolts26 lb/ft
Sensor Bolt18 lb/ft


A crankshaft’s job is to ensure the proper operation of the engine. Also, rotational motion is converted from linear motion by it.

A balancer bolt helps the vehicle to absorb vibration.

Bearing cap bolts seal the place where the bearing is contained to stop particles from entering. 

Bearing cap studs can absorb much more torque. Because it doesn’t have to get twisted while tightening it.

Position sensor bolt manages the rotation speed and position of the crankshaft. This is by attaching the sensor tightly.

Crankshaft BoltsTorque Amount & Degrees
Balancer Bolt: (Installation Pass)240 lb/ft
Balancer Bolt (First & Final Pass) 37 lb/ft & 140 degrees
Bearing Cap Inner Bolts (First & Final Pass)15 lb/ft & 80 degrees
Bearing Cap Outer Studs (First Pass & Final Pass)15 lb/ft & 53 degrees
Bearing Cap Side Bolts18 lb/ft
Position Sensor Bolt18 lb/ft

Connecting Rod Bolts

They keep the two halves together of the bottom end bearing under a lot of stress. It has to have enough torque. It also needs enough heating capacity.

The 1st design has a single mark on its head and has no retaining sleeve. On the contrary, the 2nd design has two marks on its head and also has a retaining sleeve.

Connecting Rod BoltsTorque Amount & Degrees
Bolts - First Design (First & Final Pass)15 lb/ft & 60 Degrees
Bolts - Second Design (First & Final Pass)15 lb/ft & 75 Degrees

Cylinder Head Bolts

It helps connect the cylinder head, cylinder head gasket, and engine block. Tightening it would help seal the ambient air, lubricant channels, and combustion chamber. 

It has to have a lot of heating and torque capacity to keep all these together.

Cylinder Head Bolts Torque Amount & Degrees
Bolts (M8 Inner Bolts in Sequence)22 lb/ft
Cylinder Head M11 Bolts (First Pass & Second Pass)22 lb/ft & 90 degrees
Cylinder Head M11 Bolts (Final Pass - Except For Medium Sized Bolts at Front & Rear) 90 degrees
Cylinder Head M11 Bolts (Final Pass - Medium Sized Bolts at Front & Rear)50 degrees

Engine Bolts

Engine bolts absorb all the vibration and force that the engine tends to do while running. It would help transfer all that heat and hit away from the engine. The bolts also transfer the load of its belt to the engine.

Flywheel bolts help absorb and smooth out the pulses of your engine.

Flywheel to torque converter bolts helps the engine to move independently on its own without the transmission.

Cover bolts seal the cover of your engine to hold the front crankshaft. It also keeps debris and dirt from the timing chain.

Engine BoltTorque Amount 
Front Cover Bolts18 lb/ft
Flywheel Bolts74 lb/ft
Rear Cover Bolts18 lb/ft
Flywheel-to-Torque Converter Bolts44 lb/ft
Valley Cover Bolts18 lb/ft

Oil Pan Bolts

Oil pan covers the crankcase. It works as the reservoir for the oil that goes through the engine to lubricate the parts. The bolts tighten it for the oil to flow without any disruption.

Oil Pan Bolts Torque Amount 
M8 Bolts (Front Cover)18 lb/ft
M6 Bolts (Rear Cover)106 lb/in

Valve Rocker Bolts

Valve rocker’s main job is to transfer the pushrod motion to its corresponding valve. The bolts help keep it properly covered to stop other things from entering into the transfer process.

Valve Rocker Bolts Torque Amount 
Arm Bolts22 lb/ft
Arm Cover Bolts106 lb/in

Water Pump Bolts

Water pump is just beside the engine block. It circulates antifreeze or coolant throughout the whole engine block. It helps keep the temperature at an operating level and stops the engine from heating. 

Thus, the bolts need to have the capacity to stand that much torque to keep the coolant flowing.

Water Pump Bolts Torque Amount 
Pump Bolts (First Pass)11 lb/ft
Inlet Housing Bolts11 lb/ft
Pump Bolts (Final Pass)22 lb/ft
Pump Cover Bolts11 lb/ft

Other Engine Parts or Bolts

Exhaust manifold bolts help the manifold to slide. And they let the gasket stay on top of the engine. 

Fuel injector rail bolts help the rail stay in place for the fuel to run through it.

Intake manifold bolts help to keep the temperature minimum while sealing the manifold.

Knock sensors protect the engine from the pressure created by the fuel and air mixture.

Other Bolts Torque Amount 
Fuel Injection Fuel Rail Bolts89 lb/in
Exhaust Manifold Bolts18 lb/ft
Intake Manifold Bolts (in sequence)89 lb/in
Knock Sensors15 lb/ft

You can clearly see the torque and degree these parts can hold. The higher the torque the higher stretch and stress it can absorb. Also, the higher degree means that it has a higher heat capacity.

It is clearly more than its previous models. It would ensure long-lasting better performance. It has overall better specs than the rest of the intake available in the market for chevy. 


What are Torque Specifications?

Torque refers to the rotational force applied to a point. Torque specifications are the amount of force that is needed to install that hardware.

How Important is Torque Sequence?

It helps to evenly distribute the pressure to keep the parts from facing overstress or overheating. It also keeps the parts of the engine to stay in the proper place.  

Can You Over Torque Intake Manifold?

You shouldn’t do it. It would cause the warp of the manifold. It will also damage the seal. Which then would need to be repaired and cost a lot.


Hope you got a clear idea about chevy 5.3 intake manifold torque specs.

This latest model of 5.3 intake manifold is the best in the market for your chevy. It is worth the money and there is simply no reason not to buy it.

Have a good day!
