Oil Pan Torque Sequence

You are currently viewing Oil Pan Torque Sequence

The oil pan torque sequence is the proper way to torque down the bolts that go through your oil pan to secure it.

A rod bolt will typically be left loose and tightened last, so you need to know how much thread depth is gone before you tighten it down. This article covers the torque sequence for installing an oil pan.

This sequence is based on using a torque wrench and ensures that all six bolts are tightened in a logical order.

Following this sequence when tightening oil pan bolts is vital to avoid over-torqueing and potential engine damage.

What Is Oil Pan Torque Sequence

What Is Oil Pan Torque Sequence

The oil pan torque sequence is a specific way of tightening the bolts that attach the oil pan to the engine. This is important because it can hold the oil pan in place and keep it from vibrating, affecting how well the engine performs.

The oil pan torque sequence begins by torqueing down the bolt that attaches the oil pan to the engine block. Next, you should tighten the bolt that attaches the oil filter to the oil pan.

Finally, you should tighten down the bolts that attach the oil pump to the oil pan.

Oil Pan Torque Specs Ls

LS oil pan torque specifications can vary from engine type to manufacturer, engine size, and even application. However, it is important to note that these specs are not the same for every year or model.

In order to proactively prevent damage to your vehicle, in addition to saving money on warranty repairs later down the road, it is recommended that you find out what your oil pan torque spec is. Here are the LS oil pan torque specs – 

  1. With the engine off, start with the drain plug
  2. Using a torque wrench and an extension, torque down to spec 
  3. Next, tighten the oil filter adapter bolts at the bottom of the pan – 3/4 to 1 turn after contact with the pan
  4. Finally, torque down the central oil gallery bolt on top of the block – use a crisscross pattern
  5. For most models and applications, this is all that is required to torque your LS oil pan properly.
