How to Install a Remote Oil Filter

Installing the Filter


Remove the existing oil filter and recycle it properly according to local legal guidelines for used household chemical management.


Install the replacement filter head unit on the engine by turning the filter head retaining nut. Do not tighten down yet to allow for later adjustments to the fittings. Lubricate the seals well with a light coat of clean engine oil.


Install the provided 90° fitting into the side port of the replacement head unit. Ensure the lock nut is threaded all the way down on the fitting.


Install either the 45° adapter or the straight adapter according to your engine design into the bottom port of the replacement head unit.


Tighten the filter head retaining nut the same way you would if you were installing a new oil filter and tighten down all fitting connections.


Secure the remote filter head to the mounting bracket using the fasteners provided. Do not install a fastener in the far left hole which is reserved for mounting the bracket to the frame.


Bolt the bracket to the frame in a convenient location using the through bolt provided in the kit.


Measure the length of lines required. Cut the provided 8 foot line down to the needed length with a hacksaw.


Install the compression fittings onto the supply and return lines. Apply clean engine oil to the threads of the inside compression fitting before attaching the nipple assembly into the exterior screw nut.


Blow out the lines from each end with shop air to remove all debris. Failure to do this might cause severe engine damage.


Install the oil lines between the filter head assembly and the remote filter head. You may need to wrap the lines with thermal shielding if they run very near high heat components. Do not allow them to come near moving parts.


Fill the filter head with oil.


Install the new oil filter onto the filter head.


Make sure all fittings are tight and start your truck. Watch the oil pressure gauge carefully. If the gauge does not read properly or if the light doesn't turn off within a couple of minutes then you may need to add some oil to the system to make up for the new volume the oil now has to cover.


Once the oil pressure has normalized and the light has turned off check the system for any oil leaks

Tips and Warnings

  • Seriously consider installing a cooling system for the remote oil filter. There is a reason the original filter was placed where it was, to help keep the oil cool. Cooking your oil could kill your engine.
  • Inspect the remote oil filter system periodically and make any adjustments you need to keep the system from leaking.
  • You now have more space for the oil to fill but still need to maintain pressure. You may need to add a little additional oil to the engine when you change your oil in order to accommodate the extra volume
  • Allow the engine to cool for at least 2 hours before performing any task involving the oil system. Even if the engine's metal is cool the oil may still be retaining heat.
  • Performing this modification may void your vehicles power-train warranty so check with your vehicles manufacturer before performing this or any task which might void your warranty.
  • Changing the oil filter on a larger truck engine, such as a Dodge Ram 3500 SLT W/ 5.9L Cummins Turbo Diesel Engine, can seem like a hassle. Installing a remote oil filter, like a Pacbrake relocation and filter kit, can help alleviate the trouble by placing the oil filter in a position which might be easier to access without having to get under the vehicle. Just remember to also consider a cooling system for the remote filter setup so as not to cook your oil with engine compartment heat. Your vehicle might have different procedures and the installation may vary according to your relocation kit package.
