Keywords

💡Fuel Filter

A fuel filter is a critical component in any diesel engine that prevents contaminants and debris from entering the engine by filtering out harmful particles from the fuel. In the video, the host demonstrates how to replace the fuel filter on a 6.6 liter Duramax engine, emphasizing its importance for maintaining engine health and performance. The fuel filter is located near the priming button and fill filters, and the process of replacing it involves disconnecting sensors and disposing of old diesel fuel.

💡Duramax

Duramax is a brand of diesel engines produced by General Motors for use in light to medium-duty trucks. The video specifically addresses the 6.6 liter Duramax engine, which is known for its durability and power. The tutorial provided is tailored to this engine type, showcasing the unique steps and considerations for replacing the fuel filter in this particular engine model.

💡Priming Button

The priming button is a part of the fuel system that is used to draw fuel into the engine when starting a diesel vehicle. In the script, the priming button is mentioned as a reference point for locating the fuel filter, indicating its proximity to the filter and the importance of the fuel system's components in the overall functionality of the engine.

💡Sensor

A sensor in the context of a diesel engine is a device that detects and measures changes in physical conditions such as pressure, temperature, or flow, and sends this information to the vehicle's control module. In the video, the host instructs viewers to disconnect a sensor connected to the bottom of the fuel filter, highlighting the need to safely handle these components during the replacement process.

💡Inner Fender Well

The inner fender well is the area inside the wheel well of a vehicle, which houses various components including the fuel filter in the case of the Duramax engine. The video mentions removing the inner fender well for better access to the fuel filter, illustrating the practical steps taken to facilitate the replacement process.

💡Oil Wrench

An oil wrench, also known as a filter wrench, is a tool specifically designed to remove and install oil and fuel filters without damaging the filter or the vehicle. The script describes using an oil wrench to remove the old fuel filter, emphasizing the use of appropriate tools to ensure a successful and safe maintenance procedure.

💡Diesel Fuel

Diesel fuel is the type of fuel used in diesel engines, known for its higher energy density and lower volatility compared to gasoline. The video script includes a step to dispose of old diesel fuel, which is a crucial step in the fuel filter replacement process to prevent contamination and ensure the engine runs efficiently with clean fuel.

💡O-Ring

An O-ring is a loop-shaped gasket that is used to create a tight seal between two or more parts. In the context of the video, the host mentions an O-ring attached to the fuel filter, which must be lubricated with engine oil before reinstallation. This step is essential to ensure a proper seal and prevent fuel leaks.

💡Engine Oil

Engine oil is a lubricant used to reduce friction between moving parts in an engine. In the script, the host advises lubricating the O-rings with engine oil before installing the new fuel filter. This practice helps to create a better seal and protect the new filter from damage due to friction.

💡Bleed Screw

The bleed screw is a small valve used to release air from the fuel system, ensuring that the fuel system is free of air bubbles which can cause poor engine performance. The video describes the process of using a 13-millimeter socket to remove the bleed screw and then reattaching it after the new filter is installed, which is a crucial step in the fuel filter replacement process.

💡Pressurize

Pressurizing the fuel system involves forcing air out of the system and replacing it with fuel to ensure proper operation. After installing the new fuel filter, the host instructs viewers to pump the system a few times to pressurize it, which helps to remove air bubbles and prepare the engine for starting.

what's going on guys today I'm going to

show you how to replace a fuel filter on

a 6.6 liter Duramax stay tuned so this

is where your fuel filter is actually

located right there with that priming

button is and the fill filters right

below it and there'll be a sensor

connected to the bottom of it as well

all right guys so this is something you

don't have to do I'm gonna head and take

off this inner fender well but you can

access the field filter from the top of

the engine this just makes it more

convenient for me in the video I get a

lot more access to what I'm able to do

this you got these little body Clips

that pop out right here alright so first

what you're going to want to go ahead

and do is just disconnect this sensor

right here via water and feel separate

or sensor right here right next

go ahead and get your your oil wrench

just like that alright so next once

you're going to go ahead and do is just

disposal this old diesel fuel you're not

going to want to reuse that alright next

we going to want to go ahead and pull

this off do not strip that part right

there if you do you're going to be in

trouble you have to buy a new one go

just comes out like that

and there'll be an o-ring attached to

this part right here here's a new oil

filter pretty standard it also comes

with instructions make sure you read the

instructions right here we actually have

a little diagram right here on you know

exactly how it's actually supposed to be

put back together alright so can have a

little o-ring in a big o-ring

I always like to I always like to

lubricate these rings here with some

engine oil or whatever you got it's

always good to lubricate this stuff when

you put it back on it's actually a must

alright alright next I'm gonna go ahead

and put the center back on

okay what's that uh once that fuel

filters off there will be the rubber

fitting that comes with the fuel filter

so make sure you pull that off first so

you don't double up on that it will not

go on properly it's time to install the

new field filter

all right so people like to use

screwdrivers to pull out that bleeder

screw I don't really like it because

I've you know stripped those things

quite a bit so I like to use a 13

millimeter small socket just to be able

to get back there so I'm not stripping

anything alright once you've actually

built that fuel filter just push down on

that just a little bit more to get some

of the air bubbles out like that and

then that's when you're going to want to

go ahead and just tighten that back up

once you got that blue bleeder screw

back on we'll just release it just pump

it a few times to pressurize the system

a little bit and you should be good to

go

so hope this video is helpful if there's

something I might have forgotten in the

video make sure that you ask the

question in the comment below make sure

I get back with you and don't forget to

subscribe as I'm always posting new

upgrades updates and fixes on my Duramax

but as always thanks for watching and

have a great day
