HOW TO CLEAN DIESEL FUEL INJECTORS WITH SEA FOAM

CLEANING DIESEL FUEL INJECTORS FOR PEAK PERFORMANCE

Diesel engines are renowned for their durability and efficiency, but maintaining optimal performance requires regular attention to key components, notably the fuel injectors.

Over time, fuel injectors can accumulate deposits that hinder fuel flow, leading to reduced engine efficiency, increased emissions, and potential engine damage.
Regular injector cleaning is essential to ensure your engine runs smoothly and efficiently.

COMMON PROBLEMS

Fuel injectors deliver precise amounts of fuel into combustion chambers. When functioning correctly, they ensure optimal combustion, resulting in efficient power generation and reduced emissions. However, the high temperatures and pressures within diesel engines can cause fuel to oxidize and form deposits on injector nozzles.

These deposits can disrupt fuel spray patterns, leading to:

Increased emissions

Irregular fuel delivery can cause noticeable declines in engine performance.

loss of power

Clogged injectors can cause incomplete combustion, leading to increased fuel consumption.

Increased emissions

Deposits can cause unburned fuel to exit the exhaust, elevating emissions.

Engine knocking

Uneven fuel distribution can lead to knocking or pinging sounds, indicating potential engine damage.

How to clean diesel fuel injectors

CLEANING DIESEL FUEL INJECTORS WITHOUT REMOVING PARTS

Traditionally, cleaning fuel injectors requires removing them from the engine — a time-consuming and technically demanding process. However, with advancements in fuel additives, it’s now possible to clean injectors without disassembly. Sea Foam Motor Treatment offers a straightforward solution to this problem. Read the steps below, or watch the video to learn how.

PREPARATION

Make sure your vehicle is parked on a level surface with the engine off and cool.

FIND THE FUEL FILTER

Locate the primary fuel filter. In many diesel engines, this is easily accessible, but consult your vehicle’s manual if unsure.

ADD SEA FOAM TO THE fuel FILTER

Remove the fuel filter and empty its contents. Fill the fuel filter with straight Sea Foam Motor Treatment, then reinstall the fuel filter securely.

START THE ENGINE

Start the engine and let it idle for about two minutes. This allows the Sea Foam to circulate through the injectors.

LET IT SOAK

Turn off the engine and let it sit for about 15 minutes. This soaking period helps dissolve carbon deposits.

START AND DRIVE

Restart the engine and drive for about 30 minutes, preferably under varied speeds and loads, to ensure thorough cleaning.

Following these steps effectively cleans the fuel injectors, combustion chambers, and compression rings without the need for disassembly.

pREVENTATIVE MAINTENANCE WITH SEA FOAM

Add Sea Foam to your fuel tank every 3,000 miles to maintain injector cleanliness and be sure to use high-quality diesel fuel to minimize the introduction of contaminants.
It’s also a good practice to replace fuel filters per the manufacturer’s recommendations to prevent debris from reaching the injectors.
By incorporating these practices and with a little help from Sea Foam Motor Treatment, you can ensure your diesel engine operates its best, delivering reliability and efficiency for years to come.

“I have two older vehicles that have been restored and I use sea foam regularly in both. I try to use fuel without ethanol but on the road it is hard to find so I add sea foam to every tank of fuel. My work truck is a diesel and i use sea foam to help keep my injectors clean. My cars are a 1931 ford and a 1955 BelAir Chevrolet 2 door hardtop.”
