Fuel System The Fuel Injector And Fuel System Cleaning Process

Fuel system and fuel injection cleaning have become very popular since 1986. After 1986 most of the vehicles were built with fuel injectors in mind when building our cars and trucks. This is when everyone said goodbye to Carburetors. Fuel system cleaning was born and is now part of every maintenance check list out there in the automotive repair world.

Fuel Injection systems are a lot easier to work on and diagnose then the old carburetors. Carburetor rebuilding was quite expensive from the customers point of view. The parts and labor were averaging around $500 a job. I was cashing in on this carburetor craze since I was being paid commission and labor on every carburetor job I was involved with. But enough about me. Fuel injection and fuel injector cleaning is here to stay. What is all involved when the auto mechanic says, “You need your fuel system and fuel injectors cleaned.”

The fuel injection cleaning process is fast and does a very good job cleaning out the carbon build up inside your engines intake system. Actually it also depends on what type of fuel system cleaning the auto shop has in stock. Some shops had the regular 3 can cleaning system. While others have a very big and clumsy expensive machine they use. The fuel system and injector cleaning is a very simple process to perform and very expensive from a customers point of view.

I really liked using the 3 can system cleaning method. It involved adding one can to the fuel tank as a fuel additive. The second can was hooked up to a high pressure source and sprayed straight into the upper intake and upper plenum area and scrubbed by hand. The third can was hooked into the cars vacuum system where it was sucked down in to a vacuum source of the intake system and down around the intake and exhaust valves. There it would soak and bubble up for about 20 minutes. Then the auto technician would start the car after the 3rd can soaked and watched all the black carbon blow out the tailpipe! This 3 can fuel injection and injector cleaning process works very well in my opinion. Please have it done.

After changing the fuel filter, (for an additional charge) , I could not believe the power that was restored after this fuel system cleaning process and fuel filter replaced! Just slightly pushing on the accelerator the car wanted to jump right out of the shop and take off on its own. I think it cost around $80 or $90 bucks back then but it was well worth the money in my opinion!

Cooling System

Winter Time is near! And its time to check your cooling system. Or take  it to your local Auto Repair Shop and have your car serviced. My self, I would recommend having your cars cooling system checked at least once a year.


The things you want checked are, your antifreeze,your radiator cap,pressure test the system for leaks, and have a complete Flush and Fill. Just having a radiator drained and filled isnt a good idea.  The reason I say that is, all your replaceing is your antifreeze in your radiator. The Car is turned off during this procedure and your just mixing a small amount of new antifreeze with the rest of the gunk built up in the rest of the system. Maybe on a newer car with less than 12,000 miles you might, get by.

I remember reading a few articles regarding the New 100,000 Antifreeze. It sounds great but, they found it was not true. At least General Motors did. And after working on alot of their cars I found old contaminated antifreeze that was causeing premature wear on the internal and external parts. I just recently purchased a 2001 Blazer with only 84,000 miles and had to flush the cooling system 4 times to remove all the rust and gunk built up in the heater core. After that my heater now blows HOT!

To sum it all up, have your thermostat and antifreeze replaced.  And do not forget to have them pressure test your cooling system for leaks and do a complete Flush and Fill on your car or truck.
