How to disassemble Landi LPG injectors : guide, step by step and demonstration video, for disassembling LPG injectors on Landi systems.
Unfortunately, the LPG systems that we find along our way often deliver dirty and poor quality LPG . Poor quality LPG ends up dirtying the injectors and compromising the efficiency and stability of the entire system. To clean dirty LPG injectors we can rely on additives or we can try to carry out a more invasive intervention that involves disassembling the LPG injectors .
Our guide on how to disassemble LPG injectors can also be useful for those who find themselves with broken LPG injectors and want to replace them without incurring mechanical labor costs.
How to disassemble Landi LPG injectors
The disassembly of the LPG injectors must be performed with the engine off and stopped. When the engine is stopped, no gas circulates. Before performing this surgery, you must be sure that you have the necessary skills to complete the mechanical replacement. If you have strong insecurity, contact the mechanic while, if you only have some fears, it is a relatively simple operation!
Complete instructions for disassembling the injectors are available in the video below where the plant in question is a Landi.
Once disassembled , the LPG injectors must be cleaned with products that are not excessively oily. There are those who recommend cleaning the injectors with compressed air or those who even recommend kerosene. Based on the condition of your injectors you can draw your own conclusions. Our advice is to use a cleaner for LPG injectors , there are different types on the market and there is also a good choice on Amazon.
Damaged or broken LPG injectors must be replaced. To understand if you need to replace only one LPG injector or all of them, you can take the car to the mechanic and ask for a quote after having an accurate diagnosis of the system made.
Replacement of LPG injectors, costs
How much does it cost to replace LPG injectors? Going to the mechanism, the replacement of the LPG injectors costs around 600 euros for 4 Landi system components. The cost can change according to the plant and especially according to the required manpower.
The cost is halved if you decide to perform the surgery to replace LPG injectors with DIY . A complete rail with 4 injectors, on Amazon, can be bought with a price between 200 and 300 euros. A rail complete with 4 original Landi injectors, on Amazon, can be bought with 215 euros and free shipping. For all information, please refer to the official Amazon page: Rail complete with 4 original Landi injectors . The same product, at the mechanical workshops, is not found at prices below 280 – 300 euros. Seeing is believing! Prices are slightly higher than for original BRC LPG injectors.
Clean the LPG injectors with an ad hoc cleaner
If the injectors are broken, you will be forced to disassemble to have them replaced. If the injectors are only dirty, you can clean them using one of the many additives available on the market. The dirty injectors cause a decrease in performance of the system and, as a rule, should be cleaned every 30,000 km by entering into circulation a cleaning additive able to dissolve the debris and dirt accumulated in the injectors.
Among the various products on the market, the “Arexons” additives or the complete cleaner from the “Tavola” manufacturer are very valid. In both cases, these are products formulated to clean and protect the entire LPG system, restoring full efficiency to the engine and cleaning the injectors.
In both cases they are high pressure spray cans, equipped with a screwdriver nozzle. The spout is screwed onto the car’s tank cap. It is dispensed until the entire product is finished.
Warning! During dispensing you must not tilt the can otherwise you will not be able to add all the product. Always hold the can parallel to the car by bending the flexible nozzle without tilting the spray container.
These additives have reduced costs. The “Tavola” product is offered on Amazon at a price of 15.42 euros with free shipping costs. For all information I invite you to visit the page: STP Complete cleaner for LPG system . The price of those Arexons changes slightly: a spray bottle of the same size is offered at the price of 16.20 euros with shipping costs included. Also this time we refer you to the official page: Arexons Concentrated LPG Cleaner . The manufacturer promises lubrication and cleaning of the injectors as well as protection for 10,000 km.
