Introduction8
Despite the name ValveCare-di suggests that the system can only be installed with VSI-DI, it can
certainly also be combined with VSI-2.0 MPI and Direct LiquiMax Gen3.
The ValveCare-DI system is a full electronic sequential regulated additive dosing system suitable for
direct injected and port gas injected engines. It can be applied to VSI-2.0 (MPI), VSI-2.0 DI, VSI-3 DI
and Direct LiquiMax. In combination with the highly effective Prins additive, the system will
contribute to a cleaner combustion chamber and improved durability of valves and valve-seats
against excessive wear.
The Prins ValveCare-DI dosing module contains special software to communicate with the Prins
AFC.
Highlights8.1
Ideal distribution by electronic regulated sequential feed into the combustion chamber
Suitable for both turbo and non-turbo engines
Easily refillable additive-reservoir
Self-diagnosis on inbuilt components
Only additive consumption during running on LPG

General operation10
The ValveCare-DI system only injects additive during running on LPG. The electronically operated
dosing unit sequentially divides the additive in equal quantities, depending on the LPG
consumption (higher LPG consumption -> more additives). The additive is injected per cilinder. It is
transported via a PTFE hose, connected to the LPG injector hose, or directly into the inlet manifold
with separate nozzles.
The additive reservoir can be fitted separately from the dosing unit for an easier and more user
friendly installation.
The additive is highly effective and protects valves, valve seats, injectors and the
combustion chambers against excessively pollution and wear.
The consumption of the additive has a ratio of 1 litre additive on 1000 litre LPG.
After 100l gas the injected additive should be 100ml.
In case the additive reservoir is empty, the Prins switch will indicate a blue exclamation mark
(blinking), and the engine can run another 4 hours on LPG.
After 4 hours the engine only runs on petrol and the exclamation mark and will be active. Filling up
the additive-reservoir will make driving on LPG possible again.

ValveCare-DI additive level is low -> 4 hours LPG mode
left.

Caution!
Do not use or mix other additive with the original Blue Prins ValveCare-DI
additive. Use of other additive can harm the system and warranty will
expire directly
Before assembling or working on the ValveCare dosing system, all safety
regulations must be observed.

Hardware11
Dosing module11.1
Fit the dosing unit in a proper location, taking in mind that on both sides of
the dosing unit, additive feed lines come out. These feed lines have to be
connected to the gas supply lines between injector rail and manifold.
Part numbers
099/040010 4 cylinder divider
099/040011 6 cylinder divider
Wiring loom11.2
The wiring loom has 3 super seal connectors for connecting the dosing unit and
additive reservoir. The other ends should be connected (soldered) to the Prins
wiring loom/car wiring, according to the electrical diagram.
Add the extra 1K8 resistor for the VSI-2.0 MPI systems, like described in the wiring
diagram.

Nipples and hose connections11.8
Variants11.8.1
Choose the correct type of mounting kit, depending on the used gas feed line between the gas
injectors and the manifold.
5mm and 6mm rubber gas and PTFE feed hose
Cut the 5mm LPG hose at a suitable position.
Insert the additive T-piece and secure it using
suitable clip collars.
Connect the additive hose into the push-fit
connector of the correct output on the module.
6mm nylon gas feed hose
Cut the nylon hose.
Insert the additive T-piece and secure it using
suitable clip collars.
Connect the additive hose into the push-fit
connector of the correct output on the module.
Direct manifold m5
Direct LiquiMax Gen3
Direct LiquiMax applications
Drill a 4.2 mm hole into the manifold. Tap an
M5 thread into this hole. Screw in the additive
jet, using thread sealant paste. The length of
the thread can be sawn down if required. The
end of the jet should not touch the wall inside
the manifold.
Remark!
Cut the PTFE (white) and Nylon (black) hose whit a sharp knife of hose
cutter in a perfect 90 degree angle. This is Necessary for a proper fitting in
the coupling and prevents any damages to the internal coupling seals.

3 –5 cilinder engine11.8.2
Remark!
In case of a 3 or 5 cylinder engine, outlet 4 and 6 should not be used. In the
ValveCare-DI software, the right settings should be made. Prins advises to
use a small piece of 4mm PA hose, melted together, to plug of the unused
outlet. This prevents dirt entering the unused outlet plug.
Melt a small piece of the PA hose together
Insert the blocked hose in outlet 4 or 6
