Hydraulic Lines – Alfa Romeo 8C Q-Select
This is a complete set of brand-new hydraulic lines for the Alfa Romeo 8C Q-Select transmission. Including lines for EV1, EV2, EV3, EV4, EV5 and EVF.
All lines are made in Germany and come with a black protection coating.
Pentosin CHF 11S
Pentosin CHF 11S is a synthetic high performance hydraulic fluid for life-time application in modern vehicle aggregates. Pentosin CHF 11S is especially designed for hydraulics in the automotive industry with the highest technical requirements such as in: power steering, level control, shock absorber, hydro-pneumatic suspension, stability and traction control, hydraulics for convertible tops, central lock systems, etc.
It is suitable for all extreme conditions and guarantees full performance from -40 Degree Celsius to over 130 Degree Celsius system temperature.
Pentosin CHF 11S meets DIN 51 524T3 and ISO 7308 specification standards.
PPV Solenoid Valve – Alfa Romeo 8C Q-Select
The valve block / power unit of the Alfa Romeo Q-Select system contains 6 solenoid valves.
- EVF (QPV) – clutch engagement
- EV1 (PPV) – gear engagement
- EV2 (PPV) – gear engagement
- EV3 (QPV) – gear selection
- EV4 (QPV) – gear selection
- EV5 (QPV) – gear selection
Photo for demonstration purpose only. The valve may come without sticker label. Depending from model and year of construction the numbers on the sticker label may vary. In case you are not sure if the part fits your car, please contact us before you buy.
Pressure Accumulator – Alfa Romeo 8C Q-Select
The pressure accumulator is responsible to store the pressure of the hydraulic system for later access by the actuators. This piston type accumulator has two cells: one cell storing the hydraulic fluid and one cell containing a Nitrogen gas filling which creates the counterpressure. Both cells are separated by a moving piston. Typical symptoms of a faulty pressure accumulator are frequent and short pump cycles. If there is no more preload pressure left in the accumulator, the pump runs every few seconds, which ultimately leads to a consequential damage of the pump motor. Along with the pump motor, a faulty pressure accumulator is one of the most common causes of pressure build-up issues and is one of the few wear parts in the system that should be regularly checked and replaced if necessary.
We offer a brand-new replacement accumulator.
Pressure Relief Valve – Alfa Romeo 8C Q-Select
The pressure relief valve is responsible to prevent damage to other components due to excess pressure in the hydraulic system. A defective valve would cause pressure loss and frequent pump cycles (similar symptoms as a worn pressure accumulator).
Pressure Sensor – Alfa Romeo 8C Q-Select
The pressure sensor is responsible to detect the hydraulic pressure in the accumulator of the Q-Select system. This is an original and brandnew spare part.
Pump Motor – Alfa Romeo 8C Q-Select
The pump motor drives the gear pump, which generates the pressure for the Q-Select transmission. Both parts together form the hydraulic pump. Without hydraulic pressure, the transmission cannot perform any action – neither change gears, nor operate the clutch. Therefore, the hydraulic pump is the most important component in the system.
In most cases, it is sufficient to replace only the electric motor, as this is a wearing part. The gear pump fails only very rarely. Another advantage is that when only the pump motor is changed, the hydraulic system does not need to be bled afterwards, unless it has been opened.
We sell an original, brand new Magneti Marelli spare part – the same part you would get from Alfa Romeo.
Pump Relay – Alfa Romeo 8C Q-Select
The pump relay is responsible to switch on / off the hydraulic pump. A broken relay causes the pump to fail priming. Without hydraulic pressure, the system cannot engage the gears or clutch.
QPV Solenoid Valve – Alfa Romeo 8C Q-Select
The valve block / power unit of the Alfa Romeo Q-Select system contains 6 solenoid valves.
- EVF (QPV) – clutch engagement
- EV1 (PPV) – gear engagement
- EV2 (PPV) – gear engagement
- EV3 (QPV) – gear selection
- EV4 (QPV) – gear selection
- EV5 (QPV) – gear selection
