DPTOOL Multiair Spring Compressor & Variable Valve Actuator Removal Tool 10259B — Fits Fiat/Alfa/Chrysler 1.4–2.4L, OEM‑equivalent

The DPTOOL 10259B is a dedicated variable valve actuator removal and spring-compression tool engineered to safely disengage Multiair/Uniair actuator assemblies on select Fiat, Alfa Romeo and Chrysler 1.4L–2.4L engines.

This specialist service tool lets technicians and DIY mechanics remove and reinstall the Multiair/Uniair variable valve actuator and tension the module’s spring plates without damaging the actuator, housing or surrounding components. Designed to match OEM fitment numbers (10259B, 2000034500, 10324, 10409), it supports a range of FCA engine codes and model years where Multiair technology is used.

Which engines and models does this DPTOOL fit?

The DPTOOL 10259B is built for Fiat Chrysler applications that use Uniair/Multiair modules. It covers 1.4L Multiair 16V engines and larger 2.0L and 2.4L Multiair variants found across Fiat, Alfa Romeo and Chrysler lineups from mid‑2010s model years.

• Compatible engine codes: 955 A6.000, 955 A2.000, 198 A7.000, 955 A7.000, 955 A8.000, 940 A2.000
• Applicable years: 2012–2019 variants listed for model codes FF, PF, BF, FB, UF, VM and others
• OEM-equivalent numbers: 10259B, 2000034500, 10324, 10409

How does the tool protect the actuator and springs during removal?

DPTOOL’s compressor precisely tensions the module’s spring plates so you can release and reinstall the variable valve actuator without bending tabs or distorting the actuator housing. Its contact points are sized to fit the Multiair assembly and distribute load evenly, reducing risk of part damage.

• Controls spring tension to prevent sudden release
• Even load distribution minimizes deformation of spring plates
• Reduced chance of actuator housing or seal damage during service

What will I need to use this tool effectively?

Using the DPTOOL 10259B requires basic mechanical experience and standard workshop tools. It’s designed to work alongside typical hand tools and a safe work procedure for removing the valve cover and accessing the Multiair module.

• Basic hand tools and torque wrenches for surrounding components
• Clean workspace and vehicle on a stable lift or jack stands
• Familiarity with Multiair module removal steps and safety precautions

Can this tool replace OEM service tools and where does it excel?

DPTOOL 10259B is manufactured to align with OEM-equivalent part numbers and provides a cost-effective alternative for garages and owners servicing Multiair actuators. It excels in repeatability and protects expensive valve components when used correctly.

• OEM-equivalent design for proper fit and function
• Durable construction suitable for professional use
• Compact footprint for tight engine bay access

Who is this for: Professional mechanics, independent repair shops and experienced DIYers who service Fiat, Alfa Romeo or Chrysler vehicles equipped with Multiair/Uniair variable valve modules. If you need to remove, tension or reinstall the actuator assembly without risking damage to the spring plates or module housing, this tool was made for that task.
