DPTOOL Multiair Variable Valve Actuator Removal Tool 10259B – Fiat/Alfa/Chrysler 1.4L–2.4L Multiair, Spring Compressor

DPTOOL 10259B is a dedicated variable valve actuator assembly removal tool and spring compressor made to safely remove and tension Uniair and Multiair module spring plates on compatible Fiat, Alfa Romeo and Chrysler engines.

When you need to service the Multiair/Uniair variable valve system on Fiat, Alfa Romeo or Chrysler vehicles, the right specialist tool prevents damage and shortens repair time. The DPTOOL 10259B is engineered to fit common Multiair engine architectures — including the Fiat 1.4L 16V Multiair, 2.0L, and 2.4L variants — and matches several OEM reference numbers. It streamlines removal of the variable valve actuator assembly and provides controlled spring plate tensioning so technicians can work faster and with greater confidence.

How does this tool protect the Multiair actuator during removal?

The 10259B applies even, controlled pressure to depress and hold the actuator spring plates, eliminating the risk of sudden release or component damage. Its contact points and geometry are designed to match the actuator assembly, reducing slippage and misalignment while you work.

• Precision fit for Uniair/Multiair actuator profiles
• Stabilizes spring plates to prevent sudden decompression
• Reduces risk of bending or scoring aluminum actuator housings
• Speeds up safe removal and reinstallation

Which engines and model years will this tool work with?

DPTOOL lists compatibility with several Fiat/Chrysler Multiair engine codes and a broad range of model years. It supports 1.4L Multiair 16V, 2.0L and 2.4L Multiair engines across many vehicle series from approximately 2012 through 2019.

• Compatible engine codes: 955 A6.000, 955 A2.000, 198 A7.000, 955 A7.000, 955 A8.000, 940 A2.000
• Suitable for many model-year designations from 2012–2019
• Fits Fiat, Alfa Romeo and Chrysler Multiair platforms
• Works with OEM-equivalent numbers 10259B, 2000034500, 10324, 10409

What are the practical benefits for a mechanic or DIYer?

This specialized compressor reduces trial-and-error handling and lowers the chance of collateral damage to valves, actuators or cylinder heads. Because it’s purpose-built, the tool helps shops maintain throughput while preserving part integrity during disassembly and reassembly.

• Minimizes downtime through predictable, repeatable operation
• Prevents costly replacement of damaged actuators or housings
• Compact design stores easily in a tool chest or service cart
• OEM-equivalent compatibility simplifies parts sourcing

Is this tool easy to use and safe for repeated shop use?

Yes — the 10259B is built for repeated use with materials and dimensions suited to professional environments. Its form factor and engagement surfaces are optimized to grip the actuator assembly securely, while controlled compression reduces manual strain and unexpected movements.

• Durable construction for frequent workshop cycles
• Designed to interface cleanly with Multiair module spring plates
• Reduces manual force required compared with improvised methods
• Helps technicians maintain correct alignment during service

Who is this for? If you service Fiat, Alfa Romeo or Chrysler engines that use the Multiair/Uniair variable valve system — whether you are a professional technician, an independent shop, or an experienced DIY mechanic — the DPTOOL 10259B is a targeted addition to your toolkit. It is especially useful when replacing or inspecting actuator modules on 1.4L Multiair 16V, 2.0L and 2.4L engines and when you want to reduce the risk of damage while improving repair speed and consistency.
