Multiquip 12851006 Radiator Cap F3M1008F LT-12D

The Multiquip 12851006 is a genuine OEM Radiator Cap F3M1008F LT-12D designed for LT12D light tower and F3M1008F engine applications. As a direct OEM replacement, this cap is manufactured to the exact pressure rating and sealing specification required by the original cooling system — no guesswork, no improvised substitutes. Sourced directly through Multiquip's authorized parts network, 12851006 ensures the cooling system maintains correct operating pressure across demanding jobsite conditions. Confirm your model against the LT12D and F3M1008F fitment data before ordering to ensure an exact match.

Key Features

• Correct Pressure Rating — Manufactured to the exact OEM pressure specification for the LT12D cooling system, ensuring the radiator cap seats, seals, and releases at the designed threshold.
• Genuine OEM Part — Supplied as an authentic Multiquip component, not an approximation — same cap that ships on new equipment from the factory.
• Direct Drop-In Replacement — Engineered to thread directly onto the radiator filler neck of compatible equipment with no modification to the cap, neck, or overflow system.
• Confirmed Fitment — Verified for LT12D light tower and F3M1008F engine configurations; always cross-reference your model code before ordering.
• Coolant System Integrity — A correctly rated cap keeps the cooling system pressurized to raise the boiling point of coolant, protecting the engine from overheating during extended generator and light tower operation.

The radiator cap is a pressure-regulating valve that seals the cooling system and maintains the internal pressure needed to raise coolant's effective boiling point. When the system reaches operating pressure, the cap holds it steady; if pressure exceeds the rated limit, the cap vents coolant safely to the overflow reservoir. A worn, cracked, or incorrectly rated cap causes coolant loss, unstable pressure, and accelerated overheating — problems that can quickly escalate to engine damage on a continuously running light tower like the LT12D.
