Key Features

• OEM-Grade Sealing Material — Manufactured to the original material and dimensional spec, ensuring a proper compression seal around the radiator base without gaps or distortion.
• Direct Drop-In Replacement — Engineered to align with the existing mounting points on QST30 series equipment, allowing straightforward installation without modification.
• Confirmed QST30 Fitment — Verified for compatibility with QST30 machines, eliminating guesswork when sourcing cooling system components.
• Protects Cooling System Integrity — A properly seated bottom flashing directs airflow through the radiator core and prevents bypass, maintaining effective engine cooling under load.
• Genuine Multiquip OEM Part — Carries the full backing of Multiquip's parts program, ensuring the component meets the same standards as the original equipment build.

The radiator bottom flashing is a formed sealing panel that fits along the lower edge of the radiator assembly, bridging the gap between the radiator and the surrounding shroud or frame structure. Its role is to channel airflow through the radiator core rather than allowing it to escape around the sides or bottom, which is critical for consistent engine temperature management. When this flashing becomes cracked, deformed, or missing, cooling efficiency drops and the engine is at greater risk of running hot under sustained load.
