Multiquip 49099000 Rad Cap MQ600HTP

The Multiquip 49099000 Rad Cap MQ600HTP is a genuine OEM radiator cap designed for the MQ600HTP trash pump. As a factory-sourced component, it meets the exact pressure specification required by the MQ600HTP cooling system, ensuring the cap seats and seals correctly every time. Sourced direct from Multiquip, this is the same part installed at the factory — no guesswork on compatibility. If you're servicing an MQ600HTP and need a cap you can trust, 49099000 is the correct replacement.

Key Features

• OEM Pressure Rating — Built to the exact pressure relief specification for the MQ600HTP cooling system, maintaining proper coolant pressure under load.
• Secure Sealing Surface — Engineered to seat flush against the MQ600HTP radiator filler neck, delivering a consistent, leak-free seal with every installation.
• Direct MQ600HTP Fitment — Confirmed fitment for the MQ600HTP trash pump; no adapters or modifications to the cooling system needed.
• Protects Cooling System Integrity — A worn or failed radiator cap allows coolant to escape and air to enter, leading to overheating and potential engine damage during pump operation.
• Genuine Multiquip OEM Part — Part 49099000 is sourced directly through Multiquip's authorized parts program, giving you confidence in quality and long-term durability.

A radiator cap does more than simply close off the coolant reservoir — it actively controls the pressure within the cooling system. By maintaining a set pressure level, it raises the boiling point of the coolant, allowing the engine to run at optimal temperature without losing fluid. On a high-output unit like the MQ600HTP trash pump, where sustained operation under demanding conditions is the norm, a faulty cap can cause coolant loss, overheating, and accelerated engine wear. Replacing a degraded cap with the correct OEM part restores proper system pressure and keeps the engine running within its designed temperature range.
