The Multiquip 42926-01 is a genuine OEM Radiator Cap designed for Whiteman hydrostatic ride-on power trowels, including the HTXG6DF, HTX6H, and STX6H. As a direct Multiquip OEM part, the 42926-01 is manufactured to the exact pressure rating and dimensional spec required by the cooling system on these machines. Sourcing a genuine OEM cap means the seal, pressure valve, and cap body all meet the original design tolerances — no guesswork on fitment or pressure performance. If your ride-on trowel is running hot, losing coolant, or showing a worn or cracked cap, the 42926-01 is the correct direct replacement.
Key Features
- OEM Pressure Rating Match — Engineered to the exact pressure specification of the original cooling system, ensuring proper coolant pressurization and system integrity.
- Direct-Fit Replacement — Designed to seat and seal on the factory radiator neck of HTXG6DF, HTX6H, and STX6H trowels without modification.
- Confirmed Fitment — Verified for Whiteman hydrostatic ride-on trowels including the HTXG6DF, HTX6H, and STX6H series.
- Cooling System Protection — A correctly rated radiator cap maintains the pressure threshold that raises the coolant boiling point, keeping the engine operating in its safe temperature range during heavy finishing work.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, so the part number, dimensions, and pressure valve function match the original component exactly.
A radiator cap does more than simply close the cooling system — it functions as a pressure valve that controls the operating pressure of the coolant circuit. By maintaining a calibrated pressure level, it raises the boiling point of the coolant and allows the overflow system to return coolant back into the radiator as the engine cools. A cap that has lost its seal or is rated at the wrong pressure can cause coolant loss, overheating, and accelerated engine wear, particularly under the sustained load demands of a ride-on trowel finishing a large concrete pour.
