The Multiquip 42559 is a genuine OEM HATZ 4H50TIC Charge Air Cooler designed for HTX6H and STX6H hydrostatic ride-on power trowels. As a direct Multiquip OEM replacement, this charge air cooler is manufactured to the same specifications as the original unit installed at the factory, ensuring a correct, trouble-free fit in compatible machines. Verify your model code before ordering — this cooler is confirmed for HTX6H and STX6H trowel applications powered by the HATZ 4H50TIC engine. DHS Equipment stocks genuine Multiquip parts so you can get your machine back in service without compromise.
Key Features
- Genuine OEM Cooling Specification — Manufactured to the exact thermal transfer and pressure ratings required by the HATZ 4H50TIC engine, not a generalized approximation.
- Direct Bolt-On Replacement — Matches the original mounting points, inlet/outlet ports, and core dimensions of the factory-installed unit for a straightforward swap.
- Confirmed Fitment for HTX6H and STX6H — Engineered specifically for Multiquip HTX6H and STX6H hydrostatic ride-on trowels equipped with the HATZ 4H50TIC diesel engine.
- Protects Engine Output and Longevity — A properly functioning charge air cooler keeps intake air temperatures in check, allowing the engine to maintain rated power output during extended troweling operations.
- Prevents Thermal Stress on Engine Components — A failing or blocked charge air cooler raises combustion temperatures, accelerating wear on pistons, rings, and valves — replacing it promptly protects the entire drivetrain.
A charge air cooler — also called an intercooler — sits between the turbocharger and the engine's intake manifold on turbocharged diesel engines like the HATZ 4H50TIC. Its job is to cool the compressed air coming out of the turbocharger before it enters the combustion chamber; cooler air is denser, which means more oxygen per charge and more efficient combustion. When the charge air cooler is cracked, leaking, or internally blocked, intake air temperatures rise, power output drops, exhaust temperatures climb, and long-term engine damage becomes a real risk. Replacing a worn unit with a genuine Multiquip 42559 restores correct boost pressure, intake temperature, and engine performance on your HTX6H or STX6H trowel.
