The Multiquip 3303104 is a genuine OEM Heater Block designed for DCA85SSK and SA6D125 ultra-silent generator sets. As a direct OEM replacement, this part is sourced and validated to the same specifications as the original component installed at the factory, ensuring correct fitment and thermal performance on DCA85SSK equipment equipped with the SA6D125 engine. DHS Equipment stocks this Multiquip part so you can get your generator back online without guesswork or modification. Trust the OEM part number 3303104 when ordering to confirm you are receiving the correct block for your machine.
Key Features
- OEM Thermal Specification Match — Engineered to the exact heat-transfer and material tolerances required by the SA6D125 engine block, preventing coolant heat loss or cold-start failures.
- Drop-In Fitment for DCA85SSK — Mounts to the existing port configuration on DCA85SSK generator sets, with no reworking of lines or brackets required at installation.
- Genuine Multiquip OEM Part — Sourced directly through the Multiquip supply chain; part 3303104 carries the same quality standard as the component originally built into the machine.
- Protects Engine Start Performance — A correctly functioning heater block maintains optimal coolant temperature at startup, protecting the SA6D125 engine from cold-start wear and hard-start conditions.
- Fuel System and Engine Safety Relevance — Proper block heater function is critical in cold-weather deployments where unassisted cold starts can stress fuel injection components and reduce engine service life.
A heater block, also known as a block heater or engine pre-heater, warms the engine coolant before startup — particularly important in cold ambient conditions. On large diesel generator sets like the DCA85SSK with the SA6D125 engine, pre-heating the coolant reduces the viscosity load on the engine at startup, allowing oil to circulate more freely and fuel to combust more efficiently from the first crank. When the heater block fails or develops a leak, cold starts become harder on internal engine components, and in standby or emergency power applications where instant readiness is critical, a faulty block heater can compromise the reliability of the entire unit.
