Multiquip EM808671 Coolant Reservoir

The Multiquip EM808671 Coolant Reservoir is a genuine OEM component designed for the LS300GK hydraulic-driven concrete pump. Sourced directly from Multiquip, this reservoir meets the exact specifications of the original part, ensuring proper cooling system function on your LS300GK. If your existing reservoir is cracked, leaking, or damaged, replacing it with the correct OEM part keeps your cooling circuit operating as intended and protects the engine from heat-related stress during continuous pumping operations.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's exact material and capacity specifications for the coolant system, ensuring proper fluid retention and pressurization without compromise.
• Direct-Fit Replacement — Engineered to mount and connect exactly as the original reservoir on the LS300GK, with matching port locations and mounting points for a clean, tool-friendly installation.
• Confirmed LS300GK Fitment — Verified for use on the Multiquip LS300GK hydraulic-driven concrete pump — no guesswork on compatibility.
• Cooling System Integrity — A properly functioning coolant reservoir maintains consistent fluid levels and allows the system to expand and contract safely, protecting engine components during extended high-load pumping cycles.
• Prevents Overheating Damage — A failing or cracked reservoir can allow coolant loss and air ingestion into the cooling circuit, which can lead to overheating and costly engine or pump damage on the job.

The coolant reservoir serves as the overflow and recovery tank for the engine's cooling system. As the engine heats up and coolant expands, excess fluid is routed into the reservoir; as the system cools, that fluid is drawn back into the radiator to maintain proper fill levels. A damaged or leaking reservoir disrupts this cycle, causing the system to run low on coolant and leaving the engine vulnerable to overheating — a serious risk on a machine running under the sustained load demands of concrete pumping.
