二、精准适配机型
压路机系列
BW220D-40（主力适配机型）、BW211D-40、BW219D-4、BW216D-4、BW213-3、BW203AD-4、BW120AD-4 第四代水冷压路机
摊铺机系列
BF800C 沥青摊铺机
三、产品核心优势
- 原装开模一体成型：安装孔、进出水口、传感器位 1:1 复刻原厂，无需改装、不改动管路
- 耐工地恶劣工况：耐高温、耐震动、耐酸碱防冻液，长期暴晒、重载作业不易变形渗漏
- 可视化液位管：透明刻度管实时查看冷却液余量，缺水提前预警，避免发动机高温拉缸
- 配套泄压水箱盖：稳定平衡冷却系统内部压力，杜绝高温水路鼓包、水管爆漏
- 自带传感器安装位：支持原车缺水报警功能，设备故障实时提醒，降低大修成本
四、安装替换提示
- 区分老款配件：宝马格 D-3 系列水箱件号 58190216，尺寸孔位不通用，不可混用
- 配套采购建议：同步备货水箱盖、水管卡箍、密封圈，一次性完成整套更换
- 安装流程：排空旧防冻液→清洗管路水垢→对位固定水箱→连接液位传感器→加注新防冻液排空气
五、适用场景
道路施工、市政摊铺、基建压实、工地长期连续作业压路机、摊铺机冷却系统维修替换；修理厂、配件批发商、租赁公司批量备货首选配件。
六、售后服务
现货库存，当天可发货；出厂水压密封性检测，质保支持；批量采购可享阶梯优惠，支持工程机械全车配件一站式配齐。

06550084 Coolant Expansion Tank for BOMAG Construction Machine
Product Overview
Part No.06550084 coolant expansion tank (auxiliary water tank / compensation tank) is OEM matching spare part for BOMAG 4th generation road rollers and asphalt pavers. It perfectly replaces original damaged tank with identical mounting holes, pipe connectors and sensor base, plug-and-play installation without any cutting or refitting. Effectively solve problems like tank cracking, coolant leakage, high temperature pressure failure, unclear liquid level observation, prevent engine overheat damage and reduce machine downtime cost.
Basic Specifications
- OEM Part Number: 06550084
- Cross Reference Number: 58190395, 06550121
- Product Name: Engine Coolant Reservoir / Expansion Tank / Auxiliary Water Tank
- Material: Thickened modified engineering plastic, anti-aging, anti-freezing liquid corrosion, shock-resistant
- Standard Accessories: Pressure relief cap, transparent sight level tube, liquid level sensor port, original mounting bracket
- Applicable Brand: BOMAG
Compatible Machine Models
Road Roller
BW220D-40, BW211D-40, BW219D-4, BW216D-4, BW213-3, BW203AD-4, BW120AD-4
Asphalt Paver
BF800C
Key Advantages
- 1:1 Original Mold: All installation holes, inlet/outlet ports, sensor position same as original, direct replacement.
- Heavy-duty Construction Site Durability: Resist high temperature, strong vibration and chemical coolant, no deformation or leakage under long-time heavy load work.
- Visible Level Sight Tube: Real-time coolant volume check, remind operator low liquid level in advance to avoid engine overheating and cylinder pulling.
- Pressure Relief Cap: Balance internal cooling system pressure, avoid pipe burst and tank bulging under high working temperature.
- Reserved Sensor Port: Compatible with original low coolant alarm system, timely fault warning to save huge engine maintenance cost.
Installation Notes
- Do not mix with old D-3 series tank (PN 58190216), different size and hole position, non-interchangeable.
- Matching spare parts recommendation: pressure cap, hose clamps, sealing gaskets available together for one-stop replacement.
- Installation Steps: Drain old coolant → Clean pipeline scale → Fix expansion tank → Connect level sensor → Fill new coolant and exhaust air.
