The genuine XCMG 380901184 Heated Water Pipe is an OEM engine coolant circulation hose designed for motor grader cab heater and windshield defroster systems. This 380901184 heated water pipe carries hot engine coolant from the cylinder head to the cab heater core, providing warmth for operator comfort and clear visibility in cold weather. Manufactured from EPDM synthetic rubber with textile reinforcement and a heat‑resistant cover, the XCMG hose withstands continuous temperatures up to 120°C and intermittent peaks of 150°C. The pipe is pre‑formed to precise factory bends for XCMG GR135, GR165, GR180, GR215, GR260, GR300, and GR350 motor graders.
The heated water pipe is a critical component of the cabin climate control system. A cracked, swollen, or leaking hose can cause coolant loss, engine overheating, and loss of cab heat, making winter operation difficult or impossible. Replacing a worn hose with genuine XCMG 380901184 restores proper coolant flow, ensures reliable heater performance, and prevents engine damage from coolant leaks.
This pipe is also used in auxiliary heater circuits and engine pre‑heating systems. XCMG 380901184 guarantees OE dimensions, correct bend angles, and long‑term resistance to coolant chemicals and ozone cracking.

The 380901184 heated water pipe transfers hot engine coolant to the cab heater core, providing warm air for operator comfort and windshield defrosting.
In cold climates, a failed heater hose makes operation miserable and reduces safety due to fogged windows. The pipe also returns cooled coolant to the engine, completing the heater circuit.
A leak in this hose can cause low coolant level, engine overheating, and potential head gasket failure. Replacing a damaged pipe with genuine XCMG 380901184 restores heater function and cooling system integrity.
Each 380901184 hose is extruded from premium EPDM rubber, which resists degradation from antifreeze, heat, and ozone. The inner tube is smooth to minimize flow restriction.
A textile braid reinforcement prevents expansion under pressure while maintaining flexibility. The cover is engineered to resist cracking from under‑hood chemicals and UV exposure.
The hose is formed to the exact OEM shape using a mandrel, then post‑cured to set the bends. XCMG tests each batch for burst pressure, heat aging, and coolant compatibility.
To replace a leaking heater hose, drain the coolant to a level below the heater connections. Use hose clamp pliers to remove spring clamps or screw clamps.
Twist the old hose to break corrosion seal, then pull it off the fittings. Clean any residue from the heater core and engine nipples. Install the new 380901184 hose, pushing it fully onto both barbs.
Secure with new constant‑tension spring clamps. Refill coolant, warm up the engine, and check for leaks. Always replace both heater hoses (supply and return) as a set for even aging.
Visible cracks or bulging on the hose, soft or spongy feel when squeezed, coolant odor inside the cab, fogged windows that won’t clear, and low coolant level with no external engine leaks.
Also, if the hose shows hard, brittle sections or has been in service for over 5 years, replace it preventively to avoid sudden failure.
Inspect heater hoses every 500 operating hours or during coolant changes. Squeeze the hose – if it feels crunchy or cracks appear, replace immediately.
Typical service life is 4,000‑5,000 hours or 5 years, whichever comes first. EPDM rubber ages even when the machine is parked due to ozone and temperature cycles.
When replacing a heater hose, always use new spring clamps. Old clamps lose tension and may leak. Keep a spare 380901184 hose in your parts inventory for winter‑season readiness.
Genuine XCMG 380901184 heated water pipes carry a 12‑month warranty. Regional warehouses in Houston, Rotterdam, Dubai, and Shanghai maintain deep stock for rapid dispatch.
Standard air freight delivers within 3‑7 business days worldwide. Emergency 24‑48 hour shipping available for cold‑weather breakdowns. Bulk orders (10+ hoses) receive volume discounts and sea freight options.
Aftermarket heater hoses often use inferior rubber that fails quickly or have incorrect pre‑formed bends that kink and restrict flow. Genuine XCMG 380901184 ensures perfect fit, proper material, and long‑term reliability.
Don’t let a burst heater hose leave your grader cold and stranded. Keep a spare 380901184 pipe in your cab for on‑site replacement. Genuine XCMG quality means reliable heat and peace of mind.
Order the genuine XCMG 380901184 Heated Water Pipe today and maintain operator comfort, clear visibility, and engine cooling integrity for thousands of operating hours.
