Basic Product Parameters
\nPart Number: WG9925530003 Product Name:Cooling System Expansion Water TankAssembly, Tank, Water Supplement Bottle)Applicable Models: Sinotruk Howo A7, HowoT7H full series tractors, truck trucks, dumpengineering vehicles Material: high toughnessand low temperature resistance PPtransparent plastic Standard accessories:pressure relief tank cover, inlet and outletwater pipe interface Optional version: basicmodel \/ with level water sensor assembly<\/p>\n
Installation and Functions
\n1. Freeze storage compensation: Hold excess
\nantifreeze during thermal expansion and contraction,automatically compensate for the cooling systemliquid level, and avoid high water shortages.
\n2. Pressure relief and pressure regulation protection: It isequipped with a built-in pressure cover to balance pipelinepressure, preventing water pipe bulging and tank cracking;
\n3. Liquid level pre-monitoring (sensor type):Water autonomous cab alarm, timely coolantreplenishment, and engine cylinder protectionbody;
\n4. Exhaust gas collects pipe air, reduces air resistance,improves heat dissipation efficiency, and prevents hightemperatures from being easily exposed to long-distance heavyoads.
\nVentajas principales del producto
\n1. Thick cracked material
\nIntegral injection molding thickened transparent PPmaterial, resistant to low temperatures as minus 40\u00b0Cresistant to high temperatures of 120\u00b0C, remains brittleand crack-free after prolonged antifreeze immersion,and completely prevents leakage.
\nFactory-level precision hole positior
\nThe original vehicle mold opening, fixed bracket, waterpipe interface, and installation holes are fully
\nmatched. They require sanding and modification, andthe original vehicle’s old water tank can be directly
\nreplaced.
\n3. Sealed leak-proof components
\nThe aging-resistant rubber pressure cover is
\nequipped with a stable pressure relief valve,
\nensuring no water seepage during bumping orclimbing conditions; the interface is free of burrs,and the tubing is tightly sealed.
\n. Two specifications are available.
\nBasic maintenance configuration model, original
\nfactory assembly model with level sensor, meeting thediverse needs of fleet maintenance and assembly.<\/p>\n
[Common Faults & Replacement Tips] FaultPhenomena requiring a water tank
\nreplacement
\n1. Cracks outside the box, and antifreeze
\nleakage from the bottom;
\n2. Plastics become white and brittle due toaging, and suffer from high water
\nshortages;
\n3. The sensor level alarm fails, making it
\nimpossible to monitor water volume;
\n4. Pressure cover failure, frequent leakage,
\nand abnormal pipeline pressure.
\nInstallation Tips
\nWhen replacing, simultaneously inspect the water pipeclamps and sealing rings; after adding antifreeze, drainthe air from the pipeline to avoid air blockage and hightemperatures; in northern winters, it is recommended touse long-lasting antifreeze coolant to slow plastic aging<\/p>","protected":false},"excerpt":{"rendered":"
