Tongyi Zhileng Quanqingtong All‑Compatible All‑Organic Coolant

Product Overview

Tongyi Zhileng Quanqingtong is a universal all‑organic OAT coolant. Adopting exclusive corrosion‑inhibiting formulation, it realizes three‑fold universality: color‑free compatibility, freezing‑point‑free compatibility, vehicle‑model‑free compatibility. It is mixable with conventional ethylene‑glycol coolants. Delivers six‑fold protection including anti‑freeze, anti‑boil, anti‑corrosion, anti‑rust, anti‑scale and anti‑bacteria. Effectively protects multi‑metal components such as aluminium, cast iron, copper and solder inside cooling circuits, and shows good material compatibility with rubber & plastic sealing parts. As one of the drafters for China national coolant standard, this product meets multiple domestic & international industry and OEM specifications.

Core Performance Features

  • Three‑fold universal compatibility: No restriction on original coolant color, existing freezing‑point grade or vehicle model; supports topping‑up and mixed replacement for ethylene‑glycol‑based cooling systems.
  • Six‑fold comprehensive protection: Anti‑freeze, anti‑boil, anti‑corrosion, anti‑rust, anti‑scale, anti‑bacteria; long‑term stable protection for the whole cooling system.
  • Multi‑material compatibility: Provides reliable anti‑corrosion performance for aluminium alloy, cast iron, copper, solder and other metals; friendly to hoses, gaskets and plastic components.
  • High extreme‑temperature stability: -46 ℃ freezing‑point performance for severe cold‑region use; 131 ℃ pressurized boiling‑point prevents engine over‑boil under high‑load working conditions.
  • Long service interval: Long‑drain formulation for extended service life, lowering vehicle maintenance frequency and operating cost.
