Cooling System Test Cap Set for Chinese Vehicles

A reliable cooling system is vital to prevent engine overheating, coolant leaks, loss of pressure, and costly repairs. For workshops and automotive technicians servicing Chinese vehicles, the Cosda SD-1296C Cooling System Test Cap Set provides a professional, accurate, and efficient diagnostic solution. Specifically designed for leading brands such as Geely, Chery, BYD, and Haval, this radiator pressure test kit delivers a precise fit and secure sealing during coolant pressure testing and vacuum-type coolant refill. By accurately simulating system pressure, mechanics can quickly detect faulty radiator caps, hairline leaks, and hidden cooling issues before they escalate into engine damage. In addition, the vacuum refill function allows for easy coolant replacement without air pockets, ensuring proper circulation and preventing hot spots.

With the rapid expansion of hybrid and electric vehicles, cooling system maintenance is just as critical as in traditional fuel-powered engines. Modern EVs and plug-in hybrids use dedicated cooling loops for the battery, inverter, and power electronics, and leaks or blockages in these circuits can compromise safety and performance. For example, on BYD’s popular Atto 3, battery temperature may rise significantly during fast charging or high-power driving, while thermal management systems sometimes react too slowly. Without proper diagnostic tools, these conditions can accelerate wear and even lead to component failures. Currently, standard radiator cap testers do not cover Chinese vehicle applications, but Cosda fills this critical gap with the SD-1296C test cap set, bringing a dedicated solution to the market.

This cooling system diagnostic tool set is designed with professional mechanics, fleet workshops, and service centers in mind, where precision and reliability are essential. Common questions such as “Which vehicle models are compatible?” are easily answered with the comprehensive application chart included in the instruction manual, listing all supported makes and their corresponding test caps. Exclusively developed by Cosda, this innovative set demonstrates our commitment to high-quality automotive tools and B2B solutions. For distributors and workshop suppliers, we also offer private branding / OEM services, helping you lead the market with exclusive, cutting-edge products. With the Cosda SD-1296C Cooling System Test Cap Set, you’re not just buying a tool—you’re investing in accuracy, durability, and a competitive advantage.
