The Guardian of Your Engine's Health: Water Pump for Yuchai Engines
Product Description
In the demanding world of commercial transport, the silent threat
of engine overheating can bring your entire operation to a
standstill. For King Long and Higer buses powered by robust Yuchai engines, the first and most critical line of defense is a high-performance
water pump. Nanjing Dingguan Auto Parts Co., Ltd. proudly
manufactures this essential Water Pump Assembly, a precision-engineered component designed to safeguard your most
valuable asset.
This versatile unit serves as a direct, OEM-standard replacement
for two part numbers: L3000-1307100F and 299023763, making it a flexible and reliable solution for your fleet's
maintenance needs.
At its core, a precision-machined impeller drives maximum coolant
flow, ensuring efficient heat dissipation even under the most
strenuous conditions—from stop-and-go city traffic to long-haul
highway routes. This consistent circulation is vital for
maintaining optimal engine operating temperatures, which directly
translates to improved performance, better fuel economy, and a
significantly longer engine life.
We understand that durability is non-negotiable. That is why this
water pump is constructed with a rugged, corrosion-resistant
housing and equipped with superior, high-grade seals and bearings.
This robust design eliminates the risk of coolant leaks and
premature bearing failure, two of the most common causes of
catastrophic engine damage. By choosing our water pump, you are not
just replacing a part; you are making a proactive investment in
your fleet’s reliability and minimizing the risk of costly,
unscheduled downtime.
Nanjing Dingguan is dedicated to providing powertrain components
that deliver uncompromising quality. Protect your fleet from the
devastating consequences of overheating.

ensure your engines run cool, strong, and reliably.
