Generator set cooling water tank (radiator) - YUCHAI series is a cooling circuit component: it removes engine heat and keeps working temperature inside range.
Overheating rarely starts at the radiator; it starts with air. A dust-blocked core, a fan running backwards or a closed shutter all give the same red needle as a worn pump.

How to verify before ordering
- Match reference, mounting dimensions and connection diameters.
- Check which coolant the component accepts and the cap pressure rating.
- Inspect belt and tensioner together with the pump; doing them later doubles the labour.
- The reference shown on this listing is YCD4.2T100-G21; cross-check it against the one stamped on the removed part.
Frequently asked questions
Can I run plain water instead of coolant?
Not permanently. Water without inhibitor corrodes the block and lowers the boiling point; on a standby set that sits for months, corrosion keeps advancing anyway.
It only overheats under load. Is it the radiator?
It may be insufficient capacity, a dirty fan or a late-opening thermostat. Comparing no-load and on-load temperature tells you which one.
