Radiator Flush 250ml – Cooling System Cleaner for compact tractors (Kubota, Yanmar, Iseki)

Description

Before pouring new coolant into a compact tractor, it is wise to thoroughly flush the system first. In older cooling systems, rust, scale, and oil traces build up, significantly reducing heat dissipation — resulting in overheating, especially in hot weather or during heavy work. Radiator Flush dissolves these deposits so the new coolant can perform optimally again.

Why use it on an older compact tractor?

Many Kubotas and Isekis have seen multiple types of coolant over their long lives — sometimes even just tap water. This causes scale buildup and, if there was ever a leaking head gasket, oil residue in the system. A flush before every major coolant change is a small effort that prevents overheating — and overheating is the fastest route to a cracked head gasket in an old tractor engine.

✔️ Removes rust, scale, and oil residues from the entire cooling circuit
✔️ Safe for rubber hoses, plastic reservoirs, and metal parts
✔️ Improves heat dissipation — prevents overheating in summer

How to use it:

1. Shake before use.
2. Add the entire bottle to the cooling system.
3. Run the engine for 10–30 minutes with the heater on, so the product also flows through the heater core.
4. Drain the system completely, rinse with clean water, and fill with new coolant.

Specifications:

• Contents: 250 ml (sufficient for systems up to 10 liters)
• Compatible with all coolant types (G11, G12, G12+, G12++, G13)

Suitable for compact tractors from: Kubota, Yanmar, Iseki, Mitsubishi, Shibaura, Hinomoto, Satoh, and Honda.

Tip: a flush is the perfect time to also check the thermostat and coolant hoses — these often leak unnoticed on older tractors.
