Before topping up oil or coolant in your Iseki TU165, it's helpful to know exactly which fluid goes where and how much you need. In this article, we've listed all the capacities for you, including an important point about the hydraulic system that you shouldn't miss.
Suitable for the entire series: Iseki Landhope TU145, TU155, TU165 and TU175 (2WD and 4WD versions).
The capacities below apply to all models in the series (TU145, TU155, TU165, TU175) — they are identical for all four in the factory manual.
| System | Capacity | Fluid type | Applicable to |
|---|---|---|---|
| Radiator (cooling system) | 5.5 liters | LLC coolant | All models |
| Engine oil | 2.7 liters | Engine oil, correct viscosity for the season | All models |
| Transmission/gearbox (incl. hydraulics) | 12 liters | Giro oil (transmission/hydraulic oil) | All models |
| Front gearbox | 0.5 liters | Giro oil | 4WD versions only |
| Front axle | 3 liters | Giro oil | 4WD versions only |
| Power steering | 1.0 liter | Hydraulic oil | Power steering (PS) versions only |
| Fuel tank | 16 liters | Diesel JIS #2 (JIS #3 in severe frost) | All models |
| Steering axle/kingpin, center pivot | — | Grease | 2WD versions only |
| Clutch and brake pedal pivot points | — | Grease | All models |
| 2P lift bracket (X version) | — | Grease | Versions with 2P lift bracket |
An important point to remember: with this Iseki series, the transmission oil is also the hydraulic oil at the same time. So there's no separate hydraulic reservoir with its own oil — the 12 liters of giro oil in the transmission/gearbox feeds the gearbox, the differential, and the hydraulic lift system, as well as (if present) the power steering on the front axle. In practice, this means two things:

Especially in the colder months, it's important to let the engine warm up sufficiently before putting it under heavy load. The factory manual provides the following guidelines for this:
| Outside temperature | Idle warm-up time before full load |
|---|---|
| 0°C and above | 5-10 minutes |
| 0°C to -10°C | 10-20 minutes |
| -10°C to -20°C | 20-30 minutes |
| Below -20°C | 30 minutes or more |
Note: the factory manual explicitly warns that applying (heavy) load too quickly after a cold start can lead to seizing or damage to the hydraulic pump. Because the transmission and hydraulic oil share the same system in this tractor, this is especially relevant: cold, thick oil simply needs time to start flowing properly before the hydraulic pump is put under heavy load.
Changing your engine oil? Combine this with the complete filter set Iseki TU Landhope for €28.50, so you can replace the oil, oil filter, fuel filter, and air filter in one go. Not sure about your coolant level? Also check the water pump Iseki TU 14-17hp (€59.50) for leaks.
