Winterizing and storing Hinomoto C142 to C174
Here is how to winterize your Hinomoto C142, C144, C172, and C174 and store it properly. The emphasis is on coolant and frost protection, as the cylinder head is already the weak point on these engines.
Suitable for the entire series: Hinomoto C142, C144, C172, and C174. The stated values apply to the C142 and C144. The C172 and C174 are not listed in the workshop manual. Capacities and adjustment values for those models have not been confirmed.

Hinomoto C142 to C174 coolant and frost
Check the coolant for frost protection before the first frost. If the fluid freezes, the engine block or cylinder head can crack. The cylinder head in particular is already the weak point on these engines.
If the cooling system is contaminated or clogged, flush it before filling with new fluid. Also blow out the radiator core. A clogged radiator core, for example due to grass clippings, is one of the causes of overheating.
Tip: fill with Coolant 5 L (SKU-125001). The cooling system of the C142 and C144 holds 3.0 L. Flush a contaminated system first with Radiator Flush 250 ml (SKU-125007).
How much coolant do you need? 3.0 L for the C142 and C144, so a 5 L bottle is enough. For the C172 and C174, the capacity is not confirmed.
Hinomoto C142 to C174 winter checklist
- Check coolant for frost protection and replace if necessary
- Blow out the radiator core
- Check V-belt (C142 and C144: 8 to 10 mm deflection)
- Change engine oil and filter before storage
- Fill the fuel tank completely to prevent condensation
- Drain water from the filter bowl
- Measure glow plugs (C142 and C144: approx. 0.23 ohm each)
- Grease all grease nipples
- Check tires
The general list can be found in the winterizing checklist for a compact tractor.
What do you measure on the glow plugs? Approx. 0.23 ohm each for the C142 and C144. Replace a defective glow plug with the Glow plug C142-C174 (SKU-551303-1).
Storing Hinomoto C142 to C174
Store the tractor in a dry place. Charge the battery or connect a trickle charger. If that is not possible, disconnect the negative terminal. Cover the exhaust.
After sitting idle for a long time, there may be water in the diesel. Therefore, fill the tank before storage and check the filter bowl. Long periods of inactivity can also cause the plungers of the injection pump to stick.
