Lovol TE Series - Maintenance of Engine Cooling System

Maintenance Instructions
5.15 Maintenance of Fuel Tank
Park the tractor on horizontal ground, turn off the engine, remove the oil drain plug under the fuel tank, and drain
the sediment at the bottom of the fuel tank.
5.16 Inspection of Tire Inflation Pressure
Check the tire pressure with a barometer. See the technical specification list of TE series tractors for tire
inflation pressure.
Note: Too high or too low tire pressure will shorten the service life of tires and affect
the driving control of tractors and cause accidents.
5.17 Maintenance of Engine Cooling System
The engine coolant can be boiled tap water or antifreeze.
The antifreeze is valid for 2 years or 1600h. After this period,
replace and flush the cooling system, and then add new
antifreeze. Cleaning of scale in cooling system: Before
maintenance, fill the cooling system with a solution of 750g
caustic soda and 150g kerosene per 10L of water. Run the engine
at medium speed for (5 ~ 10) min, and keep the solution for (10 ~
12) h (note: keep the temperature in winter to prevent freezing).
Then restart the engine and run at medium speed for 20 minutes,
and then stop the engine and drain the cleaning solution. After
the engine cools down, insert the water pipe into the water tank
for flushing. At this time, open the drain valve at the bottom of
the water tank. After cleaning, close the drain valve, add water
and let the engine run for 20min before draining the water. After
the engine cools down, add new antifreeze or cooling water as
required.
Fig. 5-20 Maintenance of Cooling System
Important: In winter, for tractors without using antifreeze, wait until the temperature of cooling
water drops below 70℃, and drain the water when the engine is idling to avoid freezing and
cracking the engine body.
