After all the coolant is removed, close both drain valves.
Recycle or dispose of coolant in an environmentally safe
manner.
Mix the coolant in a s eparate container. (See Contents,

NOTE: The loader backhoe is factory filled with
ethylene glycol. DO NOT mix propylene glycol
with ethylene glycol.
Add premixed coolant; 50% water and 50% et hylene
glycol to the recover tank if the coolant level is low.
One gallon and one pint of e thylene glycol mixed with
one gallon of water is the correct mixture of coolant to
provide a -34°F (-37°C) freeze protection.
Use a refractometer to check the condition of ethylene
glycol in your cooling system.
Fill the radiator with the premixed coolant until it is full.
Run the engine at idle speed for about 5-10 minutes to
remove the air from the cooling system (leave the
radiator cap off during this operation).
Stop the engine. Check the coolant level and add as
needed to bring it up to the radiator filler neck. Install the
radiator cap and tighten.
