COOLING SYSTEM SERVICE WARNINGS [MZI-3.7] 

ENGINE COOLANT LEVEL INSPECTION [MZI-3.7] 

WARNING:

Never remove the cooling system cap or loosen the radiator drain 
plug while the engine is running, or when the engine and radiator are 
hot. Scalding engine coolant and steam may shoot out and cause 
serious injury. It may also damage the engine and cooling system.  

Turn off the engine and wait until it is cool. Even then, be very 
careful when removing the cap. Wrap a thick cloth around it and 
slowly turn it counterclockwise to the first stop. Step back while the 
pressure escapes.  

When you are sure all the pressure is gone, press down on the cap 
using the cloth, turn it, and remove it.  

Depending on the vehicle, the cooling fan may operate suddenly 
even when the ignition switch is turned off. Therefore, keep hands 
and tools away from the cooling fan even if the cooling fan is not 
operating to prevent injury to personnel or damage to the cooling 
fan. Always disconnect the negative battery cable when servicing 
the cooling fan or parts near the cooling fan.  

WARNING:

Never remove the cooling system cap or loosen the radiator drain 
plug while the engine is running, or when the engine and radiator are 
hot. Scalding engine coolant and steam may shoot out and cause 
serious injury. It may also damage the engine and cooling system.  

Turn off the engine and wait until it is cool. Even then, be very 
careful when removing the cap. Wrap a thick cloth around it and 
slowly turn it counterclockwise to the first stop. Step back while the 
pressure escapes.  

When you are sure all the pressure is gone, press down on the cap 
using the cloth, turn it, and remove it.  

NOTE:

If the "FL22" mark is shown on or near the cooling system cap, use FL22 
type engine coolant.  

FL22 type engine coolant is shipped as a diluted solution. Use the solution 
as is when replacing coolant.

1. Verify that the engine coolant level in the coolant reserve tank is between the F and L marks. 

If the engine coolant level is below the L mark, add engine coolant.

ENGINE COOLANT PROTECTION INSPECTION [MZI-3.7] 

1. Measure the engine coolant temperature and specific gravity using a thermometer and a hydrometer.

CAUTION:

Use engine coolant at a concentration that meets the 
environmental conditions in which the vehicle is driven, 
otherwise engine damage could occur.  

The engine has aluminum parts and must be protected by an 
ethylene-glycol-based coolant to prevent corrosion and 
freezing.  

Do not use coolants containing Alcohol, Methanol, Borate or 
Silicate. These coolants could damage the cooling system.  

Use only soft (demineralized) water in the coolant mixture. 
Water that contains minerals will cut down on the coolant's 
effectiveness.  

Engine coolant damages paint. If engine coolant does get on a

2. Determine the engine coolant protection level by referring to the graph shown in the figure. 

If the engine coolant protection level is not correct, add water or engine coolant.
