Information
–
Use clean, pH-neutral, filtered and softened fresh water.
GROVE recommends using demineralized water.
–
Cummins specifies the use of distilled water.
–
Do not use ditch water, industrial drain water, salt water, sea
water or rain water.
–
Always fill in mixture of water and anti-freeze agent. Observe
the manufacturer's recommended mixing ratio. Mix before
filling.
Make sure the water has the following properties:
pH value
Chloride content
Sulfate content
Water hardness
Information
If the coolant concentration is too high, the cooling and antifreeze
properties will be adversely affected. Observe the coolant manu-
facturer's specifications.
GROVE cannot be held liable and will void any warranty if any
coolant other than the one specified is used.
Risk of scalding from coolant steam.
– Let the engine cool down before draining coolant.
Opening the coolant tank will cause hot coolant to evaporate.
Persons in the vicinity can be scalded.
Information
Collect draining coolant and dispose of it in accordance with regu-
lations.
Risk of cooling system failure and engine damage from using
incorrect coolant or coolant additives.
– Do not mix coolants.
– Do not use cooling system sealing agents or antifreeze
containing sealing agents.
Adding or mixing different coolants or coolant additives can
cause sludge accumulation or gelatinization and clog the radi-
ator, causing the engine to overheat or the cooling system to
fail, resulting in engine damage.
Information
The coolant must be changed if a routine check of the coolant level
reveals the presence of lubricating oil or noticeable cloudiness.
