Recommended Egine Coolant; Radiator Cap - Hyundai H-1 Owner's Manual

Maintenance
Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F and L marks on the side of the
coolant reservoir when the engine is
cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F, but do not overfill. If frequent
additions are required, see an authorized
HYUNDAI dealer for a cooling system
inspection.
