Maintenance
Check all the cooling system hoses
and heater hoses. If necessary,
replace any swollen or deteriorated
one. The coolant level should
be between F and L marks
on the coolant reservoir,
when the engine is cool.
When the coolant level is low, add
distilled (deionized) water. Bring up
the level to F, but do not overfill.
When frequent additions are
required, have an authorized
EQUUS dealer inspect your cooling
system.
Recommended engine coolant
When adding coolant, use the deionized water, distilled water or
soft water. Never add hard water in
the coolant. An improper coolant
mixture may result in serious mal-
function or engine damage.
The engine parts are made of alu- minum and must be protected by
an ethyleneglycol-based coolant
from any corrosion and freezing.
DO NOT USE alcohol or methanol coolant, nor mix them with the
authorized coolant. Do not use the solution of which
the antifreeze portion is above
60% or below 35%. This may
reduce the solution effects.
Mix the water and antifreeze in the half-and-half ratio. This solution will
work in most situations.
For the proper mixture ratio, refer to
the following table.
Information
The half-and-half ratio solution of
water and antifreeze is effective at a
temperature of -31°F (-35°C) and
higher.
