Coolant Type Selection - Toyota sienna 2004 Service Manual

CAUTION
To prevent burning yourself, do not
remove the radiator cap when the en-
gine is hot.

Coolant type selection

Use of improper coolants may damage
your engine cooling system. Your coolant
must contain ethylene−glycol type coolant
for proper corrosion protection of your en-
gine that contains aluminum components.
We have used "Toyota Genuine Long Life
Coolant" in your Toyota vehicle. In order
to avoid technical problems, we strongly
recommend using "Toyota Genuine Long
Life Coolant" or equivalent.
In addition to preventing freezing and
subsequent damage to the engine, this
type of coolant will also prevent corrosion.
Further supplemental inhibitors or additives
are neither needed nor recommended.

Read the coolant container for information
on freeze protection. Follow the manufac-
turer's directions for how much to mix
with plain water (preferably demineralized
water or distilled water). The total capacity
of the cooling system is given on page
489 in Section 8.
We recommend a 50% solution for your
Toyota, to provide protection down to
about −35_C (−31_F). When it is extreme-
ly cold, to provide protection down to
about −50_C (−58_F), a 60% solution is
recommended. Do not use more than 70%
solution for better coolant performance.
NOTICE
Do not use alcohol type antifreeze or
plain water alone.
I n f o r ma t i o n P r o v i d e d b y :
The engine cooling system is integral to
maximizing performance of your Toyota
vehicle. In line with this, it is strongly
recommended that you use "Toyota

the system, as it is an ethylene−glycol
based premium antifreeze coolant with
excellent corrosion protection properties
that has been specifically formulated for
use in Toyota vehicles.

ther details about "Toyota Genuine Long
