manuál je tu, na stránce 9,
závěr je jasný,
až na konci bod 3 červeně, jinak kopíruju radši celý:
1. DRAIN ENGINE COOLANT
NOTICE:
To avoid the danger of being burned, do not remove
the radiator cap sub-assembly while the engine and
radiator assembly are still hot. Thermal expansion
will cause hot engine coolant and steam to blow out
from the radiator assembly.
(a) Loosen the radiator drain cock plug.
(b) Remove the radiator cap sub-assembly.
(c) Loosen the cylinder block drain cock plug, then
drain the coolant.
2. ADD ENGINE COOLANT
(a) Tighten all the plugs.

(b) Pour engine coolant into the radiator assembly until
it overflows.
Capacity:
M/T 4.8 liters (5.1 USqts, 4.5 lmp. qts)
A/T 4.7 liters (5.0 USqts, 4.4 lmp. qts)
NOTICE:
Do not substitute water for engine coolant.
HINT:
• Use of improper engine coolant may damage the
engine coolant system.
• Use only Toyota Super Long Life Coolant or
similar high quality ethylene glycol based nonsilicate,
non-amine, non-nitrite, and non-borate
engine coolant with long-life hybrid organic acid
technology (coolant with long-life hybrid organic
acid technology consists of a combination of low
phosphates and organic acids).
(c) Check the engine coolant level inside the radiator
assembly by squeezing the inlet and outlet radiator
hoses several times by hand. If the engine coolant
level goes down, add engine coolant.
(d) Install the radiator cap sub-assembly securely.
(e) Slowly pour engine coolant into the radiator
reservoir until it reaches the FULL line.
(f) Warm up the engine until the cooling fan operates.
(1) Set the air conditioning as follows while
warming up the engine.
(2) Maintain the engine speed at 2,000 to 2,500
rpm and warm up the engine until the cooling
fan operates.
(g) Stop the engine and wait until the coolant cools
down.
(h) If the engine coolant level is below the full level,
perform steps (b) through (g) again and repeat the
operation until the engine coolant level stays at the
full level.
(i) Recheck the engine coolant level inside the radiator
reservoir tank assembly. If it is below the full level,
add engine coolant.
3. CHECK FOR ENGINE COOLANT LEAKAGE (See
page CO-1)!!!!!!
edit: vlastně ten bod CHECK FOR ENGINE COOLANT LEAKAGE se vyskytuje na konci každého zásahu do systému, nejen po výměně kapaliny, jak jsem kopíroval výše.
