Cooling PDF

The document describes the cooling system inspection procedure for a 2GR-FE engine. It involves inspecting the cooling system for leaks by pressurizing the radiator, checking the engine coolant level and quality, and inspecting the radiator cap sub-assembly. The cooling fan system uses the engine coolant temperature switch and fan relay to control the electric cooling fans according to coolant temperature and air conditioner use.

2GR-FE COOLING – COOLING SYSTEM CO–1

COOLING SYSTEM
ON-VEHICLE INSPECTION
1. INSPECT COOLING SYSTEM FOR LEAKS
CAUTION:
Do not remove the radiator cap while the engine and
radiator are still hot. Pressurized, hot engine coolant
and steam may be released and cause serious
burns.
(a) Fill the radiator with coolant and attach a radiator
cap tester.
(b) Warm up the engine.
(c) Using the radiator cap tester, increase the pressure
inside the radiator to 118 kPa (1.2 kgf/cm2, 17.1
psi), and check that the pressure does not drop.
If the pressure drops, check the hoses, radiator or
water pump for leaks. If no external leaks are found,
check the heater core, cylinder block and head.
A128110
2. CHECK ENGINE COOLANT LEVEL AT RESERVOIR
(a) The engine coolant level should be between the
"LOW" and "FULL" lines when the engine is cold. If
low, check for leaks and add "TOYOTA Super Long
Life Coolant" or similar high quality ethylene glycol CO
based non-silicate, non-amine, non-nitrite, and non-
borate coolant with long-life hybrid organic acid
technology up to the "FULL" line.
3. CHECK ENGINE COOLANT QUALITY
(a) Remove the radiator cap.
CAUTION:
Do not remove the radiator cap while the engine
and radiator are still hot. Pressurized, hot
engine coolant and steam may be released and
cause serious burns.
(b) Check if there are any excessive deposits of rust or
scale around the radiator cap and radiator filler hole.
Also, the coolant should be free from oil.
HINT:
If excessively dirty, replace the coolant.
(c) Reinstall the radiator cap.
CO–2 2GR-FE COOLING – COOLING SYSTEM

INSPECTION
1. INSPECT RADIATOR CAP SUB-ASSEMBLY
NOTICE:
• If the reservoir cap is contaminated , always rinse
it with water.
• Before using a radiator cap tester, wet the relief
valve and pressure valve with engine coolant or
water.
• When performing procedures "A" and "B" below,
keep the tester at an angle of over 30° above the
horizontal.
(a) Using a radiator cap tester, slowly pump the tester
and check that air is being released from the
vacuum valve (Procedure "A").
Pump speed:
1 push every 3 seconds or more
NOTICE:
Push the pump at a constant speed.
If air is not being released from the vacuum valve,
replace the reservoir cap.
A051912 (b) Pump the tester and measure the relief valve
opening pressure (Procedure "B").
Pump speed:
CO 1 push within 1 second
NOTICE:
The pump speed above should be followed for
the first pump only. If will close the vacuum
valve. Once the vacuum valve is closed, the
pump speed can be reduced.
Standard opening pressure:
69.0 to 112.8 kPa (0.70 to 1.15 kgf/cm2, 10.0 to
16.4 psi)
HINT:
Use the tester's maximum reading as the opening
pressure. If the maximum reading is less than the
minimum opening pressure above, replace the
radiator cap.

radiator hoses several times by hand.
CO (f) Stop the engine and wait until the coolant cools
down to room temperature (Procedure "F").
(g) Remove the radiator cap and check the coolant
level inside the radiator (Procedure "G").
If the coolant level is below the full level, repeat
procedure "C" to "G" until the coolant level. If it is
below the full line, add coolant.
3. CHECK ENGINE COOLANT LEAKS
(a) Fill the radiator with coolant and attach a radiator
cap tester.
(b) Pump it to 118 kPa (1.2 kgf/cm2, 17.1 psi) and
