ENGINE MAINTENANCE (VQ35DE)
REFILLING ENGINE COOLANT
1. Install the radiator drain plug. If the cooling system was drained completely, install the reservoir tank and
the cylinder block drain plugs.
• The radiator must be complete ly empty of coolant and water.
• Apply sealant to the threads of the cylinder block drain plug. Use Genuine High Performance
Thread Sealant or equivalent. Refer to GI-21, "Recommended Chemical Products and Sealants"
.
CAUTION:
Do not reuse copp er sealing washers.
2. If disconnected, reattach the upper radiator hose at the engine side.
3. Set the vehicle heater controls to the full HOT and heat er ON position. Turn the vehicle ignition ON with
the engine OFF as necessary to activate the heater mode.
4. Install the Tool by installing the radiator cap adapter onto the radiator neck opening. Then attach the gauge body assembly
with the refill tube and the venturi assembly to the radiator cap
adapter.
5. Insert the refill hose into the coolant mixture container that is placed at floor level. Make sure the ball valve is in the closed
position.
• Use recommended coolant or equivalent.
Refer to MA-11, "FOR USA AND CANADA : Fluids and Lubri-
cants".
CAUTION:
Do not use any cooling system additives such as radiator
sealer. Additives may clog th e cooling system and cause
damage to the engine, transm ission and/or cooling system.
6. Install an air hose to the venturi assembly, the air pressure must be within specification.
CAUTION:
The compressed air supply must be equipped with an air dryer.
7. The vacuum gauge will begin to rise and there will be an audible hissing noise. During this process open the ball valve on the refill hose slightly. Coolant will be vi sible rising in the refill hose. Once the refill hose is
full of coolant, close the ball valve. This will purge any air trapped in the refill hose. Radiator drain plug : Refer to
