PRECAUTIONS
[QR25DE]
PRECAUTIONS PFP:00001
Precautions for Liquid Gasket EBS00DVN
REMOVAL OF LIQUID GASKET
q After removing the mounting bolts and nuts, separate the mating
surface using a seal cutter and remove the sealant.
CAUTION:
Be careful not to damage the mating surfaces.
q In areas where the cutter is difficult to use, use a plastic hammer
to lightly tap the areas where the sealant is applied.
CAUTION:
If for some unavoidable reason a tool such as a flat-bladed
screwdriver is used, be careful not to damage the mating sur-
faces.
PBIC0002E
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old sealant adhering to the mating
surface.
q Remove the sealant completely from the groove, mounting
bolts, and bolt holes.
2. Clean the mating surface thoroughly to remove adhering mois-
ture, grease and foreign materials.
3. Install the sealant tube into the tube presser.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-43, "RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
PBIC0003E
4. Apply the sealant without breaks to the specified area with the
specified dimensions.
q If there is a groove for the sealant application, apply the sealant
to the groove.
EMA0622D
q As for the bolt holes, normally apply the sealant inside the holes.
If specified, it should be applied outside the holes. Make sure to
read the instructions in this manual.
q Within five minutes of sealant application, install the mating
component.
q If the sealant protrudes, wipe it off immediately.
q Do not retighten after the installation.
q After 30 minutes or more have passed from the installation, fill
the engine with the correct oil and coolant. Refer to MA-13,
"RECOMMENDED FLUIDS AND LUBRICANTS" . SEM159F
CAUTION:
If there are specific instructions in the service manual, observe them.

ENGINE OIL
[QR25DE]
ENGINE OIL PFP:KLA92
Inspection EBS00DVS
OIL LEVEL
q Before starting the engine, check the oil level. If the engine is
already started, stop it and allow 10 minutes before checking.
q Check that the oil level is within the range on the dipstick.
q If it is out of range, add oil as necessary. Refer to MA-13, "REC-
OMMENDED FLUIDS AND LUBRICANTS" .
PBIC0249E
OIL APPEARANCE
q Check the oil for white turbidity or heavy contamination.
q If the oil becomes turbid and white, it is highly probable that it is contaminated with coolant. Determine the
cause and correct as necessary.
OIL LEAKAGE
Check for oil leakage around the following areas:
q Oil pan
q Oil pan drain plug
q Oil pressure switch
q Oil filter
q IVTC cover
q Front cover
q Mating surface between cylinder block and cylinder head
q Mating surface between cylinder head and rocker cover
q Crankshaft oil seal
OIL PRESSURE CHECK
WARNING:
q Be careful not to burn yourself, as the engine oil may be hot.
q For M/T models, put the gearshift lever in the Neutral "N" position. For A/T models, put the selec-
tor lever in the Park "P" position.
1. Check the oil level.
2. Remove the under cover, using power tools.
3. Remove the oil pressure switch to connect the oil pressure
gauge.
4. After warming up the engine, check that oil pressure corre-
sponding to the engine speed is produced.
