CHECKING COOLINGSYSTEMFORLEAKS

To check forleakage, applypressure tothe cooling systemwith
a tester.
Testing pressure:
157 kPa (1.57 bar,1.6kg/cm

CAUTION:
Higher thanthespecified pressuremaycause radiator damage.

REMOVAL
1. Drain coolant fromradiator.
2. Remove cylinderblockdrain pluglocated atleft front of
cylinder blockanddrain coolant.
3. Remove frontRHwheel andengine sidecover.
4. Remove drivebelts.
5. Remove frontengine mounting.
6. Remove waterpump.
CAUTION:
• When removing waterpumpassembly, becareful nottoget
coolant ondrive belt.
• Water pumpcannot bedisassembled andshould be
replaced asaunit.
• After installing -waterpump, connect hoseandclamp
securely, thencheck forleaks using radiator captester.

INSPECTION
1. Check bodyassembly forrust orcorrosion.
2. Check forrough operation duetoexcessive endplay.

WARNING:
Never remove theradiator capwhen theengine ishot; serious
burns couldbecaused byhigh pressure fluidescaping fromthe
radiator.
Wrap athick cloth around capandcarefully loosenita quarter
turn torelease built-uppressure. Thenremove thecap com-
pletely.
CHECKING COOLINGSYSTEMHOSES

Check hosesforimproper attachment, leaks,cracks, damage,
loose connections, chafinganddeterioration.

4. Before installing frontcover, remove alltraces ofliquid
gasket frommating surface usingascraper.
• Also remove tracesofliquid gasket frommating surface of
cylinder block.
5. Apply liquidgasket tofront cover.
6. Install frontcover.

• Check alignment ofmating marksonchain andcrankshaft
sprocket.
• Align oildrive spacer withoilpump.
• Place timing chaintothe side ofchain guide. Thisprevents
the chain frommaking contact withwater sealarea offront
cover.
• Make suretwoO-rings arepresent.
• Be careful nottodamage oilseal when installing front
cover.

7. Install engine frontmounting bracketandmounting.
8. Install oilstrainer.
9. Install oilpan. Refer to"Installation" in"OIL PAN" (EM-16).
10. Install crankshaft pulley.
11. Install center member.
12. Set idler sprocket byaligning themating markonthe larger
sprocket withmating markonthe lower timing chain.
