Engine Coolant Replacement
WARNING:
To help avoid danger of being burned, do not remove
radiator cap while engine and radiator are still hot. Scald-
ing fluid and steam can be blown out under pressure if
cap is taken off too soon.
CAUTION:
When changing engine coolant, use mixture of 50% spec-
ified water and 50% ANTIFREEZE / ANTICORROSION
COOLANT for the purpose of corrosion protection and
lubrication.
Change engine coolant with new one referring to "Cooling System
Flush and Refill" in Section 6B or 6B2.
Exhaust System Inspection
WARNING:
To avoid danger of being burned, do not touch exhaust
system when it is still hot. Any service on exhaust sys-
tem should be performed when it is cool.
When carrying out periodic maintenance, or the vehicle is raised
for other service, check exhaust system as follows:
• Check rubber mountings for damage, deterioration, and out
of position.
• Check exhaust system for leakage, loose connections, dents
and damages.
If bolts or nuts are loose, tighten them to specification.
• Check nearby body areas for damaged, missing, or misposi-
tioned parts, open seams, holes, loose connections or other
defects which could permit exhaust fumes to seep into the
vehicle.
• Make sure that exhaust system components have enough
clearance from the underbody to avoid overheating and pos-
sible damage to the floor carpet.
• Any defects should be fixed at once.
Spark Plugs Replacement
Replace spark plugs with new ones referring to "Spark Plugs
Removal and Installation" in Section 6F or 6F2.
