Engine Oil Level—Checking; Engine Oil Service; Api Service Grade Certified; Sae Viscosity - Chrysler 2000 LHS Owner's Manual

9 - 20 2.7L ENGINE
DIAGNOSIS AND TESTING (Continued)
CAUTION: Do not exceed 20.6 kPa (3 psi).
(5) If the leak is not detected, very slowly turn the
crankshaft and watch for leakage. If a leak is
detected between the crankshaft and seal while
slowly turning the crankshaft, it is possible the
crankshaft seal surface is damaged. The seal area on
the crankshaft could have minor nicks or scratches
that can be polished out with emery cloth.
CAUTION: Use extreme caution when crankshaft
polishing is necessary to remove minor nicks and
scratches. The crankshaft seal flange is especially
machined to complement the function of the rear oil
seal.
(6) For bubbles that remain steady with shaft
rotation, no further inspection can be done until dis-
assembled.
(7) After the oil leak root cause and appropriate
corrective action have been identified, refer to Crank-
shaft Oil Seal—Rear for proper replacement proce-
dures.
SERVICE PROCEDURES
ENGINE OIL LEVEL—CHECKING
The best time to check engine oil level is after it
has sat overnight, or if the engine has been running,
allow the engine to be shut off for at least 5 minutes
before checking oil level.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
reading (Fig. 14). Add only when the level is at or
below the ADD mark.

CENTER IN YOUR AREA.

API SERVICE GRADE CERTIFIED

Use an engine oil that is API Service Grade Certi-
fied. MOPAR provides engine oils that conform to
this service grade.

SAE VISCOSITY

An SAE viscosity grade is used to specify the vis-
cosity of engine oil. Use only engine oils with multi-
ple viscosities such as 5W-30 or 10W-30. The
preferred viscosity oil for the 2.7L engine is 5W-30.
These oils are specified with a dual SAE viscosity
grade which indicates the cold-to-hot temperature
viscosity range. Select an engine oil that is best
suited to your particular temperature range and vari-
ation (Fig. 15).

ENERGY CONSERVING OIL
An Energy Conserving type oil is recommended for
gasoline engines. The designation of ENERGY CON-
SERVING is located on the label of an engine oil con-
tainer.
