1997 MERCEDES-BENZ ML350 oil change

Measures for slightly sludged engine:

Oil and filter change. Purge engine, i.e. normal engine operation

in neutral, or while driving, using oil from Sheet 229.3, 228.3, or

228.5. Drain off scavenging oil after purging process (approx. 1

hour). Repeat purging process if necessary. Refill using engine oil

from Sheet 229.3, or 229.1. The first oil change after clearing the

sludge should be performed after approx. 10,000 km or beforehand;

when doing so use engine oil from Sheet 229.3.

Measures for severely sludged engine:

Engines with severe oil sludging and caking onto engine parts

and into bores have to be dismantled and mechanically cleaned.

Tough sludge residue must not enter the clean side of the oil circuit,

as otherwise, e.g. the piston oil spray and the hydraulic

compensation elements may have their functionality impaired. Refill

using engine oil from Sheet 229.3, or 229.1.

The first oil change after sludging should be performed after approx.

10,000 km; when doing so use engine oil from

Sheet 229.3.
Warranty/goodwill regulations

If in combination with engine oil sludging a warranty/goodwill claim is

submitted, then a regular documentation of maintenance must be

presented. The ASSYST printout is to be filed carefully for further

reference.

Oil sludging in combination with an exceeded oil change interval, or

because of special additives in the fuel/engine oil are costs to be

borne by the customer.

A precise application of the SAE grades in accordance with ambient

air temperatures would require more frequent engine-oil changes.

The temperature limits for the SAE grades should therefore be

regarded as guidelines, which can be exceeded or undercut for a

short duration.

7
Change wheels around if necessary retaining

the same running direction


This excludes vehicles with mixed tires at

the front and rear axle.

Between

5,000 and 10,000 km according to wear.

8
Fit wheels, tighten wheel bolts

Observe tightening sequence "1-5".

Lower vehicle, correct tire inflation pressure

(including spare wheel)


In the case of loss of tire pressure,

determine cause and replace tire if necessary.

On versions with spare tire attached to

underside of vehicle, check tire inflation

pressure of spare tire before lowering the

vehicle.
