C280 oil filter Help please

[jeff.egan]

I,m in need of help again...I serviced my 1994 c280 w202 straight six
but when i came to change the oil filter i ran into trouble.The filter which
i was sold is of the element type.Is the filter housing that small black canister at the rear of the engine bay next to the inlet manifold? If so how the dickins do i get it out? do i need a special tool or is there a known easy method? If its not what i think it is,then where is the oil filter?

That's the oil filter ok ..All you do is loosen the caseing ..there should be a hex on top of it.Use proper size socket.

Oil filter housing

Hi jeff
Landovers right, a big socket does it. I use a 1 7/16 , I think that is 36 mm. The hex, domed top cover of the filter housing is usually quite tight because it has an o ring about 4 ins dia, just below the threads. You should have got one packed with the filter. The first time I did this job I found the cover very hard to undo, I had to such force on the socket that I was afraid I might break the lower housing. It doesnt need to go back on very tight as the O ring seals it. Incidentally, after you get the cover off, you have to pull the old filter off the long "spike" thing. This usually needs a good tug to free it, & a good push to get the new filter on. There should be 3 O rings with the new filter, 1 for the housing, 2 small ones that go on the "spike". I know it sounds awfuly complicated but after youve done it once its a doddle. Nice & clean too. I know Im waffling on but I used to like to fill the old spin on filters with as much oil as I could before fitting them. You cant do this with the Merc filter but Ive found that the oil light always goes out very smartly after start up.

Thanks for the info lads..all ive got to do now is get a socket! ah bugga.
Incidentally,there was only one o ring with the MANN filter but there was a new copper washer for the sump plug.I managed to bust a socket getting that out.I think some ham fisted bully has been there before.I was lucky not to rip the thread out of the alloy sump.Still upwards and onwards,we learn all the time.Bit of a different ball game to my other car,a Morris 1300.dont laugh phwaaaa!!

Are you sure that's an oil PRESSURE light??? I thought the same on my 1994 C180 (oil light goes out instantly), and then discovered to my horror that it has only an oil LEVEL light! - no oil pressure guage, no oil pressure light! I must have read the owner's manual a dozen times before I was convinced!

Come on M-B, are you claiming the only way I'll lose pressure is via loss of oil??? I can assure you, a tiny head gasket leak caused my W124 to block its oil filter with coolant, and the only way I knew was looking at the oil pressure gauge reading 0 whilst at the traffic lights.

Let's hope this doesn't happen to my C180.

Have M-B done away with oil pressure indication entirely?

Yes they do have an oil pressure sensor . It might not tell you in your handbook.It also has an oil level sensor on the sump.Both incorporate the same warning light.

Thanks landover. You've restored my confidence (I was dismayed to lose the oil pressure gauge of all my previous Benzes, but at least sharing the light with the level sensor is something).

I think they done away with oil gauges so we don't know how bad the oil pressure really is.

Oil pressure etc.

Thanks Robert for pointing out that the oil warning light maybe only activates on low level. I checked my owners book & your right it says oil level. I looked at the Haynes book wiring diagram, sure enough only the level sender is shown connected to the light. I ve got the Mitchell set of CDs (only covers US models) but none of the instrument diagrams show an oil pressure sensor. As the light does go out rather smarter than I would have expected for a pressure switch, I tend to think its for level only. Does Landover know where the pressure switch is located on a 605 5cyl non turbo?.

Oil pressure switch

Hi Forum

Can anyone give an answer to the question, "Does a 605 diesel have an oil pressure switch, if so where is it?"

Regards Peter

landrover,somehow i get the feeling that "the snapon man"would take one look at my busted socket and give a load of "yeah but no but see!"cause its from a very doggy maker in a very very doggy country where they make sockets out of plastercine and ride around in strange shaped boats which catch fire easily.

Is that one of those 72 piece socket sets that you can buy for £1.99 guaranteed to burst your knuckles?
