Several Questions From a Relatively New Owner of 560 SEL
After lurking in several forums for the past two months, I've decided to inquire about several items having to do with my recently acquired 1990 560 SEL (154,000 miles).
Timining Chain: I understand that the timing chain and related parts are huge issues for this car. I am not certain but I think the chain may have been changed at 80,000 miles as the original owner had $5,000 worth of work done prior to selling the car. The car starts fine and I detect no rattle. Should I get the chain done as preventive maintenance or are there known symptons I should be aware of that will tell me when its time for a new chain?
Transmission: Car shifts hard from 2nd to 3rd especially in cold weather. Shift from 3rd to 4th is not as hard. Is this normal for this vehicle? Car goes into reverse smoothly and quickly.
I am going to do ATF change with filter and gasket? Does anyone have an opinion of Valvoline MaxLife ATF or SeaFoam Trans Treatment?
Exhaust: This car produces more exhaust than any other on the road. Generally, speaking it is white/gray colored. I cannot detect any loss of coolant, oil or transmission fluid. Any ideas on why I'm producing so much smoke? My mileage is 15 city and 19-20 highway
Hydraulic Suspension: The hydraulic fluid is so dark it appears that someone used motor oil instead of hydraulic fluid in the system. I drained the system as detailed in several posts. I got out about 1.75 quarts of fluid. Put in new fluid. Within a few days my new fluid looks like oil, which makes me think that I didn't get out all the bad fluid. Any ideas on this? The car still rides well and the accumulators are only 4 months old
Books: What manuals are available for this vehicle and where can I get them?
Stereo: The rear driver's side speaker never works while the rear passenger's side speaker will produce weak sound and then come on with a pop. Are my amplifiers the problem? If so, how much to replace, should I put in new speakers while I'm at it and is the adjustable rear seat really that difficult to remove and replace?
Driver's Sear: It is not as comfortable as I think it should be. Who is the best source for the horsehair pad and springs?
Mechanics: Does anyone have a good independent in Western NY (Buffalo area)? The local dealer has been fair with parts, but they seem high in the service area.
FYI, I am not much of a DIYer, but this car has inspired me to change my own owl for the first time in 15 years. I simply love the car. I've never had a car that rides likes this or can accelerate going uphill at 85mph.
Thanks for your help.
