Getting ready to start work on the 92 400E I picked up. First problems I need to tackle are a leak at the front left of the car {looks like PS fluid?} And a strange loud whinding grinding noise when starting the car. Other than that, the car runs good. Is there anything else I should do/check to start off with I figure fluids/plugs/filter?? O ya the belt is real loose my budy noticed could this be causing the start up problem? Lastly what is the general opinion on seafoaming through the Intake man and a engine flush??

I'd also like to say thanks to the masses out there for there great input on these great cars!!!!!

What mileage?

First I'll answer your last question. No seafoam or additives. I'd change it and put Mobil-1 15W50 oil in the engine. Filters- ps fluid is special. Trans fluid and filter (drain the tq converter).
Yes, you probably have a leaky PS pump. Return hose can be purcahased by the meter. I think the PS pump it's ussually an o-ring or front seal. Can be done, takes a while. MB dealership is probably the best place to get the parts for that.
Loose belt? Sounds like a failed belt tensioner. I'd pull the and inspect stuff. Probably could an idler bearing etc.
Sicne you just purchased the car- might want to measure the motor mounts- they are probably colapsed. Plugs make sure you use the right plugs(no platniums or resistors)... get them at the dealer $3 each.
Starter- you'll have to just pull it and see what is going on..

I've just got one too- should be here on Tuesday.
