Hi all New 1999 CLK320 owner

I've been reading this forum for a few days now and am really impressed with how kind and knowledgeable the members are. The car is really clean inside and out. I'm planning on doing some service on it this weekend. I won’t be able to sleep right until I’ve changed ALL the fluids. This is where i need your expertise. I tried searching the web and this site (I always search first) and I'm unsure as t what I have found. So here goes...
1: engine oil. I believe that it requires 8.5 qtrs. of Mobil 1 0w-40
I read Greg210's excellent DIY article on changing it but would love to know the size of the oil filter cap wrench that he used so I can buy one.
2: Transmission fluid change. I'm going to have my mechanic do the change but I want to provide the best fluid and how much for the job. Also what else has to be changed such as gaskets and the like so that I can make sure that all is right.
3: power steering fluid change. Again what do you all use and how much?
4: coolant system. Prestone 50/50 or something else?
Sorry if this topic has been covered but I just couldn't find it. Of course the car did not come with the manual and I plan on ordering one a.s.a.p. Any help would be greatly appreciated Thanks Slobodan
I just picked up my 99 about a month ago and did the same. A few notes re your question about the tranny
See this thread about the parts required for the tran oil change. Change also the mentioned adapter plug and O-ring as it likely leaks.

Maybe look into replacing: Draglink assembly and Steering damper, should tighten up your steering (along with tightening up the Gearbox bolts in the driver's side front-wheel well).

And some other regular parts usually replaced under regular maintenance are: the 12 spark plugs (you'll prob want to order the special wrench to make the job much easier), engine air filter, cabin air filter and fuel filter.
PM me if you want a list of all the parts I ordered when I did all the work and where I sourced them from.
Cheers and congrats!

For number 4, I would NOT use Prestone. Zerex G-05 is an approved fluid.

Note that squeaking from both the front seats get worse when the seats are set lower because they rub more on the plastic sheathing on the outsides of the seat.... either file away some of the plastic sheathing or put something in between the seat and sheathing to block them from making contact.
