83 300D- Getting up to speed
I'm trying to get my 83 300d up to par for daily driving. I have a 1 1/2 hour commute round trip so I want to get all the simple stuff out of the way now. So far I've changed the air, oil, and fuel filters. I just got done doing a oil change I used Delo 400 10w-40. Man you should've seen the nasty old oil I drained from it. Now I'm going to do a transmission fluid and filter change. After I get done with that I'm considering a coolant system flush with citric acid. I'm not having any problems with overheating I just figure it might be a good idea?
Is there anything else I should flush/change? Thanks for any info, Jared

The oil in the differential is probably from the factory. Now you can really say "nasty old oil". The engine oil is "clean" compared to this stuff.

You could change the power steering fluid and filter. It's also likely to be as old as the car. The simple way is to remove the old filter and then suck out as much fluid as you can (an old turkey baster works well). Then install a new filter and fill the reservoir with clean fluid. There is a special "power steering fluid" made for the purpose, which I use, but in the past I have also used automatic transmission fluid.
The "correct" way is to disconnect the low-pressure hose, plug the port in the pump, and put the hose in a drain bucket. With one person starting the engine and moving the steering wheel back and forth, the second person keeps an eye on the bucket and pours fresh fluid into the reservoir. When the fluid coming out of the hose is clean, you have purged the entire system. Stop the engine, reconnect the hose, install filter and fill reservoir. Remember to properly recycle the used fluid. Buy your wife a new turkey baster.

Don't forget to change the fluid in the torque convertor while you are doing the tranny pan. Make sure that you clean out the hexes on these two plugs before trying to bust them loose, you want the hex wrench to go in as jar as possible.

I was just reading about draining the rear differential. I think I will do that, I'm sure it couldn't hurt. Anything to make my baby happy.
P/S flush is probably a good idea as well, thanks. Is there a specific P/S Fluid I should get? Or will ATF work? I do plan to drain the torque convertor when I do the tranny. Lucky me I already have a 1 1/16th socket. So I think I should be good to go, hopefully it'll cool down and I'll do this later today. Thanks for all the pointers. Any other tips are appreciated.
