What did you do to your E9 today?

I changed the oil in the E9 and E23 today. Had not changed either since @sfdon finished with each of them.
Not surprisingly, the E23's oil was considerably more 'used' than the E9's as I probably had 4 or 5 times the miles on the 7 compared to the Coupe.
With my knee still not well (and my back not being good either), I had help.
The fella doing the work for me could not get over how clean these cars were.

He used to work at the place I have my cars worked on and now has set up his own shop at his house (stand alone shop that is actually set up very well).
When he was at the original place, he worked on my F250, Escalade, 911, 740iL and the 728i (before that one went to Alameda).
He had never seen an E9 before - literally. My 728i is also the only E23 that he has ever seen. He's a young fella who is very good for what I want him to do (the basics) - probably about 28 years old. He is into Audi's and Sub's. But - he is happy to expand his horizons. LOL - I brought the oil and filters. He did the work.
He had his routine for safety checks and such for cars he has in for work on - He skipped that on the E9 and E23. LOL They were obviously in PERFECT shape (his words). Plus, I was in a hurry. :)

I'm set now for the next year or so.

Sorry for the late reply...

The paint on my 2000CS is now just over 7 years old. I have never polished the paint, only ever waxed it since the repaint. My paint/body man was over the top from prep to final wet sand and polish and the results speak for themselves. I do keep it as clean as possible with very minimal contact with any towel; I use only the softest, clean microfiber and a soft touch. I wax it often with Maguires Gold Class Carnauba (always been my favorite wax for single stage paints). I use Griot's Best of Show detail spray between deep cleanings. I live in Texas and that detailer can be applied in direct sunlight, which helps a lot.

Another key to clean paint is a good car cover. I bought a custom garage cover from a forum member, Dan Mooney (he doesn't appear to be active here, anymore but I know he's still around the Austin area). Having a garage cover REALLY helps keep the paint from getting contaminants imbedded into the paint. I highly recommend one.

This car has seen some miles, too. I don't take it out as often as I should, but it's been across the country on several jaunts. I just care for it as best as I can, considering all the blood, sweat, and tears put into it.

Thanks for the fine comments, this car never fails to attract attention. "Mister... WHAT is that??"

I use this procedure, and have some suggestions.

You don't need to hold the expansion tank hose end as high as you can, you merely need to hold it above anywhere in the cooling system that air could be hiding. Best to hold it where you can easily see the end of the hose.

When blowing in the hose attached to the top of the radiator, your objective is to push out all of the air in the system. You know this is done when a very small amount of coolant comes out of that hose end. You want to blow hard enough that a small amount of coolant comes out, but not so hard that the coolant sprays all over the place. So, hold the hose end where you can see it and with the end square to the coolant tank. This helps you determine how hard to blow. Second, wrap a rag around the hose to catch the coolant so it doesn't get on your car or run down your arm.

Hi, would you mind clarifying – the original post says to blow into the expansion tank, and you suggest blowing into the radiator – does it matter which or is one of the posts incorrect?

Many thanks, Chris

Remove the end of the radiator overflow hose attached to the overflow tank. Install a 2' hose onto the overflow tank in its place. Hold the radiator hose up in the air with your thumb lightly on the end, I also wrap some paper towel around the end to catch the coolant. Gently blow into the temporary hose attached to the tank until coolant comes up out of the radiator hose. I then remove the tank hose and with my thumb still on the radiator hose, install it back on the tank.

This is a good technique, but I think a better one is to drill a small hole in the thermostat and clock it at 12:00.

Chris - Steve has clarified this nicely. You blow into the end attached to the overflow tank and watch the end of the hose attached to the radiator. I think I'll edit my original post.

Brill, many thanks. Unfortunately I think I’ve got a cracked cylinder head - I’ve bled many times and have a constant stream of bubbles coming into my expansion tank, which increase with revs. Guess it’s head off time, groan

Hiya. Sorry, I wasn’t sure what you meant? Useless if I’ve got a leaking head? Sadly true! Or that it’s a useless procedure for bleeding the coolant system?

Cheers Chris

dear chris, both cases is true, but it was not my intention to mock on your leaking head, that came in a later post than the one that i responded to (sorry for head)
i you can see i responded to your first thread
it is useless for bleeding, yes
