Thanks for the advice Alex. You are right, I have
to become more of a legitimate home mechanic and
buy some air tools. Also, thanks for the heads
up on the ball joint puller from Bav Auto. I
thought maybe one size fit all....guess not. I want to tackle my front suspension and replace everything and add a modest drop to the car by adding H&R springs as Carlos did. I look forward to the challange.
As far as the heater core goes, its quite a job
but eminently doable. I couldn't have done it
without the indispensible help of people on this
board...particularly long lost Stefan who as you
may recall went in not once but twice...he should be knighted!...and to create a comprehensive website to share with everybody in his second language no less...he's a pretty remarkable guy. I downloaded all I could find about heatercore
replacement...many have posted...thanks JFD for
your advice about getting the center consile
wood facia off..if you pull wrong you can break
off the bottom clips...stuff like that... every- thing is there. I do have a tip for you so if you get ready to do it give me a shout. My core didn't look too bad...O-rings were beat as expected. You probably are aware that BMW clearly was running too much cooling system pressure....hence the radiator cap recall which
undoubtly contributed to premature 0-ring failure....not to mention intermittent heater core/plastic piping failure.... I'll leave it there. I took the precaution and replaced the core, plastic pipes and O-rings. You don't want to go back in there anytime soon and
of course use original BMW parts. I've taken my
time and refurbished and cleaned everything before
reassembly...I'm pretty meticulous.
Enough rambling...wish you the best in the New

Happy Holidays George,

You have to buy some air tools! The impact wrench is especially useful (if not for removing nuts then for venting frustration!). I bought a portable 5HP compressor from Sears for about $300 and a five-piece tool set from Home Depot for $100. The impact wrench is invaluable (I have semi-retired my six foot "persuader", BMW special tool #2).

I bought the balljoint tool from Bavarian Autosport about three years ago. It works well for tie-rod balljoints but not the larger and less-accessible thrust arm balljoints. I have replaced all the tie-rods on the 735i and the 2002 so the $30.00 has more than paid for itself.

Incidentally, congratulations on the heater core replacement. No smell inside anymore? How long did the job take? Did you replace the core as well as the supply pipes and seals? I spent the holidays replacing the brake light switch (again), fixing twisted seat backs (again), and replacing the radiator (again). However, everything is easier the second time. I have just been rained-out with the radiator replacement so the car is currently on ramps without coolant.

Happy Holidays Alex,
OK you used an air chisel...that means you have
air....(brilliant huh?) guess what...I know, I
know I should but....I don't. You know the
pickle fork story...will ruin the ball joint seal
every time...hence the ball joint puller inquiry.
Don't want to pony up for the Bav Auto puller.
Liked your comment about about the custom thrust
arrm nut removal tool. Funny stuff as to have a sense of humor with these cars don't you? I, like you, will be sacrificing one of my shiney Craftsman 22's if BIG DADDY'S advice doesn't come through. Incidently, can you help Sergio below?...check out his post and my
Best Regards,
