Massive wandering on uneven roads, overheating, lo (archive)

I have a 530i E34 with an M30 (in-line six) engine manufactured in June
1988. I bought it from a used-car lot in Cotonou, Rep. of Benin in Africa.
I'm in Lagos, Nigeria. Now, I have these problems which I'll really
appreciate some help or hints on.

1. The shocks are really bad, and I'm planning to change them within the
next few days. However, I want to know if the bad shocks are the cause of
the car wandering violently on uneven road surfaces, or could it be a
problem with the steering or suspension? I'd like to take the opportunity
of replacing the shocks to fix any other problems the car may have with its
suspension and/or steering?

2. The car sometimes overheats in traffic if I turn the ignition off and on a few times, maybe to save fuel. However, leaving the engine running for upwards of 30 - 45
minutes continously does not cause it to overheat. Is there something wrong with the
cooling system?

3. Related to the above: Will changing the thermostat to one with a lower
temperature rating reduce the engine running temperature, and therefore the
tendency to overheat?

4. Is there anything called a 'tropicalised' radiator, and will fitting one
help my cooling system?

5. What is wrong with fixing the fan clutch so that the fan runs all the
time? Everybody says not to do it, but they never give a reason.

6. Output power and acceleration are much reduced with the air conditioning
on. Fuel consumption is also way up. What could be causing this?

7. Fuel consumption is like 17 - 19 litres / 100 km. I feel this is
excessive. Is it? The engine has 217,000 km on it, but does not smoke.
Idling is slightly rough - not so noticeable though.

I'll really appreciate your help on these matters.

Sincerely,

Muyiwa Taiwo
Lagos, Nigeria
