5ktq opinions (summary of replies)
I solicited the collective wisdom of this group
a couple of weeks ago on what seems to be one
of the (old ?) favourites here - the 5kCSTQ. Steve B
suggested that I summarize the replies I received
so that Dan S could possibly include it in the
(perennially nascent :) FAQ.
The depth of the replies I received is quite amazing
and should definitely help anyone in the market for
For the moment, I've sort of slinked away from considering
the car. Don't get me wrong - I think it's one of the
best cars I have driven, to say nothing of being one
of the best values for the money in terms of the sheer
technological sophistication it represents. However, the
"little (and not so little) things that go wrong" seem
to add up to quite a massive number over a year - something
that I dread to undertake on a graduate student stipend.
Thanks once again for your replies, and I sure hope the
following helps someone :

Not too likely IMHO. Ask the owner if they are needing to
add fluid to the hydraulic oil tank (just to the right of
the brake M/C against the firewall, right is as viewed from
the driver's seat). IMHO, this is one of the biggests risks
for the car. I've noticed that the boot that goes over the
steering rack tends to disintegrate on the side that faces
the firewall ... the part you can see may look great.
> 2. How would I check if the turbo were on its last legs ?
I wouldn't worry too much about the turbo ... you might want to
check the afterrun cooling pump functionality. After you shut
down the engine when the engine is fairly warm within a couple
of minutes the radiator fan should come on and the aux cooling
pump for the turbo should as well. You can probably feel the
pump vibrating at this time. On my '88 5k I had to replace the
pump because the hose fittings were broken, and on the '87 5k
someone had removed the pump from the circuit completely because
the pump housing was busted. They didn't take the time to dis-
connect the electrical connector, sou you could watch the
impeller spin ... perhaps I can loan it to you as a tester ... ;-)

Try the CC in all modes and make sure that air will come out of all
the vents. You might want to try running the temperature from max
cold to max hot as well. There is a little grate mounted on the
dash ... this is for sensing the interior temperature. When you
change the settings you should hear a slight hissing sound from
this area for a second or two. The last thing to do is to check the
recirculate door to see that it is working. Above the passenger's
footwell you will notice the door that allows air from the interior
of the car to recirculate through the climate control. For most
cases this door should be closed, but if you set the CC to A/C and
the temp to "LO" the door should open. If it is open at other
times or never moves then you have a problem with the spring or
actuator mount. This is also a fairly common problem, and there
is a kit you can get from the dealer to fix it. The main problem
this can cause is in the winter if the system is always in recirc-
ulate mode the inside of the windshield will fog up ...

The PA does not provide steering boost when the engine stops ... it
only supplies the brakes.
When you're driving the car try a couple panic stops. If the brake
warning light comes on with a red triangle you've got a problem. It
may be true that the pressure sensor is disconnected ... it is located
behind the brake master cylinder and servo and it is on the opposite
side from the fender [same side as the hyd fluid reservoir above] and
you have to look in the right place to see it. It should be pretty
obvious if the wires are disconnected. The other thing you might
notice that would indicate a failure of the PA is when you tested the
panic stop if you found that you had to press really hard on the pedal
to get the car to slow down quickly, but as time progressed you had to
let up on the pedal to keep the wheels from locking up [turn off the
ABS!] this indicates that the PA is not providing that needed reserve.

- - Look for holes in the exhaust system.
- - Ask the owner when the last time the timing belt & water pump have
- - Make sure that all of the windows work, both from the driver's door
and the individual switches. It may be true that one switch works
while the other does not, that probably means a switch ... if it
doesn't work from either switch, or goes only in one direction you
may have a problem with either the motor or the wiring being flexed
in the door hinge area. Test the sunroof too.

... you never said how many miles the car has. $4500 for an '88
probably isn't that far off ... I usually check the Kelley BB before
even going to see a car.
* Note : The car had about 110k miles on it.
* From the Kelly BB :
* Suggested Retail = $6330
* The Kelley BB seems consistently on the higher side
