Last Summer my wife and I picked up this car to be our second vehicle.
It drives like a dream, but there have been some maintenance issues to
deal with over time.

First of all, the heater core went. I managed to get that changed out on
my own with some online help from http://www.volvoclub.org.uk/faq/
HeaterCoreReplacement.htm. Of course, I couldn't get *all* of the screws
back in place, but everything seems to work well enough now.

Secondly, the engine service light. I've looked on the net for
information on this one and they show pictures that don't seem to match
my car. I read a post in this group that indicated that the reset is
under a rubber seal next to the speedometer - and indeed there it is. So
what do I do to reset it?

Thirdly, the parking brake cable wasn't up to my son reefing on it. I
bought a replacement and started to replace it but the bolts holding the
rear driver side caliper in place are pretty stuck - just put some wd40
or something in there to free it up or is there a better solution (no pun
intended, but there it is).

That's it for now, and TIA if you have any suggestions.

IIRC, you pop out the rubber plug, and push the button in and hold it
for several seconds with the ignition on and the light should go out.


WD40 is pretty worthless, you can get much better penetrating oils. I
like P'Blaster, seems to work well. I also frequently abuse wrenches by
slipping a length of iron pipe over the handle to get more leverage, or
you can do it right and pick up a long breaker bar. Make sure you're
turning the bolt in the correct direction too

Thanks. Just what I'm looking for. Ignition on, several seconds until
the light goes out.

I've got a breaker bar but I don't think it will fit in the gap available
- can't even fit a socket wrench in there, just regular flat wrenches -
so I'll look around for a piece of pipe and see if I can pick up some of
this P'Blaster stuff in town.

I also tried the "hold for a few seconds" method as suggested by James Sweet.
Nope... that only works on my old Ford Thunderbird. As I learned a few weeks
ago with *my* new-to-me 1990 740GL, the "Service" light interval is run by gears
inside the cluster, just like the trip odometer. To reset (asssuming yours is like mine,
and they haven't changed things just to make me look bad), you can't just push
it in (like I did) a couple of millimeters, expecting it to be like an electrical switch.
You have to push it that far just to contact the gears inside, then a much harder
push to spin the gears back to "zero". Considering you can't see the gears, it's
difficult to know how hard and how far to push. Once my gears decided to
cooperate, they let go so suddenly that I thought I had punched a hole through
the back of my instrument cluster, but luckily everything still works.

You can also hook a couple of wrenches together, just hook the box end
of one on the open end of the other and get more leverage that way. Are
you sure you're taking out the right bolts? It's been a while, but I
don't recall there being any that hard to access on the brakes.

out how to reset the "Service Engine" light. Somewhere on the web (I
hadn't found this list yet) I saw that you just pushed the button below
the speedometer.

I did just that and it worked, EXCEPT that I hadn't realized that it was
not, in fact, a button, but a plug that I was supposed to have removed.

As you can imagine, I still have a rubber plug stuck inside the
instrument glass, but it does still work. Someday I'll take the cover
off and get it out,but it doesn't seem to bother anything.

Best to all,

It's actually pretty easy to remove the cluster and take it apart. Just
be careful not to get fingerprints on the gauge faces or inside of the
window, it looks as bad as having something in there.

Thanks. I figured that out after some experimentation. Had a couple
screws hanging around and started with one that was too short and it
didn't reset no matter how long I held it in so I tried a longer one and
it reset pretty much immediately.

It's not super tight - just too tight to easily get a socket set or
breaker bar on it. Could probably fit with a low profile socket, but I
usually only buy those as singles for individual jobs. I think the main
problem is the bolts (two of them) are somewhat corroded and stuck to
their threads as a result.
