Hi,

I have two problems with my '97 850 Wagon, and hope some expert(s) can
help me. Thanx in advance.

1. I'm unable to adjust my right head light beam--that is, to raise the beam
higher (right now, it is pointing too low to ground to the point where
visibility is limited),
even thru I can adjust the left head light beam by turning the adjusting
clockwise/counter clockwise to raise or lower the beam, respectively. Is
there anyway to adjust the beam up without having to replace the entire
headlight assembly?

2. How often should I change my spark plugs. The maintenance states for
every 30K miles,
but I wonder if that is excessive. Also, what is the best spark plugs to
use for the Volvo 850.

The reflector is attached to the adjustment rods inside the headlight.
These can come unsnapped if someone is a little too aggressive changing
a bulb. Remove the cover for bulb replacement and see if the bulb and
lens are loose inside the housing. I was able to snap one back together
without taking the light off the car on a S70, which has somewhat larger
"bulb changing holes" than the 850.

Replace tt with t (twice!) and remove parentheses to email me directly.
(But I check the newsgroup more often than this email address.)
 
Upon reading your email, I removed the bulb, and discovered that prior owner
is using a generic light assembly because the internal is loose contrast to
the left
headlight assembly. This is the culprit of this problem.
 
Remember there are two adjustments one for sideways and one for up and down
on each lens as well I think theres one for high beam as well on mine with
high beam driving lights in the lens don't screw it too much as you need
little adjustment I use a garage door with lines on it to get my lens
focused correctly .All must be level the floor and the door as well as the
car to get it right
