I have a 1996 Volvo 850 wagon (no turbo). I am new at servicing my new old
Volvo. What are the tricks, precautions in changing the flame trap. Volvo
parts department suggested I should clean my old flame trap filter instead
of buying a new one, which here in Canada costs $8.00. Is it wise to clean
and if so what to use. I am not afraid of disassembling, but reassembling. I
am inexperienced and have big hands, but I think I'm mechanically inclined
to do it myself.
My second project is changing fuel filter. Any suggestion would be welcome.

There's no downside to cleaning, except time. While you're cleaning the
flame trap, clean all associated hoses.

Mike thanks for your promt reply. I read many interesting posts from
you. I will buy O ring and flame trap filter from the dealer, clean and
reuse the old one next time. What should I use to clean it. I had the
procedure printed out from www.volvospeed.com but still wanted some
reassurance.
Where should I buy quality parts in Canada. US sites have very good
prices, but do we have any here.

There are special air intake cleaner solvents available in spray cans at
auto supply places designed for this. However, varsol or paint thinner
works, as do brake cleaner and carb cleaner.

I don't know any good online place in Canada. I get my parts from a
dealer if I can't get them through my friend's garage from one of his
wholesale suppliers.

If the flame-trap has never been cleaned on a 1996 850, the filter
is going to be really gummed up. Replace the flame-trap. Here's how
to do it:

You will find that the engine will perform better with a clean flame-trap.
Also, it is easy to do, so you can clean it once a year.

Bev thanks for reply. I will change it with a new o ring and filter. I
am an Volvo owner for only three months. I have all the repair bills
from the previous owner, but he was not mechanically inclined so
everything was being serviced at the dealer and then at general
mechanic. Some things might have been overlooked. I am changing things
for which I can not find bills and which are do to be serviced.
