Flame trap replacement on Volvo 850.

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

Note that the oring often likes to take a hike as you do this job.

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.

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

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.

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.

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.
