Hi.
I´m currently changing all of my vacuum lines in the engine room, and discovered that at least two
of the seven solenoids located under all the vacuum lines are broken/damaged.

Where can I find these in good condition, or even new if the price is acceptable?
I prefer to change all of them, now when the things are apart.

Best regards
Christoffer

You can get good used ones in the for sale section for almost nothing.

If you buy them new from a dealer they're well over $100 each - In that case your best bet is to call Ray @ malloy mazda

I'd recomend two sources.

For new, Ray and Malloy Mazda. See my recent comment here. I'm guessing that these are about $55 (US$) new. Hmm ... you'll need to account for shipping to Karlstad as well.

For used, patiently watch the 3rd gen for sale section as well as post in the want to buy section. You'll see the entire "rat's nest" show up for $100ish shipped. The rat's nest is the entire assembly that is holding the 7 solenoids. Usually the seller will toss in some of the check valves as well. I highly recommend that you go this route. You'll find that these solenoids go bad on a regular basis.

or, if you want to have supertransitioning and no more failing solenoids:

I suggest you also call the local junkyards to see if they have Mazdas. The solenoids on the rack are not unique to the FD, so these can be found in a variety of Mazdas.

What's better is that a used solenoid from any other car is much better than a used solenoid from an FD. The FD engine bay is just that hot.

Thanks for all answers!

I got an offer from an Ebay user, willing to send me 10 solenoids for $100 incl shipping to Sweden. All of them have the same part number, and he told me this:
"These parts # you gave me are all the same the only difference is 1 has an air filter on it where another part # does not..
if you want I can do 100.00 for 10 and I will take care of shipping.."
I did answer him that there must be a reason why they put different part nr on them?
I did get this answer:
"If you remove the little air filter on the solenoids are all the same and you can take this solenoid and move it anywhere.."

Can this really be true?

I've always interchanged the rat's nest solenoids and moved the filter without an issue.

I like dgeesaman's idea. The solenoids form a Mazda other than our FDs would definitely have less heat induced wear.

Take a look at this:
http://www.fd3s.net/vacuum_hose_replacement.html

If you learn how the system works it becomes fairly obvious that the solenoids all function in the same way. You can prove it with a 12V power source, vacuum pump and a vacuum gauge. For that matter you can just use a clean hose to blow through an un-energized solenoid and then the same solenoid that is powered.

Can't remember who I should give credit for the attached to. Maybe someone will point us to the site that I grabbed these from years ago.

Yes, the air filters can be removed and moved to another solenoid or a different location.
