the egr (exhaust gas recirculater) on my '00 chevy tracker has gone the way of the dinosaurs and i need it to pas emissions. the tracker is a chevy, '00, 4x4, 2.0 l, and has 178,000 on it. new parts are $327.19! and i cant do that. the part advanced auto parts quaterd me was part #egr1768 made by bwd. is there a list of modles that have the same part as i need or a part that will work and what it comes off of so i can find it at the yard

While I can't say specific to the 2.0l, the 1.6l 16v is known to have alot of egr related issues & throws the p0400 code at the drop of a hat. Mine threw it 3 weeks into owning it. The good news is, it's 95% a cleaning issue & not parts. I agree, for a simple vacuum actualted valve, the part is ABSURDLY expensive. On the 1.6 it's almost always a matter of cleaning a tube & port into the intake. I cleaned the tube & port & it hasn't thrown the code since!! I know this won't be the same setup as the 2l but, are you sure the valve itself is actually bad? Ie, is the diaphram worn/cracked/stuck or otherwise damaged? You can test this with a hand vacuum pump on the 1.6. I'd check & clean the path that the exhaust actually travels through before throwing parts at it, good chance it's just clogged up & won't need anything but cleaning.
As far as used parts, you could look for one from a 1.8l or 2l from say an Esteem or Swift, or a 1.8 Sidekick Sport... I believe they are same block & theres a good chance alot of parts would interchange... but don't quote me on that. Hth.

Goto the RockAuto website and use their catalogue to look up the part, click on the part and you should get a list of the other vehicles it is used on.

how would i go about cleaning it if it would work that would be awesome. also when i went running around to the parts yards around here it stopped throwing the code (i.e. the service engine light went off) eny clue as to why? and how do i check to see if the diaphragm is  worn, cracked or stuck.
i realy need this fixed and on the cheep just a line cook in love with his tracker. i really cant afford to pay allot and would like to do all i can myself, i only payed $500 cash for the tracker and have problems paying 75% of the cost of the car on parts. other than this its been running great and have had no problems with it except for a some oil leaking but that's not a issue

I would expect a 2000 Tracker to be a stepper motor driven EGR, there is no diaphragm, check for poor electrical connections and clean out the passageway through the back of the head. The EGR valve is the same on most of the Suzuki models of that era.
