[st202gt]

is there anyway of cleaning the egr without remove the entire unit.
Can i use seafoam and pour it through the intake vacum line near throttle.

Hey, just out of curiosity, how do you know when you should clean it? Are you getting some F'd up readings? Or you just want to clean it? Cuz I had no idea every 12k miles it should be replaced or at least checked. LOL Had my car for almost 4 years now and um...... Yeah...... I think I should at least check up on it. But just for the the sake of conversation, I thought I would ask.

dont know about of checking your egr every 12k... Unless the car is running REALLY rich/failing emissions then i dont see a reason to.

first thing that would happen is the car would throw a code. If its an obd II then all you need is a scanner to pull up the codes, otherwise you need to look up the obd I flash codes. Either way dont be misled, these codes are only guides. An egr code could point to a vacuum leak, a solenoid problem, or a hole in the dump tube ect.

If you do suspect that it is the egr, then one way to check is to remove it and see if the little piston inside still moves. This would also be a good time to check if the dump tube is clogged as well. If either the egr is stuck or the tube is clogged, then some gentle solvent like MAF cleaner will free/unclog the parts. I havent heard of cleaning the egr while its still on the car...and i dont think and significant amount of seafoam would be able to reach that far. Best bet is to remove it, not that hard anyway. anyway if that doesn't work, then you should look for something else that could be wrong, like the aforementioned vacuum leak. Only when everything else seems in order should you go out looking for a new egr.
