    I do mine down the driveway. At least 95% of it evaporates. The rest goes into the ashfault.
    Any that goes into the ground gets filtered through the earth and ate by bacteria.

    If you were dumping hundreds of gallons of it, that would be different. Just clean the EGR system
    and don't worry about it or let others give you a hard time about it.

    I did a quick wire brush job on the intake manifold port and the EGR pipe, and then I just took everything (EGR cooler, pipe, and intake manifold) to the car wash and hit it with soapy pressurized water. I have to say you shouldn't mess around with any other method. It was very easy. Took 10 maybe 15 minutes to get them all totally clean. Didn't have to do any soaking or use tons of nasty chemicals.

    The one thing I didnt take to the car wash was the EGR valve and the portion of pipe its bolted to. I will clean that with wire brush and small amounts of brake cleaner tomorrow. I tried to get the plastic EGR valve off the metal portion its bolted to and started to strip both the phillips screws. Not sure if I will be able to get it off so I will just brush around it.

    You CLEARED the cooler, you didn't CLEAN it. And the soap is a nasty chemical.
    The main thing is it's clear to let the exhaust pass through. But it will start sticking to the older
    built up exhaust that hasn't be cleaned off.

    So you are saying I need to soak it in oven cleaner or oxy-clean to ensure all the tiny remaining exhaust particles are removed from the stainless steel surface? Attached is a picture of how it looks now. When I look in one end a shine a bright light down the other from what I can tell the inside metal is uniformly this clean all the way through the radiator.

    It looks good! But it's where you can't see, along the edges where the pressure water
    couldn't reach. That's why the soaking... If you were in a rush, I'd say good enough.
    But since you aren't, might as well do the little extra work to get it like new.
    Plus, where you are able to see, is the only part. If you had a micro camera you could slide between
    the fins, you'd probably see the residue.

    You are probably right, its not 100% clean all the way through. I am going to call it good enough so this project can be done this weekend, actually I just finished reinstalling it. I'll just have to pull it off again in 50-70K and clean again.

    Okay I got the car all back together today, including installing the oil catch can. I have to say that reinstalling everything was way easier than taking apart. I still had some trouble with getting the bolt and gasget lined up at the bottom of the back of the EGR cooler but I got it done!

    Followed the manual for the coolant refill (I fully drained it before I started this process). That went well, glad I read it because otherwise I would have had no idea about the air bleed valve!

    Car started right up just like normal (i had heard other people say they had a really rough start first time they started after cleaning EGR system, but I didnt have that), left it to idle for a while in maint mode with heater on, and then drove it around for about 30 minutes. No check engine lights, no apparent problems - car sounds good. Yay!

    Final items on my list to complete are transaxle fluid change, inverter coolant change, and MAF sensor clean, but those are easy jobs and I can reassemble the cowling and wipers before I do those.

    Thanks to everyone on this forum for providing support and following along! Its much appreciated and would have been a lot more difficult without you.

    I am very happy for you! All the rest is easy. And next time it will go faster and easier.
    I'm glad it ran well for you right from the start. I think it runs a little rough for most people
    because some carb cleaner get into the cylinders when they clean out the imports on the head.

    When mine did it, I shut it off, waited a few second and started it again, then it ran normally.
    When it cools off, make sure you check the overflow tank for the coolant and top it off if it's low.
    You did change the oil/filter already?

    To be honest I skipped the intake cleaning this time - wasnt very dirty (there was certainly some gunk there, but its not like there was enough to clog anything). I had that specific worry that I'd push stuff into the cylinders or accidentally gunk up the fuel injectors. I will tackle this the next time.

    I also have learned since I got the intake manifold back on the car about the individual EGR ports. I didnt even inspect those or realize they were there - as I mentioned earlier my intake manifold wasnt super dirty, it looks like it had been replaced in the recall. But I do want to take the intake manifold off again maybe in a year or two to inspect those ports, make sure they are clean and also clean the intake holes on the engine block properly.

    I will certainly keep a close eye on coolant over next few days to make sure it has stabilized.

    I havn't done an oil change yet as the previous owner did his a few thousand kilometers ago. I'll wait a bit to do this.

    One question I have for all of you is I need to get the windshield replaced. Does the wiper assembly and cowling need to be removed for this job, or does new windshield just slide in under it all? Hoping I could save a few bucks in labour by bringing the car into a glass shop with all that removed since I still have it all off - not sure if it matters or not.

    Is it ok to leave wipers and cowl off if you're parked outside and it rains? Or to drive with it off (assuming it's not raining!)?

    you will put other lives in danger if it suddenly rains. Well that’s what I am told on here because I drive w/o wipers during non raining seasons :LOL:

    With them off there is a giant gap between the hood and the windshield where it would all dump into the engine bay.

    I have my car under a carport so I dont have to worry about moisture (which would be snow for us right now). I'd be a bit concerned about all the water from the windshield getting down into the engine bay, so I personally would not leave it parked outside or drive it during rain. It seems like there are a fair amount of electronics and wires down there that I'd be worried about getting wet. On the passenger side it looks like it might just fall on the exaust manifold, but on the drive side there are hybrid cables and other electronics.

    But I dont see the harm in driving the car with wipers/cowling off in nice weather. I've done it twice just to test drive the car so I could make sure there were no problems before I took the effort to reassemble (once after I reinstalled spark plugs, and then yesterday after I put back in EGR system) - just makes the engine sound a bit louder because all the engine noise isnt insulated by all that stuff. Also make sure that the fairly long wiper cable is secured somewhere (I closed it in my trunk lid).

    I do plan on getting all that stuff back on soon so I can drive the car in bad weather.

    Well, of course I mean "will water intrude and screw things up or will wind catch and screw things up" ;)

    You're probably fine with the intake because it had been replaced.
    You should put the wiper assembly back on. It's NOT hard to remove or replace.
    and only take about 10-20 minutes.

    If you have full coverage, replacing the windshield should not cost you anything.
    And the company will remove it and reinstall the wiper assembly.
    Check with your insurance company about it though. Rules/law are different state to state and
    country to country.

    I took mine off before the guy arrived. But he installed it. I didn't want him too because I don't want
    anyone working on my car. But he said he was required too. I didn't feel like arguing with him so I let him do it.
    But I watched to make sure he did it correctly.

    Interesting - however I purchased the vehicle with a big crack in the windshield. Doubt insurance will cover a replacement because it was pre-existing.

    Well, I imagine not then. :) Guess you could call the different places and ask them for a price
    if you pull that out..

    I have been sliding my cowl on and off for each work session, a block of wood on the rocker cover helps keep the cowl propped up so that the seal meets the bonnet aka hood

    Just about to do a transaxle fluid and I realized I forgot to buy drain plug gasgets from the dealership. Anyone have advice on how to purchase a transaxle drain plug gasget from the local auto parts store? Is there a standard size?

    I found them on amazon (part #90430-18008) but it is 30$ for a 10 pack. I dont need that many.

    You really don't need new ones. Just tighten both to whatever torque it says, I don't know what that is though.
    I just snug them up, they don't need to be super tight. I've done mine twice and still not leaking.

    You could get them for the next time though. :)
