    APU Coolant Flange

    Hi There
    I think I upset my coolant flange at the back of the engine. I'm getting a coolant dribble on the bellhousing in that area after doing some work on the crank vent system.

    How can I be sure I order the right parts? Without going to a dealer? ECS doesn't support it as it is not US model.

    Any tips on doing this job on this engine?

    Try Imparts or HSY.

    Or maybe Tooley Imports in Sydney can post one up to you.

      They aren't expensive to buy here, I have bought them from ebay and HSY in the past.

        I've seen a few on ebay but can't figure out which design I need.

          Part number should be 058121132 and N90746901 for the o-ring.

          The local suppliers will be able to confirm it off your VIN.

          As for the job itself, you'll need to re-wire your brain to work back-to-front, have lots of patience, and small hands.

              Thanks Guys.
              It's in a bitch position. Will have to see if I can get a cam in there or something.
              I can't really have the car apart for that long at the moment...

                OK.
                So I replaced the coolant flange. Wasn't the hardest job ever (i.e. sump) and fixed that leak. I got the dual port one and it came with a plug in the second port. That leak is fixed. I gather I caused it be bumping the hard line while fixing the oil leaks.

                Anyway, now I have a coolant leak that appears to be on one of the hoses on the oil cooler. I removed the hose and cleaned up the rubber, no holes. And I checked the bore and cleaned up the barb. There was a lot of dry coolant on there. I re-installed the hose with new hose clamps but it looks to still be leaking.
                Do you think a new hose is the way to go, or am I looking at replacing the whole oil cooler?
                Any tips for new players for that job"?>

                TIA
