    How to clean fuel injectors ?

    The fuel rail attachment cleaning for $100 is a really great option if that is truly available. Just as an aside, I did the diy hack fuel injector cleaning with a valve stem over the injector, a can of Berryman B12 and a 9V battery to open the injector. Since I have the intake off to deal...

    How to clean fuel injectors ?

    Agree with a higher concentration of in tank fuel cleaner. That is the fastest way to clean, and since it has already helped I would keep doing high concentration cleaner with every fuel add for the next couple of tanks and then switch to maintenance mode along with top tier gas.

    Yukon Denali XL (2011) - Radiator Replacement - Oil Cooler Line Issue

    Unfortunate indeed. It takes a long time to build a brand and short time to loose it. I can understand sourcing a second supplier, but using a part that doesn't fit seems worse than just simply back-ordering.

    Yukon Denali XL (2011) - Radiator Replacement - Oil Cooler Line Issue

    First I would check that the new fitting fits the oil line. Second, I am a little concerned that you don't have an OSC radiator. OSC claims to use the same plate cooler as stock, and that cooler and fitting don't look like the pictures from OSC.

    Yukon Denali XL (2011) - Radiator Replacement - Oil Cooler Line Issue

    It looks to me like the taper high point is fully past the chamfered edge, so it isn't binding on the taper. However, it is possible that the slot cutout for the clip has a large burr which is catching on the taper, but the side shot closeup shows the back edge of the cutout and it looks very...

    And for the taper, I see .6530" ID on the fitting and for the OD on the pipe, it is ~.6485 +/- .0005. So even more clearance for the taper.

    Yukon Denali XL (2011) - Radiator Replacement - Oil Cooler Line Issue

    Your oil lines look a little worn or possibly out of round. If there is a ridge at the edge of that shiny section, it may damage the seals unless you can scotchbrite it smooth. The fit is pretty tite, but if the pipe is round it should fit. Maybe the OSC fitting is too tight, but that is...

    Yukon Denali XL (2011) - Radiator Replacement - Oil Cooler Line Issue

    Agreed, with a clean fitting and some surface oil, you should be able to insert it with the correct angle. The OSC 2370 is highly rated and supports the 'deeper' fitting. It just means that the alignment needs to be more accurate the further it goes in. The seal is flexible and won't really...
