WD40 around the bolt... leave it for a minute, some hopefully will seep in.

Have you people heard of socket sets?? sheech.. that will be the easiest way to get it off.. even if the nut is stripped a fair amount, a socket will get it off most likely

May be better on a warmer day with the engine warm.. sump will expand slightly, making it easier to get out.

predator,

i thought u would want to do it when it was cold, so the bolt shrinks. not expands.

also i will try these methods of "pulling" the bolt off, however apparently (according to my dogdy mechanic) there is a plate behind the hole of the sump (for extra strength) and the plate might be spinning along with the plug and not just the plug itself. if that makes sense? That is why he is charging me 280 to get it fixed. cause he reckons he needs to take the sump off and re-weld these points for strength. does this make sense anyone?

ah a different problem to what I had, I couldn't get the bolt to turn, but your sump plug keeps turning... is that right?

also I found the bolt was an inbetween size, couldn't find a socket that fitted tightly, and by the look of it others had the same problem. but I might put a crush washer(non flat washer to prevent overtightening) on it again as they are only about $2.50 from nissan.

Well unless u are running some sort of weird aftermarket sump plug, its just standard! you're not using an imperial socket are you??

I believe its 12mm or 14mm but that is just from memory. There is nothing weird about it.

Try a longer spanner or extender to increase leverage..

yeah pretty much. 1stly the sump plug wouldn't loosen, then with my mates big biceps, he ended up loosing it up. its loose but not enought to take it off. Furthermore u cant tighten back up either. it just keeps on spinning. u can just fit a small screwdriver head between the head of the bolt and the sump.

any other suggestions?

The sump plug screws into a captive nut spot welded to the sump. If the plug turns both ways and does not come on or off, the nut or spot weld have broken or is stripped.Sorry sump off to fix if the nut is loose or you might be able to drill out and tap oversize if the nut is stripped.Get the plug out any way you can ( I have used a large screwdriver under the head of the plug while turning before) and then assess damage.

    • Hey y'all! I'm curious about how y'all go about widebodying your cars. I noticed that when running a square setup, my front wheels are a bit more tucked in than my rear wheels. Not by much, maybe 5-10mm. This leads me to wonder - when I widebody, should I use narrower front flares and wider rear flares? I found a set of 40mm rear flares that I really like, and was thinking of pairing them with some 18mm front flares, but I don't want the car to look strange. How have others done this? Note, I'm in a sedan. Thanks!
    • And if it was anything other than an auto tranny part, it might be a problem. But seeing as all auto trannies belong in the recycling bin, it's fine.
    • I have an R32 Fenix rad. It is good.
    • All the schemas I can see, indicate your typical setup of ATF 'cooler' (read: heat exchanger) in the bottom radiator tank..ie; https://nissan.epc-data.com/stagea/wgnc34/5413-rb25det/engine/214/ ...but I can prattle on a bit here. These trannies have a thermistor in the sump ~ the TCU reads this and 1. bumps the line pressure up when the ATF is 'cold' and 2. prevents the TC lockup clutch from operating, until the ATF comes up to minimum operating temp (keeps the ATF 'churning' through the TC so it heats up quicker) -- trigger point is around 55C. In these conditions, the engine coolant temperature rises faster than the ATF temperature, and also helps heat the ATF up, which is why it's best to think of the in radiator tank setup as a heat exchanger ; the heat can flow in both directions... ...with these trannies, the 'hot' ATF comes out the front banjo bolt, flows through the cooler/heat exchanger, and returns to the box  via the rear banjo bolt. This gets a mention, due to the wildly different opinions wrt running auto trans fluid coolers ~ do you bypass the in radiator tank altogether, or put the cooler inline with the in radiator tank system...and then, do you put the additional cooler before of after the in radiator tank system?... ....fact is the nominal engine operating temp (roughly 75C), happens to be the ideal temperature for the ATF used in these trannies as well (no surprises there), so for the in radiator tank system to actually 'cool' the ATF, the ATF temp has to be hotter than that...lets say 100C -- you've got 25C of 'excess' heat, (slowly) pumping into the 75C coolant. This part of the equation changes drastically, when you've got 100C ATF flowing through an air cooled radiator ; you can move a lot more excess heat, faster ~ it is possible to cool the ATF 'too much' as it were...(climate matters a lot)... ...in an 'ideal' setup, what you're really trying to control here, is flash heating of the ATF, primarily produced by the TC interface. In a perfect world, wrt auto trans oil cooling, you want a dedicated trans cooler with builtin thermostatic valving - they exist. These should be run inline and before the in radiator tank system ~ when 'cold' the valving bypasses the fin stack, allowing the ATF to flow direct to the in radiator tank heat exchanger, so it works 'as intended' with helping heat the ATF up. When 'hot' (iirc it was 50C threshold), the valving shuts forcing the ATF through the cooler fin stack, and onto the in radiator tank heat exchanger...and you sort of think of it as a 'thermal conditioner' of sorts...ie; if you did cool your ATF down to 65C, the coolant will add a little heat, otherwise it works as intended... ...the 'hot' ATF coming from the front bango bolt, is instantiated from the TC when in use, so all/any flash heated oil, flows to the fluid-to-air cooler first, and because of the greater heat differential, you can get rid of this heat fast. Just how big (BTU/h) this cooler needs to be to effectively dissipate this TC flash heat, is the charm...too many variables to discuss here, but I just wanted to point out the nitty-gritty of automatic trans fluid coolers ~ they're a different beastie to what most ppl think of when considering an 'oil cooler'... /3.5cents
