Everything Wrong With A Nissan Murano 3.5 CVT (V6 Swap Part 1)


this is our old four Nissan Murano it’s got 150 mm kilometers on it so about 110,000 miles we bought it as is this is generally when I start looking at vehicles because they’ve depreciated so much now I can afford them my buddy bought this one so far to date with 150,000 K on it it’s had a new transmission at the CVT transmission because they were prone for problems the previous owner did that so we figured he’d get a good deal on this one to get a safety we have we had to replace the subframe because the evaporator leaks the air conditioning water right onto the subframe where it sits in the frame and it rots the frame out and now we’re replacing the engine because it’s got a loud knock head gas gone all the oil went through the exhaust screwed up the catalytic screwed up the o2 sensors and we’re gonna have to pull this engine out now as it won’t be too bad of a job because it’s been taken apart so many times that all the bolts should come out nice and easy but what we’re going to have to do is take the hood off bring the fluids disconnect the drive shaft going to the back and see if we can get this air conditioning off without draining all the air conditioning and then we’re going to take this cowling off the best the better hoist to do a job like this is a to post hoist because you can take the whole body and lift the whole car off of the subframe I work on a lot of trucks so I’ve got a drive-on hoist because it’s much quicker to get the trucks in the air so I do have a crane so what we’re going to have to do is drop the subframe down onto the hoist and then take all this plastic off and generally I go on the strut towers and with my crane I pick the car up and I roll the car backwards and leave the engine sitting there then one once we got at the engine we could pull the engine off the transmission and the transfer case and then we’ve got another one from the Wreckers here with 112,000 on it so it should be a good 40,000 k before that one blows up sana Moreno here we’ve taken the cover off the top now I can get out my strut bolts I’m going to put a chain around here and I’m going to lift the body off body probably can’t handle being lifted from here with the engine still attached but with no weight on it there’s no no problem lifting from the strut towers as long as the windshield still in after windshields out you might put some strain on the body we’ve disconnected our wire harness I generally don’t don’t mark anything because they only go on one spot if you manage to flip these two around and plug them in while you’re very impressive and at the same time you shouldn’t be a mechanic the wire harness is loose everything up top here now we can go underneath and we can disconnect everything from the bottom I’ve disconnected our coolant hoses and our fuel lines your mainline and your return line and here every there disconnect the battery of course that’s the second thing you do after you disconnect your or pull out your fuel pump fuse and then disconnect the battery and then put that fuse right back in again because otherwise you wonder why your car’s not starting when everything’s done so we’re going to lift it up we’re going to pull the tires off we’re going to disconnect our struts generally just two bolts on the struts unless Nissan does something stupid and then that’ll disconnect the top half of the car from the Tigers assembly we’re going to take our exhaust off and take our driveshaft off and then we’re gonna drop the subframe down so here we go I’ve got everything disconnected on the subframe the engine transmission but ready to pull them out the bottom this is where the hoist gets in the way though I got drive on hoist which is handy because it’s a tool bench but it’s not handy if you want to pull the body off and leave the subframe on the ground so I’ve got the the scissor jacks in the middle I’m gonna have to block up the car drop the buttons Jack’s down block them higher lift the car up so I can get the tractor and pull the subframe out from the front it’s easy to do the torque converter bolts when it’s all together yet it’s easy to turn the engine and out of them when you’re working underneath it so do that first as you’re going grab every wire and hose and make sure there’s no tension on anything as you’re lifting the body up do it in two inch increments or so and every time you’re able to get at something like a hose you see a hose disconnected nice and easy to do now compared to when it’s behind the bumper later the wiring is a real pain because they use all these little squeeze together tabs that go through a hole and then the zip tie on the other end so you have to go on behind and squeeze these together and pull them out it’s the end of March I figured I could turn the heat off in the shop save some money and it’s freezing rain outside so it’s not nice working it makes a plastic cold and brittle and it snaps easier too so just keep that in mind but we’re gonna lift this up and take the tractor pull it out pull the engine out and start dressing our block that we got from the wreckers move everything over so they look identical and then pop everything back in again so here we go these are two of the three catalytic converters found on our Nissan Murano now a catalytic converters job is to take the exhaust gases and and get rid of the carbon monoxide as best as it’s can as it can it works best when it’s hot and it only does it doesn’t start working until it hits about 600 degrees Fahrenheit now the hotter it gets the better it works but the worse your oxides of nitrogen or your nos is it used to be that they check the exhaust gases coming out of the tailpipe when we did went for an emission test now they’re just plugging in the computer and really your engine light when it comes on all it’s telling you that there’s something wrong with the emissions there’s nothing with the drivability of the engine generally it’s all exhaust related so what you’ll find is an o2 sensor in front and behind the catalytics and it’s comparing the gases going in and coming out to seeing how well the catalytics are functioning now this one’s got all oil through it because we’ve had an engine issue so we have to replace that this catalyst is actually loose inside here and this one was probably setting a code before already so we’re going to run to the records and grab them because they’re pretty unique shape and unfortunately as soon as they go to the records they get scrapped only because this catalyst never disappears or stops working so the I’ve heard that there’s precious metals in there nobody cares about the precious metals they only care that they can take this catalyst out of this 10 year old catalytic converter and pop it in a brand new one again and hit the road the next day so they all get scrapped in the States we get a better price on it over the border there we’re going to take our o2 sensors out keep them for spares and you never know they’re expensive but maybe the customers up for he can replace them but we’ll go from there but that’s your breakdown on a catalytic converter this is our Murano engine transmission sitting on a stand as a stand I buzz together real quick for our GTO the whole body on what we worked on the frame but upside down it works as a decent engine stand um it’s not as simple of a job as I’d hoped you can’t just pull the subframe out and take the engine apart generally there’s a roll bell housing bolts you don’t do your torque converter pop the engine out probably one mount on the engine usually one or two on the transmission but this one there’s a bolt right back in here that I can’t see and look about the scrap engine I know there’s Fred’s there so what I’m thinking is transmission has to be split right down the middle here and then you can look inside this little adapter plate more that’s what it is and then you can get at this voltage so now the transmissions got to come apart probably all new oil the oil is probably thirty bucks a liter so yeah it’s a lot more involved so if you don’t have decent tools and decent knowledge of how the stuff works you’re in for a giant job way over your head another chop quoted them six grand for three new cats and a new used engine and I can see why because this is a giant pain in the neck I like putting my engine side-by-side so that I can move the stuff over from one to the other and make the engine look identical as it’s going now I’m looking at the bellhousing bolts here that hold the transmission in place and I can get a every bolt except for this one right here and it is actually blocked by the transmission so I thought that I would have to split the transmission right here to be able to get the bolt there now instead I drilled a hole into my engine because it’s scrap anyway it wouldn’t hurt anything but I can actually see the threads on the other side of the hole there there’s no bolt in that spot so I thought I’d have to split the transmission here to get at that bolt I would have been pretty pissed off if I made it that far and realized that there’s no bolt in there I don’t know whether it’s Nissan’s policy to just put a bolt in every other hole but what led me to that was I’d have to split it here you can see a crack there and you can see that the the molding comes out there’s a bolt here now it took started off and I could feel the head of the bolt and I wouldn’t be able to get that bolt out because it would hit the torque converter so obviously there’s a way to split this transmission from this engine without taking that bolt out and thankfully there was no bolt in there to begin with so now I can smile six hours less worth of work no chance of blowing up that transmission because I took it all apart so I’m gonna go have lunch and enjoy it because that was stressing me out for a little bit so this is the project that it’s most disassembled the engine is out from our front assembly pretty straightforward once I realized that it did not there was no bolt in this hole that was one I could not get at but the rest of the holes are easy enough to get out I had to disconnect my four-wheel drive or my reroute the transfer case going to the rear axle just so that I could get the oil pan around the corner here no big deal we always spill a little bit of coolant because it always ends up in the back corners there so I do always make sure the cats are outside that’s not a nice death and taste very sweet so they do like it so we’re going to clean up the mess we’re going to switch everything over from this old engine on to our new engine we’re going to put some new plugs in there move the air-conditioner our AC compressor alternator everything over and all that’s pretty straightforward you’ve been able to get this far with your project then you’ll be able to handle that we’ll take some more videos when we’re ready to put the back in the car again so here we go so follow a variety of projects that include conversions and repairs to anything from Ferraris to change us and check out the tape box my newest invention that’s coming to market and remember if you’re healthy
