120k service questions

Postby Pegeru » Wed Mar 06, 2019 8:16 am

Hey guys,

appreciate some advice from those in the know. My 2011 2.5 Series 4 has hit the 120k mark and I think I'll attempt the service myself. Are the Haynes repair manuals sufficient for carrying out this service or is there a better source of information available online?

What are peoples thoughts on brands/types of suitable coolant, brake fluid and other drive-line fluids that need changing?

I'll have the auto-trans serviced by a specialist. Should I look at an aftermarket cooler at the same time or perhaps a by-pass? Reading the posts on contaminated trans fluid has me worried.

Any input, tips etc, welcomed.

Cheers,
Peter

Hi Pegeru,
I have written in the past about by-pass, look it up. If the 'specialist' says to do it, go elsewhere. Mine is 2013 with half the travel. Don't get the chance to go anywhere as we have gone OS to often lately but I do all the servicing since the warranty finished. I use CASTROL EDGE 5W-40 SN and change every 10K, more than a year with my current driving. Installed a catch can and electronic EGR block I have written about elsewhere. I have the Nisan service manual but don't think the link works any longer, any book will do, and some common sense. Check other posts, maybe there is a new link or Google?
I do diffs and transfer oil every 40K (the best you can get) and tranny every 50K. K&N air filter, fuel filter. If not done yet on yours, replace the shocks. Again, I have expressed my views on shocks, lifts and suspension in the past.
My battery is on constant watch as the caravan nearly killed it before I cut the green wire and now I only drive once a fortnight at best. Will get a new one if I have to or go on a bigger trip. I have a secondary AGM setup for the fridge at the back that can get me started in emergency. Will bo AGM under the bonnet as well, probably Banner from http://www.batteryvalue.com.au/
Also did the rear diff breather extension. Thinking of making some guards for the ABS sprocket sensors. A guy I know lost 4wd, in some harsh counry, doe to some grass wrapping there and taking the sensor out. They are very pricey (from stealereship) and hard to get in the middle of the beyond. Navara is the same. any knock to the rear ABS sensor and you are in 2wd only. What was wrong with the transfer gear leaver?
Check the brakes, measure the rotor thickness. I have posted those as well. Stopping is more important than going IMHO.

Happy motoring.

Thanks the information Darek. To date I have replaced shocks with Bilsteins, upgraded brakes, performed green wire mod and blanked EGR. The electronic version looks like a good option and one I'll consider after I install a catch can.
I had some luck today and located a manual so the fun can begin!
As far as the transmission cooler goes, I was under the impression that the unit was part of the radiator and the by-pass then removed cooling capacity. On closer inspection it appears to be a separate unit with the lines flowing through the radiator. So the by-pass it seems would only have an impact on bringing trans fluid up to temp more quickly not cooling. This could be an issue for me due to my location. What is your reasoning for opposing the by-pass?

Peter,
Have a look at this one viewtopic.php?f=20&t=9233, Transmission oil change. It's the coolant that keeps auto fluid at correct operating temperature (over 100 deg) when the air movement stops or is inadequate. Not sure about your conditions but I do drive, sometimes, in soft sand. 2nd gear low range and the foot down. Lost of hard work for very slow progress.
What are your thoughts on Bilsteins? I had a cheap source of EFS when I bought the car but they nothing special. Bilsteins suppose to be harsh. Some say you can tell what coin you run over by the jolt you get. I had a good run with Rancho on my old Jeep. They are now available in OZ for R51. I have written about shock here viewtopic.php?f=20&t=11594#p89770
This may also come useful one day viewtopic.php?f=20&t=11677
Flush the radiator and replace fluid should have been in my earlier reply. Good to see you found the manual.

Cheers

Thanks Darek, I think I now have enough understanding of the transmission cooler function to make a decision. Some interesting links. I did have a knock when hitting the odd bump on a couple of occasions, thankfully just a seatbelt buckle against plastic trim. No extra work at this point!
I do find the ride of the Pathie a bit harsh at times and perhaps it is just the Bilsteins. I'm not very experienced with these vehicles and had the Bilsteins fitted shortly after purchase. I didn't take enough notice of the ride with the old factory shocks at the time, as I was more concerned with the handling which was bordering on dangerous after hitting serious bumps. The handling is now hugely improved but as I mentioned I consider the ride to be a little harsh on bad roads. Whether it is the Bilsteins I cannot say for certain.

Hi Pegeru
With the 120k service, i have not seen the r51 books, but for other cars i have. If you are handy, i don't see any problems with following the haynes type books as they strip a car and rebuild it to make the books.
I generally do most service work ntself, then now and then get a good trusty shop to do a service. Idid this after my big central aus trip, its a lot easierto look for possible issues if its on a hoist.
With your trans question ,i have been told by various awesome reputation auto trans workshops, and the best 4 wheel drive shops around .. the same as you mentioned about the auto cooler lines in the ,which is to help bring trans up to temp quicker.
I have bypassed mine ,its been ages ,towes 2t camper no troubles. I trust the workshops i use ,if i don't do the work myself.
Each to their own, i know of someone who had their radiator/trans cooler fail ,it was a 550 v6 diesel, and $7000 repair bill...no thanks.
You know the saying, half of what you read is bull, the other half is sh!t
Talk to professionals.

I also replace brake fluid every three years.

Agree about the brake fluid,... unless you totally boil it like I have before. Then change it sooner. Not a good feeling down steep Hills with heavy camper and brake pedal on floor.

Thanks guys.

I had the transmission serviced, including a flush, as fluid wasn't in best condition and quite possibly never changed before. There is a noticable change in smoothness with shifting gears. I also had the transfer oil changed at same time. The workshop didn't perform bypass due to time restraints, but said there would be no problems with doing so. I haven't yet decided whether to or just have cooling system pressure tested on regular basis. At this point leaning towards the bypass to eliminate that niggling doubt
I've installed a Provent and changed oil and air filters, however, I've decided for peace of mind to have a mechanic perform the remaining tasks and give the vehicle a, hopefully, thorough examination, whilst up on the hoist. And yes, brake fluid will be changed.

Cheers,
Peter
