Nissan Pathfinder R51 (2005-2012) Questions & Answers

Sorry, can’t answer your question as my pathfinder is not that old and mine is a hybrid. My car is nearly 5 years old and the only problem I have had was when we returned from holidays and my battery was flat, that affected the electronics a bit but it was still drivable and Nissan reset the problem free of charge.

Yep. Nearly always a cracked head. You can get the coolant tested in your radiator for exhaust gases, they overpressurise the exhaust system. Heaps of stuff on the net about it, especially under D40 Navara or YD25

Yes. Unfortunately it's the symptoms of a cracked head, they are famous for it.
You can get your fluid sampled in your rad to confirm. A head is about $1300 plus labpr if that's your only issue but they can crack cylinders too.
You could try a liquid head repair then drain aftet a month and replace with evans waterless coolant to reduce system pressure then drive it til it goes bang. Search d40 yd25 issues.

Thanks for the info, I actually had the head replaced the first time I had this issue. I couldn’t imagine that would be the cause again right? Had the liquids tested and they’re good. I’m at a loss at this point unless there might be something else?

It would be From the A/C

Had the same issue but fixed it. It is likely an A/C issue where the water from the condenser doesn't quite go out the tube that you can see in the engine bay. I had to add another inch of tubing so the water did not run back into the passenger foot well. Easy fix.

Might Come from the whiper fluid hose, har the same problem with mine. Bad to bend lut the rubber floor in the front to fine the leak

Child lock?

I purchased a2006 Off Road edition Pathfinder in fall of 2017. Mirage was approx 150 000. I have had a few issues with it. Fuel pump went out, bushings are all worn, tensioner pulley is wobbling, paint is so so, runs great when it is running but now i've replaced front brakes and still have strange clicky squeal going on pretty loud. DVD entertainment sys works great, no broken door handles yet, fuel economy is around 16/17 mpg- it's a heavy vehicle, when I step on the bad- from a stop it sounds like a surge of power and air going through making it sound like a PC of big industrial equip, live the stereo and the seats are comfy! My passengers that I Uber often comment on how much they like it's looks and the roominess inside ( it can seat 8 max including driver but only 7 seat belts. I'm in love with it but am worried about it lasting very long unless I dump a bunch of money into it! Some say that Nissan uses quality parts and makes good vehicles, this is my first Nissan so guess i'll have to wait and see! Had a Mitsubishi Montero 4x4, loved it although quite a bit smaller, but it lasted 7 years second hand and motor ran great at 300,000 mi. when I retired it. The fuel pump went out for 3rd time for using aftermarket ones that were so much cheaper than OEM pump.

I have a r51 2.5 diesel 2008 that blew the headgasket at 138000km on our way to Flinder ranges.Took it to Adelaide. Had it fixed by replacing the cilynderhead with a new one. It runs better than ever.Took $3500 out of the wallet and that was including labor,check on turbo and new gaskets all around. Great job done by Matthew's Workshop in Cavan

I purchased a R51 2005 a week later the head and cylinder 2 went. Do yourself a favor and don't Flog It Off to somebody else cause otherwise they going to go through heartache getting it fixed like I did. I got my motor completely refurbished and it cost me 5 and a half grand. The previous owner a week before I purchased it replace the radiator and put Chemiweld right through it unbeknownst to me and that caused the snowballing effect throughout the whole motor

If you've got the same model as I have in my review you shouldn't be using seat covers at all as the will restrict your seat wrap around airbags in an accident.

The child lock button will probably be on. Look at the other rear door when it's open to see exactly where the child lock is, then slide a credit card in the jammed one and flick the child lock open. It'll then open from the inside and you can change the handle easily. I've changed a few on mine, they're notorious for breaking.

Thanks James - you were quite right but unfortunately I'd not thought of that because it had been inadvertently activated at some stage prior & have already been to the dealer to replace the handle - thanks anyway! :)

I purchased a genuine Nissan key for my 2005 Pathfinder off Ebay, but I was able to visit the seller's home to have it cut and programmed. $220 all up compared to a quote of $388 for a key and $100 for programming from a Sydney Nissan Dealer. Here's a tip, the guy cutting the key said the R51 Pathfinder ignition key barrel and the key have a tendency to wear. He pointed out the slight tapering wear on my original key. He cut the new key to match. If this isn't done, the new key would increase the rate of wear in the barrel.

Hi. I think you might find that it is the alternator. I just had mine replaced for the same noise.

On my Nissan is located on the passenger side, between the front and rear doors, at the bottom of the vehicle body. You must open the front door to see it.

When you say rear doors won't unlock via central lock/unlock... do you mean they remain locked when arrempting to OPEN the doors from the inside or from the outside of car?

From the outside. I have to open the front doors and reach through and pull open the back doors which is a pain with a newborn child and a 5 year old especially in the rain

I think it has something to do with how your key fob is programmed. Believe that it can be set up to unlock all or just front doors. Your owners manual will give instructions.

Ummm, more information please.

You have to use unleadfooted diesel.... lol. Drive slower.
