    As far as what parts to purchase for either job, it's a matter of choice. You can never go wrong with genuine Nissan, but you will pay the cost. You can purchase from to save a little money. The aftermarket timing kits seem to be of decent quality for the most part, but vary in what they contain. If you want to do all of the chains and guides, an aftermarket kit might be the best way to go. Try for aftermarket parts. For front cover seals, I would stick with genuine Nissan. For the front cover sealant, I used permatex ultra grey rigid high-torque RTV silicone #82195 which costs about $20 for a tube that has plenty to do the cover; it's similar to the factory sealant and thicker than black or red RTV. It applies with a caulk gun.

    There was a TSB on the issue. Nissan has updated upper chain tensioner "feet" and chains, along with a list of seals needed for the front cover. It's a pretty expensive job in the shop, usually starting around $1200 and going up if you take it the extra step, replacing the primary chain, tensioner, guides, water pump, thermostat, etc. Of the four I've done, I haven't seen any guide where. I would, however, add to the job: replace the primary timing chain and tensioner, water pump and thermostat. I would also check the serpentine drive belt and tensioner. I got new foam seals for the radiator from Nissan; they aren't "necessary," but they did come from the factory for a reason, so I figured I mind as well replace them, too.

    There were issues with the VQ40DE upper timing chains on 05-08 model years. Some of the chains were stamped with worn tooling and caused sharp edges on the chain, which cut into the plastic tensioner "feet." This would create a whining noise from the front of the engine, which gets worse over time. I compare it to the noise a bad P/S pump would make, but there are YouTube vids that demonstrate the noise. If the timing chain is not noisy, there's no reason to replace it. If it "whines," however, it's time to replace them.

    This cooler is fully capable of providing enough cooler of the transmission oil under most conditions. It does not provide the benefit of warming the fluid, like the radiator's integral cooler does, however. If you do a lot of heavy towing, or live in an area that sees extremely cold temperatures, I would not recommend the "bypass method." The other way is to replace the radiator. Aftermarket radiators are pretty cheap for these vehicles, selling for well under $100 for "made in China" Ebay radiators. Many opt for the name brand "Spectra Premium" radiator, which is also made in China, but sells for around $125+/-. The updated radiator from Nissan goes for $450 online ($550 list) and to me is not worth the price. My $92 Ebay radiator has been working fine in my 06 Pathy for 3+ years; my 08 SE had the "bypass" done, without issues.

    Nissan also extended the warranty to 8-yrs/80000 miles on the radiator and subsequent damage, and a repair price cap of $2500 for those between 80001-90000 miles, and another price cap of $3500 for 90001-100000 miles.
    There are a couple of ways to prevent this from occurring. The cheapest way is called the "bypass method." All of the affected vehicles that were built in North America come equipped with an auxiliary trans oil cooler located in front of the A/C condenser (I'm almost positive that the 2wd models had it as well, but you may want to check to be sure). On 05-07 models, it's simply a matter of of re-routing the trans cooler hoses so that the trans oil uses only the auxiliary cooler and "bypasses" the integral cooler inside the radiator.

    Sorry it took so long to get back to you; I've been a little busy at work.
    1) 05-10 Nissan Pathfinders/Frontiers/Xterras with automatic transmissions have had issues with the seal in the transmission oil cooler (located inside the lower tank of the radiator) failing and causing engine coolant & automatic transmission fluid cross-contamination, which often causes a strawberry milkshake looking mess inside the transmission and ruins the trans. 05-07 models are particularly prone. Original radiators will have a sticker on the top tank with the part #'s 21460-EA215 or 21460-EA265. These were later replaced by 21460-9CA2E, but some of these have also had the coolers fail. It seems somewhere in that part #'s range, Calsonic, who is owned by and makes the radiators for Nissan, corrected the issue.

    2nd ?...

    2. Timing chain. About 5 years ago the dealership said i needed to replace timing chain guides. I am guessing they said this based on milage and that they didn't actually take all the time it would take to open it up and visually see that they needed replaced! This is another item that I am paranoid about and figure since we will be in there doing this radiator thing, we should grab this too. Especially since my miles are so high now. So again, same question...what should I buy? Just the guides and the chains? the whole kit? Where is best place to buy?

    Hoping you can help on 2 ?'s ... oops, it said my typing has too many characters. I will post 2nd ? separately :)

    trans/radia. 05 Frontier 4X2 CC Se. 146K mi. Always kept up on the maintenance, until about 75K, then I only did oil changes. Never major problems. Last 3 oil changes, dealership buggin' me about doing 120K service...for $900! Looked it up & decided the husband & I can do ourselves. In research I can across this tranny problem that people are having & now i am SUPER paranoid it will happen. Want to do something now to prevent it. I see after reading all over internet that I need to replace radiator & then put a trans cooler on the outside. bypass the radiator somehow. At this point my brain is overwhelmed with information,since I am not an actual mechanic. (note: I know I can do it, I am mechanically inclined & super interested in doing this myself!). just need some specific advice on how to do it & where to buy the CORRECT parts, & which specify parts to buy.

    By your symptoms, it sounds like a bad distributor. When it stalls and won't start, check for lack of spark to the plugs. If there's no spark, I would replace the distributor assy., preferably a quality unit like a genuine Nissan or Hitachi. Since you are leaking oil past the shaft seal into the distributor, you really need a new distributor, anyway.

    Hi I have a 91 nissan sentra classic 4 door with a ga16de engine. My car would start fine and drive around for about 20 min and then all of a sudden it won't accelerate past 2500 RPM. Knowing its the MAF I switched it out for a friends OEM MAF and drove it around for a bit and all seemed well until it did it again. The car would jerk and bog down till it stalls , I have to wait about an hour till it cools and starts back up again and the whole process repeats itself. It's throwing code 12 (Air flow meter) but I know its working well. Is the TPS and throttle body part of the air flow meter code? Could it be wiring? It only does this when the engine gets to operating temperature. When I looked at the distributor I found oil and black residue in the cap and the rubber gasket was pretty much gone. I also changed fuel filter and pump. I did a whole engine tune up but idk whats the problem. Please help me. I just want to be able to drive this car :(
