    Well, if it's not leaking oil externally and you are losing oil, it much be burning it. Hopefully they sent the head out to get resurfaced before they re-assembled the engine. Another possibility would be a clogged PCV system. If the PCV system is working properly, my next test would be a cylinder leakdown test.

    A genuine Nissan radiator should have "Nissan" molded into the top tank and a Nissan/Calsonic sticker on the top of the tank, several inches away from the radiator cap. If it doesn't look like a sticker was ever on the tank and you don't see "Nissan" molded into the top tank, it is likely an aftermarket replacement. Other clues that "may" exist to an aftermarket replacement include the radiator having an aftermarket cap and/or "worm-gear" radiator hose clamps instead of the factory "spring" or "constant tension" hose clamps.

    smj999smj, please ignore my previous question as I realized it was the condenser model number that I was seeing. Is the label for the oem radiator located on top like the condenser? I am currently at work for the next 16 hours and do not recall seeing a barcode or model number across the top of the radiator when I looked. Thanks again.

    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.
