Ok, now I recall that. I get a "page not found" from Offroad Gorilla, but Google still has the cached version of that page for the 7029 (Frontier/Pathfinder/Xterra version).smj999smj wrote:I had heard about it and was directed to Offroad Gorilla's site almost a year ago and they had a notice that due to problems, they were no longer selling them. Stillen also stopped selling them around the same time.
I appreciate in depth answer.

They are actually Pentosin Pentafrost A2 (green) and Pentafrost A3 (blue), respectively. You can find the Pentosin in Autozone stores and some other part stores, as well as from Rockauto.com. The green coolant is sold as a concentrate (mix with distilled water) and the blue is sold only as a pre-mix. Green has an initial service interval of 90,000 miles and then at 60,000 mile intervals, thereafter. Blue is actually good for up to 135,000 miles, but Nissan calls for 105,000 mile intervals. They are completely cross-compatible, however, service life of the blue coolant will be lessened as per the amount of green coolant in it. It's hard to get all of the coolant out of the system, especially if you have rear heat. Unless you have some severe under-servicing issues with the coolant system, I wouldn't recommend using a chemical flush. If you replace the radiator and just drain the system, you will replace about 2-gallons of coolant. That should be fine, however, if you want to get more out and are bit of a glutton for punishment, there is a drain on the passenger side of the block that's a pain to get to, IIRC. Zerex Asian Blue coolant is a pretty good aftermarket alternative for the Nissan blue, as well.
if you have 2011, you are most likely clear of any radiator problems. 2011 and 2012 years comes up around this forum quiet often and it looks like it's clear of pretty much all the bugs
