#PEAK GREEN COOLANT MANUAL#
Fred I had a 2007 A3 S-line, but with the 4 cyl (chipped) and a manual transmission.Availability of the new cooler is very low. Hopefully my order went through, as I have not yet received confirmation that it has been processed. Has anyone found a coolant that mixes happily with the Chrysler purple?Īs an aside, does it not occur to car companies that keeping an obviously defective part in production for 20 years does nothing for their rep? Seriously, they designed a whole car ffs, surely they could have been arsed enough to put their own aluminum oil filter/cooler in production? The failure rate on these is high enough to have spawned several aftermarket suppliers for the same bad product. This would not be an issue if the Chrysler dealer wasn't asking $50/jug for the OEM stuff. I see some coolants purporting to be useable in all models regardless of coolant, but the consequences of a screw-up can be dire, with the coolant basically turning into a jelly inside the motor. Unfortunately, it seems the OAT purple coolant used in this engine does not play well with some other coolants, including earlier orange HOAT coolants used in the same engine. Until it arrives, and until it warms up enough to do the job, I want to nurse it along, since it is more of a weepy leak than a gusher. I have ordered an all-metal Dorman unit to replace it and hopefully banish this particular demon (see what I did there) for good. The original (?) lasted a mere 90,000km, and the replacement I put in last year is already leaking. I still have some A3 blue left, as I use it for my Honda Odyssey.Well, as much as I like my Pentastar, I will readily admit the oil cooler design is a piece of crap.
Is there an advantage to using a newer chemistry coolant (for example the A3, which is recommended for the newer Nissans), and could this possibly extend my service interval if I were to do a complete flush and refill, making sure to fully rid the system of the old stuff? Pentofrost A2 is the appropriate coolant, but what is the difference between the red A1 (pre-2004 Toyota/Lexus/Scion), green A2 (Nissan, Kia, bunch of Japanese makes), blue A3 (Honda, 2009+ Subaru & Nissan) and the pink A4 (2004+ Toyota)? All claim to be a phosphated-OAT (P-HOAT) so the chemistry ought to be similar. That said, my research seems to indicate that Nissan used a green long-life coolant in these years, and recommends a 4 year / 60k mile service. Can get concentrate shipped to my door for not much more than a couple gallons of diluted stuff from the store. I use Pentofrost antifreeze in all my vehicles- have had good luck with it, and there's a Pentofrost product to fit nearly every application. I'm about to embark on the 250k service for my '96 Nissan Maxima and part of that service will include a coolant flush.
