substitute for toyota super long life coolant

It's not to mention that replacing a heater core is a nightmare - nothing like replacing a radiator, which is a walk in the park.Ĭar makers (or even the aftermarket coolant makers) will back-spec extended-life coolants for old cars but that's only because they don't care if a pre-1995 car has heater-core failure. It may take 100,000 miles but you may see the damage at one point. However, if you have an older car or some aftermarket part with copper/brass/lead, it's probably a very good idea to avoid 'universal' extended-life coolants, whether it's Prestone, Peak, Zerex, Toyota Super Long Life Pink, or whatever. If you have an aluminum cooling system, including the heater core, go with a 'universal' extended-life coolant. Results of industry standard tests of the new Toyota extended-life coolant now show a substantial weight loss (corrosion), both in a 50-50 mix and in a 33% coolant mixture (solder corrosion is much greater in this more diluted solution).' 'We have in previous articles pointed out that today's coolant inhibitor packages contain a small amount of copper-brass protection, but may provide little protection if a radiator is made with high-lead solder. In fact, a better statement is that no extended-life coolant is safe for copper/brass/lead. As far as I can infer, no universal extended-life coolant is safe for copper/brass/lead.

Well, again, be very wary of 'universal' extended-life coolants. In addition to the sae link, the Motormag link is one with a wealth of information regarding AF choices and ingredients today.Ĭhrysler switches to OAT antifreeze for longer service interval. And based on Honda and Toyota oem extended life AF formulas, much more so than sebacate. In any case, the only inhibitor the Asian AF's specifically avoid is 2eha, thus that's the one I would want to avoid if possible. And now Nissan and Hyundai/Kia have gone to an extended life AF too, that in greatest likelihood also uses sebacate, those too are back spec'd. Know for fact that Honda Type 2 is back spec'd for all Hondas, and I'd use it in any Honda before a Dex based 2eha AF. Seems curious though Toyota and Honda both using sebacate as an inhibitor if there was any kind of issue with metals or solder. Again very satisfied with my choice and results, and a very popular bitog universal AF option because of no 2eha and long life service interval with a complete flush.Īnd as the link indicates, Chrysler has now also gone to an OAT AF for longer life, but unlike GM and Ford it does not contain 2eha.

And PGL lists sodium benzoate as an/the active ingredient, it does not list sebacate. Personally no concerns about no P in PGL OAT. Phosphates are only bad if the antifreeze is mixed with very hard tap water such as found in Europe. Phosphates, unlike OAT, provide instant protection rather than thousands of miles to be effective. Is the propriety OAT sebacic acid? Chances are that it is and in that case it's bad for copper/brass/lead, despite the all makes/models claim.Īlso, it has no phosphates, which is something Toyota recommends having. That said, I've dumped the older and now expensive LL Red for Peak Global Lifetime concentrate. If the information regarding not using SLL pink in some older Toyotas is correct and authoritive then Toyota needs to be more specific regarding specific years, because afaik, though not the same formula Toyota has said the newer pink is completely compatible with the old red.

Same goes for the Euro AF formulas, no 2eha. Further, no Asian oem AF use any formula containing 2eha (Dex based), that would include any Dexcool or Dexclone universal formula.
