I chose not to use the Toyota red because of price and availability. I recently flushed and refilled my wife’s 2002 Camry with the red coolant in it. Apparently the reason is that Honda has taken a public stance against coolants containing 2-EHA (2-ethylhexanoic acid). But they recommend their Zerex G-05, a HOAT, for Honda.
Zerex recommends their DexCool clone, Zerex ExtremeLife, for 1997 and up Toyotas. It is silicate-free but contains some phosphate, which provides some protection to the water pump from cavitation damage. Prior to 1997 Toyota used a conventional green coolant.įrom 1996 forward they began using a unique OAT coolant which does not use 2-EHA (2-ethylhexanoic acid) which is used in DexCool, the GM version of an OAT, and the European OAT formulae. Just had a service writer tell me there were two different Toyota red coolants, one regular and one long life, red and pink. This may have some true in it because the coolant I drained out of the Corolla seemed to be still clean after 5 years/60000 miles! However recently I have reading people saying that the red coolant is good for 5 years/50000 miles. I ended up replaced it with Prestone "all makes all models" when the guy at the dealer's parts department told me that the red one was only good for 2 years/30000 miles. They did have the red one in concentrated and pre-diluted. But the three Toyota dealers I inqured only had the pink coolant in pre-diluted 50/50. A couple of months back when I changed the coolant in the Corolla (yes, it was over-due), I was thinking of replacing it with the pink one so that I don't have to do it as often.
DOES TOYOTA SUPER LONG LIFE COOLANT HAVE SILICATES MANUAL
The Highlander owner's manual calls for coolant change at 120 months/120000 miles whereas the Corolla is substantially shorter. Both contain phosphates but they are different. I believe Toyota switched from the red to the pink around 2003. Toyota calls the red coolant "long life" and the pink coolant "super long life". The Corolla came with the red coolant and the Highlander came with the pink coolant. I have a 2000 Toyota Corolla and a 2004 Highlander.
