Owner reviews for antifreeze

Prestone teal colored euro coolant has never failed me.

I just did this because I had to replace my thermostat. Has been fine for 1000 miles now, most of which were hard miles (I have a company car, so the LR3 either gets driven in stop and go city traffic, or off roaded, depending on the weekend). I used GM Dexcool. No issues.

I've always used the Pentosin equivalent in all my Volkswagens and Audis. Pentosin E/SF. Pentosin SF is G12 (pink) -2005, Pentosin E is G13 (violet) 2006 onwards. Safe to mix with factory fill, of course can always go to the dealer for coolant too. These are concentrate, so you do have to mix 50/50 with distilled water though

If it's inconvenient to go to the dealer, you can buy the correct coolant at NAPA, they carry Pentosin brand chemicals.

Comma Xstream G48 coolant is the correct spec if you want to save a couple bucks over BMW coolant.

Honestly, go with the premixed Subaru blue coolant. It has the correct additives and will not harm the engine.

I always keep a gallon on hand and only needed to top up small loss from summer driving in my previous Outback.

Sitting in the driveway and waiting for your coolant temps to go up is illegal here in Germany.

I use the purple peak G13 in mine - from autozone. Its actually more pinkish when it pours. Made sure to flush with distilled water before adding the new coolant just in case but its been fine in my car. Don’t overthink it!

Prestone does work, but Toyota uses RTV to seal the coolant passages between timing cover/thermostat housing and engine block. Prestone uses 2-EHA which has been shown to be aggressive on silicone, however it’s not uncommon to see leaks with the OE coolant that uses sebacic acid which is also a plasticizer. That said, I have a Sienna and LS430 that’s filled with Prestone, no coolant leaks… yet.

Do not use Prestone 50/50. It is technically compatible, but it is a different formulation. Using Prestone 50/50 will shorten your service intervals to 36,000 miles. Beyond 36,000 miles you will cause damage to occur to the seals.
