i use prestone and on back it asid " NEVER add water" for the 50/50 antifreeze/coolant lol

thanks everybody for helping especially salimshah.

i made a appointment for oil change and i am going to buy the pink coolant from the toyota service.

total cost is

39.95 for oil change 49.95 if synthetic oil. plus 20$ more for pink toyota coolant

That was because the 50/50 has already come premixed for you. Half antifreeze and half distilled water. That you can dump right in to your overflow tank to top off at any time.

Sounds like you were doing OK, however, you did not know the why or how of the process.

Just an F.Y.I.. No timing belt change required on 2007 RX350 as it has a timing chain which does not need replacing.

Old thread.

Yes, I know already. Admitted as much on a different thread a year ago.

ok im a bit confused here i see some say red coolant i also read someone say pink
is toyota coolant different then another long life coolant like Dex-cool ?

i have 4 gallons of Prestone Dex-cool sitting in my garage and want to know if the TOyota Coolant for my 07 ES350 which i belive has teh same motor and cooling system as the RX here mentioned
so is Dex cool good to use or is it a special Toyota coolant it calls for ?

This is what it says in the 2007 RX350 Owner's Manual. Nothing specific about DEX-COOL or anything else:



Just check your containers to see if it meets those specs as I am not sure exactly which product you have and its date of production. Things can change over time. The Prestone site says:

Prestone® Antifreeze/Coolant is completely safe for use in both foreign and domestic vehicles. For those consumers who would feel more comfortable using a phosphate-free antifreeze, our Prestone® Extended Life 50/50 Antifreeze/Coolant is phosphate, silicate, and borate free. This coolant uses a special chemistry and technology that extends the life of the corrosion inhibitor package so that it lasts for five years or 150,000 miles (whichever comes first), and is safe for all cars and light trucks (old or new).
