Merry christmas guys,

I know this question its been asked a million times before, but, which coolant its the best for my 2000 AWD? How much coolant do I need to buy? 2 gals.?

Thanks

I think the basic answer is the red or pink Toyota/Lexus coolant. There is the red Toyota/lexus coolant that came with the 2000 RX. As I recall, you need 1 gallon of this and it is mixed 50/50 with distilled water (preferably). Then, there is the newer Toyota/Lexus pink long-life coolant that is pre-mixed and you need, as I recall, 2 gallons.

I have switched to the pink, but there are many who suggest staying with the red. I don't recall anyone having problems with either one. There are some other OK brands out there too, but I don't recall their names. Toyota dealers are going to be less expensive than Lexus dealers, from my experience.

In addition, I seem to recall that LexMex and others have added an additive like Red Line WaterWetter to improve the cooling ability of the coolant.

I suggest you stay with the red, purchase from a toyota dealer, good luck !

Actually, take a look at update procedure starting here, https://www.clublexus.com/forums/rx-...ant-diy-3.html at post 44.

What I do is now buy just one bottle of Toyota Red Coolant (3.785 liters) and one bottle of Redline WaterWetter (you can use Royal Purple Purple Ice, too), the rest is all water. That's not going to be quite 50/50, but when you consider that Toyota Red Coolant is like about $20 a bottle, you're talking in the end like 46% coolant+waterwetter and 54% water.

I just want to say thanks to Lexmex for his very detailed DYI on the coolant!

I completed it in less than 30min last night, the hardest part was getting to the 10mm noozles on the front and back of the engine block.

I picked up 1 gallon of toyota red coolant and 1 water wetter and 2 gallons of distilled water. Set the AC on HOT for 10min then drove around for 10min and the fluid was still at the Full line. Its interesting that the system circulated the red coolant back to the res. that I filled with just distilled water.

I do have one question, does the system have to be bleed to get any air bubbles out?

Lexmex

The answer is officially yes, but there's no bleeder on the reservoir. What I mentioned in my DIY is that over the next few days to monitor the level. I would even carry a jug of water with me and note every morning before I left for work and left to go home. I did the same in Mexico. The level in the reservoir might go down and you just have to add water if necessary. I had it happen to me in Mexico an no harm done.

I have 3/4 of a gallon of the distilled water sitting in my car just in case. Thanks for all your help and the DYI write ups!

Now onto the transfer case and tranny

Lexmex,
I am going DYI my engine coolant as you have shown. My question is you would recommend the 50/50 long life or the your method for my area of the country. I live in the Adirondacks of NY. I rarely have the very hot temperatures you get. This week it was 0 degrees some nights, but it does get to the 90's in the summer.

Thanks

Lexmex

Are you referring to the 50/50 long life Prestone or going 50% Toyota Red coolant and 50% water?

Dietz

I was thinking of doing it your way with the Toyota Red and the wetwetter, but would the Prestone be better in my climate?

I would personally stick with the Toyota Long Life (Pinkish red) coolant.

Definitely stick with the Toyota coolant,It`s awsome stuff!

Lexmex

Yeah, Kool Aid, that works.

And if you want to really go quicker, nothing will be quicker than using in your engine oil:

Sorry, I couldn't resist the above any longer, happy holidays everybody.
