Hey, I want to flush the coolant in my gt4, and was wondering what coolant/anti freeze you guys are using in your gt4s or other cars...

Toyota Long Life Red.

^what he said. Best coolant you can put in your car hands down. Also makes it 1000 times easier to find coolants leaks. Go to your local toyota dealer and get a gallon or two of it. Its a bit pricier then aftermarket antifreeze but in my opinion well worth the price.

Use the Toyota LL Red. It is an organic based antifreeze and will work as intended in our cars.
The green stuff is too hard on the seals and the orange stuff gunks up like mad.

Stick with stock. :)

cool thanks for the info guys, really appreciate it...

what would be the best way to flush/clean rad and all??

I would venture that it is worth it to have a shop take care of it since they have proper permits and facilities for disposing of it. Just bring the coolant to them when you do.

yeah that's not a problem, my buddy is a mechanic and has a shop where i can give him all the old stuff...i just wanna know what would be the best way to clean the insides of the rad and all the piping ...

flush it with a flush kit, then keep running water through til it's clear, then fill it up with super red and distilled water. All the old stuff (including the water used to flush it) is usually taken back by any store that sells it (around here that's by law but YMMV).

The red stuff [LLC] doesn't gunk up so much, it's really the pink stuff [SLLC] that leaves crap when it leaks.

I am surprised nobody else uses G-05. This is the clear type (not good for finding leaks obviously) and it does not "gunk" at all from my experience. Though I never have used it without replacing it for more than a couple seasons. Water wetter and distilled water is what I use in the summer usually. They claim its better than coolant, I have had zero overheating issues with these combonations. Also you can retain some of the water wetter when u go to winter by adding pure G-05 to get the proper mixture at winter onset; not draining the radiator completely.

I ran the G-05 in my ST215. Never had a problem with it.
