Coolant flush
I'm about to go over 100k miles and need to change some of these fluids out. I've never done a coolant flush, so does anyone have a write up (w/ pics preferably) or a youtube video on how to do this? TIA

Make sure you're using either Genuine Toyota SLLC (Super Long Life Coolant, aka "Toyota Pink") or one that is compatible (so far in my research only the Amsoil Coolant and Zerex Asian Formula match up to SLLC.)

I had the dealer do it. After the cost of the Toyota fluid it wasn't much more to just have them do the service.

How much did that run you? I need to do it on my Tacoma (same engine) and the 4runner in another 12k. Debating on whether I want to do it myself, or just pay the extra and have them do it.

Another good thing about the V8. . . sort of. Never have to personally flush the coolant as when it is time to do it it is also time to change the timing belt. that job with a new water pump is an automatic coolant flush.

Dealership quoted me $153. I think a jug of coolant runs around $25-$30 from Toyota.

trust me, it's very easy. all you have to do is buy the coolant from Toyota and open the drain from the driverside bottom of the radiator, get a vacuum cleaner that has a blowing capability, blow some air into the radiator cap to push the remaining liquids out thru the drain and refill with the SLLC from Toyota. you should be all set after that.
there's no need to flush but you can clean the white coolant tank.

Its easy to do, it just takes time having to let the engine warm up to start circulation so everything mixes well and goes through the engine/heater core, then letting it cool of to drain. A piece of tubing on the radiator drain to direct flow into whatever container your using makes things a lot cleaner. I plan on switching to AMSOIL coolant when I flush mine again, I have a dealer account and would be happy to help out.

I did it by the book, draining the petcock at the bottom of the radiator as well as on each side of the block. It wasn't difficult other than getting to those side petcocks through the wheel wells. Do yourself a big favor and get a two or three foot ratchet extension. I went ghetto and put several one foot and six inchers together and that was tedious to mate up to the drain bolt.

For a flush its easier to pull the thermostat. To remove and flush fluid from the block. Empty radiator, reinstall thermostat (I always put a new one in), then put half the systems capacity of pure undiluted Toyota antifreeze in and top off with water. Run engine untill thermostat opens and add more water if needed. When done fill reservoir to high mark with 50/50.

Nothing every goes quite right for me. The plastic drain broke while I was turning it with my fingers to loosen it. It was not too hard to remove it in several pieces with tools after that.
Took a few days for the Toyota dealer to get me one on back order...
be extra careful with it

This is actually slightly misleading as Toyota SLLC only comes in pre-mixed 50/50 (and I believe 60/40 for climates such as Canada.) There is no need to dilute the coolant; additionally Toyota LLC (or Toyota Red) is a different, older spec of coolant and diluting it does not equal "Toyota Pink" coolant.
Other than that, the information is correct and a good way to do it.
On a side note, first service is at 10yr/100k, following services for coolant are 5yr/50k after the first fluid service.
