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.
Dealership quoted me $153. I think a jug of coolant runs around $25-$30 from Toyota.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.
trust me, it's very easy. ... open the drain from the driverside bottom of the radiator....
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.
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.
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 was going to buy Zerex its 14 bucks a gallon vs 22 from the dealer.
I broke down and wen to the dealer.
2 gallons of Toyota stuff and 2 gallons of honda stuff.
over 80 bucks in coolant.. WTF... U remember paying 8 bucks a gallon 10 years ago. It better last me another 10 years. :hurt:
