Hey guys. I'm a firm believer of changing the ATF regardless of it being called a lifetime fluid. I recently bought an 07 ES350 with around 75K miles and would like to do this via a drain and fill method (I'd probably screw it up if I tried to pull a cooler line).
1. Is it more or less than 1 quart when you drain the pan on this model? I realize it will be a ton of drain and fills to complete this, but I figured I'd just do a couple of quarts every weekend until I get most of the fluid changed out.
2. Is it really required to get the temp up to 104? I figure if I leave the replacement quart with the vehicle, they will both be the same temp and should be no harm no foul. But I did read a post about heat cycling in another RX forum and don't want to cause any damage.
3. Would I be able to use a gas siphon or something else to pull more fluid out of the drain area? I haven't pulled the fender plastic to view the area yet.
4. What size tubing do I need to connect to my funnel that's used to add fluid?
Thanks guys! I did a search and got some answers but was still left with these.
