Bleeding the clutch is easy for some, but for others the engine bay isn’t a place they usually venture. This DIY should make it easy for just a single person to bleed their clutch. I believe this works for both the 1ZZGE and 2ZZGE engines. I strongly recommend you use this DIY in conjunction with adjusting your clutch pedal travel (which is not yet a DIY).
Things you will need:
Torque wrench (suggested)
3 feet of 1/4″ I.D. Clear Vinyl tubing ($2.50/10 feet at Lowes)
DOT 4 brake fluid (I’m using Valvoline Syn Power High Performance Brake Fluid [Dry Boiling point = 500 F])
Step one: Create your waste hydraulic fluid container as the picture suggests. Make sure the end of the vinyl tubing is cut at a 90 degree angle for the best seal when on the bleed valve.
Step two: Locate the clutch bleed valve (see picture) and apply some Liquid Wrench (I used the spray). Let that soak in for a minute or two.
Step three: Using the 8mm socket and ratchet, loosen the bleed valve just enough to break it loose. Immediately attach the other end of the hose from your waste container to the bleed valve. Use the 8mm wrench and open the bleed valve a little more until fluid trickles into the hose.
Step four: Open up your brake fluid reservoir and get your new brake fluid ready. If your vinyl waste hose is long enough, set your waste container in your engine bay so you can see it from inside your car.
Step five: Manually pump your clutch pedal with your hands (it will not return by itself) as many times as you feel necessary, keeping an eye on the fluid level in your brake reservoir. Observe the color of fluid coming from the hose. Is it dark or frothy? If you want to completely replace your hydraulic fluid, continue adding new brake fluid and pumping your clutch until the fluid coming out is clear (this may take awhile).
Step six: Take the 8mm wrench and tighten the bleed valve. Remove the hose, being careful not to spill fluid on your car. Use the 8mm socket to snuggly tighten the bleed valve, or use the torque wrench to tighten it to 74 in-lb or 6.2 ft-lb (From: Toyota Repair Manual).
Step seven: Wipe up excess fluid with paper towels, and top-off brake fluid reservoir.
Step eight: Take your car for a test drive; it should shift much more smoothly!
