there is a plug at the bottom of the rad ,turn this till the water-coolent pours out and system is empty,when filling back up make sure you have heaters turned to hot and on full blast,hope this helps
just run the car on idle with heaters on full blast and the rad cap off until bubbles stop appearing in the top of the rad.....no bleed nipples on a 4EFTE.
i'm going to be doing mine soon seed, i've got braided lines to fit....
I'm sure there was a post about it somewhere. I've never done it but it's fairly straightforward from what I recall....
Start with the caliper furthest away from the master cylinder, (Ensure you have enough fluid in the master cylinder to avoid pushing air into the system). Pump the pedal 10 times, losen the bleed nipple on the caliper and attach a clear bleed hose so you can see the fluid. Keep pumping untill the fluid is clear with no bubbles - then tighten the nipple whilst the foot is pressed on the pedal.
Repeat for each caliper working closer to the master cylinder, not forgetting to top it up.
