Cooling System Bleeding for MKV Supra

[req]

There actually is a procedure, I figured it out a little while ago. Basically the same as the high temp except instead of turning the engine on you step on the gas peddle until you get the service procedure started message.

With that being said, do you thing it's still required to do the vacuum bleeding? I'm not 100% confident the line are clear of air?

some people say it worked doing the in car procedure which is setting climate to 84, hazards on, key in accessory mode, etc. i did that for like almost an hour and my temps were shit. you can try to do that and if it works then it works. if not you know to vaccum bleed. or vaccum fill. as long as you get the initial air in the system out then you should be fine. if that doesn't work you can run to harbor freight and get the maddox coolant bleeder and an air tank and return it when you're done. i luckily had my shop coolant bleeder when i did mine

No need to guess what the procedures are. I've posted them here before and now here again:

thats what i did initially but it didnt work for me. so i vacuum bled and did that procedure after. i dont understand how it can burp itself when the manifold is at the highest point but if it works it works

Did you just pour fluid in to initially fill? I use a vac tool to fill which GREATLY cuts down bleeding effort.

yea i initially just filled it normally but that didnt work so i just vacuum filled and bled it, then i did the in car procedure. i think you have to vacuum fill the mani at the very least since the manifold doesn't have the breather line like the prev gen b58. im assuming supraman was going to do the same thing as i did to fill the system

Yes,
open bleeder on overflow
fill overflow to top
close bleeder and replace overflow cap
close hood, make sure car is on ground (not on lift or jacks), apply parking brake
put car in diag mode (ht start button 3 times)
turn on low beam lights, and hazard lights
put heater control on max hot, blower on lowest
hold gas pedal down for 10 seconds (dont step on brake)
release gas pedal and start engine
instrument cluster displays message about service function starting
engine will rev up on its own for 11 minutes then return to idle
let engine cool all the way back off and check overflow tank

Anyone know how to bleed the hot side on the manual supra? My car cancels the procedure as soon as I turn it on.

I'll have to try in in the morning. Do you happen to close your door after your start it? Try leaving the door open during the process and dont close it.

I tried pretty much every which way. Door open/closes, hood up, hood down. Caps off, caps on.

can’t get it to bleed hotside

Have you tried pushing down the clutch pedal too, at the same time you hold down the accel pedal?

Good call, I haven't. I'll give that a shot today

Keep the hood closed, do the same steps, but you wont get the service function message when you hold thebgas pedal down until you start the car.
