Coolant bleeding value

[ty**20]

Hey folks, does the 1MZFE engine have a coolant bleeding value anywhere on the engine? My hanes manual mention about this, but it never tell where is located. Anybody know where it is? Pics. will be awesome.

Also when I drain the coolant from the block. If I pour coolant into the cap at the upper hose is, will the coolant go straight to the block (when car is jacked at front). Or do coolant needs to go through the thermostat (in the lower hose) and into the block? Thanks,

This is the procedure from my Haynes manual (for a refill after a drain):

1. Close and tighten the radiator drain. Install and tighten the block drain plug.
2. Place the heater temperature control in the maximum heat position.
3. Slowly add new coolant (a 50/50 mixture of water and antifreeze) to the
radiator until it's full. Add coolant to the reservoir up to the lower mark.
4. Leave the radiator cap off and run the engine in a well-ventilated area until
the thermostat opens (coolant will begin flowing through the radiator and
the upper radiator hose will become hot.)
5. Turn the engine off and let it cool. Add more coolant mixture to bring the level
back up to the lip on the radiator filler neck.
6. Squeeze the upper radiator hose to expel air, then add more coolant mixture
if necessary. Replace the radiator cap.
7. Start the engine, allow it to reach normal operating temperature and check for
leaks.

There is no bleeder valve

Thanks. Glad to be informed about the no bleeder. I saw those steps in the book you listed. I was hoping to aviod all those steps by just refilling from the top cap. Guest not then. Just curious, will refilling from the top cap with the car tilt slide coolant down to the block?

It's better to fill the coolant up on a flat surface. To initially fill it up, you should be alright being at a tilt, but I am not sure about re-filling it and such. I've never done it like that so I dont really know if it will work or not? If you do the steps, set it flat and it looks like there is space between where the cap is and the radiator then I would suggest re-filling it to the top, and doing the last couple steps again

That was my main concern. If drained all the coolant out and refill and waited til the thermostat to open for coolant to flow in to the block, the engine would get near or even over heat from the insufficient amount of coolant inside. I think i will try that. Initially fill it up with a few qts from the tilt so it won't over heat quick, lower the car back to flat surface and finish off with the last couple steps from the haynes book to be safe.
