Can anyone point out to me where on the engine block the coolant drain plug is located on a 97 Tacoma 3.4l? I can't for the life of me find the damn thing and would like to do a complete flush of my cooling system.

Thanks

you mean on the radiator? if not you could always take out thermostat and drain more there. i think thats the lowest spot the coolant goes

No, I mean on the engine block. FSM shows a coolant drain on the radiator and one on the engine block on the passenger side. Can't locate it.

I will be changing the t-stat, so maybe I'll just drain it from there, but why is it so difficult to locate the engine block drain?

Here's a better pic of one. This is on a 2001 Taco, see the red arrow behind the motor mount:


Note on the 3.4 5VZFE there is only one on the passinger side, removing the thermostat drains the drivers side of the block.

Thank you! That is very helpful.
