Loosen the cylinder block drain cock plug

Hi. I recently started running through the fluids on my Taco and replacing what needs replacing. I got to coolant, which at 40k I am fully aware I do not need to do yet. BUT, I took a look at how to do it anyway and almost went through with it because I just happen to have some Amsoil coolant and I want to use it up to free up space in my cabinet.

I reached a point on confusion in looking at the service manual and quit for now.

Specifically, I cannot find where you are supposed to loosen the cylinder block drain cock plug and drain the cylinder block (*4 in the diagram below). Does this plug actually exist on the 2GR-FKS? I looked around on the forum and it doesn't seem like anybody else has posted on this yet. And there is definitely no cylinder block drain cock plug where indicated.

Insights much appreciated.

 

its probably under the valve cover, or hidden by the manifold.. just pull the bottom rad hose, drain, rinse with water, run 5 min, drain, and refill.. make sure engine gets to temp with the water in it, or it wont flush the heater core... you will never get all the fluid out... I worked ata mercedes/audi/volvo import shop and they would literally vac out as much coolant as possible (some vehicles it was only about 1-2 gallons... and then flush in new coolant to replace it.. that was considered a "coolant flush".. one of the many reasons I just could'nt do that job.. the dishonesty was rampant, no matter how reputable, or good the shop tried to be..

 

Thanks Scott. That's probably what I'll do then.

You ever throw a little vinegar in the distilled water you flush with? I'm pretty sure I just did that per the KTM factory service manual for my dirt bike. I dunno. The vinegar is supposed to achieve some kind of magic. I didn't question it then.

 

you could, you can also use distilled water as some claim that tap water has deposits in it, and can cause some funkiness in your engine due to calcification, or electrolysis... but I dont go for that BS.. especially if you are just using the water to flush before draining, and refill with the correct fluid.. the only thing I can say is that you make sure to use the correct approved fluid, as the incorrect type can cause seals to crack, dry, and you will wind up with a leak if you run it that way for an extended period.. i just use tap water.... if you have really crappy well water, then by all means use distilled water.. it is cheap enough...
