Does anyone have a photo of either of the drain plugs on the block? Just for some reference of what it looks like.

 

It's like a nut with a nipple/hose barb beneath it

 

Hi Guys, thread OP here. So I did the coolant change over the weekend. Went to a local Toyota and got 2 gallons of EMO coolant for a total of $40 plus tax. All I did was drained the radiator and siphoned out the overflow reservoir. I used an empty 1 gallon milk jug and got exactly 1 gallon or 4 quarts out. I didn’t drain the engine blocks, too much work. I plan to do another drain and fill in about 35k to 40k. Love this baby and keeping it until the wheels fall off. I square if I ever get her to 500k, all I will ever buy is Toyota/Lexus . Thank you all for the input.

 

You're at 100k miles? If I were you I'd do 3 or 4 more of those because as you can see from the previous tables, you've only added about 40% new coolant.

 

Yep, am at 100K. I saw the tables the other guys posted. With 40% new coolant, it should last a while, about 30k to 40k, before I need to change again. This is how dealers service your vehicles as well. The don't drain out 100% of the fluids, whether it is transmission, axles, etc. That is why per our manual the service interval is shorter after after any fluid change compared to when new. Thanks.

 

100% agree with a drain and re-fill. Unless you're seeing discoloration or debris no need to flush and re-fill unless you just want to spend the extra money.

 

My maintenance schedule states 120mos/100k miles to replace the coolant and then replace every 60mos/50k miles thereafter. If I was to take it to the dealer to replace the coolant and they only drained the radiator I would feel like they were misleading me as they would only be replacing approx. 40%. I would expect that they'd drain the block too only leaving what's in the heater core.

I'm not saying only draining the radiator will lead to problems or is insufficient. I don't really know and you might only know if you had the old coolant analyzed but for me, i think I'll do more and what I might actually do is, depending on the difficulty of draining the block just drain the radiator at every oil change after I reach 100k miles.

 

Is there a bleeder valve on this engine?
I know the 2GR Fe V6 in the Camry has one

 

I don't know where it is on the 2GR-FSE, but I have changed coolant on the 2GR-FE and didn't need to use it. I just used a Lisle funnel and as far as I know it never had any air problems.

Where is the bleeder on the 2GF-Fe? Is it on the passenger side of the engine between the banks? There's something that looks like a bleeder valve there but I wasn't sure.

 

I would definitely second the Lisle Funnel, especially the newer version that's translucent. Very handy tool.
The toyota bleeder is a brass colored fitting located here: linky

 

Yep, that's what I was looking at.
