Coolant flush issues on 2005 es330
Hello,
Question from a novice here. I just have a question about a recent coolant flush that was done on my 05 es330. . After the flushing the system with distilled water, I was only able to put in around 5 L of fresh coolant (Toyota) through the radiator cap. Is there a way to put more coolant into the system i.e. another port or a line which I can disconnect and pour in coolant for instance? Hopefully someone who knows the es330 system can help.
Thanks.

what is the total capacity of your system? on my '02, there are three locations that need to be used to drain the system, one at the radiator and two more on the engine block.

I went looking for the capacity when I did a flush. IIRC, it was 9.7 qts.
So after a few flushes (max heat), then:
A) drain the two block taps and radiator.
B) fill with 9.7qts X .60 of concentrated coolant.
C) top up with dH2O
D) run w/heater on and burp. Should fill overflow on it's own, but if not, fill it w/60/40 mix.
E) Check back a few days later to account for any more escaped air.

I never flushed mine, just did a drain and fill of the radiator a few yrs back, and then put in about 2 new gallons when I put a new thermostat in last fall. I just use the pink 50/50. (gotta do the brake fluid this summer with my friend: we did the old pump it up, open up bleeder, over and over the last time and it worked to a T.)

first thing to check would be that your heat was switched "on" and allowing coolant to flow to the heater core while filling the radiator back up. make sure its open, or you'll have large pockets of air in your lines and heater core.
when flushing my coolant, i'll put the front of the car up on ramps, then allow it to idle with the radiator cap off. you should then see some bubbles come up from inside the radiator. add coolant as needed as its idling. also, try squeezing some of your hoses leading to and from the radiator. that can help get air pockets out sometimes as well.
hope this helps!

Thanks all for the answers.
I wasn't able to find any drain blocks while looking underneath the front of my 05 ES330, however, think I was able to drain out all of the old coolant through the petcock especially after the di water flush. Believe the capacity is like 9.2-9.7 L and was only able to put back in like 5 L and that's what has me worried. Did the whole turn on heater to high (with defroster on) and drove it for a week now, haven't noticed a drop in coolant or a rise in temperature. But again, can't help thinking that there's something I missed since only 5 L went in.

There should be two drain ports on the engine, one on the front near the oil filter, and the other under neath above the passenger axle.
Total fluid capacity is if starting from a completely dry system, i.e. no coolant in the block, heater core, radiator or the coolant lines. Of course it would be very difficult to get all of it out, but at least draining the block will get rid of what's in the engine.
Here's what it looks like on the 1MZ but it should be similar on the 3MZ if I'm not mistaken:

They are mid-block beneath the exhaust manifolds. You can see them from underneath if you look around.
That's just the residual volume that was in the heater core, hoses, and block. That is normal. If you swapped about 50% of it, then you have refreshed your coolant substantially and can not worry about it for a few more years. You can just drain/fill the radiator periodically (say, every 2 years) and you will be good, without having to mess with the block taps or try to flush the heater core. Trying to totally flush the system is not absolutely necessary to keep it in top shape. Plenty of cars just get a radiator (not whole system) drain/fill every few years and then proceed to have the system work well for 40 or 50 years.
But again, can't help thinking that there's something I missed since only 5 L went in.
