So now that the Th400 swap is complete and working well. My water temps are not so happy and wonder if anyone has the same issue. I've been fighting my water temps for awhile now and cant get them to stay cool.
I use 50 parts distilled water and 50 parts Toyota Red, GTE mechanical fan 165*F thermostat. My AEM water temp sensor is on the upper water neck BUT my OEM temp needle stays dead in the middle. Cruising around town temps are around 195*F to 200*F which is not ideal but ok I guess. On the highway I would see temps get up to 212*F and if I do a small good pull, temps would reach 218* and that starts to be in the big danger zone.
I have the 5" intercooler core followed by a pusher fan on 1 trans cooler and 1 engine cooler followed by the A/C condenser than radiator with the mechanical fan pulling. I figured this would be a significant amount of air flowing through to make the water temps happy. but yet I see water temps getting wwwaayyy tttooo hhhooottt. And no I do not have any water or fluid leaks.
Anyone have any idea?

stock or aftermarket rad?
bleed the system?
look into getting a fan that blows 3000+ CFM. it will hold a piece a paper in front of your rad. you'll need to wire it directly to the battery along with a heavy duty marine relay.

After market aluminum radiator. The factory fan pulls 3800cfm, yes its bleed properly and no there are no bubbles in the system on start up or at all. A friend of mine with virtually the same setup is running temps at most at 185 reading off defi guages instead of AEM. He's also using the same exact rad, mechanical fan and engine cooler in the same spot.

Hmm....try maybe a new thermostat or one that allows it to open at a lower temp...or a quick thing to try is without a thermostat......
How old is the waterpump......
Do you have radiator shroud cover for the radiator?

thermostat was just replaced a few weeks ago 160*F, water pump is also fairly new. it was replaced when the motor came out maybe 5k or so miles go. Yes, radiator has the factory shroud.

Yes he actually has one and I'm going to be making one here some time this weekend or next week. The weird part is I had twin Efans before the stocker and it would stay at 190? But I also didn't have two oil coolers on the a/c condenser either.
Also, I hooked up the laptop to the AEM and the stock gauge reads lower than the external AEM temp gauge. Driving around town it would be between 185-190 where the external gauge is reading 200. On the highway 80 degree whether with a pull or two, stock gauge reads 195-198 and pretty much stays there where the external gauge reads 207-210 but would sometimes get up to 215 depending how long of a pull I do. So now I have no idea which readings I should really be watching or if the external sensor is on its way out?
Last night I did a coolant flush since I usually do a 50/50 mix with Toyota red. This time I'm trying a bottle of Water Wetter, 20% (1/2 gallon) Toyota Red and 80% (+/- 1.5 Gallons) Distilled water. With the Water Wetter, its suppose to help raise the boiling point of water where water is better at transferring heat. In my area there is no reason for me to use a 50% base cut of Red coolant. Its just enough to lubricate the system. Not sure what else to try.

Ok well I was looking over all aspects of the cooling system and I didn't think to test the clutch fan. when temps are higher I am able to stop the fan at idle and it seems to spin freely no matter what the temp is. Cold or hot. So no resistance in the clutch at all. This maybe the culprit for the higher temps I see. ****ty part is, I bought this gte fan/clutch from a SF member stating it's brand new ran for 400 miles or less. 
Ill be ordering a new clutch this afternoon and hope this is whats causing the higher coolant temps.
