I used one of those and it has held. I did switch to heavy duty worm drive hose clamps, after another member said the Toyota ones leaked with the new style T. I also used a garden hose barbed T from home depot while I was waiting on the dorman parts to come in. It was a pain to get to work h
But held up really well.

Awesome. I have bought two and I am switching out mine now. Thanks!
 
can some post the location of the T's and which is input and output?

might be modifying mine, and replacing them for a shower water heating system..

I don't think towing matters. The coolant temps aren't that different. My A/T temps and engine oil ran around 212F on our 2500 miles out to Maine and back last week, but engine coolant was 198-202F the whole time, even with ambient temps around 90F. That was towing in 4th or 5th gear. Ambient coolant temp when not towing is 196-198F for me.

That said any ideas I have about why some people experience this failure and others don't is pure speculation on my part. FWIW I've got 126k on my 2013 now and so far mine haven't given out (though my radiator got the dreaded crack around 76k miles).

Hi was curious what kind of equipment you are using to see the temperature data? Thanks

OBD Fusion and a generic ELM327 OBD2 port reader
 
just replaced my heater t's at 190k. One of them disintegrated upon removal and chunks had to be dug out of the hoses and one showed signs of coolant leaking. I like to think 190k mi is just about enough time for them to be replaced. sorry i dont have any pictures
