92 22re leak
I just rebuilt my 22re engine and put it in my truck but didnt put a thermostat in it. I went and got it IM'd and then drove it around for about 500 miles and then it started leaking antifreeze. alot of antifreeze. I parked it and now just looking for answers. I put a new thermstat in and it built up alot of pressure between the ratiator and the thermostat. I checked to see if I put it in right and I did. so I drained the antifreeze and ran water throught the block and then the ratiator to see if there were any kind of blockages and the water ran freely. The antifreeze was leaking from somewhere in the back of the engine. I replaced a couple gaskets to see if that was the problem, just seemed like it was a waste of time. All I can think of it the water pump. But I dont want to rip into something that isnt the problem. If anyone has any ideas please let me know. Thank you.

Its probably just a heater line on the back of the engine leaking. We can't find the leak on your truck through words on the internet so your going to have to provide pics, or find it yourself.
Good luck!

It's normal for some pressure to build up between the t-stat and radiator as the coolant warms up. Water expands as it heats up. Remember that the system operates under about 14 PSI pressure once warmed up and that is held in by the radiator cap. Raising the pressure in the system causes the boiling point to raise.
The only things you have at the back of the engine that carry water are the heater piping and hoses. But you can't rule out a headgasket leak at the back of the engine allowing coolant to escape.

Yea t-stat is required for proper coolant pressure and engine temp and flow and all kinds of ggod stuff..... did you get OEM toyota t-stat? you should or one very close...... sure its coming from hte back of ur engine? if so.... check those heater lines and or possible head gasket...... you didn't go cheap'o on that in build did you? Hows your intake gasket look... could be leaking form there...... look more and possilbe pics would be sweet....

the intake gasket was soaked so that was one of the gaskets I replaced. I didn't go cheap on the rebuild and I took my time putting it all together. Had the same problem when I replaced that gasket. The reason I said the leak was coming from the back of the engine is because when its running if you look under the truck the leak is cming off the bell of the transmission. And the pressure between the t-stat and ratiator just seems like alot more then normal.

you can do it yourself with the right tool (pretty cheap), or a mechanic will do it for bugger all. It is just a hand pump with a gauge that screws to the radiator and you pump pressure into the system. The leak becomes obvious when there is a bit of pressure in there.

not running a t-stat won't hurt you new rebuild. Just take forever to warm up and cause you to get ty gas mileage as the EFI runs best a a curtain temp 190*. Another tell tell sign of a heater core is water/coolant in floor board, passenger side by the tranny hump. The in/out lines of the heater core have an o-ring to seal the copper elbow lines to the actual core. If you determine its coming from the heater check them as they are like a $1 repair over the $80 for a new core.
X2 on the pressure test.

I talked to a machine shop and they said they will pressure check the cooling system and find the leak. I am dropping it off tomorrow night and should get it back whn I get off work on thursday. Will let you all know what is wrong and maybe need more advice.

I got my truck back today and now have good news and bad news. Th good news is they did a pressure test and found the external leaks and they were just bad hose clamps. the bad news is I either have a blown head gasket or a crack in the head. it takes a minute to start and when it does it blows out white smoke for a few minutes and then goes clear. the guy said he did some sort of test to check the head or head gasket and it failed. and my oil pressure is on the low side but that could just be the gauge.
