how do i block off all the water lines unnecessary to cool the engine?
Toyota pickup 1989, 3.0 vze 6 cylinder. i have a water leak i cant find. its behind the block and i think under the intake manifold. i removed the plenum and still can not find it. i even stuck my phone on a selfie stick down there and still cant find it. how do i block off all unnecessary water lines so i can get back to work.
Could have saved yourself unnecessary labor by entering UV dye into the cooling system.
Did you even do a pressure test?
The u-shaped hose back at firewall could be the culprit
i removed the plenum and it is still leaking under the intake manifold somewhere, is there some way to only have the 2 radiator hoses cooling the engine? i just do not know where the places to cap so no water can leak anywhere. i live in a hot area and do not need the heater but i think the only place to plug the lines off are under the intake and i cant find the other one. any ideas? i am trying to do this without removing the intake as i need to go to work tomorrow.

No, their is not, that's the way the engine was designed, sounds like your in way over your head.
You can't just plug things up and expect it to run cool.
I wouldn't be surprised if one of your head gaskets is toast.
Maybe you should take it to a reputable mechanic.
The 3vze motor is not for the weary.
Yes, the coolant by-pass tube.
I have never seen one that was damaged although i wouldn't rule it out.
I have seen the nipple for the by-pass hose damaged and would not seal.
so the 2 hard tubes are the feed lines (and they are intertwined correct?) for coolant to the heater core, where does the heater water feed back into the engine? i just need to get it running temporarily until i have time to rebuild the engine in my garage.
