hey guys, i drive a 94 ls400 and i was having a coolant leak issue and found that it was what i thought was a bad heater control valve. I replaced it while doing a coolant flush only to find out it was a hose.. i went to autozone hoping they would have it or at least something similar but, they didnt have it in their system. Me and the guy helping me couldnt figure out if it was a heater hose or a bypass hose.. but im hoping you guys could help me figure it out because i spent all day trying to seal something that doesnt want to be sealed.
If you cant tell, its the hose in middle of the picture.
Also while i was under the passenger side loosening up the valve i noticed this hose just hanging out like it doesnt have a job to do. I have no idea where it connects to or if its supposed just hang there.. heres a few pics of it..
so i replaced the hose i was asking about after i ordered the part from lexuspartsnow.com. i finished flushing my coolant and refilled it, drove it about 3minutes to the smokeshop for some cigarettes and noticed my temperature guage kept going and went all the way to the red line if not passed it. So i went back home turned off car and saw a thick cloud of smoke coming out from behind the driver side headlight.. pulled out the fender cover only to find coolant coming out and i have no idea where its coming from.. i dont know if this hose is the issue but i did follow it from the coolant resevoir and found my window washer fluid resevoir in put together at the bottom with what looks to be jb weld or something.. but the fluid that was leaking was reddish pink like the coolant and cant find the source of it.. everything that was in this area under the hose was covered in coolant.. is this the source of my leak?
Maybe you didn't bleed the air out well enough which will cause the coolant to boil, this pushes coolant out into the reservoir and then onto the ground.

that would cause it to over heat? And would.letting it drain more solve this issue?
Trapped air can cause an over heat. To do the job properly you need one of these "letting it drain" will make the problem worse and could cause engine damage.
