anyone have trouble with the hose attached to the upper coolant neck nipple?

 

when you say trouble, what do you mean? trouble removing it?

 

I've pin pointed that its leaking but never heard of it having issues. Looking at the diagram, I don't know where the upper part of the hose connects.

 

can I just clamp it off for now?

 

naw...i dont think clamping it down is a good thing...My assumption is it goes to the heater core. I can't see what else is going on in the diagram.

 

bought the hose today from the dealer, about $20

 

I had problems with mine a few weeks ago. These are signs of when that hose is going bad
1. Obviously you will see signs of leaks on the floor.
2. when you are driving ur car and hit 75mph to 80mph on cruise or at a steddy drive your low coolant light will come on and when you let off that gas the light will go off. if you do check ur coolant reservior or the radiotor you will have full on everything. when this happens you are not crazy, you did see that light come on and went off. just replace it. And i don't know what hose you bought but that hose from lexus is $52.00, I'm a toyota technician and even with my discount with shipping and every I had to pay the $52.00. so it probably cost a few more bucks so double check that part you got cuz the hose in that pic looks like your brake booster hose. but my cost may just be out here i dont knwo... but replace the hose and you should be fine. do not just clamp it, i did the same thing while i was waiting for mine to get the my job site and it i went out on me on my way to work one morning.

 

To my surprise it was 20 bucks, the hose that I have flagged with the red arrow in the diagram above. Here's the kick in the pants, I had knee surgery last month. I can't stand for too long, I'm trying to figure out if I need to remove the entire intake or can I access it without doing so. Can't see the other end of the hose.

 

Thats weird, but lucky on the price and no you dont need to take of the entire intake off it aint fun but you can get to it. just get you a niddle nose pliers and head at it. you probably wont see back there so you might have to use your hand to feel it as you work on it. And make sure you get the clamp on all the way when you put it on. you dont wanna have to do it again

 

wait a min, it that hose under the intake? like does it goes from the bottom of the throttle body to the lower left hand side of the motor? Cuz I was actually thinking about the heatercore control valve hose behind you #6 spark plug and curves to the right to the control valve! thats why the price is so low lol, my bad on the misunderstanding man. im pretty sure you can get to it without taking off the intake. if not you might need to back off the bolts on the throttle body, move the throttle body back a little and proceed.

 

Will Do. Thanks for the tip
