so since the car is a 99 i've been replacing whatever i can when the money is right, i'm going to replace the upper and lower radiator hoses but i was having trouble finding the correct part# for the hoses under TB on acura oem. i was looking to replace all the hoses that run coolant under the throttle body area and also the air hoses that connect to the TB as well. if someone can help out with part#'s, i only have internet at work as am moving but cannot stay on here searching for the info i need. any help is greatly appreciated.

Are the hoses damaged or dry rotted? Leaks?

awesome jjashaa thank you very much exact ones i needed but messing one i think, its a thicker hose that attaches to engine right under the throttle body, i think it might be a heater hose but that one actually popped on the end so i cut it and put it back on but wanna replace completely as well as the ones you just showed in the diagram. you guys are awesome thanks.

i believe that is a heater hose if it goes towards the firewall.

I think you're talking about part 3 or 4 in the diagram:

ok so having a little trouble finding the rest of the hoses i need, if someone could please help. I'm trying to replace all the little lines that run coolant and the air lines that come from the TB. i have the 3 jjashaa posted above, thank you very much by the way. But i can't seem to link which hoses go to which from the OEM diagram. I still need a part# for the air hose that goes on the side of TB, i believe thats the only other hose i need to replace in there. I also believe theres two other bigger hoses that connect to the block but i'm not sure, but i would like to replace those as well. i appreciate the help guys, i have limited internet access since i'm moving, so trying to tackle what i can before moving expenses kick in.

Some of the misc. hoses can be matched up at most auto parts stores if ya can't get the "OEM" part.

I noticed today looking through the OEM catalog that the mount hoses go to a valve which shows as ELECTRONIC CONTROL MOUNT SOLENOID, do these go bad?? or can they be cleaned?? if these are bad would they cause the idle issue, seems to only happen once the car is warmed up pretty good. If i go to the store around the corner runs fine but once engine is at temp starts the idle issue.

It would be FAR more helpful if you could take pictures of the hoses you are looking to replace.

the above about the mounts hoses is somethng i noticed while looking for the hoses.
Here's the hoses i ordered.

Got my intake in today wow does that thing roar. was hoping that magically the idle issue would go away but still haven't replaced the lines that I ordered above as there at the in laws house so will get to that this weekend, cause I know I smell I little bit of coolant after a decent amount of driving.

BoriTL

So i got my hoses in yesterday and plan on installing them tonight. As i was installing the intake though had a question about the coolant lines, the lines that ran to the little radiator in the airbox i looped together but noticed the coolant in there was really dirty, i had changed it like a year ago. Coolant is suppose to be constantly running through the lines am i correct??? Also looks like i can remove that metal pipe in the front that has the air and coolant lines running to them. where did you guys route that coolant line too??

Also one of the coolant lines running to the airbox lines has a knuckle/filter looking thing on it, what is that for??

Last question, the throttle body has a gasket to it, when i take the throttle body off i believe theres a spacer thats attached to the throttle body, does that have a gasket to??

BoriTL

what the heck is a thermo valve for??? attached to the coolant line coming from throttle body. the thing right next to B1-1 on the picture on post#3

Thats for the heated induction system, inside the air box theres a small radiator.
It heats incoming air at temps below 27F for better gas mileage. 2000 and up never got this system.

I ended up just taking it out and looping the line from the engine to the TB.

My top and lower radiator hoses were super tight the other night after a decent drive, does that mean anything?? like I could hardly squeeze them tight.

3.2TLc

Have your rad hoses always been tight, even before the recent work ?
Is the coolant level staying up within the rad ? Try pressure checking the system.

BoriTL

Not as tight as they were, almost felt like they could explode. I think my radiator fan switch is going out, cause i was trying to bleed the radiator the other day and never heard the fan come on, but heard it come on in traffic yesterday. If it's malfunctioning would that cause the coolant smell i keep smelling, since i've replaced all the coolant hoses.

Also just to rant how stupid is honda to put a pipe that just slides into the back of the bypass behind the thermostat area, looks like it could move with the slightest of touch or movement of the engine.

My temp guage never worked since i've had the car and noticed last night that the guage has a piece of paper wedged into the back of the needle part, as if to leave it placed at the half way mark, so opening up soon hopefully removing the paper will make it work again, or the previous idiot broke it which would suck.
