Hi y'all,

Sorry in advance for being such a newb! My Honda is a 93 Accord SE and I'm trying to figure out how to replace a hose that burst. It is the longer (of the two) hoses leading out of the bottom of the fast idle valve. I noticed my car was idling weird today and then saw the smoke and smelled sweet coolant burning on the engine so I pulled over and saw where the hose was spraying coolant. I can see the crack in the hose and I'm hoping to replace it myself to save money but i'm very new to DIY car repair and I can't seem to see where it ends up! It looks like it goes back into the engine somewhere underneath the fuel rail and intake manifold, generally. Tomorrow I will try jacking it up and looking underneath to see if I can find the end of the hose but I was thinking someone here might have some advice? Anyone ever have one of those hoses fail on them? Do you have to remove a bunch of stuff to replace it? Thanks everyone! First post so let me know if I'm leaving out info or if this has been addressed already elsewhere on here.

Disco'd, like the 70's.

 

Yes exactly! What's that part it's leading into? Is it possible to reach that from underneath the car? Thanks for this diagram it's really helpful!

 

that is the intake manifold flange near the thermostat hosing. I would go at this from the top.

I would also recommend all coolant hoses be replaced at the same time after having one burst. they all tend to degrade at a similar rate so if one has failed it's reasonable to assume the rest will do the same soon.

 

You may be able to replace all of them in a bundle. There are some aftermarket silicone ones which seem pretty complete, though maybe a little pricey.

 

Thanks so much y'all! Quick question: should I drain the coolant before attempting to remove this hose?

 

these small bypass hoses can be done without spilling too much coolant if you don't drain it. I have done it this way before but it's usually a case where i know the coolant is fresh (replaced recently) and i have a large drain pan to catch any small spills. I hose off the engine after I'm done.

but normally I drain when replacing a hose. good chance to get fresh coolant in the system.

 

Y'all thanks again. This is such an amazing resource for a newb like myself. I'll try and remember to follow up if I fix the hose!
