There's a u shaped hose against the firewall that has sprung a leak. It's way in the back of the engine compartment. Looks like I may have to take the hood off to get to it.

Anyone ever replaced this before?
Anyone have a link to a post?

Any help is appriciated!

I believe that is the heater hose you are talking about.

Check 8t8's rebuild thread, you might find info in it.

I found this photo in another thread...
I doesn't go to the heater core. It's the one in the middle.

those two hoses loose in that photo are for the heater. The one that wraps around goes into the heater control valve. In the top photo that particular hose is actually missing.

There are 3 hoses in that photo...
the 2 on the left are for the heater core.

The "U" shaped one on the right is the one I mentioned in the original post.

I'm hoping someone can tell me how to replace it because there is VERY limited access to that area with the engine in the vehicle.

Thanks again!

if you are talking about that U-shaped hose at that bank of sensors.......yeh...that's probably a pain in the acorns

take off the hood....get a good look. plenum can come off with plenty of effort

xxxtreme22r

ok when you said one in the middle yeah I saw the u-shaped one on the end and took that heater one as the one in the middle.

thefreqofnature

Yup! Thats the one.

yeah...not sure if that one is leaking on my son's too.

noted a water leak just a short time ago......can't find it. but seeing as ow i had a small hose leak on my truck, i know t gets worse when it's running and at pressure. we will see.

plenum is basically like 6 bolts and 2 nuts plus 4 zillion hoses. i will avoid this hose if i can.

That little guy gets cooked by the exhaust crossover and leaks on a lot of veezys. Taking the hood off is a good suggestion. You might avoid having to remove the plenum that way.

I replaced it when I changed the head gaskets; luckily it didn't leak before then...

Check out the fuel pulsation damper while you're there to make sure it's not dripping fuel when ignition on (but not started) and FP jumped to +B in the check connector; that leaks on a lot of veezys too, and is an extreme fire hazard.

I don't know about others, but I used my hands to take it off.....hahaha

But seriously, it's a pain to do. It CAN be done without removing the intake manifold, with a set of LOOOOOOOONG needle nose pliers. But beware! Don't break that little evap/coolant valve back there like I did. It's costly.

Since it's gonna be replaced. Pull the hood. Buy some realllllllllly long needle nose plyers. Use the needle nose to pinch and move the clamps out of the way. Take a utility knife and gently split the ends of the hose and pull the hose off. Take care to not scratch the brass fittings with the knife. When you go to put the new hose on, smear some grease lighty on the inside of the hose ends. This helps with slipping the hose on.

It CAN be done without pulling the hood off. I just laid a towel on my intake manifold, and laid on top of it while pulling and cursing. It's a VERY tight fit though.

I pulled my hose off, and of course, the ends ripped off. But no matter, it's coming off either way. I then slipped the old ends off, and lightly wd-40'd the new hose ends, then slipped it on. Used long needle nose pliers to pop those clamps back on.

It was tough to do, and my wrists were cramping, but it saved me from removing the hood/intake manifold.

Removing the hood is easy. Intake plenum, not so much.

And THAT is why I love this site!!!



Thanks everyone!! My plan is to take it on this weekend. I have access to a loooooooong set of needle nose plyers/pliers but they have to be taken out of the wharehouse with a crane.

I make joke

Anyway, It seems pretty straight forward once the hood is off...thanks for the tip on the fuel pump, I'll check for a leak.

I'll post up anything that may help anyone else when I'm done.

haha....I had that same u shaped hose leak on my 88 Runner also. I don't remember the hood being in the way as I never considered even taking it off. I just remember what a PITA it was to get my fingers in there to get the old one off....I used a long needle nose pliers also. I couldn't believe that Toyota would do that....but I did get it changed.

4 bolts o remove it and all of a sudden you have room to throw your elbows and 100% more light to help you see what you are doing. It's worth the extra ten minutes for the comfort.

thefreqofnature

That's no help...YOU are a master magician.

We are mear mortals

it can be done without removing the plenum or hood, just pray that both hose clamps are accessible from the sides
