3.0 Coolant bypass hose rear intake
Anyone ever have the little 1/4" u-shaped coolant hose go bad in the back of the intake? Well I couldn't find it anywhere aftermarket for a direct application and I didnt want to go to the dealer and have to wait for it. So I went to Advance Auto Parts and matched one up myself. The hose I used you had to cut it down a little. The part number was: A71359 Dayco hose. Just thought this may help some of you in a bind!

Please don't hate me for reviving this thread guys, I just want to say I appreciate all the information on the forum. I just bought a 3.0 1991 4Runner, and I'm feeling pretty crappy about the condition right now. This is one of the problems, leaking weird little hose. I'll get around to this, after I install a new starter.
Looking forward to being a part of this community. |
Can anyone tell me if I am missing something here, why does it not show on the parts diagram? (the u-shaped hose in questions)

I replaced that hose a couple of years ago on my 95 4runner. The parts guy at toyota couldn't find it either. Just so happened a mechanic walked by and knew what I was talking about. It is listed in a different section. I can't remember which one.

If it crosses your mind, please let me know :)

I'll check and see if I still have my receipt with part number when I get home. I'm thinking it was on the screen with the intake manifold if I'm not mistaken.

Just to make sure. This is the part we are all talking about.... :)
(See attached) |
The coolant bypass hose (which started this thread) can be found:
http://www.toyotapartsoverstock.com/...rimLevel=18380 https://www.trdpartscenter.com/parts.../SR5/index.cfm Gevo's picture is a different hose; could it be part of the oil cooler? Hard to tell with all that dirt! http://www.toyotapartsoverstock.com/...rimLevel=18380 |
Yep. That's not the bypass hose I thought up were talking about. Sorry, can't help on that one.
|
Scope 103, I believe you may correct. If I remember correctly it was connected to that "Cooler Assy, Oil " gizmo. I will double check when I get home. It had a pin hole leak spraying coolant on to the exhaust pipe and steaming.
I'm generally pretty good with cars, but I don't have experience with oil coolers. The hose in question, although for the oil cooler, would still be carrying coolant and not oil, correct? |
That's not the bypass hose I thought you were talking about. Sorry cant help on that one.

The one in the pic is the oil cooler coolant hose, I think the one we are talking about is between the firewall and intake plenum, little upside down U going from coolant bypass to the little coolant manifold block back there.
Pain in the ass to get to, unless you move the plenum out of the way. |
OK, great, thanks for the confirmation. After seeing the oil coolant assembly I was pretty sure that's my hose.
Step 1, check. Step 2, find replacement :D |

Your time and gas are worth something. |

I gave you a link to one online source; $10.40 if I'm picking the correct hose.
Your time and gas are worth something. But, I think I will be able to make the 21 mile trip with the small pinhole leak anyway. So, I'll order online if I don't find it for comparable price tonight. I'm going to attempt to change the starter tonight.... :D |
So, I fixed it... For now. I had to get the 4Runner from my house to my parents, where I have a garage I can work in (all my tools and stuff too)
I barely made it to a nearby pepboys, had to stop a few times in 3 miles to add water since it was leaking very badly (so much for pinhole leak). Of course I knew pepboys didn't have this hose, I thought I'd for sure be able to mickey mouse something to last me a few more miles. Here it is after I removed the old hose. The little bushing fastened to the block needs to change too. https://lh6.googleusercontent.com/-r...918_115926.jpg This is my fix. Took me an hour to tighten the hose clamps! (this is before I tightened them) https://lh4.googleusercontent.com/--...918_121941.jpg https://lh5.googleusercontent.com/-c...918_121949.jpg At the end, the fix felt very good and the regular hose seems like it will hold with the metal guide keeping it in somewhat of a round-like shape. I may keep this for a while, mostly because I do not want to undue those hose clamps. lol. |

Oil cooler is in a separate parts section as are the heating hoses. And yes, that hose is a bitch. I was able to get the factory squeeze clamp on the upper, but for the lower I had to use a screwed on hose clamp. That upper post is removable and replaceable I think. For non oil cooled engines it's a plug I think... |
