My left side radiator vent hose keeps popping off. (Done it twice, expensive and time consuming!!!) It seems the aluminum hose end is NOT fitting tightly into the plastic (yes plastic!) radiator end and the clip is NOT holding it in either. My Indy told me that this is sort of common on higher mileage cars and there is an updated or superceded radiator and vent hose now. The vent hose is the 5/8 to 3/4in rubber hose the goes from the radiator to the aluminum line in the wheel well. The clip goes over the plastic female end on the radiator and the hose has an aluminum end with an O ring and 2 "ears" that the clip grabs when it is inserted. Does anyone know the part number for this superceded radiator? (Sorry about the crappy cell phone pic).

 

I do not know the Part number you are speaking of. I would suggest using some safety wire instead of the clip to hold it until the final fix is taken care of. You can twist the end tight so it doesn't just popoff. Good luck.

 

Thanks, but I thought of that, and being that this is the second time this has had to come apart and I've spilled $150 worth of coolant al over the road, I'm looking to fix it permanently. I guess I'll wait until my Indy gets back from vacation. I'll post the superceded part number if there is one.

 

When I was replacing my center radiator after striking a groundhog on track at well over 135mhp, I found the hose to radiator connect has to be perfect or it will not allow proper connection. Also, the aluminum ends wear as that aluminum is very soft, and the plastic of the radiator end may also now be out of spec for the hose to fit properly. You'll probably have to replace the hose and the radiator both to have 100% confidence it's "fixed".

Exactly Mike, The aluminum end isn't fitting very good now and the plastic on the radiator isn't looking all that great either. I can feel the O'ring seat but the fitting still moves around and the clip BARELY grabs the ears on the alimunim end, which ultimately IS the problem. If that clip moves AT ALL, it will not grab the "ears". I was told the "updated" or "superceded" version has a plastic hose end that goes into the plastic radiator housing now and it doesn't wear as fast? It's $450 for the radiator and $25 for the new hose. I'm tempted to do both sides as it seems inevitable, but I need tires now too, so maybe I'll just do the bad side for now.

 

Ok, this is what I've learned today. The HOSE has been superceded, NOT the radiator. I just ordered it and should have it Monday. If it fixes it, I will post part numbers and results and maybe pics.

 

Good to Know. I had a smiliar problem with my factory boost hoses a while back and was told to bend up the ear on the hose part with a small flathead so the clip will grab it more. Worked very well. Maybe you can try it on your rad hose, they look like a similar design?

 

The ears are CAST into the fitting, they are not metal straps, nothing to bend. I will take better pics when I get the hose and finish it.

 

Hopefully it works for you...

I don't know if this applies to your case, but back when I had a Supra TT, the IC hose would pop off at times. T-bolt clamp did the trick...

 

Wow, that is one crappy cell phone pic!

 

Does not apply to my case. I do however agree with the T-bolt clamps...unbeatable. Hose clamps are for house plumbing!!! The Germans saw fit to connect all their hoses with metal ends that are held in by clips...

 

Don't you have some work to do???

 

I wish!!!!!!!!

 

OK. Hose came today. Car is back together. Still need to find some coolant and begin the arduous tack of bleeding. (Made a slight modification, for insurance purposes). The aluminum ended hose is original, the hose with the plastic end is the superceded hose, part number exposed.

 

Looks like this hose (and my little "insurance wire") did the trick. 2 good rides a no leaky...in case someone has this issue the part number for the "superceded" hose is: 996-106-137-77. I think you can see it in the picture, I just put it here in text so a search could find it
Thanks for listening!!! Now back to our regularly scheduled posting...
