Default Coolant line broke off

Hi everyone!

Have an issue. The coolant line to the reservoir popped off when I cleaned the engine. What is the best way to fix this so I can drive the car on Monday?

Is there an easy fix/temporary fix and what part do I need?

Thanks so much for your help!

your best chance is to replace the tank , that nipple is part of the top and are know to break. Needswings has the tanks and can ship to you .

as a quick fix you can try a piece of 1/4 copper tube about 2 inches long ... take the broken part out of the hose and you may need to enlarge the hole in the tank slightly . the copper should be snug and try silicone to seal the copper to the plastic ... it should hold till you get a new tank but most likely you will have a small leak until the tank is replaced ... threading a nipple into the tank might also work

Although I have seen people drill out the nipple on the tank and thread brass connectors into the plastic..........
I still feel the most secure way to fix it is to simply replace the tank

Rob @NeedsWings has them here in the link below

If this is for a SRT6, the expansion tanks are discontinued. If it is for a NA, they are still available and used ones are available.

Thank you for all the helpful replies. Since I have to use the car for a work trip on Monday I would love to be able to fix it.Easiest method to make this work is much appreciated.

However, this is a SRT-6 and so I need to purchase.a SRT reservoir wether new or used I guess as long as the nipple has not disintegrate. Hope to find one but in the meantime I need to fix it somehow so tha the car is usable and reliant till I return next Friday.

If you use the brass barbed connector, it will be the last time you need to mess with it; IMO.

yes the srt6/slk32 tanks are discontinued. if you want to drive on monday, go pick up a brass 1/8npt to 1/4" hose barb (guessing on this size, measure to confirm) fitting,

https://www.acehardware.com/departme...BoC5e0QAvD_BwE

then drill and tap the broken hole to accept the brass fitting with teflon tape/sealant and hope for the best.

i may have a spare tank in my parts pile but it would not be to you in time for a monday trip.

No matter which method or hardware you use for a temporary fix, JB Weld is some good insurance against leakage and another break at the repair site. It comes in types for water, plastic, and steel (metal) applications and when applied properly and given a little time to cure it will form a seal. I would use the water version, but any of the 3 will do just fine. Make a small "worm" with the material after mixing it with the activator by rolling it between the palms of your hands (wear gloves). Then encircle the new nipple/connection with the "worm" and press it in tightly around the fitting. It hardens quickly, but I would wait a couple of hours at least before connecting the hose and filling the tank.

Thank you for all the suggestions. @NeedsWings do me a favor and check the attic, basement and anywhere else you might still have one I will most likely take it anyways but I am going to try and fix this for Monday.
I appreciate all of you!!

I meant to quote the fix post as below, but it did not show-up, so I have edited this to reflect that since I cannot figure out how to delete it and it is confusingly redundant. Sorry. I am better with carbon paper and a mimeograph machine!

Awesome fix! I love it when the "fix" is superior to the OEM parts that broke. I am seriously considering doing this before the nipple breaks since it appears to be a matter of when and not if. We have some incredibly talented folks on this forum. I learn something every time I check-in.

this is not a superior fix, this will eventually fail at an inopportune time. while some are still holding, most eventually leak/blow out past the brass threads in plastic. sure gooping some jb weld around it may help. i think i will eventually make up an aluminum reservoir

Correct me if I am wrong - but don't the OEM tanks ALL FAIL "eventually"? I can't imagine that there is an opportune time for either the OEM or the fix to fail. The fix is certainly less expensive than paying whatever the going rate is. And ask the SRT owners how superior an OEM tank is that is no longer available? Give me threaded brass and epoxy over a cheap plastic nipple any day.

The problem is going to be the next time you have to p-ull that hose off of the brass nipple. Be sure you hold the nipple with vise grips or ???

Why would you pull it off unless you were replacing it? In which case - cut that bad boy! If you have worked your way through the OEM tank/nipple, and a fix, it's probably time to replace the hose anyway. But I get your point... and it's probably no picnic getting the hose ON there to begin with!

That would be a great item to add to your already extensive line of replacement parts for out Crossfires
