Can the radiator be repaired with some type of radiator stop leak.

Epoxy or other types of "quick fixes" will not work, or if they do won't fix the problem correctly. Even stop leak just plugs the hole from the inside, and plugs up the system. Best bet is to try and find the problem, which is usually a leaking hose, water pump, or radiator.
Once you find where the leak is coming from I can advise better on the best solution.

Most auto parts have stop leak for radiators, the recommendation is that you empty the radiator of coolant, pour the stop leak in the radiator and then fill with water. then run engine until it gets hot, there is a catalyst like liquid glass in the stop leak that expands with heat,but as it flows out any hole will turn soild, and stop the leak.once the leak is stopped and the car cools down, drain the water and fill with the proper level of coolant. but if the hole is to big may require some repair from a radiator shop. good luck!

Radiator leaking...nothing to do here but replace it. The "new" aluminum and plastic radiators cannot be repaired. Kinda sad considering how new this car is. If you need a temporary fix and it's a fairly small leak there a lot of stop leak products on the market. Check your local parts house not the dealer they will rip you off big time for a new radiator and tell you can't use stop leak but it really does work pretty well, but you will need a new radiator, no way around it.

first off i dont advise using this type product, but i know it isnt always convenient to buy a 2 r 3 hundred dollar radiator, but anyway, with the car cool remove the radiator cap and let the car run about 4 or 5 minutes and pour it directly in the radiator and replace the cap, you will then need to drive the car an additional 15 or 20 minutes for it to take effect, i would replace the radiator asap, asit could cause it to overheat and cost tons of time and money,GOOD LUCK!

I never recommend anyone pour any stop leak in the radiator of any car. But saying that if you are going to replace the radiator and do not have the money to do so now, then go ahead and use Bar's Stop Leak as an emergency repair. Just make sure to flush the system fully, and replace the thermostat when you do replace the radiator.

There are products out there like stop leak that MIGHT stop the radiator leak. However... the only real repair is either to have it soldered (if the end caps are not plastic) or replace the radiator all together.

Adding a product like "Stop Leak" most often starts to introduce other problems to your vehicle like a future water pump seal failure or clogs in the smaller water passages in the engine block, heads and manifolds and the thermostat heater bypass hole. Anyone that has ever done any major engine repairs will know immediately if stop leak was used in a cooling system.

The best fix is to replace the radiator.

Many radiators today can not be repaired

Stop leak is in most any auto parts store. Just be advised of what you can expect down the road.

specifically

1. warmer than usual engine operating temps
2. water pump seal failure
3. heatrer core clog (no heat)
4. passenger heat control temp valve clog (no heat)
The choice is yours. Personally I would not do the "Stop Leak" treatment attempt. Sometimes it works other times it does not.

The stop leak have restricted the coolant flow to your heater core. You can try flushing out the Stop leak with Preston Radiator flush or replace the heater core. Once Cooling system flushed out, replace thermostat, radiator cap and repair coolant leak. Good luck and hope this helps, and Note: Common Black kitchen Pepper does great as a radiator stop leak without leaving any residue and can be cleaned out of the system with water and not coolant flush. Two table spoon is more then enough to stop a small leak. Good luck and keep me posted friend.

NO-NO-NO-NO NO

If you have to use stop leak drain out some coolant and remove the upper rad hose and poor it down there. IF you put it in the reservoir it will sit there and stop the return. You will think it is full and your system will be empty.

If you have 4.0 you may have a head gasket leaking. If it is running ok and you are loosing coolant contact me back and I will tell you a good fix that works

It’s plastic and aluminum try using bars radiator leak but if it's bad it's plastic and aluminum and hard to repair. They are throw away’s

Hi, you 1st have to determine the exact location of the leak, which may involve removal of the radiator to repair anyway. How bad is the leak? How often do u have to add coolant, and how much? If it's a minor leak, you can purchase 'radiator stop leak' from a parts store, that will seal it.
so, try the stop leak if it's a minor leak, you can have it removed and repaired, or purchase a new one. Having said all that, the leak could be a hose leaking, but running down and dripping off the radiator making it look like a radiator leak. With engine warm but not running, use a small mirror to hunt around to see if u can find the source of the leak. Look closely under the radiator hoses, as that could be where the leak is. It would be from the radiator bottom and up, any further back and it wouldn't show up at the bottom of the radiator, so no need to check back any further. Let me know what u find,good luck countrycurt0
