If you can afford to fix it right that is a better option. Otherwise it depends where the leak is. Bars Leaks 2 Part Engine Fix works great and even will restore engine performance.
Stop leak products can temporarily seal small leaks in a water pump, but they are not a permanent solution. These additives work by forming a seal within the leak, but they may not address underlying issues or larger leaks effectively. It's best to use stop leak as a short-term fix and consider replacing or repairing the water pump for a long-term solution. Always consult a professional for the best course of action.
If additives are so great why doesn't the vehicle's manufacturer add them from the start?
almost never
try using power sterring stop leak, if they doesnt work, find out what is leaking, and replace the worn hose or broken seal
It should work assuming the leak isn't too big. Try it you have nothing to loose.
Are you sure it is a antifreeze leak? If so ,stop leak will not help heater core leaks.But make sure that is the problem.
NO! its like looking for a magic pill to make you younger or live longer. Do not use it you will clog up the entire system and wind up replacing it. Find the leak and properly repair it. YES IT WILL STOP THE LEAK BUT NEEDS TO BE REPAIRED ASAP IT IS NOT WISE TO US IT BUT IT WIL STOP A SMALL LEAK.
by replacing the bad gasket / seal
It will "work" but is never a good idea. Stop leak not only stops external leaks, but also plugs small internal passages in engines and radiators, which can lead to overheating.
The transmission will not work without fluid.
IF THE LEAK IS FROM THE RADIATOR, THERE IS NO FIX EXCEPT TRY THE RADIATOR STOP LEAK CANS OF FIX....IF THAT DON'T WORK, GET A NEW RADIATOR. THAT'S ALL YOU CAN DO!!!!!!!!!!!
YOUR WASTING PEPPER. It won't work. Replace the radiator.
