YES - BY back flushing the heater core-same as back flushing the engine block-just use a garden hose.
Usually 'Stop Leak' will not clog the core. Try flushing the cooling system out first.
Note: The hot water goes in and the cooler water comes out. Flush the core going the other way so to clear any obstructions. If there is a clog, it might be something larger like bits of hose or corrosion. If the core is totally clogged, take it out and replace it with a new one. The amount of time you will spend doing this does not warrant using an old or used core.
I have used radiator stop leak before in my 1996 Olds Achieva SC with the V6. I put it directly into the coolant resovor. It went in fine for me. This did not give me much help though. I would not recommend using stop leak. It will clog your heater core and then you will have more than the radiator as your problem. Fine a new radiator and replace it that is the best advidce i can give you.
There are lots of places that can leak freon and some can be sealed with stop leak. The only way is to try it.
I wouldn't recommend it. Replace the gasket.
Make sure coolant level is correct It could be a clogged heater core,maybe it is a birds nest or a rats nest if the car was stored.Usually replace the heater core and it will solve it or maybe it is the radiator itself needing flushed.also it could be the switch is not throwing to the position it should be.If the car was in cold climate before maybe it froze over and then was dooshed with heater core repair stop leak.Thats the best I can guess...
The transmission will not work without fluid.
If it is water you have a plugged condensation drain line that needs to be cleaned out. If it is engine coolant you have a leaky heater core that needs to be replaced.
It can.
the heater core could be clogged with rust or stop leak . or u don't have enough hot water flow through the heater core . under the hood on most cars on the heater hose is a off/ on valve to control the flow of hot water...anti-freeze...to the heater core.....R
caused by leaking heater core not radiator heater it is under the dash hard ot get to if the leak is not to big use radiator stop leak otherwise fix is going to be big bucks
Be careful - some of these products can plug the heater core
Stop leak will generally plug up holes u want plugged, but they will also plug up holes u don't want plugged. Better to fix the heater core.
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.
if it is leaking from the radiator you can crack an egg and put it in the radiator and it will solve your problem
It is inside the heating A/C housing. The dash has to come out to get to it. A very involved repair. Even the most experienced master mechanics cringe at having to do a heater core repair. I would suggest putting some aluminum stop leak in the radiator. It will stop the leak in the heater core and will save you the grief of pulling the dash out.
It should work assuming the leak isn't too big. Try it you have nothing to loose.
Repairing the leak depends on where it is. A stop leak additive may help for a while, but use care as some additives can cause the heater core to clog up.
You would pour it in the radiator. Caution, stop leaks usually clogs heater cores.
