No, but children's modeling clay can. I used it once to fix a seam in a radiator that I had in an old car. I put the clay on the seam and covered it with foil. When my dad got around to fixing it he had problems getting my patch job off.
If your 1998 Jeep Cherokee is leaking coolant, it might be a seal but it is more likely that it is a hose. This might also be a radiator leak, a loose hose clamp, or the freeze plugs in the radiator.
Several possibilities: 1. Radiator is leaking. 2. Coolant hose is leaking. 3. Hose clamp is loose. 3. Seal on water pump is leaking. 4. Overflow container is leaking. 5. Radiator clamp is loose or bad. Two highest possibilities: Radiator or hose is leaking.
You likely need to replace your radiator cap - the rubber seal in the cap is worn.
your main oil seal on the rear of engine is leaking or the timing cover seal is leaking,
NO... They are 2 different seals. If the transmission seal is leaking then the fluid color will be RED that's leaking. If the rear main seal is leaking then it will be oil leaking from the engine and it won't be red.
The question is referring to pour in type cooling system sealers such as Stop-Leak. If the radiator itself is leaking Stop-Leak will likely come right out as it is designed for small seal and gasket sealing.
If it's leaking at the radiator, make sure you haven't accidentally bent the fitting. Sometimes a brass fitting can be accidentally bent and you'll never get it to seal until it's round and cleaned up. If it's leaking at the block or water pump, make sure it's clean and there are no large corrosion pits. If everything looks good at those locations, check for leaks elsewhere. The radiator could be leaking where the hose connects. The water pump could be leaking and it only LOOKS like it's leaking at the hose.
If the torque converter seal has failed you will need to pull either the transmission or the engine. If it's a half-shaft seal you won't need to pull the engine, just the axle shaft. I am the original poster, it is now leaking tranmission fluid & antifreeze at the same time. If it is leaking at the transmission cooling line in the radiator do I need a new radiator or can hoses be replaced or nuts tightened?
Heater core leaking? Windshield seal leaking? Door seal leaking? Evaporator drain plugged?

That's an easy question. You replace it when it's leaking all over the inside of you truck and radiator "leak stop" wont seal the leak. As long as it's not leaking you don't need a new one.
Because your transmission has a seal that is leaking.
