I bought some radiator (leaky, cracked head gasket etc) sealer and poured it in the radiator according to directions. It seems to have done what it was supposed to do since I'm not losing antifreeze as fast now. However, it seems that the thermostat is now sticking. The temp needle on the dash goes almost to 200 F, check guages light comes on - I pull over - wait a bit - then start up again and the temp cuts back. Does this quik fix sealer stuff cause this problem? What should I do about it?

Under certain conditions radiator sealer will coat parts of the thermostat. It will also affect the bi-metallic coil that "reads" the temp of the radiator fluid, causing it to operate in an odd manner. Radiator sealer is one of those things that you use while you are waiting for your car loan to get approved, knowing that your current ride is going to the great highway in the sky in a short time.
On the other hand, 200 degrees F. is not very hot for a liquid cooled motor. Now when you hit 220+, that is when you start to worry. Since you gave no info on type of vehicle, engine size, age, etc., I can't be more specific.

Radiator sealer clogs passages that were already partially clogged. 200 isn't high for fuel injected. They normally have 195 thermostats and run at 210. Even a 180 thermostat will show 195 or so. If you have a cracked head gasket, that's your problem. It's doing a lot more than leaking a little coolant.

Remove the thermostat and drive without it. That will also lower your cooling system pressure. You might get a few miles more out of it. Once you have to use a sealer like that you need to start shopping for something else. That is just a band aid. You are going to have a major breakdown soon.

My experience has been that the quick sealer clogs the lower portion of the radiator. You should replace the thermostat and see.

in case you shop driving it with a blown head gasket or cracked head you will in all probability smash the engine besides so i might attempt the top gasket sealer if I relatively ought to no longer get the fix finished. Are you getting water interior the oil? Blowing steam out of the exhaust?

Yes it can cause your system to clog in several places,hopefully it's only the thermostat.You will need to flush the cooling system and repair the original leak.

No, it needs air to react and dry up. It could have sealed up some of your cooling fins however and got in he way of the cooling operation, which could have been on the edge before.
