Radiator is leaking on my 3k ..wondering if i can pour in some stop leak or if I'm better off paying mad$$$ to replace it? The coolant leaks gradually, causing my car to start overheating

girlll u found it :) got no new advice 4 u tho sawyyy

you can but theres a good chance youll clog the radiator and make car overheat.

My suggestion to you is get it fixed, if you do put some kind of leak stop it may have an effect on another part of ur cooling system for example your thermostat (a valve that opens when a certain temp. is reached to allow complete circulation of the cooling system) if that some how gets clogged with that stop leak you may overheat your engine.

a radiator is not expensive and an easy replacement. if its a tt its a definate no but a base is alot cheaper to fix. liquid glass is for beaters, not a car you love. that said liquid glass has saved people alot of money and some people swear by it. if you can see the crack jb weld can be a permanent temporary fix with no risk of gummin up your internals
