OK i have a leaking radiator and i bought stop leak. Only thing is that I have never used this before. Please help

return it to auto store and use the money to help buy a new rad...you dont have to go aluminum or dual pass or anything but just get a new one..there not expensive and vital part to keeping your little rotory enfurno cool

 

ok ty

 

Stop leak and other fixes hurt other parts of the cooling system.

My rad leaked, I took it to a local rad shop and asked if he could check it over and or fix it.
He put new "O" rings in the top and bottom, fixed the leak, cleaned it inside and out for around $60.
Working great.

 

I'd just replace it with a new one or one from a junkyard. If you get it from the junkyard make sure you can take it back if it fails within 30 days and pull another one just in case it leaks too.
