my radiator is leaking a tiny bit in the center. i am pretty sure stopleak or whatever those pellets are called will work as i have used them before.
but.. i have heard they can be bad because they can also sieze the water pump.. but then apparently if you flush the system after you use it that reduces the possibility of that happening
so while my best option is to replace the rad, is stopleak ok to use? can someone set the record straight plz
