Question about 1998 Buick LeSabre
I have never had a radiator leak cause white smoke. if youre leak is coming off youre radiator then needs to be fixed by a shop or a do it youre self job. the white smoke on the other hand can be cuased by three mian things! one, you have head gasket that is leaking internaly, check by pulling youre spark plugs one at a time to find a clean on, if you find one youre head gasket is allowing coolent into the cylender which means you need new head gaskets and have youre heads inspected to make sure there not worped #two, youre valve guide seals are wore out and they are allowing oil to seap into the cylinder thus you are burning oil and the third cuase for white smoke could be that youre engine is running rich by the fuel mixture being off. but with the car you have i would check yhr first two! i hope this helps.
