radiator replacement

I replaced my radiator in my SC400 with 120,000 miles two months ago. New radiator and install 250.00 dollars. Ed G

I HAVE TALKED TO ANOTHER OWNER OF A 1992 SC400 THAT HAS GONE THROUGH 3 RADIATORS. I HAVE A RADIATOR WARNING LIGHT THAT COMES ON WHEN I FIRST START MY CAR AND GOES OUT IN 1 MINUTE.. I THINK IT MIGHT BE A SENSOR? BUT AT 157K WHY NOT DO IT TO BE SAFE... DON'T WANT TO DAMAGE OTHER PARTS OF YOUR ENGINE.
