Can Radiator Leak cause "Check Engine Soon" to Come On ?

Question: I know there are a lot of reasons the computer can throw a CEL, but could a small leak in a Radiator cause this ? Thanks in advance.

In the radiator? No. But as stated below...Low coolant probably would though. lol

umm...yes it can...too low of fluid=no good for temp of sensors=cel...but that all depends on how low it gets. but if you want to know what the code you have is...go to autozone and give them your license and go pull the code off of it with the reader they'll loan you.

soes Auro Zone still do free diagnostics or lend you the tool ? It seems everytime I go to one where I live, they say they don't do that anymore.
