If something is wrong with the radiator, would my check engine light go on?

 

The experience's I've had with check engine lights are that they usually have to do with the O2 sensor. But this was in my 1996 Toyota 4Runner. Haven't has the luck of the check engine light coming on in my gsr.

 

me too. every check engine light ive ever seen come on was for the O2, on my teg and on my dads steeda mustang. the one exception is right now because i burnt a valve. come to think of it my radiator is leaking also.....hmmmmmm. well im sure that was of absolutely no help....sorry.
