dear. my blazer 4.3 vortec has fan wrong, and I drive for 7 minutes at 120-130 ºc (240ºF). was it dangerous?

240 is much too hot..

where are you from?...and welcome!

I'm in Chile, and I received new fan, the blazer doesn't have any problem. but I have the doubt

240 is hot..but it usually takes 260 to cook one

How do I change the spark plugnumber 2(drive side)in my blazer s-10 1995 4.3
Definitively there is no place
