My 1988 Chevy Blazer has developed a gas smell the past couple of months. I have a leak in the radiator and have to top it off with 50/50 antifreeze. Could this cause the smell of gas?

Gas smells totally different than antifreeze, and it would not cause the smell of gas. If you are smelling gas there must be a leak somewhere. Look for wet spots from the throttle body back to the gas tank.

The reason I mentioned the antifreeze was someone told me it could get in the gas causing a smell of gas and white smoke from the tail pipe. Thank you, I will look for wet spots

What they were talking about is if you had a blown head gasket, antifreeze can get into the cylinder and burn out the exhaust thus causing the white smoke. That is the only way antifreeze could mix with gas.
