if this is an s-10 blazer with the 4.3 liter vortec a very common coolant leak is failure of the intake gaskets leaking. When i was a machanic I've don't 2 to 3 of these a week on the blazer's. They finally redesined the gaskets, the old ones were rubber and plastic, the plastic would crack and leak,the new design is metal and rubber.Make sure when ordering them that you ask for the new design, alot of the parts stores still try to weed out the old style gaskets.
Hi Melissa, That is a very open question. Is the leak in the rad core, the side tanks, the hoses, the heater hoses, at connections, etc,
There is a temporary fix that i don't highly recommend but will work for small leaks. called rad stop leak you can get it at most auto stores. You are welcome to email me for further instructions once you pinpoint where the leak is. Marz
They also now make a bars stop leak that is made for head gaskets, head, intake manifold leaks that also seals smaller leaks, cost 29.99 at meijers works really good
