Thanks dcotter0579,

Any specific brand of coolant I should be getting? I get that I need the 100k variety but what product?

 

There are numerous brands. Probably several of the brands are made by a few manufacturers. Read the label to be sure you are getting the right stuff and shop for a good price. I got my last antifreeze at the Valvoline oil change store. They make Zerex now, I think, which used to be made by Dupont.

 

I called Goodyear and told them my heater was not getting good heat all the time and they told me to make sure mt antifreeze was not weak. Does this sound right? Some days it works great and others it blows cool air. Any advice?

 

nope nothing to do with that U can run straight ware in an engine and still have heat come from the heater core. Low coolant would be my first guess
