Some of our cars seem to lose coolant quicker than others in hot weather because of evaporation and such, several forum posts talk about this.  This comes in handy at the end of the summer to top off half with the radiator and the rest into the overflow tank. Make sure your doing this with the engine warmed up and the radiator and overflow cap off from the start, and make sure you follow normal procedures to bleed the system if your starting out fresh.

This is something good to have around since our cars have been known to lose coolant overtime. No need to mix, just ready to use.

I really needed coolant for my 86 , I had called multiple dealers just to tell me that they didn’t have anything is stock (due to not a high item to restock) so I turned to 86speed.com and it was here in 1 day! Thank you for your time and service! Very happy customer and will buy more!

Just used this to do my coolant flush and couldn’t have been happier . OEM is always the way to go for maintenance
