My car ran hot only while the A/C was on one day recently. I looked up some things. Think I know what it is. But, can you first tell me if since a supposed mechanic put 100% concentrate antifreeze in my car a while back(and I do not drive a lot because I work from home). Can that cause this? What effects can that 100% have on the car and its parts? What effects can that 100% have on the car and its parts?" And can it eventually cause the fans to stop turning?

Hello again.

Having a 100% concentrate of antifreeze will not harm an engine or the engine components nor make the fans not work. The optimum ratio for antifreeze is mixed 50-50 with water. There is only a slight chance of running hot because of the mixture. If the level is low just dilute by adding water. Hope this helps and thanks for using 2CarPros.
