Car running hot
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 1st tell me if since a supposed mechanic put 100% concentrate antifreeze in my car a while back(and I don't drive alot bc I work from home), an that cause this? In other words, what effects can that 100% have on the car and it's parts?
