i have the honda coolant and want to change it in our 2001 civic..... i have never messed with a 4 cyl. engine before and was always told that there is a air bleed bolt that you have to remove to bleed the air out of the coolant system in a 4 cyl. engine when you put the coolant back in so you dont have any air pockets.. i dont have any manuals for this car yet, seems haynes did not print up any 2001 civic books yet or i just cant find them.. any help locating a bleed bolt on this car???? thanks in advance....
