I had a cracked radiator with low antifreeze when my mechanic looked at it. Put a new one and it feels much better. This is a noob question but, does the radiator/antifreeze have anything to do with the way the car rides? I thought before I brought it to the shop it was going to need new suspension/shocks/struts or whatever but he said they were fine. After i got the car back it feels like it rides a little better/smoother?????
