i have an 03 mcs and today on my way to work i pulled onto a side road and ripped on it in first hit secdond still burning out and after i let off i noticed steam comming from under the hood. i pulled over and opened the hood and noticed coolant had overflowed from the reservoir onto the manifold. temp gauge was normal and was fine for the rest of my ride(went easy on it). has anyone had this happen before? guys at the shop i work at were thinking possible head lifting off the block from boosting this is the first its happened
