I have a 1996 dodge intrepid and when i start to drive for about 20mins, alot of smoke comes out of my muffler, especially when i hit the gas pedal at the stop lights. then it goes away...my temp. on the car is in the middle, so it;s doesn't look like it over heats or anything. Not sure what is wrong with? Could it be the coolant?...should i put 50/50 coolant?

Yes to the 50/50 coolant. What color is the coolant that comes out?

I ment to say what color is the smoke that is coming out, and are you adding coolant on a regular basis?

Thanks for the respond, yes the smoke is white and I don;t put coolant in it everyday. Should I put Prestone/Antifreeze and Coolant better than the 50/50 coolant? Or the Peak/Long Life Antifreeze and Coolant. How do I drain out all of the old 50/50 anti freeze? So I can place the new one?

Regardless of the brand of coolant, it needs to be mixed 50/50 with water. However, I have a concern. If you are getting white smoke from the exhaust, that means there is coolant getting into the combustion chamber and burning with the gas. It sounds like you have a bad head gasket.

What you need to do is check engine compression. Chances are you will find one of the cylenders has lower compression than the others. Here is a how to for checking compression:

Let me know what you find or if you have additional questions. Also, if you need the compression gauge, many parts stores will lend or rent them to you.
