Thanks again Lusko. I was thinking cylinders, but wanted to check and make sure. I really do appreciate the information.

Hey powers1 - Just thought I would ask about the water temp sensor. Thanks for your help as well. I need to research that problem a little bit more. I have a 2004 Mercedes C240 that can run for 5 minutes and will melt plastic in the frozen tundra when the heater is on high and it takes at least 20 min for the X5 to blow warm air. Oh well spring is near and the cam sensor needs my attention at the moment.

Thanks again,
