I have had the  misfortune of having someone drive my Carat without my
permission during my stay in a rehab hospital and subsequent recovery
period. The water pump belt failed and they kept on driving,  trying to get
to destination and avoid the inconvience of a stop on the highway. I am
afraid they may have destroyed the engine in their ignorance  of the engine
in this van.

New belts have been  put on, and antifreeze replaced but the mechanic says
the engine runs  rough às a cobb.

What should I test on this this engine to check it out?

If a rebuild is required, I have a local rebuilder who is very, very good
but I need to know of anything I need to bring to his attention. Also might
be  done to make for a better rebuild.

Thanks,

John
