small coolant leak on drivers side when care sits over night. Car has 3.5L engine with 118000 miles. Purchased used a few months ago. Just started leaking a week or so ago. Dash came on with low coolant level. Added a small amount of coolant ( at the add coolant level line) and then started noticing small amounts of coolant under car in the mornings. Any suggestions or ideas?

On that side it may be a hose, but it's probably crossover gaskets. They're kind if hard to see, an inspection mirror will help. Fairly common on this eng.

are these gaskets hard to replace? Are they any instructions pictures anywhere to help me get started on this project.

It's a fairly in depth proceedure, I would look for a manual for some guidance. But first you should find out FOR SURE what is leaking.
