I have a 2000 Dodge Dakota with 200,000 miles and noticed it was leaking coolant around the timing chain cover. I did a little research and fixed it myself. Since I had the timing chain cover off to replace the gasket, I went ahead and replaced the timing chain, water pump, and thermostat since they have never been replaced before. I probably saved $800-$1000 in labor, and it wasn't that difficult. No more leak and runs like a champ!
