I've been having issues with a dodge intrepid i recently bought. It has the 3.5L engine in it but i can't figure out what the issue is. It overheated and died on the side of the road. I've been reading a few articles that suggest it could be the intake manifold gasket. I've also heard the thermostat and water pump could be an issue. I've noticed it is leaking oil and may be leaking coolant as well. Suggestions? I don't have much money to send it to a shop, seeing is that i just bought it.
