i have a 2000 chrysler lhs it was at a shop had radiator and thermostat replaced after driving it and good 4+ miles it over heats starts steaming out the coolant tank fans turn someone help me

yes the cap is located on the overflow tank its a what they call a sealed system

i own one as well and i haven't had any problems except for putting a lot of money into it to get it back the way it is supposed to be after buying it off a guy from craigslist but i work on it myself and i love it. if you have any questions about anything about it e-mail me at hobbozombie@hotmail.com

Sorry to hear about your car problems, I am having the same issues. I have replaced the water pump, timing assembly, belt, and hydrolic tensioner, the ac belt, serpentine belt, thermostat, radiator, overflow tank and cap, upper radiator hose, two diagnostic checks done by two different companies.A local well known and dependable company did the first diagnostic check, and Firestone did the second. Lastly I had a pressure test done that held for over two hours without leaking. Because the pressure test held and there is no water in my oil or oil in my water and it is not smoking I don't believe that I have a blown head gasket. Firestone seems to be stumped as well and say that they think it may be a blown gasket, but I have gotten other opinions and they believe as I do that its not a head problem.The other suggestions I have gotten are air in the system or a bad thermostat. Please if you have any other info about yours can you share it with me. I suggest you don't spend a bunch of money as I have until you are sure what the problem is.

The way you describe driving 4+ miles before overheating is exactly the way my 2000 lhs does, so I believe if one of us figures out the problem it will solve it for both of us.

You gotta bleed the coolant in theses cars its at the top front of the engine a small brass fitting just back it off a bit till you see fluid running out of it then tighten back down
