Changing a thermostat on a 99 Plymouth Neon?
its pretty easy find the radiator the big silver thing in the frontthen find the upper hose and find where it meets the engine there there will be a couple of studs take those out lift it off and pull out the thermostat out of the hose and then put in the new one THE RIGHT WAY and put the hose back on and make sure the temp of the new thermostat is the same
