I know I have seen some post on here about changing the thermostat but I have a few more questions. On the 2.3, can I just buy a new thermostat or do I have to buy the whole thermostat assembly? Secondly, the thermostat is located by following the the lower radiator hose? And lastly, I am glad I wasted my money on one of those Haynes manuels. Also, I hope the thermostat is my problem. I am sure it is, as the temp. needle never gets over the cold line and the heater only gets hot after about a twenty minute drive. I am open to all suggestions. Thanks.
