I'd recommend a factory thermostat. That way you know you're getting the right thing. <img src="/forums/images/graemlins/kewl.gif" alt="" /> I know that on my Toyota's, the aftermarket thermostats have this cheap lightweight spring on them but the factory thermostats have this heavy duty spring on them.

On that thermostat, it'll probably only go on one way. Typically, the spring will be on the backside where the other side is the outlet (flow wise).
