this is probably a stupid ? but i bought a new ranger. well new to me its a 2000 3.0 2wd i know the thermostat needs replacing on it. my question is i lost my haynes book, and i dont remember which way the thermostat sits in the truck. cause when i opened up the housing, it didnt have one.the owner before must have took it out for some reason. so i just need to know which way it sits spring side inside the thermostat housing or inside manifold. thanks alot!
