Hey all. I'm fairly new to working on vehicles and recently finished up a replacement on my cooling system. Replaced the radiator, hoses, water pump, thermostat and housing. Now my temp gage will go up about 1/4 of the way then drop back down so I know that the thermostat is opening and closing. And my mpg' s went from 15-16 down to 13 on my last fill up. So I don't think it's simply a sensor reading the temp wrong. I'm lost on what to do next except for taki ng off the thermostat housing and making sure the thermostat isn't in backwards. If anyone has an idea on what I should do your input would be greatly appreciated. Truck is a 91 4.0l v6 if it makes any difference.
