Hello. My name is Tom Burns snuff certified mass mechanic from Redding, Pennsylvania. Today we’re going to talk about how to know when to replace a fan thermostat. I’m just for clarity. There is no fan thermostat. Um, there’s either a thermostat that controls the flow of corn through the engine or those the thermostat that will, I mean a coolant sensor that will turn on an electric fan. Um, but no fan thermostat if you need to replace your thermostats, usually in the third step by behind the thermostat housing. Couple bolts, two-three hoses. Not Real hard to change as you see if you have an electric fan. Um, is computer controlled, it works off of a sensor, usually close to the thermostat housing or it’s usually on the side of the radiator. You’ll have to check a repair manual seat where the location is a, uh, a competent part store locally.
Be able to tell you what it looks like, show it to you. They might even tell you where it is. Um, this particular vehicle, the Fan Thermostat, the panthers, the fan sensor, the temperature sensors right here in the thermostat housing. Um, we’ll get a shot at here in a second. We will easily change. You needed a three-quarter socket and a ratchet extension. Disconnect your, your connector on it. Pull it right out. You might want to relieve the pressure in your radiator cap right here first. Make sure the engine is not hot before you start this process. Fill it out that you knew one screw right back in. Push connected back on. Fill it back up a corner, him to about 195 degrees, about 210 degrees. If it’s an electric fan, it will turn on under that. Um, it will turn on to that point. But just make sure you keep your hands away from the fan.
You don’t want to sit in there and trying to turn it thinking it doesn’t work. As it turns out on the town and I caught a bad day. Um, other fans you have, you have a clutch fan that’s this also a spring. When it heats up, it expands, locks that fan and starts turning it. So again, don’t put your, if you have a clutch fan, don’t put your hands in there cause you don’t know when it’s going to start turning. Um, it will free spin for a, until it gets up to temperature and it locks and then then I’ll start working. But other than that, it’s, it’s really simple. You have either or, you have a manual fan or electric fan, electric fan. It has a temperature sensor, works electronically through the computer. The thermostat is in this housing will simply change.
