The location will more than likely depend on the model of Saturn
On the 4 cylinder Saturn, follow the top radiator hose back to the engine. Note that there is a housing that is bolted to the engine to which the radiator hose is connected. Remove the radiator hose first, then remove the housing. On the 4 cylinder Saturn's, the thermostat is a part of that housing.
Probably on the engine end of the upper radiator hose Probably on the engine end of the upper radiator hose
How do I remove the screw/bolt holding the AC unit lines to the radiator on the driver side.
Thermostat location — 1997 Saturn SC1 4 On your 1997 Saturn SC1, the thermostat is not on the top of the engine like many cars — it’s located: 👉 At the engine block where the LOWER radiator hose connects 📍 Exact spot Follow the lower radiator hose from the radiator It leads to a metal housing (thermostat housing) bolted to the engine The thermostat sits inside that housing 🛠️ What you’ll see 2 bolts holding the housing Coolant inside (so expect spillage when opening) Positioned low on the passenger side of the engine ⚠️ Quick tips before touching it Let engine cool completely ❄️ Drain some coolant first Replace gasket/O-ring when installing new thermostat 💡 Common mistake Many people look near the upper hose or near the head — ❌ That’s wrong for this car ✅ Always check the lower hose connection
The thermostat is usually located on the lower hose, where it attaches to the radiator
A 1994 Saturn SC may not even have a radiator drainplug. In order to find out if the 94 Saturn does have a radiator drainplug, a person can take off the lower hose to see, or look in the car's manuel.
Look for a removable housing at the engine end of the upper radiator hose you will have to drain the radiator fluid first because the thermostat is fairly low Follow the lower radiator hose on the passenger side to the engine its in a housing so you have to remove the radiator hose then the thermostat cover with the 2 bolts
Should be in a removable housing at the engine end of the upper radiator hose
The plastic tank on the side of the radiator can be replaced but it would be quicker and cheaper to just install a new radiator.
To remove the radiator from a 2007 Saturn Ion, first ensure the engine is cool and disconnect the negative battery cable. Drain the coolant by opening the radiator drain valve and removing the lower radiator hose. Next, disconnect the upper radiator hose, any electrical connectors, and the mounting bolts securing the radiator to the support. Finally, carefully lift the radiator out of the engine bay, being mindful of any remaining coolant.
Follow the top radiator hose to the engine, what that mounts to is the thermostat housing, remove this and there is your thermostat. * ** *** **** ***** Actually, on my 1997 SL2, the thermostat is on the bottom radiator hose. I would check the "Saturn Thermostat Pictures" link below, which also has installation and removal instructions.
You have the hose from the engine (bottom) that goes into your radiator, and one from the radiator to the motor. The sensor is where the second hose plugs into the motor. Be careful when you loosen and torque the bolts, they're fragile.
