Check the following.............................
1. Cooling fan operation.
2. Radiator cap.
3. Thermostat.
It's only radiator cap is on the coolant reservoir.
he radiator
The radiator on a 1995 Saturn is flushed by draining the coolant, refilling the engine with water, and adding a flush. It is allowed to circulate and drain before refilling with coolant.
R134a
at the bottom of the coolant reservoir tank.
Low coolant? Cooling fan not working? Thermostat not opening? Cooling system air bound? Water pump not circulating coolant? Plugged or restricted radiator? Defective radiator cap?
If Im not mistaken, the Pressure cap for a Saturn is the twist on cap on top of the coolant resovoir, if the cap say under pressure then that is it and to add coolant to radiator you fill it thru the res.
Yes; it's on the coolant reservoir. The entire coolant reservoir on the Saturns is pressurized.
On a 2001 Saturn L-Series, the radiator cap is located on the top of the radiator itself. It is typically a circular cap that can be unscrewed for coolant access. Ensure the engine is cool before attempting to remove it to avoid injury from hot coolant or steam.
The radiator does not have a cap, instead, the coolant system reservoir is also pressurized and the pressure cap is on the reservoir.
The radiator cap is on the coolant reservoir, which is mounted on the passenger side fender for S series Saturns.
The radiator cap on a 2003 Saturn Vue is located on the engine's cooling system, typically at the front of the vehicle near the radiator. It is usually found on the top of the radiator or on the coolant reservoir, which is a white plastic tank connected to the radiator. Ensure the engine is cool before attempting to remove the cap to avoid injury from hot coolant.
