Have you checked the cooling fan relay? ? This is the child's wooden block size relay installed in the fuse/relay box in under the hood. If it is bad the fan will not come on even if all the other sensors and components of the system are functioning. Also, This cooling fan relay draws a lot of amperage which causes it to heat up. On my '92 SC2, I have learned that the contacts of the relay have become so hot from the high current they carry that the fuse box sockets overheat and deform. It became necessary for me to open up the upper and lower halves of the fuse box and install new conductors to restore good contact with the relay pins. If you find that your cooling fan relay pins are discolored and the plastic housing is slightly deformed around the pins, you are likely haveing a similar problem. For a while I was able to just slightly twist the pins of a new relay using a pair pliers so that they would make tighter contact in the deformed sockets of the relay box. Hope this helps, JB

Why does the needle on the coolant temperature gauge of a 1995 Saturn SL stay on the C?

The guage on the dash uses the ONE wire sensor... This is located in the block near the drivers side. Eric First check to see if you have coolant in the radiator. If there is no coolant you will not get any reading from the temperature sensor. If there is coolant then change the temperature sensor.

How many cooling sensors does a 1997 Saturn Sl have?

1 and the coolant temp sensor is located in the head under the upper rad hose

Where is the water pump to fill up in a 1996 Saturn sl2?

You don't "fill up" the water pump. The water pump is just a pump that moves coolant throughout the engine cooling system. You add coolant at the radiator or the coolant recovery tank.

What is the difference between the single wire and 2 wire coolant temperature sensors on a 1996 Saturn?

In most cases the single wire sensor runs a temp gauge or temp light. The double wire sensor feeds info to the vehicle's computer and operates relays for the cooling fans. This may or may not be the case for your Saturn.

What can possibly be the cause for coolant to overheat in a 1999 Saturn SCl?

Common for a cracked coolant temperature sender. Although there are many other possiblilites. Don't wait, get it figured out ASAP.

Why does a 1999 Saturn heats up to half way on temperature gauge then cools off to quarter when parked idling?

The 1999 Saturn S-Series engine heats up the coolant, the thermostat valve opens and the coolant circulates between the radiator and the engine. Then the radiator fans turn on to cool it back down. The fans are also turned on when the air conditioner is turned on to aid in cooling the radiator and the air conditioner condensor.

What does the indicator light on a 1994 Saturn SC2 with a low tank arrow pointing down and a temperature gage mean?

The light you are describing indicates low coolant level in the coolant reservoir.

Why is your Saturn coolant warning light on?

The reason the coolant light is on in a Saturn vehicle likely indicates a low level of coolant. Filling the receptacle should fix the issue.

Does the 97 Saturn SL2 have a radiator cap?

no, it's on the reservoir. Yes, the radiator "system" has a pressure-release cap located on the plastic coolant fill bottle. This bottle is an active part of the cooling system, and is where you add coolant to the system

What causes the temp gauge goes up on my 95 Saturn to stop lights only Checked the coolant and it's ok?

If the temperature gauge is rising when you stop at traffic lights then your electric cooling fan is not running. Most likely need a new temp. switch for the fan.

Your 96 Saturn is running hot after about 15 miles?

Causes of overheating: Low/no coolant; cooling fan relay switch/sensor faulty; cooling fan motor faulty; thermostat stuck in closed position; water pump faulty.
