some of the saturns have a thermostat that also controls the fan, so if the thermostat is bad the fan will be inoperable...others have a separate sensor..if the thermostate is the fan controler it will have a wire coming off of it, otherwise look for a sensor that goes into the water jacket or block of the engine, it will also effect your water temp gauge.Answersome of the saturns have a thermostat that also controls the fan, so if the thermostat is bad the fan will be inoperable...others have a separate sensor..if the thermostate is the fan controler it will have a wire coming off of it, otherwise look for a sensor that goes into the water jacket or block of the engine, it will also effect your water temp gauge. AnswerYes. The Thermostat controls the flow of coolant through the radiator. The fan controlls the flow of air across the radiator. They both work together to assure the engine is allowed to reach normal temperature and not get too hot. A working thermostat restricts flow through the radiator until the coolant in the engine reaches 195 F. It then opens just enough to let the proportion of coolant being cooled in the radiator control the engine temp to 195. The radiator fan is temperature controlled, it comes on when when hot and cycles off when it cools down. Normally it is off at highway speed because plenty of air is flowing anyway. When parked or in city traffic it cycles on and off, coming on more when the vehicle is standing still or moving very slow.
The most common failure mode for a thermostat is to fail open. In that condition the engine will take a long time to warm up. (The first thing most drivers notice is it takes a long time to get heat in the passenger compartment.) With the thermostat stuck full open the fan will seldom run. It just won't get warm enough to turn on, unless you are towing or climbing mountains on a hot day, or come to a sudden stop after driving on the highway. When parked or operating in city traffic it will not come on as often as it would if the thermostat was working.
The thermostat on a 1995 Saturn SL1 is located on top of the motor. The largest hose coming off the radiator will have to be loosened to access the thermostat housing on the motor.
Follow the upper radiator hose from the radiator to the engine and at the engine you will find a housing with the thermostat inside. When replacing it make sure the spring goes toward the engine.
Thermostat is located on the passenger side of the engine. If you look where the two hoses are going from the radiator and the resiviour this part comes out and the thermostat is located underneath.
Follow lower radiator hose to its end. Remove hose at this end. Use cardboard too (provided with new thermostat) to press in and turn counterclockwise to remove old thermostat. Use same tool to install new thermostat. Fill system. Don't worry about where thermostat is because you have a new one now.
sounds like a stuck closed thermostat. ^I agree. Wife and I used to one and that was a reoccuring issue with it.
Check the tension on the belt, it may be slipping. If tension is okay, you might need to flush the radiator or the entire cooling system.
If the electric cooling fan(s) are not coming on that may be the problem.
Thermostat bad or missing or engine not running.
It's actually easier to replace a Saturn thermostat than most other vehicles. Simply remove the thermostat housing and get a new one. The thermostat is molded into the housing. Remove the radiator hose to the housing, then remove the two nuts that hold the thermostat housing to the engine. You may need to work at breaking the housing loose since the gasket has probably seized to the engine. Simply clean off any left-over gasket, and put the new gasket and thermostat housing in place.
Yes! both the radiator and the hoses are swapable :) Just besure that if your vehicle has a automatic transmission the radiator has the automatic transmission cooling line fittings.
they are located behind radiator and intake muffler. there are a couple of bolts and they come out in sets of 2
Blown fuse? Bad fan motor? Bad temperature sensor?
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.
I had the same probl;em on my 1996 SL1. I found the bypass tube from the head to the reservoir was clogged and would not let water return to the reservoir. When I unclogged the line the overheating went away. I also had replaced the water pump and thermostat before without any luck. The clogged line was the culprit.
It is your fan. Disconnect it at the radiator,and run some jumper wires to the battery.I ran the wires through the sterring column on my 95 sl1 and installed a toggle switch. If it even tries to get over a guater hot,I flip the switch. It cools down instantly!
1) Defective water pump 2) Stuck thermostat 3) Broken positioning tab inside thermostat housing (located at engine block on front side under AC compressor, if you have AC).
There can be a number of reasons why an engine will overheat:A failed thermostatA worn out water pumpA clogged radiatorA blown head gasketYou'll need to narrow it down. There are a number of devices that can help you figure it out.
If you are certain that you have sufficient coolant, and the heater is not warming up adequately, check the thermostat and/or water pump. If the thermostat is staying open the engine coolant will not heat up enough to provide heat inside the passenger cabin.
Mostly untight hose clamps or a hairline crack on the radiator drives side. Coolant will also leak from a faulty water pump
timing for spark plug wires for saturn sl1 1996
I do not know about the SL1, but often there is a relay for high current circuits such as headlights. You could check for proper operation of the high-beam headlight switch at the excitation terminal of the relay and check for headlight circuit energy at the output on the relay.
yes that is my question
how do you line up timing chain on a 1993 sl1
