After letting the car sit for a couple of days, I checked the radiator fluid level, it was way down. May have been an air lock or something that finally settled out. After filling the radiator, then the reservoir, I started the car, (started right up), I let it idle for 15 min constantly checking the temp gauge, it went to just under a half, and stayed there, so I took it for 5 mile ride at 45 mph and the gauge needle never moved. The engine light has not come back on, the car starts right up, and seems to run better. I will check the miles per gallon on the next 2 fill ups to see if that also improves. I thank all of you on this message board for you support. Who would have thought a $23 part would cause so much issues.

Same original thermostat in car, never changed, never had problem with it.

The one behind the engine under the manifold, has a plastic covered plug 2 blades, SU4258 Duralast part number

finally after installing the knock sensor, I was able to drive down to local auto zone to have the ODBll scan done. It turns out that the coolant temperature sensor was bad giving me the engine light. I replaced the sensor and drove it 15 miles, no problems. On the way back from work, I noticed the temp gauge go from below mid to the highest range in seconds, I pulled over, and checked the radiator res, it was ok, the took a towel and opened the radiator cap, radiator was full. I started the car back up, no issues starting, the engine light was off, no other warning lights on. The temp gauge rested on slightly over 3/4 the rest of the way home. I removed the sensor and returned it back to the store and swapped for another. I installed it and and test drove the car aprox 4 miles, the temp gauge went up to the highest point and then lowered to over 3/4. There are no radiator leaks, car runs fine, and starts up fine, no check engine light. Am I doing something wrong? Will the temp settle back after awhile?

Yes, and recheck it to make sure it is still tight to spec. What is weird is that sometimes I have to put the pedal to the floor and hold it there when starting until it catches and immediately back off the pedal as soon as it starts, almost like it is flooded.

Thank you, I had only replaced the key and balancer and checked to make sure it did not move at least every 3-4 weeks. The keyway on the shaft was reamed a bit, but I was able to get the key and balancer on snugly. I did not realize this would affect the timing as it only connected to the belts for alternator and a/c unit?

Thank you, I do have the engine light on, it would go out after unhooking the battery but come back on after a while. When my son had the subie, he had the belts come off, I discovered that the crank pulley/harmonizor was crooked, appears the key was mashed when pulley put back on after the repair shop put the new timing belt in. The pulley was wobbling and belts fell off. I replaced the pulley but did not replace the crank sensor. I did try to pull it but it did not budge and I was afraid I would snap it off in the engine so I left it alone. It more than likely needs replacing, but would it cause the issues I'm having?

I have not checked the codes because this 1995 was manufactured in early April and as far as I can tell, there is no place to hook up a computer to see the codes.

Yes I had unplugged and replugged a couple of times to rule that out.

Hello, I own a 1995 Subaru Impreza that had been rear ended quite awhile ago. Ever since then, the gas gauge has been faulty, never reaching full and going below E with at least a quarter tank of gas left. I realize that the gas sending unit probably needs replacing. But occasionally, the car would not start, it would turn over, but not catch. I would wait 15 minutes, then it would start right up. The plugs and wires were changed, timing belt and water pump changed, still would occasionally not start. So I replaced the coil. Now the car starts terribly. I cannot touch the gas pedal, it will start slowly then eventually chug then run ok. It also does not seem to have any power until warmed up, aprox a few minutes. At first I thought spark, then I'm thinking fuel is too much choking the engine. Just not sure. Could the gas sending unit cause this? Please help, thanks
