Question about 2005 Chevrolet Monte Carlo

1 Answer

2000 Monte Carlo SS (89,000 mi)

My 2000 monte Carlo SS is running sort-of sluggish. I found some slushy brown stuff in the engine coolant tank. It had already run through the radiator. Then I noticed that my engine temp gauge wasn't working, and the fan ran really loud, and conituously. Then a few days later, the temp gauge worked again, then went back off and the check engine light came on. What is going with my car?

That slushy brown stuff is signs of a blown head gasket. Have a code scanner hooked up to find out why the light is on, it will probably show coolant temperature sensor. Just out of curiosity, check the pvc valve (if your car has one), and see if it's clogged. If it is replace it, the crank case is not getting ventilated.

2001 monte carlo ss. has heat but heat gauge does not work and cooling fans do not cycle just keep running


Hi, check the connection on your temperature sensor. If the connection is good, replace the sensor. The cost is about $11 at autozone. The sensor is located at the back of the engine, near the transmission. See pictures below. Use some water pump sealant on the threads when installing the new sensor. Please let me know if you have any questions, and thanks for using FixYa.

My 2000 monte carlo ss with a 3800 engine tends to start and stall about six times befor running, I pulled 3 codes 0108, 0404, and 1404 from the the computer .


I believe the codes are emmission related. I would have the fuel pump pressure checked. The fuel filter and fuel pressure regulator seems to be the failrue. The restarting of the engine several times is making the system build up enough pressure to start running . I would take to a shop to have the fuel pressure checked.

The fuel filter is located in the pressure line that runs from the fuel tank to the engine, near to the fuel tank.
Keep the engine off for few hours before replacing the filter, to get rid of some pressure in the lines.
