2004 pontiac sunfire pcp valve

SOURCE: speedometer and tachometer stopped working

If the speedo isn't working properly, the first thing to check is the output speed sensor wires on the rear right side (near the bar code) of the tranny case. Follow the wires and make sure it hasn't been cut, pinched or shorted.
If all is well there, take the output speed sensor off. Watch out cause you'll get wet with tranny fluid (Dexron 6). (Be ready to plug it up.) If there are no metal chips or debris on the magnet inside, check it with an ohmeter on the two pins to see what the reading is. It should be around 6 to 10 ohms. If it's not steady, get a new one. Make sure the pins are clean on the connectors.
Apply some white or build grease around the shaft and "O" ring and re-install. Don't overtighten. The bolt is a "tap-tite" and should need only about 5 or 6 ft/lbs torque. (Run it in and give the bolt a quarter turn.)

Hello oldiro: My name is Roger and I can help. From under the vehicle look up between the transmission and the side of the block. Mid motor above the pan rail there is a bolted in sensor. This should be the crank sensor.It will have two wires plugged in to it. Please rate this answer as this lets us know you received the information you asked for. Should you need further help please just ask. Thank You for using FixYa. Roger

If it's a ticking noise that speeds up with the speed of the engine, it's a worn valve lifter.
You can try tightening it down by taking the valve cover off and tightening the bolt on the rocker arm, but don't tighten it too much, you will end up with other problems.

Just take the bottom hose loose and flush away.

SOURCE: Were is the thermostat located in a Pontiac Sunfire 2000?

Hi:
Your thermostat is located under the thermostat housing, which is what the upper radiator hose clamps to on the top of your engine. Basically, you need to start with a cold engine, drain your radiator, then unclamp the upper radiator hose from the engine. Remove the bolts from the thermostat housing, and gently tap on it to remove it. clean up the mounting surfaces on both the engine and the housing, and install a new thermostat, and new gasket. tighten to proper torque, reconnect the radiator hose, then refill up the radiator and cooling system.
