How do I change a heater core on a 2008 pontiac torrent


Your best bet would be to take your vehicle to a qualified repair shop ! You'll have to Recover the refrigerant from A/C , drain the coolant .
Remove the evaporator outlet hose and liquid line nut from the thermal expansion valve (TXV).
Remove the evaporator outlet hose from the TXV.
Remove and discard the sealing washer from the evaporator outlet hose. Refer to Sealing Washer Replacement .
Remove the evaporator outlet hose and liquid line from the TXV.
Remove and discard the sealing washer from the liquid line. Refer to Sealing Washer Replacement .
Install a protective caps to the evaporator outlet hose and the liquid line to prevent contamination and desiccant saturation.

Reposition the heater outlet hose clamp at the heater core.
Remove the heater outlet hose from the heater core (1).
Reposition the heater inlet hose clamp at the heater core (2).
Remove the heater inlet hose at the heater core.
Plug the heater core and the evaporator core with clean towels to prevent spillage when the HVAC module is removed.

Remove the HVAC module seal nuts from the front of dash.
Remove the instrument panel (I/P) retainer. Refer to Instrument Panel Retainer Replacement .
Remove the shift control bracket. Refer to Transmission Control Replacement .

Remove the center floor air outlet duct by sliding the duct forward then up at the rear.
Remove the center I/P air outlet duct retainers from the instrument panel tie bar.
Remove the center I/P air outlet duct from the instrument panel tie bar.
Remove the instrument panel tie bar. Refer to Instrument Panel Tie Bar Replacement .
Disconnect the blower motor electrical connector from the I/P wire harness.
Disconnect the blower motor control module electrical connector from the I/P wire harness.
Disconnect the HVAC module electrical connector from the I/P wire harness.
Remove the HVAC module from the vehicle.

Were is expansion valve in a 2002 Chevy trailblazer in the truck


Are your asking about TXV valve thermal expansion valve for A/C system ? If you are ,yours doesn't have one . Has an orifice tube , The orifice tube is located in the liquid line between the condenser and the evaporator !
The orifice tube is the dividing point for the high and the low pressure sides of the A/C system. As the refrigerant passes through the orifice tube, the pressure on the refrigerant is lowered. Due to the pressure differential on the liquid refrigerant, the refrigerant will begin to vaporize at the orifice tube. The orifice tube also meters the amount of liquid refrigerant that can flow into the evaporator.
Unless you are referring to the auxiliary A/C system for the back of the vehicle , it uses a
The rear TXV is located at the rear evaporator inlet. The TXV is the dividing point for the high and the low pressure sides of the rear A/C system. As the refrigerant passes through the TXV, the pressure on the refrigerant is lowered. Due to the pressure differential on the liquid refrigerant, the refrigerant will begin to boil at the expansion device. The TXV also meters the amount of liquid refrigerant that can flow into the evaporator.

2006 impala under 2000 rpm car feel lost of power


That could be exactly what is happening. You need a professional level scan tool capable of accessing all modules to get any stored codes. Not all codes put a light on.

Wht is a TXV


Simply it's a valve in a refrigeration system that controls or meters how much coolant is allowed into the evaporator.
A thermal expansion valve (often abbreviated as TEV, TXV, or TX valve) is a component in refrigeration and air conditioning systems that controls the amount of refrigerant flow into the evaporator thereby controlling the superheating at the outlet of the evaporator. Thermal expansion valves are often referred to generically as "metering devices".
A thermal expansion valve is a key element to a heat pump; the cycle that makes air conditioning, or air cooling, possible. A basic refrigeration cycle consists of four major elements, a compressor, a condenser, a metering device and an evaporator. As a refrigerant passes through a circuit containing these four elements, air conditioning occurs. The cycle starts when refrigerant enters the compressor in a low pressure, low temperature, gaseous form. The refrigerant is compressed by the compressor to a high pressure-and-temperature gaseous state. The high pressure-and-temperature gas then enters the condenser. The condenser precipitates the high pressure-and-temperature gas to a high pressure liquid by transferring heat to a lower temperature medium, usually ambient air. The high pressure liquid then enters the expansion valve where the TX valve allows a portion of the refrigerant to enter the evaporator. In order for the higher temperature fluid to cool, the flow must be limited into the evaporator to keep the pressure low and allow expansion back into the gas phase. The TXV has sensing bulbs connected to the suction line of the refrigerant piping. The sensing bulbs give temperature readings to the TXV to adjust flow of refrigerant.[2]

2006 impala transmission replaced but no indicator


Might flash computer. Sounds like security is locking ignition out thinking something was stolen. This happens when car parts are changed sometimes.

Hello had the same problem in my 2006 Isuzu I-280 I needed to
replace at this moment the Evaporative Valve Soleniod which is instaled next to the Vapor Canister. It is mounted on the frame behind the gas tank you will have to move the spare tire out of the way one bolt holds it in place this is where the canister is and the valve is mounted on the canister this is where it is mounted on my 2006 I-280. If you need to replace the solenoid and you can't find the original Isuzu part, you can ask for the 2006 Chevy Impala V-6 3.5 Purge Valve Solenoid. It is the same piece. The old Evaporative Vent Valve Solenoid has a number part PA-GF30, and it is the same part number I found in the new Chevy Impala Evaporative Vent Valve Solenoid.
