20 Most Recent 2007 Pontiac G5 Questions & Answers


Very often the cause of coolant being expelled from the reservoir is due to a faulty head gasket leaking compression air into the water jackets. When the engine stops circulating the coolant, with the water pump, the bubbles collect together in the radiator as they rise to the top. Then the hot compressed air passes through the pressure relief valve (often radiator cap) and enters the reservoir, thereby blowing coolant out of the overflow tube.

I had this problem once with mini-van that I owned and it turned out that the grill on the outside, at the base of the windshield had plugged with tree debris and the water could not find the drain hole so it backed up and came in under the dash and filled the cavity where the blower motor for the heater sits.

I cleaned that out, pulled the blower motor and dried the tub it sat in which by then had mildewed, then put it all back together and things were fine. The blower motor had shorted out by the way so I had the fun of buying and installing a new one.

The speedometer not working wouldn't be caused by an input sensor . The VSS - vehicle speed sensor is a direct input to the PCM , the PCM shares is info over the GMLAN data bus.
Speedometer
The instrument panel cluster (IPC) displays the vehicle speed based on GMLAN serial data message from the body control module (BCM). The BCM receives vehicle speed data from the powertrain control module (PCM)/engine control module (ECM) via the GMLAN serial data circuit. The speedometer will default to 0 km/h (0 mph) if:
?€¢
The PCM/ECM detects a malfunction in the vehicle speed sensor circuit.


?€¢
The BCM detects a loss of GMLAN communications with the PCM/ECM.


?€¢
The IPC detects a loss of GMLAN communications with the BCM.


The only way to diagnose these problems is with a factory scan tool , this will check inputs an outputs at the PCM an BCM to the instrument cluster . This avoids guessing an playing the parts game. Your best bet would be to take your vehicle to a qualified repair shop .
Same thing with trans not shifting out of first gear , could be a shift solenoid ! Does it shift manually , moving gear selector through the gears ?

No it does the opposite Gale as it puts more strain on the engine to drive the compressor.

You need to make sure the radiator is full of coolant with no air pockets. People get confused with filling the radiator and filling the overflow reservoir. There is a cap on the radiator, remove it and top it up, run the engine and keep topping it up. Also make sure that your HEATING in the car is on FULL heat and FULL fan. Squeezing the radiator hoses will help to dislodge air. The level will rise and fall when the thermostat opens up. Rev the engine a bit, top up one last time and when there are no bubbles, replace the radiator cap. Turn the engine off and then top up the overflow reservoir. Use antifreeze mixed to the manufacturers specs, usually 50/50.

Have a look at some of these videos.

Key fob or not, that vehicle has an antitheft system on it. I'm sure if you look at your key there is a PK3 stamped in it. Or a plus sign (+) or two circles or something. oo. The security light is due to the failing of this system Nothing else. It's not the car alarm or weird ideas people get about windows being down or anything like that. It is solely there to tell you that the security is failing. Eventually that car will stop starting all together. You will need to get that fixed before it strands you somewhere. It is also possible to bypass if you have no fears of auto theft. Will save ya $500 or more just to bypass it.

The reason your anti-theft is active is the new column has a different key than your original. The chip that is in the key is different than the one that is suppose to go to your vehicle. You need to order a new lock cylinder from your local GM dealer for your VIN number.

The tail light lens usually has to be removed on most vehicles. It is held in place by plasticor metal nuts in behind the carpet liner behind the light. Remove these nuts and the lens should pop out to reveal the bulbs
