No heat in 2007 chevy colorado new thermstat
Sorry to say this is one of GM's unreported and non recall problems..one fairly easy to fix the other requires dash removal..the sensor that call for heat/ cool is bad or the operating mechanism is broken..not allowing the door to open allowing the heat to flow into the cab..is located on the air box under the dash behind and below the radio it contains the heater and air condition Cores ..with a little effort it can be seen operating when the switch is pushed on off for heat..if it doesn't operate the activator is bad and can be replaced with some effort..but if it operates but does not open the door then the internal door operating arm is broken..Dash must be removed to get at it...Utube asking about GM no heat/ should have a video...sorry but know because I have a 2093 Sanoma with the same problem..good luck..
Chevrolet spark stalled and at times wont start or idle but cranks
Some potential solutions:
EGR (Exhaust Gas Recirculation): You mentioned that you cleaned the EGR, but it's still showing as a fault. The EGR system recirculates exhaust gases back into the intake manifold to reduce emissions. If the EGR valve is malfunctioning or clogged, it can affect engine performance.
Here are some steps to consider:
Check for Vacuum Leaks: Inspect the vacuum lines connected to the EGR valve for leaks or cracks. A vacuum leak can disrupt EGR operation.
Test the EGR Valve: Use a vacuum pump to check if the EGR valve opens and closes properly. If it doesn't, consider replacing it.
Clean the Intake Manifold: Sometimes carbon buildup in the intake manifold can affect EGR flow. Clean the intake manifold thoroughly.
Thermostat: You've already replaced the thermostat, which is good. A faulty thermostat can cause overheating or poor engine performance. Make sure the new thermostat is functioning correctly.
System Voltage Low: This could be related to the charging system (alternator, battery, or wiring).
Here are some steps to troubleshoot:
Check Battery Voltage: Measure the battery voltage when the engine is off and when it's running. It should be around 12.6V when off and around 13.8-14.4V when running.
Inspect Alternator: Ensure the alternator is charging properly. If it's not, consider replacing it.
Check Grounds and Wiring: Loose or corroded connections can cause voltage issues. Inspect battery terminals, ground connections, and wiring.
Idle Issues: If the engine won't idle properly, consider the following:
Idle Air Control Valve (IACV): The IACV controls idle speed. Clean or replace it if necessary.
Throttle Body Cleaning: A dirty throttle body can affect idle quality. Clean it using throttle body cleaner.
Vacuum Leaks: Check for vacuum leaks around the intake manifold, hoses, and gaskets.
Timing Chain: The B12D1 engine uses a timing chain. However, if it's stretched or worn, it can cause issues like poor performance or stalling. Consider having the timing chain inspected and replaced if needed.
Remember that diagnosing engine issues can be complex, and it's often best to consult a professional mechanic or use diagnostic tools.
Hi how to set a timing belt tensioner pulley when replacing 2011 Chevrolet aveo
Tensioner pulleys are designed to be 'Self Adjusting'. These pulleys are on spring loaded arms so they automatically push against the belt keeping it tight. You use a socket or a spanner to swing the pulley arm back against this spring.
*Note* This is a powerful spring so BE CAREFUL when your working on it!
A lot of these tensioners have two small holes to help with installing a belt. When you swing the tensioner arm back these two holes line up with each other. You can then slide a hex key, or something similar, through both holes and it holds the arm back giving you space to get the belt on.
*Caution* When your ready to release the tensioner DO NOT just pull the hex key out!! With the socket or spanner you used to swing the tensioner arm back push the arm against the spring again, carefully pull the allen key out then Carefully release the pressure on the spring so the pulley sits correctly and tensions the belt.
How to remplace the knocl sensor wire
I'm guessing you mean knock sensor wire. If you need just the end of the wire you should be able to order a pigtail from any parts store and just but connect it on
