What is code U2107
Hi the codes are present , I have cleared them , and they come back , the 1482 , code seems to be for the radiator fan , and the code 2107 for electrics to my instrument panel I believe , because as I am driving the rev counter and speedo and oil , all the needles go to zero , they start working intermintanyly with the orange spanner light flashing on
Gas leak, engine light on
Gas or oil leak? Gas leak can turn the light on. Oil doesn't. Try to notice where the leak is under the car on the ground. Look under the car and see where the leak is on the frame. All this helps. Have the codes read.
My heating system doesn't work on dials 1-3, except 4
Hi thats the resistor heaterthat boken normaly they stop working on day you got no 1st speed and so on its under the dash on the passager side need a 7 32 socket and lot of patience good luck pierre thanks for using fixya
How much torque for brake pads
Torque wrench/torque not readilly applied.When putting the calipers back on the 2 attaching bolts,usually allen wrench type need only be snugged up tight as you can get them use a wrench for a little additional torque that is all that is needed to tighten sufficently.
Coolant leak
Obisouvly a leak somewhere.Would start with upper and lower radiator hoses with vehicle running and at normal operating temp.This will allow the cooling system to build pressure,look for signs of wetness at hoses as well as heater core hoses from water pump to usually the firewall where they go into the passenger compartment to the heater core.
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.
