The location of the censor for the radiator cooling fans
Cooling fans should run when the A/C is on no matter what the temperature is, if they don't look for a wiring or fuse fault. there are no sensors common to the fans. The computer turn the fans on when the vehicle's temperature rises.
Replace a fuse cigarette lighter
The fuse box is under the hood on the driver side top. And there is a intireor fuse box in the driver door post. The fuse box covers have the diagram and position of the fuses on them.
Why am I losing coolant with no leaks, I just replaced my head gasket?
Deff check what answer 1 said. But let's try to assume it's something easier. Sometimes it's hard to get the air out of the line when you run out of coolant. There is a bleeder that will help, turn the heat on to fill up the heater core. It also helps to jack the front end up and keep massaging the cookant hose. It also helps to pull your top radiator hose off and directly fill it up.
Why is my car losing coolant?
If there are no visible leaks, and if the vehicle has 50K or more miles, it could be the water pump. Water pumps can leak small amounts of water out the "weep hole" while running (this is to indicate wear and need for pump replacement before failure), but seal up when shut down. This leaking water will often evaporate on the block or trail under the vehicle. Sometimes, if you look at the underside of the hood just above the serpentine belt, you may see a vertical discolored stripe on the paint or insulation. This may be coolant that drips onto the serpentine belt and is flung upward., but this is not always the case. Usually, if the week hole is leaking, if you can get a visual look at the bottom of the water pump pulley (often hard to do), you may see some indications of coolant seepage.
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.
