Does a Chana Star 1000cc come with a new water pump?
Small wonder you are confused. The possibilitiess are so complex it would require a professional mechanic to narrow the diagnosis down. Here is a very long list of what might have to be checked otherwise.
Regarding the thermostat housing, its removal could impact engine temperature regulation. Running the fan continuously helps, but the underlying issue persists.
Step by step:
Fuel Delivery Issues:
Ensure that there's sufficient fuel reaching the engine. Check the fuel pump, fuel filter, and fuel lines for any blockages or leaks.
If the fuel system is compromised, it can lead to power loss and stalling.
Ignition System Problems:
Verify the condition of ignition components: spark plugs, ignition coil, distributor, and spark plug wires.
Faulty ignition parts can cause intermittent power loss and starting issues.
Electrical Connections and Wiring:
Inspect all electrical connections related to the ignition system, including ground connections.
Loose or damaged wires can disrupt the electrical flow and affect engine performance.
Air Intake and Air Filter:
A clogged air filter restricts airflow to the engine, leading to poor performance.
Check and replace the air filter if necessary.
Throttle Position Sensor (TPS):
The TPS monitors throttle position and communicates with the engine control unit (ECU).
A malfunctioning TPS can cause power loss and stalling.
Idle Air Control Valve (IACV):
The IACV regulates idle speed. If it's faulty, the engine may stall or struggle to start.
Clean or replace the IACV as needed.
Vacuum Leaks:
Inspect vacuum hoses, gaskets, and the intake manifold for leaks.
Vacuum leaks disrupt the air-fuel mixture and affect engine performance.
Faulty Sensors:
Modern engines rely on various sensors (e.g., crankshaft position sensor, camshaft position sensor) for smooth operation.
Use an OBD-II scanner to check for error codes related to sensors.
Compression Issues:
Low compression in one or more cylinders can cause power loss and starting problems.
Perform a compression test to check cylinder pressures.
Starter Motor and Battery:
Ensure the starter motor engages properly and turns the engine over.
Test the battery voltage and connections.
Exhaust System:
A blocked or damaged exhaust system affects engine performance.
Inspect the exhaust manifold, catalytic converter, and muffler.
Engine Control Module (ECM):
If other checks don't reveal the issue, consider examining the ECM for faults.
