Diagnosis and troubleshooting of engine overheating

Engine auto diagnostic tool overheating is without a doubt a vicious failure, which immediately harm the engine, and in extreme instances can cause catching or strain in the piston and also the cylinder. So, the moment the engine overheating needs to be based on its distinct manifestations, exact diagnosis and timely exclude.

When all of a sudden overheated

Cars in operation, inside the case of your cooling program has become great, in the event the engine is abruptly overheating, mainly you can find basically the following:

1, the cooling method is really a significant leak coolant and overheat. On this regard, might be right with the observation of diagnostic and troubleshooting.

2, pump failure with the cooling water cycle interrupt and lead to the engine to overheat. Then could be made use of for the touch approach to diagnose the unique signs and symptoms of the engine temperature is high, when the radiator, especially its lower temperature is decrease. Within this regard, the response for the water pump fix or replace the water pump.

3, the broken water pump belt and overheating. The cautious servicing personnel or drivers could be learned through observation ammeter dynamic driving directions to discharge or charge indicator lights whilst the engine overheating, broken water pump belt.

4, the Launch & X431 series the Thermostat main valve off and stuck within the inlet pipe, hinder large circulation of cooling water, the engine water jacket pressure increased rapidly when the pressure reaches a certain level (large), the cooling water impulse catching the main valve to change position, conducting large circulation waterway. At this point, the boiling water with a lot of pressure impulse radiator cover appear strong "boil" phenomenon. This failure should change the thermostat.

Lack of cooling water overheating
Cooling water water shortage You will discover two scenarios: cooling water leakage or evaporation, water capacity is lower than the standard capacity.

1, the operation with the cooling water consumption excessive overheating. This shall check:

(1) water tank filled with water after, idling the engine, check the radiator, water pump the scuppers and Cooling ministries leakage phenomenon, if it really should be excluded;

(2) whether there is water from the check of the crankcase oil. Should the oil in water content response to engine the disintegration overhaul;

(3) Check whether the exhaust pipe drainage phenomenon. If so, it might be the cylinder pad washed out, so the water jacket and cylinder collusion. This needs to be checked and replaced the cylinder head gasket.

2, Cooling water Launch X431 GX3 capacity is lower than the standard capacity and overheating. The inspection methods:

(1) scale excessive. Primarily during the long-term water as the coolant from the engine, as the mileage increases, the water in contact with the cooling water jacket wall, the cooling tube on the scale will be gradually thicker, especially from the higher temperature portion. This makes the cooling surface of the cooling process will seem to have a layer of insulating material, difficult time to disperse the heat generated by the engine for power and overheating. Excessive scale, the choice from the scale cleaning agent, in accordance with the directions on the operation method to get rid on the scale.

(2) The tank is clogged. There was a liberation CA1091 car, often overheating. Capacity check, found far below the standard capacity, in the demolition of your water tank, the tank heavy original tank sludge, scale, yarn and other debris, a lot of your core tube blockage, clear fix overheating disappear.
