Due to the constant motion and combustion in the engine, the engine produces very high temperature which has an adverse effect to its working. So to keep engines in the right working condition, scientists came up with a substances called COOLANT. Coolant basically is any substance that can reduce the working temperature of any component. NB; The working temperature of a car is between 80- 85degree Celsius. Causes of overheating 1. No water in the radiator 2. Minerals from the water has formed clogs in the water ways 3.  Bad thermostat 4. Faulty fan 5. bad hose Steps to adding coolants 1. Check manufacturer's manual for the right coolant to use 2.Open your bonnet and locate the radiator reservoir 3.Open the cap slowly 4.  Pour the coolant into the reservoir to the maximum point. Do not exceed the maximum point. NB ; you can pour only the coolant or mix it with distilled water (50/50)

When you see a this light on your dashboard ,your car is telling you that there is something wrong with your engine and it demands you to check it pretty fast. This can vary from emission system malfunction to misfiring of the cylinders to low fuel pressure and so on. In this article we will be talking about P0174. P0174 is the trouble code the OBD II would bring out when you probably notice that your fuel intake is higher than normal, although there are many causes of this symptom. P0174 means that the oxygen sensor bank 2 has detected too much of oxygen in the exhaust ( a lean mixture). Possible causes of P0174 1. Intake air leaks 2. Faulty front heated oxygen sensor 3. Ignition misfire 4. Exhaust gas leaks 5. incorrect fuel pressure 6. lack of fuel 7. faulty MAF, mass flow sensor. Possible Solutions 1. change the Air filter 2. Clean the MAF sensor 3. Check for leakages in the air system 4. Clean the injectors

An injector is a device in a vehicle that allows fuel or diesel enter into the intake manifold of the engine in the right proportion and time. When the a car is scanned with an OBD II and it brings out codes like P0300 to P0308 it shows that the car in question is misfiring. Engine misfire can be caused by any of the following ; 1. bad spark plugs. 2. dirty injector pumps. 3. vacuum leak in the intake manifold. 4. weak injector coil. 5. low fuel pressure.   Tools needed to clean an injector 1. a set of spanner 2. choke cleaner 3. a container lets get started ; 1. Remove the cover from the engine. 2. pull out the wires from the injectors and pull the injectors out of the engine, one after the other 3. use paper to cover the holes where the injector fits in. This will prevent foreign bodies from entering the engine while working on the injector. 4. put the injectors in a container. 5. cover the container half way and spray the choke cleaner into th...
