    Default Xulfiqar bahi-- help regarding heater of corolla 96

    in summers my local AC mechanic took off the pipes of hot water , which are in the firewall that goes in the heater hose, for better colling of AC.
    now in winters i my self attached all the pipes according to the factory settings, the problem is that my heater is not giving hot air inside the cabin. car is fitted with auto fans and thermostat. i drove the car almost 50 kms and checked the pipes which were going inside the heater hose, there was no pressure of gas inside only in those two pipes , the pressure which generally develops in all radiators pipes when car is hot. all others pipes were having good pressure except those two the inlet and outlet of heater hose
    is there any possibility that heater hose might be air locked ??

    ur kind help is required, as i say u the original car guru .

    another problem
    my car is diesel and it starts easily when cold, but takes very long self if started when warm with out preheat glow plugs

    check that you have coolant flowing through them - both pipes should get hot with the heater at max setting, if its not then you need to see where the blockage is.

    In case of civic there is a valve inside the pipe which serves as an inlet to the heater core from the engine, the valve is operated by a cable which is attached with the climate control heat/cold selector lever. If the same valve is present in the inlet pipe of corolla then do check that.

    check the valve clearances, injection pump timing and nozzle break pressure. Why are you changing oil at 3000 kms?

    Answer 1 : you pipes have plastic plugs in them called "tikkian" remove them
    Answer 2 : FIP rotor needs polishing

    ^^ I hope you did not write FIP = Fuel injection pump.

    In that case the rotor would be rendered garbage, the rotor and pump head are replaced as a set never alone. It is also vital that the holding screws are torqued down evenly with a torque ratchet.

    Mineral Oil: 5000 km

    3000km once you have been driven in dusty areas

    otherwise you are burning $$$$
