    ur electrition is right.........automatic fas is recommended in winter only for these small cars.now connect it directly.i too,hav faced this problem in my khyber.
    secondly,if ur heat guage needle raise more than half,,,its dangerous,below it ,its alright.
    i strongly recommend to connect ur fan directly bcuz its hot n u also use ac..........

    Hi
    what I could make out from your post is that: the temperature gauage is not showing any signs of car heating up, but once you open up your hood, it appears as if you have opened up a funace. Am I correct? If this is the case you must have your guage checked first. merely feeling the temperature using your senses might not be a good Idea. If the guage is correct, then you need not worry about much. Even getting the radiator hooked directly tot he ignition wont be necessary. good luck, rashid y

    Do the following:

    1. Get the radiator cleaned up and the radiator fins aired.

    2. Set the fan into direct mode and also do check for the fan relay if the fan speed is not up to the mark (electrician will recognize it better)

    3. If the fuel gauge is rising then it is ok. It is note worthy that Human Face is most sensitive in sensing heat or cold so donot try to feel the temperature of the engine on to your face.

    does the use of coolant in radiator help?

    I dont know why people recommend having the fan connected directly.

    Not a good idea on any car. The stupid electricians n mechanics tell u its useless to have a thermostat and the fan should be direct. Ask them a simple question: Why did the factory give the swithc then?? Imagine if the factory saves say Rs 100/- per car by not providing the switch, how much would it save per 10k cars???

    With the kind of cars turning out of factories locally, one can imagine that the factory people would be willing to save every penny from every possible thing. So the thermostat is not there for fun. Some may say 'sahab thanday ilakoon kay liyay hay!' They deserve a kick on thier butts as they should know taht the car is locally produced for local markets. If it was a self imported one we would have reason to believe him.

    Even in this particular case here connecting the fan direct would actually mask the other probs of maybe a semi chocked radiator/ faulty temperature guage etc.

    So where is the wisdom????

    Try the radiator servicing thing, and keep us posted on your progress.

    - remove thermostate valve .. if its still there,, or change it,, its probably rusted as i see you have not been using coolant.
    - radiator is clogged,, again by not using coolant.
    - probably engine block water passage also clogged.

    remedy.. have radiator and engine water passage washed,, by fresh water..if fresh running water is keeping engine cool then yr problem is half solved,,
    the problem seems water passage clogged,, somewhere.

    i do recommend dual barrel radiator,, but a good like new single barrel radiator will also work fine. (no dents in radiator).

    use a coolant in future

    direct the fan,, if not satisfied,, get a bigger relay / motor fan.. make sure there is no leak in water passage. if above water cooling system still not sufficient,, use synthetic motor oil.. to save yr engine from heat.
    Good luck ..

    in lahore ,, ask in bilal gunj,, for thick radiator.. i dont know if you can find for khyber,, but you can ask,,
    very important to have a radiator checked by a mechanic before buying a 2nd hand. sometimes minor leaks are not visible to people who are not good in judging a good radiator.,,
    but id prefare you have yr exiting radiator cleaned up before buying another and use it with coolant and properly working fan

    ideally the engine should reach its optimum tempreture as early as possible and remain at the reasonable tempreture range in all operating conditions

    thermosat and automatic fan are necessary to keep the engine at optimum tempreture

    the thermostat valve would not let the water circulate in the engine untill the engine has reached the optimum tempreture so never remove it

    the automtic fan only starts when the engine need cooling down so never switch to manual

    keeping the engine extra cool is no way recommended as at low temp there is more wear and tear and thats why its recommende to drive at moderate RPM(not speed) untill the engine reaches optimum tempreture

    other problmes associated include in winters ur heater wont work properly/ quickly , the engine will take longer to heat up both in winter and summer,


    pl understand these facts and then remove the problem not the things that are required for good engine health

    cleaning the radiator is a must if the water seems rusty
    use coolant always half half or 60:40 collant:water
    usually the raditor designed for the car is ok in all condition unless it has dents or extreemly dirty with oil / deisel spray usually done at services that clogs the radiator

    the fan spped may be enhanced with a relay it it is a old car
    with ac both fans usually run all the time in swifts so pl check if they start operating as soon as the ac is started

    good luck cooling down

    nascar:
    i understand why not to remove thermostate valve, i still have it in my car in month of May, because ecu determines fuel flow according to engine temp.

    but i have used a khyber7 years back, luckily that car never had overheat problem with or without a/c.

    here we are trying to reduce the engine temperature in a khyber with carby engine in month of May,,its was 43degree centigrade outside today. so practically speaking yr advice about leaving a thermostate valve in there dont have importance. yes once after heat problem is solved, and winter months approach,, good idea to put a new thermostate valve when its 15degrees centigrade or less

    I really respect your openion about tharmostat valve, even i am using it in my car. But you see its 95 model n must be on CNG, that hard for a 11 year old engine, and probably head must have been through many pressures and therfore gone a bit weak so, i recommended that.

    And i just recommended it for summers , not winters . nyways thanks for sharin your info

    @ levin

    i dont think 43C is too much for a engine

    as i know the thermostat rating is usually around 90-100C
    i.e afte this tempreture the valve opens and lets the water circulate

    and i may be wrong here but normal operating tempreture starts from 90C and varies upto 110C or more (i m not sure- can anybody do some net seaching for this - or guy with a european car may have a tempreture gauge showing degree C and tell us the range in C)

    so out side tempreture of even 60 C is not much for an engine.

    so if the cooling system is workng properly it should start cooling after its required not before and in any case if its ok no need to remove the thermo stat.

    the ECM in ur car would be getting the info from the temp gauge so thermostat or no thermostat it will work.

    but i strongly argue that thermostat is very neceessary and should be kept in almost all circumstances. but if u need a short term low budget solution then take it out for the summer or a few months

    I digagree with people who are telling you to bypass the fan relay. Just do the following and you will be fine trust me:

    1. Clean the radiator
    2. Use coolant at the recommended ratio for summers
    3. Make sure your engine is not retarded - if so advance it to the proper timing
    4. Check your temperature gauge and replace it if its faulty
    5. Check the thermostat valve which controls the water flow through the radiator
    6. Check your fan relay and replace if faulty - DO NOT REMOVE IT

    Maybe it is your imagination that the engine is hotter than it should be. Does the engine start knocking a lot when its hot? That's the first sign that the engine is over-heating.
    Speed thrills and kills better than anything else.
