    Default Civic 1997: Heating up.

    Dear All,

    The car is installed with thermostate valve and automatic fan. Now problem is that the auto fan start when the temprature guage is around 3 quarters or even more. is this the problem with the fan switch or the themostate valve? from last night i am running on direct fan and need to resolve the problem ASAP. Please help. even on direct fan and on bumper to bumper driving or on high steap the temprature still goes a bit up from half.
    One thing more i have installed the thermostate valve almost a month age before that there was no themostate valve installed. after installing i have to change the themostate switch once and now this problem occured. i think i should remove the thermostate valve.

    Regards

    Get your radiator thoroughly cleaned / serviced from a professional shop or buy a new one if the old one has bent/damaged fins.

    thank you.

    Get your fan auto first. Now open radiator cap and start car check for bubbles and is your car shorting water? Do check the fan switch it should start at half. Do keep the Thermostate valve installed.

    As already stated the fan is not working on half instead it starts almost 3 quarters or more up the temprature guage.

    Question Checks....

    A number of things you have to check:
    - Is water flowing in the radiator? Is it moving or still?
    If the water is still that means your water pump has expired. Probably its fins have corroded. Need to change it. If water is moving then it means pump is ok and the fault lies elsewhere.

    - Does the temperature stay in one position or keeps moving upwards?
    If the temperature stays in one position after the engine has been running for some time then it means the temperature has stabilized and you probably don't have to worry. But if it keeps moving up then you have to trace the fault. A leaky gasket could be one reason. Probably have to replace it.

    - Are there bubbles in the radiator or is the water bubbling when the engine is on?
    If there are bubbles in the radiator once the engine is running most probably the gasket is letting in air. Needs to be replaced.

    These are all assumptions based on my experience and I could be wrong. But just a guide for you.
    :-)

    Last night removed the thermostate valve. the fans is auto and starts at optimum temprature i.e when the guage is at half. what i assume the fault was in the themostate valve. it was not openning at the correct temprature and in return the fan was not starting at correct temprature.
    Is my understanding correct?

    The temprature of the car is fine from last night i have drove it aroung 25km in mix traffic and the temprature guage is at half or even low because i have removed the thermostate valve and fan is auto.

    thermostat switch problem. get it replaced,it is supposed to trigger the radiator fan at about half point or a little before mid point. thermo stat valve has nothing to do with kickin the radiator fan,it just keeps water flow restricted till the water temperature gets to a certain level. kickin the radiator fan is controlled with switch.

    as per my understanding unless hot water from thermostate valve touch the thermostate switch it will not start the fan. if thermostate valve opens up at a high temprature then the optimium then it will open at high temprature and thermostate switch will start the fan at that temprature.

    In my opinion you are thinking on the right track.

    You can check your T-stat by putting it in a bowl of water on the stove. The Thermostat should open just as the water is about to boil. If you have a temperature gauge, you can check exactly when it opens. It should be around 80 degrees.

    First you need to confirm that there is no air in the cooling system.
    Second check the thermostat valve with the Procedure in image below. The thermostat valve will have a number printed on it. This denotes the temperature at which the thermostat opens. Replace if it is not opening at the right temperature.
    Third check the fan switch (aka Engine Coolant Temperature switch). Procedure is in the image below.

    It could be air in the system, it could be thermostat valve or fan switch. Or it could be two or more things. You can only find out where the problem lies by testing each.

    Off the top of my head, I think its either air in the system or fan switch.
