    Hi there I've had my Honda 2.4 i-VTEC now for about a month and I've driving it it's a brill car.

    Only thing thats concerning me slightly is the engine fans they seem to kick in very quickly and seem to stay on all the time.

    Today I started her up in the snow and the fans started up about 5mins after starting up.? Is this normal or is there something wrong? All fluids and oil are tip top

    Any insight and help would be great

    Cheersvpeople

    The fans your hearing are for the climate control.

    If you switch the climate control off and the car is cold your will hear the fans go off.

    So maybe today you didn't have climate control or A/C switched on and the fans kicked for engine cooling instead.

    Hi thanks for the reply

    The fan comes on wether the climate control is on or not!

    And is it normal for the engine cooling fans to kick in so quickly?!? Even from cold start?

    Ok try this get the air con to the lowest temperature, push auto open the bonnet check the fan is working one should be on when the aircon compressor kicks in .. then when the car is at normal operating temperature the other one should kick in.. that should put you at easy and identifying which one is for which function.

    However.. I have seen this issue before on a Tourer Type-S and found the radiator matrix coated in sand and dead flies.

    using a garden hose with very low pressure go via the front grill and lower grill to remove the debris, you will find your aircon working better too.

    When was the coolant last changed in your car inspect the rad cap seal too.

    Hmmm does sound quite quick but an idling engine can got hot very quick. Check the temp gauge next the same happens, you should find that the engine is up to normal temp hence why the fans have kicked in.

    you will prob find its the air con condensor fan that is working, the radiator fan shouldnt kick in untill the coolant temp is approx 80 - 90 oC which will take longer than 5 mins at idle from cold. make sure you turn the climate controll off completely and re-check. if you are still a little unsure i reccomend you have a honda garage/specialist take a look and put your mind at eaise.

    I've got what sounds like the same issue.

    I'll check if the AC is on tomorrow.

    Either way, the car is getting a major service, including coolant change, transmission fluid change and brake fluid change in the coming week.

    Will post up results after checking.

    Just checked and it was definitely the AC fan! Feeling a bit sheepish! :Aghast:

    The AC needs to actually say OFF, sometimes neither on or off are selected which by default means on.

    Thanks all and problem solved.
