Honda civic 2005 reducing coolant

[Salman922]

Though that is also not related to coolant disappearing problem but yes both should not start when ac is not running and car becomes hot, Only radiator fan should run. I think someone shortned control wires of both fans together so that when you turn on ac both fans get power and turn on preventing car from overheating. See if both fans run when you turn on ac. Similarly when radiater fan gets power both fans turn on as wires are probably shortned...

Yes sir, both fans start on ac and also when the radiator fans get power upon heat without ac

i have a 2.0D Saloon 2003 and Civic 2007, both with fan auto and thermostat installed and in both of my cars TWO fans work together, NOT separately. although in corolla fans turn on at a lower speed when engine is cool and i turn on AC while in civic the speed is constant.

does coolant boils in reserviour bottle?? this gen of civic have air trapping issues

[shahjaha.jhinkur]

Well, the car is 10 years old so you cannot expect it will be good as new. I believe the radiator has some fine cracks. The leakage will not be visible but during driving (while the temperature gets hot), it leaks. You also have to check the hoses and radiator cap. My prediction is you can use the radiator about a few months more before it gives way. Try to look around for a new radiator and get it replaced if the situation gets worse.

Is there a relationship between the oil viscosity and coolant reduction?????

No relation

You should be using the correct radiator cap in working condition. The spring losses its tension over time engaging earlier than required pushing more coolant in to the overflow tank. Post the pressure rating on ur cap.

It should be a 1.1 bar cap. Replace it with OEM.

Going deep into the technical details of viscosity some relation could be built in terms of energy wastage but apparently there is no direct link between the two...

Today I drove my car continuously for 2 hrs with ac on. Upon reaching home, I had witnessed the upper hose pipe leaking coolant from the engine side, not the radiator side. Is it the fault of the hose pipe or the engine, because I had seen the leakage the first time after driving continuously

Radiator hose pipe leakage is not something uncommon. Get it replaced. Just make sure the place where you connect hose pipe to the engine is not corroded. I have seen coolant leaking from joint due to this even if the hose pipe is in good condition...

exactly the same case sir, leakages are seen on the joints. I have changed the clips today, they seemed a bit loose. the hose pipe looked fine

I hope your problem would be solved by this...

These are the 3 places where the leakage is visible to the eye. the leakages from the hose pipe does not seem that serious, but leak shown in the first picture is giving me the chills. It seems to be leaking from the head block. What should I do now????

plz help bhaiyon

[arzaam.bhatti]

you using tap water? as leakage color is brownish, if it was zic coolant it should be green residue. i am not ver familiar with honda engines, the leak int he first could be hose pip erooded on the joint, though unlikely as it seems fine, it could be leaking from the flange where it connects the head or the thermostat housing if its present in that place. it cant be leaking from the actual engine block or i dont think you should be worried about a crack in the head or block as otherwise you would be loosing oil or compression as well.

[Xulfiqar]

your throttle body heating pipes are missing their clamps, buy a couple and tighten them up. As you have been running tap water to cool down your engine there is a very high chance of those little pipe nipples being corroded and leaking from the head.

[NiGhTShAdE]

Go for screw clamps(common ones that are avaiable in market). They can be tightned to bit more extent though their negatve point is that they can be open and closed for less number of times than these tensioned clanps...

Xulfiqar bhai, the previous owner was using tap water. Upon reading ur comments I had instantly shifted to zic coolant. Got the radiator serviced and poured zic coolant

No bro, its on zic coolant. There is some green element present in the rust too
