Do make sure if you are going in for aftermarket coolants other than OE then you buy a good quality brand like Motul, Castrol, Valvoline etc and not local ones and use them as mentioned in their respective packs as some mechanics would misguide you saying use full coolant instead of mixing it with water when the pack would mention just 1part to 3parts of water in which case it might be harmful and not perform cooling operation as required.

Default Hi!

Gauges can be misleading !

My gauge usually indicates at the 50 % (1/2) mark. I was advised to check the the car checked in case it goes to the 75%(3/4) mark - thumb rules of mechanics - I guess.


I was also told that the thermostat would operate at around this point to bring the radiator into the cooling circuit - something about a signal to the ECM to go into the close loop mode. Is it correct?

So i guess nothing to worry about but anything more than that then do get the coolant changed or check for leaks, sometimes it might not be a visible leak and the coolant might be trickling away slowly somewhere unnoticed.
i believe it is 1/2 even on an open stretch. having said that it is also quite hot these days. let's see - i guess if i notice it rising above that then i will get it checked. if not then i'll have it replaced/checked in the next service.

Bro dont worry about it too much, if ever it goes more than 1/2 and stays there in normal conditions then you need to worry.
Just get leaks checked and coolant level up to prescribed limit, thats it!
Drive with a "COOL" head and that will keep your ride cool!!

I thought the cooling circuit was already a closed loop one.

Whoops - guess I didnt put it clearly!!

The cooling system is a closed loop one - the radiator comes in the cooling path after the engine reaches a preset temperature. The thermostat bypasses the radiator till this temperature is reached.
( Did this research after my Dad complained that the engine gets heated up fast - his 96 esteem supposedly does not have this !!! Saw all the cooling paths after my diverter valve failed and I had to get it bypassed.)

From what I`ve read and been told, the ECM would go into the closed loop mode after this thermostat operates. That is what I meant by closed loop operation.

Ya i guess that how all the newer models function now.

Guys, the Ford dealer supervisor here said that we never have to use other coolant other than Ford recommended lubricant as it will affect the ECM. He has flushed out the green lubricant which I had filled in and then he filled it with ford recommended lubricant and said he will give a guarantee of 20k kms (till then coolant replacement is not required). Need to check this anyways...

I think it is a nice drive. You are right. These volvo guys drive very fast and whenever I will be driving in night I make it a point that never to give chance to these guys to overtake as we will never know when these guys will apply brakes and if they do, these buses tend to stop completely. The people behind will have a hard time brajing their vehicles.

I was told the same thing, but i figured out it was just another excuse for them to add on Rs900 to the bill and their coolant did'nt last me 5000Kms.

i checked the coolant level today and it was PRETTY low. the last few days she was heating up pretty quickly with just a few mins of driving with no traffic even in the night. now everything's ok. i went to the office this afternoon in scorching heat and the gauge was showing just around 1/4 which i guess should be normal most of the times even when it's a bit hotter.

A) It will not affect ECM, yeah maybe for indian condition ford might be using a diff/better grade coolant. Color is diff if i remember correct, but that doesnt mean it will affect ECU, rather car might run a lil hotter.
B) Regular coolant change interval is 20k kms or more, with top ups in between if required.

Hi,

I recently bought a 2004 1.6 nxt.Of late though, i noticed that there was a considerable decrease in the coolant level.In the last three days the coolant is completely drained out.Now every time i add coolant it gets drained out within minutes.Also the radiator fan is now running for a much longer period than before.I showed the problem to a local mechanic and asked him to check for leaks in the radiator.he didnt find any.but what he bought to my notice was that when the engine gets hot coolant comes spewing out of the coolant reservior.he says that some valve is not working and that he will have to open the head of the engine to check it out.

Now, i trust this guy as i have been going to him with all my vehicles (which were marutis).But what i doubt is his skills with fords because he said that he would call a specialist to check out the head..He said the total damage should be in the range of around 5-10K...

What should i do....

I stay in malad,mumbai...Any other good mechanics around here for a second opinion and also who could run a proper diagnostics check on the vehicle.

Also ive been used to driving a zen...but in the ford i find that when i revv the engine and leave the accelerator it stays at that rpm for a couple of seconds before it reduces rpm normally.the zen was much more responsive than this.is this normal or is something wrong...

Thanks in advance for your inputs..

I would really get it checked by a Ford service center if I was you.
If it is a problem with the engine (head gasket) then you need to get it attended to right away. Also, considering this car is just four years old, there's no reason (other than poor maintenance, extremely hard driving) why you would have problems with the head gasket.

Did you send the vehicle to Ford for a checkup before you bought it? If not, please do so now. Other than the coolant loss issue, ask them to give the car a thorough going-over, but to check with you before making any repairs / changing parts. They will call you on your cell and explain the work to you along with estimates before actually doing the work.

You can mix two brands of coolant, as long as they are both the same type.
There are two basic types of coolant, the old ones (usually blue or green), with inorganic rust inhibitors and the new ones (pink or orange) with OAT (stands for Organic Acid Technology, or Extended Life Coolant)


The normal conventional antifreezes use inorganic additives to achieve corrosion protection.

Extended Life antifreezes attain corrosion protection by the incorporation of organic acid salts.

The major performance difference between extended life and conventional antifreeze is the life-span of the product. Conventional antifreeze lasts only two or three years due to depletion of the antifreeze corrosion inhibitors. Because the corrosion inhibitors are different, automobile extended life antifreezes last five years or 150,000 miles.

Because the chemistry is different in conventional coolant and ELC, it is not advisable to mix the two products.

Check the coolant reservior cap. It should fit tight. Try to open the cap with one finger and if you can open it easily then you need to replace the cap or coolant reservior depending upon who is culprit.

Most probably, this will solve your problem else visit ford service center.
