Temperature meter

[Mllcg]

In my opinion, apart from the fact that Aircon system shares part of radiator system with engine cooling system, there is no relation between these two and all the cooling takes place inside the cabin. I am not sure if switching on AC really helps!

 

for my car, when my aircon is off, my oil temp spikes.

 

once i turn it on, its a more comfortable oil temp. party to do with the fact that turning the aircon on starts the fan spinning.

Sorry sorry perhaps I am not clear.

 

I used to top up using water only. Went SK do my repairs to wear and tear parts, and switched to coolant. Noticed that the meter now registers a slightly higher temperature compared to using water. I was thinking something was wrong like leakage.

 

Confirm no leakage (yet). Attached photo of meter using coolant.

 

 

Previously when using water, temperature was about 2 to 3mm lower. Just wanna ask if its normal. In both cases, meter is stable, and have never hit the halfway mark.

 

Apologies if I caused confusion.

 

Does registering a higher temperature equates to a lower engine performance (could be due to hot weather too), I seem to be feeling it. Paiseh, I think for old school manuals, every little differences can be felt.

If you can, borrow a OBD reader so that you can see what are the temp readings from your ECU and confirm whether the readings are normal.

 

Normally, my needle for all my cars are always at the middle. Even when my temp spike up by 7 degrees when one of the fans broke down, it still stays in the middle ( I know because I have a OBD reader on board).

 

For the Honda that I'm driving, typically my temp range is between 86-90, and for the Toyota that I drove previously, the range was between 95-98.

 

One thing I noticed for my current car is that one of the fans does not kick in until a temp of 92-93 is reached, and so sometimes the temp can go up to 98-99 before the effect takes place.

 

Hi

 

during these hots days, after driving a while the needle tend to stay where har?

 

My meter needle will be about 3/4 to 4/5 to the half way mark (never hot or cross the half mark though). is it ok?

 

will change of coolant affect the reading? i recently change from using normal water to using coolant.

 

thanks in advance for any comments or advice.

 

thank you.

There is a trick to using this method.

 

One workshop manager from a premium conti car brand taught me.

 

Turning Aircon to use A/C fan to help cool radiator.

 

BUT temperature must be set higher in such as way that the frequency of A/C cut in and out will be rapid.

 

No doubt that setting A/C thermostat low will allow A/C fan to continue blowing, but it will also load engine, which contribute to further increase in coolant temp.

There is no numerical temp scale on your meter.

 

If this is the usual stable operating temp, it looks normal to me for Asian cars.

 

Conti car usually operate at 82-88deg C temp range.

 

So I think you can relax on this.

 

On your question of higher temp will loose engine performance, I think you already experience power lost before, so it is double confirmed.

Higher temperature means thinner oil viscousity, and that leads to drop in oil pressure.

 

If you user of NSHW, you will experience this with a short coffee or toilet break, to let engine cool down.

How do you know the operating temp range? Is there a numerial temp scale in the cars?

Should one be using water with additive, or wholly coolant or something else?

 

 

[5936]

Usually not in modern cars with analog dial gauge, those with digital gauge will have the advantage.

I remember in very old car or diesels

 

 

My deduction will be that, if normal operating range is 0-100, then 50 deg will be middle.

 

Over range is red= boiling

 

To have a scale with no scale is already thousand times better than my car without a temperature gauge.

[Jchuacl]

I prefer those pre-mixed coolant so that I don't need to add water.

[Jchuacl]

No. Even when my water temp reaches 107, the needle still stays in the middle.

 

That's why I like to have an on-board readouts for the ECU parameters that are of concern to me .

It that coolant or EO temp?

 

107 is really a serious "emergency".

[Satria_neo]

Are you sure? If thats the case you might want to check out your water temp sensor. Cause I do know some cars uses 2 temp sensors. One for the gauge and another for the ECU.

[Jchuacl]

I said water temp, isn't it clear?

I'm sure.

pls check it out. 107 for oil or water temp is bad

[Jchuacl]

That was when one of my fans broke down. If I were to depend on the temp gauge, I won't know as it stayed in the middle. My obd gauge was giving me the warning signal and that alerted me to the fan problem.

dont follow the car "temp" gauge. its not even accurate.

 

mine is always half.

[Jchuacl]

That was why I advised the TS to use OBD scanner to confirm the temp.
