I think the anti-freez also raises the boiling temperature of water.

I doubt that i might be wrong though. What i know is The anti freeze in the coolant is basically to prevent the coolant from freezing at lower temperatures.

haslaw:
After the gasket was changed, oil was found in the coolant while water was found on the engine oil dipstick Also, there were signs of water in the engine combustion chamber.

The radiator cap and hoses looked OK without any signs of leak.

You obviously have an internal leak

chibjohn:
Water boils at 100 degrees Celsius at atmospheric pressure. If you increase the pressure, the boiling point increases. A car cooling system is pressurised. There is no way it can boil at 100 degrees in that pressurised state. It only boils when the pressure is relieved like when you open the radiator cover of a hot engine.
You can use water as a coolant in tropical Africa but only distilled or demineralised water. I use demineralised water in my car. We don't get to sub zero temperatures here. So, we don't need antifreeze that is added in coolants. The antifreeze simply stops the coolant from freezing at very cold temperatures thereby preserving the integrity of the cooling system at cold temperatures.
You are discouraged from using ordinary water because it contains minerals like calcium, magnesium etc that precipitate out at high temperatures and end up fouling, depositing and blocking pathways for water passage. The effect is the reduction in heat dissipation effect of the cooling system resulting in overheating and engine damage.

So if you are living in Nigeria and can lay your hands on Distilled water or demineralised water, use it as your coolant. Nothing will happen to your car because of that and your cooling system will work well as if you are using coolant.
But, if you can't lay your hands on either of the two, you must use a coolant. Never pour in ordinary potable water into your car cooling system.

� you are so on point... However let me add the additives in coolant also help lubricate the water pump and this is very important to help the pump last long...

Have an issue with my tranny - Passat B6 2008 FSI. Tranny shifts out of park, doesn't engage and gets stuck at neutral. But if shift cable is drawn at engine side, transmission engages and drives fine. What should I do?

Find a competent Transmission pro to help you fix this problem. You cant do this yourself.

Loud it sir!!!!

DJ abeg increase the volume...

Radu, If you go through my comments again as a rebuttal to the person i quoted, i only stated the the ability and possibility to use water in coolant systems without suffering the debilitating effects of engine overheating. And i also tried to clarify the nonsense that premixed Coolant has to be used because an engine is running at a temperature of 1500 deg.C ( This temperature is within the combustion chamber and remember the water flows round the external sides of the combustion cylinder like a cooling jacket and has no direct contact with the combustion chamber, and because the cooling system is pressurized, the boiling point of water is greatly reduced{think of the operating principles of a pressure cooker}, of course with the help of applying thermodynamic principles such as coolant flow-rate, forced convection etc.). Water can serve as a coolant but should only be used in a short term e.g when checking for/ repairing leaks.

The invaluable benefits of using premixed coolants( as per manufacturer's spec ) cannot be overemphasized.

I will take distilled water over all this plenty adulterated coolants everywhere. Many of them are just colored water... No anti-freeze whatever there

Inception:
No sir.
The stripped bolts issue was a manufacturing defect that affected some early production 1AZ and 2AZ engines. It has nothing to do with the kind of coolant used

Secondly , water can be used in a vehicle cooling system , but it has to be distilled water and the climate must not be temperate. This is because the cooling system is pressurized. So the engine operating temperature and water correlation does not hold water (pun intended) . there are a lot of design considerations and parameters involved ( coolant flow rate , thermal conductivity of engine block/ cylinder head, rate of heat dissipation due to forced convection etc)

The coolant we use( recommended by the vehicle manufacturer BTW) is simply chemicals and compounds added to distilled water that helps in improving the specific heat capacity and permit a much wider range of operating temperatures ( winter starting to prevent the coolant from freezing and expanding in the engine block that can cause catastrophic damage, for example. )

Gbam!!! U deserve a nobel slap award sir...

thebigkendo:
Bolded is not entirely correct sir..

Water in engine cooling system won't even boil at 100degC...

So many other things can cause overheating

Exactly... Considering the radiator cap raises the pressure of the water, the water in a properly functioning cooling system will never boil as is boiling point would have been raised due to the pressure build up.
OP kindly start with the simplest things
1. Find a tech that knows his stuff.
2. Pressurize the system. Check for leaks or a drop in pressure.
3. Inspect radiator cap.
4. Inspect hoses while vehicle idles at operating temperature.
5. Check your gear oil and engine oil to be sure water is not leaking into the engine ir transmission.


Atleast start with these first

haslaw:
WE had the mechanics look at the threads and they were OK. The gasket was changed again and the issues still persisted.

Any other ideas will be greatly appreciated

before going through all this stress did you atleast perform a cooling system pressure test?

haslaw:
Good evening

I opened the hood of my corolla 2010 car today and found out that the radiator coolant in the reservoir is empty. What brand of coolant should I use and do I just top up the coolant of do I need to totally flush and replace it.


cc: AutoMoTech Autologic carmartng GAZZUZZ

before refill pls confirm you dont have a leak in your cooling system. i am suspecting you probably have a leak. your coolant isn't supposed to just dry like that. do a pressure test and see...

UcLloyd:
I always give him my car to go work on. I don't understand this very one. Is it possible a gearbox will get bad without prior signs? No noise, no gear changing problems, no burning smell, no sign at all. This is the first time I'm having this gearbox issue, but I've seen people tell their tales na. If he really did anything fishy, is already done, I just want to know if is possible for a gearbox to go bad without first showing signs, I don't want to overeact unjustly. AutoMo Tech

I understand brother. its best you dont over-react.
however have you checked the transmission to confirm if truly its emptied? Papa Gaz said u should check CV joints.
kindly let us know whats up pls

radautoworks:
Bad influence

UcLloyd:
Somebody please tell me my kazeem is lying. I checked this gearbox oil on Saturday before I started the car to warm it and i parked it back, there was oil. Today when he came to go and change my spark plugs, My Car won't move when u put it on gear, both drive and reverse. There's no oil underneath my car either. He said my gearbox failed and I need a new one. I thought the gearbox will show signs before going bad. I'm so confused here. My car is Avalon 02.

Sorry to say but we can't tell you your mechanic is lying. You were not there, we were not there. All we have now is your own side of the story. It wld have been great if you were there. I perceive you trusted the mechanic to go work on your car. Bt now this unfortunate situation.
Regardless As it stands you need to find a solution.
1. Get another mechanic who is competent. Refill the gear with appropriate oil. You might be lucky the gear is still good. He probably just wanted to rip U off with a quick one, or he might be saying the truth. We dnt know.
2. Even if the trans failed, there should still be oil in it. Seeing there is no oil and no trace of any leakage, then there is something very fishy.
3. If you are sure there was oil, lock him up for a few days until he pays for that transmission. he needs to learn a lesson Many mechanics out there live in lying. They dont fix shit. However if u're not sure, you need to consider your options.

it's external for sure. Let me run back to my thread, I'm beginning to constitute a nuisance

Come back here... U gif U permission to go?

Lexusgs430:
Make i stand up..........

Baba U nefa knee dan U wa stand again? Knee dan my flend

Lexusgs430:
Oga, that small leak i go dey manage am....... I get water plenty........

I would advice U atleast just do a pressure test on your cooling system. Atleast find out if its an internal or external leak.

[quote author=GAZZUZZ post=84557912][/quote]Lwkmd

Lexusgs430:
Solved..... The coolant reservoir was low, i was only checking radiator......

Old age is a bad tin.....

Thank you all...........

Your ECU wasn't lying... U suppose knee dan bros

Lexusgs430:
It's a 2009. Would replace sensor and see if warning vanishes...

Thank you......

Pls check the wiring, ensure its good before replacing sensor.

Lexusgs430:
But coolant is not low........ Radiator has not lost any fluids.........

Automotech
Radautoworks

Coolant sensor wiring could also cause it.

Rocice:
Its reading error p2112
Throttle actuator .......

Throttle actuator is basically the throttle body. However i will need d full list of codes so as to be able to be able to give more accurate diagnosis.

GAZZUZZ:
Coolant low

@lexusgs430 told ya

GAZZUZZ:
You activated the spoil button, kindly turn it off

Savage you are sir.... ��

Lexusgs430:
The diagram for the coolant is different.

So ẹ get problem wey our Google no sabi?

Maybe GAZZUZZ Google, go sabi am........

e be like our google don expire o.
Abi Kingreign google... That one must know am...

Lexusgs430:
Does anyone know what this error diagram is? And yes i have used my own Google, maybe yours might know......


I am thinking battery, but i might be wrong....... Possibly faulty positive terminal, but this is from my very limited knowledge.....

All of a sudden i swear e be like say my Google too don kaput o
Abeg if you find the answer share biko.. i came across it once. I know it's not battery sha.. my mind dey tell me say na coolant something something..

nice ride

but

this ride is not 08.....not with this steering wheel

not with this gear shifter

happy sales bro

Definitely not with that dash.

row2ray:
First thing I’d advise you to look at is your plug and nozzles... do you have shooting sounds when revving the engine... then also check the vacuum hose routing and airflow..the valves is a last resort and changing it or grinding it would mean dropping your top cylinder.... was any work done on the car before that would involved them messing with the timing... they may have not tensioned the timing belt or chain and it skipped bending your valves

I appreciate the line of your thoughts. Faulty Plugs & injectors and also vacuum leaks can cause misfires and affect engine performance. However we need to be careful with thekind if direction we give so he wont waste money throwing parts at the vehicle. He need to diagnose this issue. Esp the cause of the white smoke. A jumped timing can also have such symptoms... So that is where scanning also comes into play

[quote author=MrDraey post=84522655][/quote]There is a possibility when the wheels were changed the technician damaged one of the speed sensors.
I can see your Check engine light on. That shoul give us a direction on what the ECU has seen and therefore turned off the Traction Control.
Be rest assred this is not a difficult issue. So dont stat throwing parts at the car.
Lets start with a scan. Post codes here and we go from there.
Pls use a capable scanner atleast one that can access the engine and ABS computers... happy Sunday

UcLloyd:
My car(Toyota Avalon 03)is having a hard start, and when it eventually starts, it will not fire well, and is bringing out too much white smokes. When I try to put it on Drive or Reverse, it will stop totally. I will start it again, fire it which will also not be smooth try putting it on drive or reverse, it will off. Please help. My mechanic says is Valve, I don't understand anything, help please

From the symptoms you have mentioned, white smoke is caused by either coolant leak into d combustion chamber or excess fuel being sprayed into.
Do you have any coolant leak issues?
Do you smell fuel from the exhaust?
Also kindly provide details of previous repairs carried out especially recently.
Also scan lets see what codes are stored in the ECU.
