So I would take it as water coming out from the exhaust tip is normal?? If I do remember correctly, my 3 years Saga FL also showing sign of water coming out from exhaust tip, but that is during cold day when I am leaving for work.

If this method works, I dont mind trying out
For the sake of my curiosity, when you are saying "burs-up", how bad would it be?? LIke open a carbonated can after well-shaked?

I wish it is a GOD car Perhaps it is just a God-car-alike in disguise

Yeah I am planning to do so. Thanks.

Yes it is normal. Water is a byproduct of the combustion process in the engine.

It depends on how bad the gasket leak. If it is a small leak, the water may just overspill. if a big leak, maybe. As far as I been seen, not as violent as shaked carbonate can. But...theoretically, it can be.

That's why I said it's to be done when the engine is cold. Once you see the water burst, shutdown the engine.

You mechanic looks like inexperienced fella. With 1K, i would have spent it on radiator service (take out/ flush/ leak test/ welding if leak), simple radiator hose check, dissasemble hose, plug 1 end of hose, pump some air inside and put in water bucket check for leaks. Test hose for brittle mesh by pressing it. Good ones rebound. Hardend ones have cracking noise.

Coolant should have left colored traces at gaskets and water jackets if there are leaks.

If all those cannot work, assume the worse is you have warped block or head caused by overheating and rapid cooling. Can either skim to make them flat again and replace gaskets.

I'm, not mechanic. But like to hang out at my mechanics place and see how he solves problems and share it here once in a while.

Youtube have a lot of DIY check for leaks and overheating problems.

Any will do since this is to help find the problem. .. But since it's a Toyota.. use Toyota long life coolant

Note : later after problem solved you probably need to drain and refill water plus coolant.. so any brand coolant will do to find the leak..

Hopefully not leaking into engine.. u might want to check engine oil see got oil + water mix also.

Water pump got change ???

Water pump got change ???

Goto a radiator specialist. They know radiator best. Normal Mechanics are like general practitioner. They would send ur radiator to them for cleaning and charge u easily 50 bucks more. 1k for hoses and rubber change is a rip off. I got my radiator flushed and cleaned, changed rubber hose + new radiator cap and coolant for under 500 bucks.

If you are really sure that when you checked the temp and it appears normal yet hot air blown out from aircond means that your radiator fan has failed. The radiator fan is also the a/c condensor fan if not mistaken. When that fan fails you will lose aircond cooling and engine cooling together. Correct me if im wrong.
Intermitten failure of cooling fan can cause random and hard to trace overheating. Other things related to fan are fan motor, temp sensor, ecu fan signal (if fan operates by ecu trigger), fan relay, fuse, wiring n contact points

Loss of coolant...
You mention radiator tank, not radiator itself. If you're talkin about the 2ndary coolant tank near the radiator loosing coolant after overheating, its normal...it was circulated into radiator and engine to accelerate heat transfer.

If you were refering to the radiator water level itself, i dont think you can see thru the bottom to know it is 'empty'. there may be alot of water below the level you can see with naked eye. Did you try to top up? How much did you need to top up? If it was really empty you will need 5L plus or so of water.

From experience it can be a few things, simplest things will be worn out radiator cap, hoses, drain plug, thermostat and it's housing area. If the fan failed and these parts are worn out, they may leak water.
More serious things, somewhere cracked on the metal parts of your radiator or engine which only opens enough to leak water when hot enough. Internal engine failure/damage like what others mention above.
It can also be leaking thru your water pump area which is usually covered, driven by timing belt/chain.

Others in thread hav mentioned almost all causes, best to find a better mech as this is basic stuffs. Btw, your mech any chance in damansara area? His style simillar to one mech i know many years ago, lost 10k+ to him the hard way.

If it's already filled with water, you can drain the radiator abit with the drain plug at the bottom of the radiator.

Changing the head gasket would be equivalent to a top overhaul as it involves removing the head. But if its really the head gasket, your mech is really, really bad that he couldn't identify the problem. Another thing is from hearing his explanation on 'piston block had worn off causing high heat' and 'water leak through the engine and coming out through the exhaust' is complete and utter bullshit and shows his level of technical knowledge, which is close to zero. Water leaking from water jackets to the cylinder will cause white smoke, not water out the exhaust. Water out the exhaust is common during cold morning due to condensation.

If referring to the method of checking for blown head gasket by looking for bubbles with the engine running and radiator cap open, it should be bubbling quite alot. If there's no problem with the head gasket then there should be no/minimal bubbles. And as suggested by some, a pressure test can and should be done as well. The fact that your mechanic didn't do it also shows his lack of experience. Doing a full overhaul or changing engine just because of a water leak is like reformatting a PC just because of virus or spyware.

I work part time at a workshop by the way with a boss who have 30 years experience in this field. I'm just a kuli

Thanks a bunch for all the suggestion provided guys.

I just did a simple check yesterday which are below :
1. Coolant is inside the radiator instead of water
2. Radiator cap looks old but not sure got still in good condition or not, I cant see any cracked on the rubber but I think I will get it change.
2. Removed radiator cap + start engine : coolant level go down and no visible of much bubble but I think got minimal bubble (or it is engine vibration that cause it ><). No bursting happened.
3. I don't see any leakage when I check at the bottom of my car. Just bend down and look.

I think I will send my car for Radiator leakage checking/wash/service during the weekend

Well sometimes cannot fully blame the mechanic. Some mechs will do full cooling system service eg.radiator service, fan motor, thermostat, hose and links, radiator cap replacement, temp sensor, water pump and top overhaul together. Some may even say engine overhaul only but charge u extremely high and do the full service quietly, as the other parts are relatively much cheaper should he use oem or non original parts.

Why? Cuz it completely solves the problem and should last half a decade at least if job done properly. Saves time and prevents customers from fucuking them upside down if cannot solve the problem/ taking too long, plus its a long lasting solution. Altho if you did specify u're on a budget or to troubleshoot root cause the correct thing to do is start from engine external, if failed then only engine internal. With proper troubleshooting and inspection methods of course.

Thats my only argument for the mechanic to be 'fair'.lol. but he still shouldnt jus jump to top overhaul and all that nonsense. Good luck!

Partly to be blamed is me myself too as that time he called me during checking and inform me about the rubber hose leakage, he told me that there are 2 leakage and advise me to change. At that time I didn't specify to him only change that 2 hose but upon talking with the mechanic I was advise to change the rest of the rubber host as well, so I inform the mechanic to carry on with the changes but only to find out at the end is that the total rubber host he changed is 12 pcs and cost up to 1k

Oh well, lesson learn..next time I would need to specify and ask for more details before letting mechanic to "cut-throat" me.

Once again thank you guys for all the precious information that been provided to me. Hopefully I am able to solve this over heating problem soon.

Good Day to everyone in lowyat forum.

My father's Avanza has new problem again This time is jerking. While changing gear and while cruising I can feel the car jerk from time to time. At first it is intermittent but this few day the jerking happened quite often.

Send to workshop and change spark plug and the wire coil but problem still persist. The mechanic suspect it could be due to the Clutch plate. Anyone can advice me is there anything to do car jerking whiale crusing with clutch plate?

Thank you in advance for your valuable feedback.

Any feedback?

Throttle body dirty or sensor faulty will cause the car jerking too.

Jerk during gear change emit noise?

Could be clutch plate symtoms but honestly, the mileage seems a bit low for clutch plate to give way. Normally, clutch plate starts to give was for say a 10-year old car and mileage > 150,000 km. At least, that's what happened to both my Manual Cars.

You can try to change the Transmission Fluid first.

Unfortunately, the price estimate is not available but my guess is not more than RM600

Btw, your radiator problem fixed already. Wanted to share that my wife old car also had similar issue, the top part of the radiator had hairline cracks and water was evaporating. The mech tried to check for leaks int he pipping buy could not find any leaks. Waited until the engine was hot and could see that water was evoporating on the top part of the radiator

If u want a good air cond / radiator, check out this is a famous air-cond / radiator repair shop at Jln Raja Laut, right behind the Honda showroom called Ming Wah. Quite famous with reasonable charges.

Its Jalan Raja Laut heading from Jalan Ipoh / Chow Kit towards KL. After the Pizza Hut, you cant' miss it. If you are Chinese (or can ask your Chinese friends), the very famous "Pan Mee' shop is just around the corner.

Sorry for asking, what is throttle body bro? The sensor you referring to izzit O2 sensor? How to check the sensor is faulty or not?
Thank you and appreciate your feedback.

no noise bro, just jerking during gear changing and also while cruising.
Thank you and appreciate your feedback.
