Good morning house,

I have a challenge, my brother’s car (Toyota Camry 2007) has an engine problem and the mechanics have been unable to fix it. Water always disappears from the radiator without us knowing where the water goes. Two weeks ago, water droplets were noticed on the engine oil dipstick. The mechanics that looked at it claimed it was the head gasket and my brother paid for the gasket to be changed but unfortunately the problem became worse because not only was there still water on the engine oil dipstick, engine oil was also found to be floating in the radiator.

I decided to bring this issue to the gurus in the house for possible diagnosis and solution. Any suggestion(s) would be welcomed.

Thanks

The gasket is leaking sir ..

Find out why the headgasket got broken in the first instance cos headgasket will not got broken unless there is a hidden fault and it until fault is discovered and removed you can go ahead to perform a successful engine rebuild or else it still back to square one .
Also the extent of warpage to the cylinder due to the overheating need to be ascertained so that proper corrective action will need to be taken in course of engine rebuild work. .

GAZZUZZ:


confirm if the condition started with over heating.

Confirm if there is a history of head gasket change

Confirm if engine is V6 or 4cylinder

The condition didn't start with overheating.
The gasket has never been changed.
The engine is 4cylider.
Though the gasket that was removed was warped slightly.

Thanks.. That's what everyone is saying...

Google stripped bolt 2az-fe. Toyota

3 threads at the back of the block have stripped, replacing gaskets with original metal or graphite will not solve problem.

Engine needs to visit a machine shop for repair of the threads on the block.

Sir, this is the problem affecting your vehicle.

Follow the suggestion as stated by Gazzuzz and you will be fine.

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.

1. Whats water doing in your radiator?

Temperatures in your engine can reach 1500 degrees centigrade. What temperature does water boil at?

How can you then efficiently use a substance that boils at 100 degrees centigrade to cool and engine that runs at very high temperatures.

Using water was the root cause which then led to the stripped bolts. When you repair your engine, stick to the recommended coolant

I said exactly this to the young ladies the Society Of Women Engineers brought for a field day today. It was a simple concept for them to grasp

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

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. )

It is a manufacturing defect aggravated by inefficient cooling as a result of using the wrong coolant!!! Keep on using water; distilled or otherwise “eventuarry “ your engine will correct you! I hope you also know that water encourages rust and that the coolant actually also lubricates your water pump and prevents rust.

......

Just read that you correctly stated that anti corrosion properties but i also insist that water is a poor coolant!

radautoworks:


I'm not talking about the bolts. All I'm saying to you is that plain water cannot dissipate heat as efficiently as coolant can. I disagree with your statement above. Plain and simple water cannot do the job. I don't care what climate you are in, it can't.

We can go back and forth about this all day or if you're in Lagos you can simply bring the car to the shop and we'll tell you the problem after seeing it since your current mechanic can't.

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.
