3. Water is not an effective coolant

Take what I will tell you very serious so that mechanic don't finish your money.

I am telling you from experience
Every volkswagen radiator in control by the airflow circuit system, so every time you open your radiator in the morning or afternoon before going out you depressurize it whereby creating air bubbles when your radiator heats up that bubble increases your temperature because is now gas in water.

Don't open your radiator every morning , monitor your water level from the radiator plastic container.

If you must put water in the radiator do it by 4am when the engine is cold.
Don't ever open your radiator during the day to put water.

Do this and monitor the car for two days.

The major problem you have is opening the radiator every day and topping water above the recommended level. Allow space to allow the gas bubble generated by heat from the water to have some space.

Thank me later

Most mechanics are just dumb assholes, they will be changing one thing after another until they completely kill your Engine. Had the same problem with my car and they continued extorting me until I had to buy a new engine and that solved my problem permanently. If the cooling fan is working and water pump is working without leakage then the radiator is probably dirty or bad you may either wash it or buying a new one will be better. But know that radiator issue is usually accompanied by irregular movement of your temperature metre. The temperature gauge always goes up and down.
You said you usually top water everyday, then look for leakages especially at the radiator and water pump side

@7 pages, a lot can contribute to why your car overheats. Changing speedometer sensor and the fuel pump does not have any correlation with you car overheating.
1. Check that your radiator is not clogged with mud if u usually pass through muddy pool of water on the streets. If clogged, ensure u take out the front bumper to have access in taking out the radiator for a wash/flush. This will enable the radiator to breath.
2. If your car is using a single fan, check that the connection is intact and not having partial contact or not contacting in supplying adequate power to the fan. If it is supplying adequate power, then ensure the radiator is flushed but if it's not supplying adequate power, check the relay under that water tank. It could be that the relay is faulty and needs to be changed. The relay controls the fan module for radiator and air conditioning fan if yours uses AC if it's a double fan. Taking the thermostat to original setting has nothing to do with you car over heating because I know the one that came with the car has been removed to allow free flow of water circulating the engine. For the top gasket, ensure its changed. Also check if the water pump is faulty as this could lead to your car overheating.

It once happen to me..se its two things..your radiator is dirty..itis blocked with dust and sand.u will take it to mechanic..they will remove the radiator.n take it to car wash..the car wash will use that spraying gun to blow the inside with hard pressure spray of water..u will see sands n dirts there after fix it back.let d mechanic fix it back n u will pray for me..second..if u change ur fan.i mean if the fan stop working .then expect over heating..but if the fan is working..go n wash your radiator with that spraying gun pressure.

your advise is noted bro.

the fan was running when it overheated in the morning and I've to remove the pipe that run with the radiator and allow it to cool down before topping it water only to experience the same in the evening while the fan stop running


most of the times the fan run and it still do overheating, I've to follow your advise by washing the radiator


thanks for the advise

buy a portable air condition and install it in the bonnet. that's all

Tango123:


How is he to keep the engine clean? Is he the state and federal government that are to maintain roads


Or do u want him to be washing his engine daily or what. Anytime u wash engine, u run risk of water going into the wrong place, and ur car will develop massive fault

Engines are not built to be washed

ignore Sholaco and other babies ignorance. I don't exchange words with babies that wait for their parents to eat

Change the water pump since it is a vw. Most vw parts fail after 60,000 miles or 40k miles. That is if it has not burned the gasket

ZIMDRILL:


the chances that your head gasket is gone is very high, you need a mechanic who is good at investigating a blown head gasket and also check for leaks within the cooling system

yes the mechanic I used confirmed the gasket is gone yesterday because I've to manage it to the workshop


I will change the gasket and check for leak as you said bro. thanks for your input

A lot of fake fuel.pumps out there, use radiotor coolant instead of water it goes a lo g way bro

The problem with seeking advice online from a general , non- specialist forum is that you get confused because everyone will want to say something.

First off, do not mind those advising you to connect your fans directly to the ignition. Your fans are supposed to work on/off depending on the engine temperature.

Secondly, whether your thermostat is stuck open or closed, i do not think it has anything to do with the overheating. In cold weather, you won't get warm air in the car if your thermostat malfunctions.

I suggest you reverse any new wiring introduced by the "rewire." Most importantly, check your water pump and radiator. Perhaps they are not working fine or clogged. I have a guy who replaced top cylinder gasket 3 times due to overheating. What solved the problem was a new radiator.

Please come back here with feedback so we know what solved the problem.
Good luck.

Kenbuzzy:
Bro, sorry for ur troubles. First, start by cleaning ur engine. Dirt on the engine and the radiator causes overheating. Bring out the radiator and do a proper steam cleaning of the radiator. Get a 65 degrees or less thermostat. Once the temperature raises to 65 degrees, the thermostat opens and the water pump sends water from the radiator to cool ur engine down. Check ur water pump and if possible replace it. Also confirm that ur radiator fan is working effectively. Do all this and I don't see a reason why ur car engine should be overheating.

thanks for your input bro

You see a guy trying to make ends meet legit and here some idiot instead of giving him good advice or keep quiet if there is none they are making mockery of him .@ops try get a specialist on Volkswagen cars to check you water pump, gasket,and the radiator might be dirty or air is trapped in it and might need rebleeding .

Kibonko:
the radiator is definitely smaller than the engine....get a bigger radiator

your observation is well noted bro


thanks

Noted.. Sell it With immediate effect! Sorry for the inconvenience. Stay blessed.

I still remember as my golf 3 give me overheating wahala.

So many faults were suspected, from dirty radiator to failing water pump to leaking pipes...

Finally na when my mechanic come sit down check am well well , naim im con see say e get where the engine dey leak water.

So im con tell me say the gasket don crack.

Na so we go change the gasket o.

Na so the overheat come take disappear o.

Thank you Jesus.

Let your mechanic remove the thermostat.

7pages:
I hope to get answers and advise from you guys please

Your First step is to remove the radiator, take it to the guys that work radiators to wash the inside. Then take it to a car wash stand and blow it back and front.

Watch as your car becomes practically perfect.

If it doesn't work find a better Tech Guy to look into it, sibce nothing happens to the gasket, u have to use double cells. As engines weakens out, radiator tend to reduce in capacity to cater for the higher temperature of the engine thus need' for double cell. But strictly on the tech guy's advice.

But do what I first wrote and thank me later.

I had such terrible experience with my Benz that nearly consumed me financially. After mechanic has exhausted his ability, I got the solution by changing the radiator cover for just ₦500 after wasting ₦000s of my hard earned money .

Thermostat and radiator. That's all. Do not wire the fan direct. It should be working through the relay

Bullet01:


OP pls go with this advice and you will be fine. Pls remove thermostat too if you have any in there.

well noted bro

unclemaths:
The number 1 problem of overheating engines is Leakey radiators.
The second is fan.

When the radiator leaks, the engine overheats and you have to be topping the water frequently.

It is not the overheating that makes the radiator take extra water. Rather, it is the leakage in the radiator that led to other things.

Try to flush your radiator and check its connecting pipes.

this clear enough. thanks Boss

Good afternoon, were do you stay.

I stay at Ikorodu, Lagos bro

Check the fan direction or air flow.

Check and flush your radiator If it's clogged happened to me once. I was using water as coolant and left it in for too long. Its a big radiator had to be taken apart and put together

Your car definitely doesn't have a thermostat. So get one.

Check you oil fill cap if it's milky then your head gasket must be damaged

1of these 4 things can be responsible .

Check ur radiator cover if it’s bad , change .
Check ur fan whether it’s rotating
Add coolant to ur radiator
Remove ur car thermostat
Check whether ur radiator body is dirty and block, it can prevent air from going into the engine.

Good luck

Thermostat is the answer

1. Try bigger radiator
2. Then buy brand new gaskets(wait there to see them put in the new gaskets, they sometimes play games and put used ones if you're not there)
3. Try avoiding traffic
