Why Does A Car Overheat? by franugo(m): 1:44pm On Feb 18, 2018
my dad's car is prone to overheating. the level of overheating is mind boggling, you'd fill d tank with water and after driving a little distance, d water would start boiling n would have to be changed. and on n on it goes. the car has been worked on severally but either the mechanics are incompetent or d car is incurable. Please, I need opinions on what could be done to stop the incessant stops n refilling

Vehicle should contain coolant, not water.
As you said the vehicle has been worked on several times, very likely the system has been terribly compromised and every trick in the book tried which will mean a total overall will be necessary to return to factory spec.
What's the vehicle make, model and year?

Might be wise to buy another better replacement engine.......

Head gasket is too tired and wants to retire completely.... While your Kazeem is at it, check conditions of radiator + thermostat....

dirty radiator, bad cooking fan, weak water hose,
bad gasket, bad radiator cover ,check for cracks on all plastic and rubber, bad seal.

The radiator is likely Too small.

You bought a car conditioned for winter to high temperatures. Get a bigger radiator.

Once you're sure fans are functional and you add coolant to the water you use and your gasket is not burnt.

Alot of factors can cause engine overheating
, from lack of engine coolant to a faulty engine fan, to a faulty thermostat to a bad hose, to a bad water pump, to a bad head gasket, to a bad engine
All are culprits..

Check the kinda engine coolant your dad's car uses. Not every car use only water as a source of coolant, you can mix up anti freeze to raise the boiling point of the coolant

If that doesn't work check if your vehicle fan is blowing well and the direction it's blowing air, also the electrical wiring fuses and relays An electrician can do that for you. You can also step up the fan to see if it would help.

If that doesn't work check your cars thermostat, although most cars are equipped with thermostat, sometimes due to weather difference between us and temperate regions it can cause the engine fan to malfunction

If that doesn't work check wether there is a leaking hose, especially from the radiator side to the engine also check if your radiator is dirty as well otherwise you have to wash it or replace it

If that doesn't work check the water pump, a faulty water pump can cause an engine to overheat

If that doesn't work check the head gasket, a bad head gasket would leave an oil trace on the radiator coolant, if you check your coolant every morning you would see oil traces

If all of the above doesn't work it means your dad's engine is bad, or weak or very old. At this point consider getting a new engine or a vehicle. Overheating destroys the engine faster than anything else

This could be a simple case of bad radiator cover or in worst case the entire radiator.

The problem is no Mechanic drives the car, so the mechanic is not there when the problem happened and will most likely treat one issue for another. It is your responsibility as the driver to do some basic test and observations which will aid the mechanic in choosing the actual fault. A leak, is not the same as burnt head gasket. A bad radiator cap is not the same as bad radiator.

I suggest start from the cheapest solution. That will be to change the radiator cap. Cap failure causes boiling and spilling of water in a system that seems ok. The reserve tank will always fill up then spill water from there.

Re: Why Does A Car Overheat? by Hunter22: 8:22am On Feb 21, 2018
Lot of things can attribute to that.1) most of the cars come with thermostat because of the cold weather abroad so it would still keep the engine hot till the next day, once it not been removed here in nigeria the car overheats on every little stress like when put on the Ac, on a hill, trafic etc. 2) when your radiator And Ac vent is not alway washed to allow the free flow of fresh air. 3) when the engine top gasket is somehow burnt it makes the engine over hear,4) overloading does that.5)low or no water.6)radiator fans re one of the slow poisions, when the rotation decreases like it doesn't bring in air from outside into the engine( you can check that buy using an empty sachet of pure water and placing it right infront of you car Ac external condenser while your engine is on, if it sticks there know it's okay and if it's not, has an issue.. Thanks ya all, hope it you get the solution here

An American car, for example, is built to withstand below zero to mild weather.

Nigeria is hot all year round and the temperature being high helps increase the possibility of over heating.

Is that clear enough?

Yes, People pass out and even die here from too much heat/dehydration in Arizona for example. And yes when temperatures are high it overheats cars.

OP. Check the radiator hose and see if any is leaking, weak top gasket, please use coolant instead of water. And most importantly, loose the vehicle radiator and take it for a wash, (machine wash), maybe the radiator holes are blocked. Thank me later

cars a designed with a range of expected ambient temperatures. cars do not require any modifications to be used in a particular area,
except for possibly winter tyres and anti-freeze.

Finally you do not require insults to pass a message.

Which basic facts? A 2001 MB C class with thermostat, on AC and full load doesn't overheat. Your point is wrong sir. Verify on google.
