How to clean cooling  system that is contaminated with engine oil or transmission oil

How to clean cooling system that is contaminated with engine oil or transmission oil

A very frustrating situation can arise where either the engine oil or automatic transmission fluid finds its way into the cooling system and mixes with the coolant solution.
This can happen through the following;

Leaking cylinder head gasket
Cracked cylinder head
Faulty engine oil cooler
Faulty transmission oil cooler
Human error (pouring engine oil into the coolant reservoir or expansion tank) 

Removing oil from the cooling system can be a very difficult task to accomplish and it is one that requires a lot of patience and perseverance. 
Luckily, commonly available dishwashers are very effective for getting rid of oil from the cooling system.
Before starting this cleaning process, ensure that the cause of the coolant and oil mixing is al..

Cooling system's Thermostat removal should be temporary, if necessary.

Cooling system's Thermostat removal should be temporary, if necessary.

Many people have asked whether it is good to remove the thermostat in their cars.
For fuel economy and engine longevity concerns, the best is the have the engine's Thermostat in place. This can make the rings still be in good shape after many miles.
Where proper maintenance of using coolant solution and replacing the coolant (causing severe rust and/or scale formation) and Thermostat periodically are not followed, as in the case of many users in Nigeria, REMOVE THE THERMOSTAT to protect the engine from catastrophic failure as a result of overheat. Thermostat removal should normally be a temporary measure till you can get the cooling system clean, get quality coolant and quality Thermostat. Thermostat removal can be done for the purpose of troubleshooting too and then returned back to..

How a poorly maintained cooling system can damage a car's transmission

How a poorly maintained cooling system can damage a car's transmission

There are some cars that have transmission heat exchangers attached to the bottom of the radiator. Mineral deposits as a result of prolonged use of water can go settle at the water passage side of the oil cooler and block it. You will then have only ATF circulating but not water and hence no heat exchange. This is the beginning of the end of such transmission.
As the transmission will be overheating especially during high ambient temperatures, sporty or high speed driving.
This is because there would no longer be heat transfer from the transmission fluid to the coolant.
The transmission overheats, oil gets burned, clutches wear out, solenoids overheat and gets damaged, electrical wires resistances increase and so on.
This can be prevented by ensuring that the cooling system mai..

Coolant versus water in a car's cooling system

Coolant versus water in a car's cooling system

Many vehicle users do not see the need to use coolant in their vehicles simply because they put in water and their vehicle runs fine simply because they are unaware of the long term negative effect that it will have on their vehicle's cooling system and the engine itself.
Now, let's see how coolant performs when used and how water performs when used in the cooling system.
• Ordinary water - let's say either tap, well or borehole water. These water contain minerals that cause corrosion to engine block, piping and radiator core. Those minerals also cause scale formation. For better understanding, check your old home electric kettle, you will notice a brown layer under, that is scale! When water that contains these salts evaporates, it leaves behind the salts that forms scale.&..
