Siena:

If you know nothing about automobile, ask questions, and be educated. Engine oil freezing? Even the least educated or technical individual knows engine oil can't freeze.

Overheating is caused by other factors, not a thermostat. Removing a thermostat because the engine overheats only masks an inherent issue. Nevada, Saudi Arabia, Australia, Dubai etc are much hotter than Nigeria. Guess what? Their engines run thermostats. The thermostat does NOT control temperature from the surroundings, it controls the temperature from WITHIN.

Running without a thermostat will cause an increase in fuel consumption, as the ECU will think the engine's cold, and dump in loads of fuel. The only way the ECU can relate fuelling to coolant temperature is via the CTS (coolant temperature sensor). Excessive fuel going through an engine on a constant basis gives rise to "bore wash". This is a condition whereby the oil lubricating the cylinder bores is washed off by the copious amouts of fuel being introduced. This will then wear out the piston rings AND bores. This is when the engine begins to burn oil, with lots of blue smoke from the exhaust.

What is deemed as "overheating" in the Nigerian context?

An engine running between 75 - 100 degrees Celsius is NOT overheating! That is the optimum operating temperange! So if your gauge indicates midway or three quarters, that is perfectly normal!

If the bores wear out, there's no cheaper option other than a replacement engine. An engine is designed to burn a certain amount of fuel at a specific engine speed and load. If too much is injected, the engine can't cope. It will struggle at low speeds, sometimes misfire as the amount of fuel it's being forced to injest floods it, and spark plugs will usually be soaked, and black. This is also one of the reasons the oil level in these engines is often above the maximum mark - it gets diluted with gasoline, which thins it out. gasoline-diluted oil is as useful as running cooking oil in your engine - zero protection, and will later result in worn big-end and crankshaft main bearings, giving rise to "engine knock".

An over-cooled engine also means the oil will also run cooler. Oil below 75 degrees is useless, and will attract condensation (water droplets). This will turn to sludge over time, and is one of the main causes of oil pump failure. A failed oil pump will starve the engine of oil, leading to complete seizure.

Thermostats are fitted by design and function, not to make your engine look pretty. It IS an integral part of the cooling system, and should NOT be removed under ANY circumstance. If your "mechanic" insists you remove your thermostat, then I'm afraid it's time to find a real technician / engineer to carry out repairs and routine maintenance on your automobile.

Why do you guys think automobile that have been running perfectly well whilst being used abroad, suddenly suffer catastrophic engine failure once they land in Nigeria? Bad mechanics, who don't know one end of a spanner from the other, and who shouldn't even be allowed to swing a wrench near a wheelbarrow.

Good luck!

nony30: People make mistakes due τ̲̅ȍ misinformation.I have had issues of overheating in the past with tokumbo cars and once the thermostat is removed Į̸̸̨ƭ stops right away,so Į̸̸̨ƭ was only natural τ̲̅ȍ profer the same remedy which worked for me τ̲̅ȍ a troubled nairalander.well op I am sorry and didn't mean any harm.thank God the havard and igwebuike educated true mechanics in the house siena and ikenna have come τ̲̅ȍ Ɣ☺ΰя rescue.@ least I meant •̸№ harm just trying τ̲̅ȍ help out.
