Drive a car without the thermostat? Is it worth it?

You may have heard many views on whether it's an absurd idea to drive a car without the thermostat. Probably your mechanic has also advised you to remove your thermostat, telling you it's only relevant in the western world. But before you harken to his advice, don't forget the amazing feature and relevance of a thermostat to your car engine.Like keeping your engine cool so it doesn't overheats.

This article on Naijauto.com will tell what will happen if you drive a car without a thermostat.

Is it an absurd idea to drive a car without the thermostat? Find the answer now!

1. Consequences of driving your car without thermostat

1.1. The coolant

The thermostat is a valve that's sitting between the car engine and the radiator. Its major purpose is to maintain an optimal temperature on the engine. The coolant from the radiator flows through the engine to keep it cool. When the engine heats up, the thermostat will expand and allow the coolant to flow to the engine to keep it cool. It also prevents the coolant from flowing to the radiator till the engine heats up.(it maintains a proper temperature so the engine doesn't go cold).
Now, when you remove the thermostat, the engine stays cool since the radiator is now closer to the engine. The average temperature a car engine is expected to run in is 80-100 degree centigrade. If you drive your car without a thermostat, it will run at 50 degree centigrade. When the car drives at this temperature, moisture or humidity will form. And when it is condensed, it will mix with oil and turn into slush (watery ice).This slush blocks out lubrication. When the entire system is not lubricated, they will wear out. So, the car's performance will be affected when you drive without a thermostat.

1.2. Engine parts

When you start a cold engine, the parts will wear out only inside the time of five minutes. And, because the parts are now worn out and not separated from the oil, the life span of the engine will minimize quickly. The engine will go through the closed loop procedure if the engine has gone beyond a particular temperature. If there is no increase in temperature, the engine will clog and stop entirely. This is dependent on how old the car is, but when you drive without a thermostat, the car will consume more fuel. This is because the engine control module (ECM) assumed the engine is yet in a cold state and needs powering up.

Driving without thermostat is suicidal to the engine

1.3. Thermostat replacement 

A bad thermostat can damage the entire car. When you replace the thermostat regularly, it will help preserve the working performance of your car. Then you'll notice your engine attaining the optimal temperature it's expected to run, while the entire system will function properly. So, you see the reason you shouldn't remove your car's thermostat as it can damage your car and its parts.

2. How to solve the lack of heat in the engine

When there's no heat in the engine, do this. You’ll use a large cardboard and place it on the radiator (in front of it).And it should be between the grill and radiator. This technique prevents the radiator from cooling down the engine. It simply reduces the cold air flowing to the engine. But while you are on this technique, be checking out the temperature gauge so the engine doesn't end up overheating. If the engine overheats, stop the procedure and take off the cardboard.

This technique is for when your car doesn't have a thermostat.

With these, you’ve now known that driving a car without a thermostat isn't a good idea.
