RE: Thermostats in cars: optional or compulsory?

in #stemng7 years ago (edited)

I salute the quality of your delivery sir. Who would have thought you have no degree in engineering. It confirms the level of smartness and intelligence.

The thermostat is one important part of the Automobile Cooling system. Like you have also noted, it is vital to fuel economy. The vehicles of today use a lot of closed loop control systems. If the engine is not heating up to the optimum temperature, the ECU will command more fuel to be burnt in other to satisfy the preset condition.

But my opinion is that you could have gotten the car scanned. There are preset diagnostic trouble codes to narrow down your troubleshooting. Although it appeared that the problem is solved with the removal of the thermostat. But I'm not convinced that it is the issue(I'm not contesting anything here though, just an opinion). Removing the thermostat is like supplying more coolant and it could possibly offset anything resulting in the overheating which may not actually be the thermostat itself.

You could have the thermostat tested. Perhaps it was stuck on the close position restricting the flow of hot coolant out of the engine. I recommend a hot water test for your old thermostat if you still have it.

It's simply done by submerging the thermostat in a bowl of water and then heating to around 80 - 100 degrees, if the thermostat opens then it is fine. Otherwise it is stuck closed and bad.

What I'm simply saying is that, I just feel you should be sure you have not eliminated the symptoms instead of the root cause.

In any case, I will just encourage you to get a thermostat back into the engine as so as possible.

hmmm. Thanks for the honest analysis. I really hope the mechanic will not claim that he's thrown away the removed thermostat. I will go there right after leaving work today. In case he claims such, I wont have option than to get another one. Do you have an idea of where and how much I can get it?

I will have the thermostat fixed back and then have the car scanned in order to have an idea of what is actually wrong with the system.

Thanks a bunch once again.

Well, most spares are gotten from Ladipo market in Oshodi, but it looks like you're in Osun. So, I am not sure of where to get spares in Osun. About the price, what's the make and model of your car? I have a friend I can call, he works at Automedics.
