Thermostat removal, people who've actually done it or have experience, reply.
My car has been overheating, i'm thinking it's possibly due to a sticking thermostat, i'm wanting to remove it entirely. I'm wanting to know the positives and negatives of doing so, i've searched and didn't find too much.
I know how to do it, i'm wanting to know the negative side effects and positive effects.
I'm reading that a thermostat always open can cause overheating as well. I don't know if that's theory, or truth.

It can by not allowing cooloant to cool down before bing cycled back into the motor, unlikely but plausable.
I made a thread a while back about peoples cars over heating search under my name and it should come up.

Why replace something i can go without? Just more **** to fail.
I don't need walked through it, i can remove a thermostat on my own.
I found your thread noc, took me searching for "Overheating", for some reason it didn't find "Thermostat" in your thread.

I removed one once, I had to cut the thermostat itself from the housing because the housing holds the gasket. Car took slightly longer to reach operating temperature, but only about a minute longer.
Yes, it will take longer for the coolant to warm up since it's being circulated. It's good to have a thermo in the ***-freezing weather but if you let the car warm up before you get in it, you'll be fine.
It allows your car to reach it's operating temp a lot quicker in the winter time (less wear and what not)
Also it moderates the temperature the engine runs at. On the high way you might find it runs cooler. Whether this is bad or not you would have to do a lot of research. Again if you drive in a colder winter climate you might find that your car just won't heat up. I am sure Honda designed it's car to run at a certain temp, changing that by a lot is most likely bad.
IMO I would just replace it.

I don't drive the car in winter, it goes into storage. Running colder would be a good thing for me, less prone to detonation, i guess the Jackson Racing SC kits come with a 160 degree thermostat.
removing the thermostat is not that bad anyway... i had a friend who wouldn't use coolant at all.. he would use water... it would turn to steam shortly and he would throw a buck of water again... he didn't care for the car and drove it like that for a long *** time... it was buick though.. they take that kinda abuse

No theres more, I would say the worst is wear. You need your pistons and rings too heat up so they expand and conform better to the cylinder walls, they don't fit as well cold(causing wear) and will cause blow by( exhaust gasses seeping through rings during compression).
It will hurt your fuel economy since till you reach your predetermined operating temperature you will stay in open loop and your car will spit out a lot more gas.
Your oil will turn to sludge a lot quicker since the heat of your motor is used to evaporate condensation in your oil pan.
I personally have not experienced overheating in my civic from the one day I didn't have a thermostat, but in my MKIII I have when I was doing a 4 hour trip. Don't quote me but I thinks its because your radiator fluid doesn't have time to absorb the heat from your motor when the coolant is moving too fast.
Its only 15 bucks and there is always a reason why car manufactures put something in a car. I would get one if I were you

I was pretty much gonna say exactly what you said. The prefered operating tem for a car is 225 i believe. If its below that then the car will have performance issues. I would think there would be a really good reason for a thermostat or else they would have gotten rid of it.

Yeah I think some cameros are around 225 and I think my civic was around 185-195. It just depends on how the motor is built.

I don't have a heater core anyway.
The "Wear and Tear" shouldn't be a huge issue for me, i always let the motor warm up completely before driving it.

Water pumps are lubricated by the coolant, so running straight water through your coolant system is a lot like running water through your engine instead of oil. And Buicks are no more built for such abuse than any other car. Just because it has an iron block and head(s) doesn't mean that the wanton disregard will be absorbed any more easilly. Your friend is an idiot.

A hot engine is no more prepared for operation than a cold one. Warming up your engine is only good if it thins your oil to operating range. You can drive a car like you hate it on a hot Summer's day if the oil pressure is reading around 15-50psi, or, alternately, you can wait 30 minutes for a car to warm up completely on a Winter's morning and the oil pressure in it is still at 80psi.
"Warmed up" is not supposed to regard coolant temperature: it's supposed to describe the oil's ability to circulate within parameters.

Yeah but you never really stay at a constant teperature. If thermostats were like $100 then I could see why but there pretty cheap, and you never know maybe there is some other problem besides the thermostat. Either way do what you want its your car.
