NOSNUSE said:You should always run a thermostat in your car, this helps not only warm the engine up, but also allows the coolant to cool off. In an emergency just drill a couple of holes in the thermostat until you get a new one.
DSMRevolution said:I think you could actually overheat from driving without one. The cooling system will not be doing its job and with coolant just free flowing it gives it no time to cool down. If it does not cool down eventually it will keep heating up until BAM! Really hot antifreeze! Ok sorry that was getting lame, but true that your cooling system will not be doing its job. I would get one in asap.
crazyjoe said:? You obviously don't understand how the cooling system works. When the thermo is closed, the water in the system is circulated through the engine only. When it's open, it goes to the radiatr to col down. If it's not there, the radiator is ALWAYS cooling the coolant, so you will run cooler, never hotter.
It's not a good idea to do long-term, since there is a reason your car has a 190 degree thermostat....the engine runs at its peak efficiency at that temp range. Any hotter and you can do damage, any cooler and you run rich.
DSMRevolution said:Um no how about back to you because I DO understand how a cooling system works. Think about it, it is common sense. If you have no thermostat and you have coolant running through the block, head, radiator, heater core etc without the thermostat closing then what is the radiator actually doing? Well not much because coolant does not sit in the radiator long enough to actually be affected by the radiator fans and "wind speed" cooling. When the thermostat is closed it is circulating through the heater core also, not just the engine. If it's not there (thermostat), your radiator is NOT always cooling the coolant so you will eventually run hotter. Any hotter then 190 and you will not do damage, but any hotter then 220 you might do damage. On some cars, the radiator fans do not even kick on until the coolant temp sensor sees 227 degrees. Not sure on a DSM what temp, but I am sure I could check on my logger. Hotter engine temp - Better gas mileage and less performance. Cooler engine temp - Worse gas mileage but more performance. Why take the chance of warping something because you have no thermostat and every engine component is running at a different temperature? Spend the $5 and replace the thermostat.
Yeah, pretty much everything since 1932 has been pressurized.CorrupTTalon said:so is it whats called a pressurized system?
