I am not 100% sure, but the temperature gauge in our car....is that the water temp or what?

its for your engine temp. not water, it might measure the water temp or somehow be involved with that but it measures the engines temp.

engine bay temperature i believe.

Ok so engine temp.....is that the cylinder temp, or what?

That is your coolant temp. Engine bay temp...LOL. Man...It is supposed to be the temp of your engine, but it is measured using the thermostat, which measures the temp of the coolant. So, in effect, it is the temp of the coolant inside the engine, not in the radiator.

That is correct!

I second that motion and raise you 50. That was the best laugh I've had all week!

If you really wanted to know, call the service station and ask. I'm sure the local dealer can tell you.

So if you want to lower the temperature in your engine bay, just had a hood vent. [IMG]i/expressions/laugh2.gif[/IMG]
That was a good one.

it's your water (coolant) temp. engine bay temp, hahahaha. that's awesome. so if it was really really cold out, your temp gauge wouldn't ever warm up? LOL. oil temp gauges are another measure of the temp of your engine. i never really understood the need for both.

It measures how full of hot air all of the "fakers" are who claim to have a turbo in their 7th gen [IMG]i/expressions/face-icon-small-wink.gif[/IMG] .

But luckily there are a handful of "non-fakers" out their that help to regulate that temperature .

Well, the oil temperature is important, because as the oil heats up, the viscosity (thinckness, sort of) breaks down, and it's performance as a lubricant is reduced. At some point the oil becomes uselss as a lubricant. Then you can have severe damage from the friction of metal parts wearing on each other. Think of the oil in a frying pan... it starts thick, then thins, then burns...

The coolant on the other hand works in the capacity of dissapating heat from the engine block and maintaining as steady a temperature as possible. Again, if the coolant boils off due to leaks, high temp days or what not, then you again run the risk of over heating the engine. This can cause the oil to work at higher heat and break down. So, in a way, the coolant helps the oil cool, and the oil helps the mechanical, metal parts work with a reduced level of friction.

My engine runs a lot cooler now than when it was stock, my xenon front bumper lets more air to flow through, and I added a Mugen High pressure radiator cap. I am thinking of getting this stuff called purple ice I think to add to the radiator.

coolant temp isn't measured threw a thermostat, it's measured by a CTS, coolant temp sensor. your thermostat just opens and closes to regulate coolant flow threw the engine to keep a steady operating temp.

you know you don't want your car to run too cool. if you never reach operating temp then your computer won't listen to your engines sensors and it will run on pre programed setting. when that happens you'll constantly be running rich, and running rich is pretty bad for your engine and will destroy your cat.

That's true. The thermostat regulates the flow of coolant as it leaves the engine, but it is based on coolant temperature. It is closed when cold and varies in openness until ideal temp is reached and then it is wide open.

Also, that's true you don't want your engine to run too cool. The coolant actually allows a better transfer of heat through the metal when it is at a higher temperature. Also, if the engine is hotter, it allows a better combustion of fuel, and the less viscous oil allows a smoother, more fluid movement of mechanical parts.

very good, also oil temp is especially important if you have a turbo that runs off engine oil rather than its own source, turbos have a knack for cooking oil when they are run really hard then not given time to slow back down (a turbo can freewheel for a few minutes after engine shutdown depending on how hard the run was)
