thermostat replacement

Hello,

The thermostat is located at the end of the upper hose toward the engine.

Here a video on the job.

Here is a guide that will give you an idea of what to do as well.

Here are some diagrams to help you see what I am talking about for your car I have included both 4 and 6 cylinder engines just in case some one else needs them.

Check out the diagrams (Below). Please let us know what happens.

bad thermostat in my car, live on hot climate, should i remove it for good?

in order for your engine to run efficiently the computer must recognize a constant operating temperature removing the thermostat might keep the engine "too cool"---the computer might remain in "closed loop" this is sorta a quick explanation of the loops there are two "loops"---"open" and "closed" open means the sensors are giving the computer "real time" info, example: o2 sensor is telling the computer the oxygen content in the exhaust so it can adjust the injectors to get the most efficient "burn" possible being that it takes a little while for the o2 to warm up to "transmit" info...how does the engine run? same goes for "temperature sensors---it must get to operating temperature before it is "sensed" by the computer the engine runs "closed loop" during the time it awaits for sensor to "come on line"---which means the computer has "preset" values programmed into it--it runs off of them, until all sensors come on-line.....closed loop sorta means, the engine components are "fed false info", that will make the engine run---this "loop" is not efficient, usually you will notice it runs rich--mpg goes down!

this is not only true for the o2 sensors, but other sensors not working will cause this (staying in closed loop)---closed loop is basically "default"

"open loop" is when the computer runs the engine off of "right now!"--"real time" information----basically the present environment is being sensed by the computer---barometric pressure/ oxygen content in the fuel/ engine temperature/ air movement into the engine/ etc...etc. with this info, the computer does not rely on "preset/ default" information to make inefficient "fuel decisions"----it can now use the "present environmental info" to make efficient fuel decisions giving your vehicle peak performance

Do you have to have a thermostat? Will it run hot with out it?

Yes you should have the thermostat in, you can run it with out thermostat too, but the issue is that will run rich using a lot of gas and it will effect the emission system.

removing it will not cause car to overheat. it should run cooler in fact. in warm climate it should not cause excessive gas useage.
