    i've installed bigger cams, injectors, throttle body and plenum, headers, exhaust, 3:73 gear, underdrive pulleys, etc. so i installed a 180 deg thermostat to try to help it run cooler mostly around town. with all the performance parts and running underdrive pulleys i thought that would help. wasn't sure whether or not to change fan settings with tuner or just leave stock fan settings?

    Your computer is calibrated to operate all systems at 195 degrees. If you run the engine colder, it will throw everything off. (fans are your least problem then)

The computer does all that. all you are doing by changing the value of the thermostat is having it open alittle sooner than later. not a prob.

How do i change the coolant temp sensor in my 2005 toyota prius

I have a 2004 Prius and have a scan gauge. I constantly watch engine coolant temperature. I noticed it being very erratic in the summer (going up to around 180 deg F and then falling back to the 160s then back up again).
I decided to replace the thermostat hoping that this would solve the problem. It did not. Now that it is winter and very cold, the coolant temperature never reaches the thermostat temperature (82 deg C or 180 deg F) and is struggling to get above 150 to 160 deg F for trips > 10 miles. I have blocked most of the radiator and still the same problem. MPGs can get in the low 40s for longer trips (> 10 miles), but for short trips they are in the mid 30s (1-3 miles). This is on the low side for what I have gotten in the past. When the engine temperature is erratic, the combustion efficiency suffers because of uneven temperature in the cylinders.
I have noticed the cabin heater is erratic at times as well. Great heat some times and at other times moderate heat. I attribute this (obviously) to the coolant temperature swings.
Also I have not heard the storage tank coolant pump run after I shut off the car during cold weather.
Would the issue be the coolant control valve? I have had no error codes set at all (specifically P1121). If it is the coolant control valve is the a test procedure to make sure this is the issue? Also are these covered under recall like the inverter coolant pumps were?
Thanks and I look forward to hearing your thoughts.

I think you mean 3.9, stock is 195 but you can also use a 180.

I have a 2002 silverado and i just replaced the thermostat in my truck but its still operating at 200 degrees. is this normal or should i look further into it? and if not what might be the problem?

It runs a 195 degree thermostat, not to worry,normal operating temp.
Gm says they are more "GREEN" when the temp is up,can't change the thermo to a 180 because the computer is set for 190 to let the fuel trim from the o2 sensors to help with mileage
You may find it runs cooler with the AC on due to the electric fan running.

Where is the temperature sensor located on a 2002 hyundai accent

okay temp is not hot enough check thermostat temp rating is it 195 degree etc. are you in a cold climate state? Maybe you need to get a thermostat of a hotter degree[four seasons 195 degree should do it]. If this is what you have (195 deg. thermo) then it might be stuck open not allowing the heat to build up. Another possibility is air in the radiator system, bleed system. This too might be of help the blend door, which is operated by the HOT to COLD lever on your climate control panel, might not be moving all the way closed to stop the cold air from coming in the mix area with the heat. Move the lever back and fourth to feel any change in heat with your hand. Put the defroster on fan on high and put one hand near the defroster vent thee other hand moving the temperature selector. Do you have some sort of heat and you can feel the difference from hot and cold, then my recommendation is to check thermo degree rating, if ok then try to flush radiator, and if that does not work --replace Heater Core. Thank you for allowing me to help you if you need me just write,Lee

Temp runs only 180 degrees. High temp thermostat

yes thermostats wear out. make sure your cooling fans are not running at the low temp you have. you may have a bad temp sending unit. also you gauge send ing unit could be bad.

Running hot

You either have a head gasket problem or the
coolant system wants bleeding as air is being trapped in it .
Take out thermostat and try bleeding and driving without it in if ok then try the old one or a lower temp one

Let me know how you get on Ron.

What is the most i can safely advance ignition timing on a 2002 ford mustang gt 4.6L 2V?? it is at 30 deg. now.. i have changed the cams, which have the same lift as stock, but more duration, this may or...

How are you planning on adjusting the ignition timing? With computer programing or moving the cranksensor. You should be o.k as long as you don't get spark knock. Are you checking this with a timing light or a scanner?
