P0128 came back after replacing t-stat


code p 128 refers to coolant thermostat---coolant temp below thermostat regulating temperature ====causes --mechanical fault
you say that you have replaced the thermostat and it is just under 210 F which is 99 c or almost boiling point
you will have to investigate why it is running so hot.
check that you put the thermostat in correctly ( bulb section to block/head water
Next point --the codes are originated by the coolant temperature sensor ( puts the fans on and sets the ECM fuel/air ratio for the engine ) so to get it off you will need to reset with a scan tool

How to replace thermostat in 1999 volvo


Don't just change just the thermostat... change the sensor located in the thermostat housing (if your engine is overheating). The whole works is located inside the timing cover. Sockets: You'll need a 10mm for the timing cover and the 3 bolts on the thermostat cover, and an 8mm for the sensor harness bolts. Then you'll need a 3/4 open end wrench for the sensor.

How to install a cooling temperature sensor


It's located 2" above the thermostat, you might as well replace the thermostat while you're at it, they're cheap and will fail if it hasn't already been replaced a time or two. Must remove the alternator and bracket to get to both. Obviously, the coolant needs to be drained to do either. The thermostat has 2 bolts that come off, that's easy. The coolant sensor just unscrews from the block. But remember to disconnect the wiring, just a clip. Save yourself the frustration, and remove the alternator and bracket. Take the serpentine belt off by using a breaker bar and taking a 3/8" extention and sticking into the square 3/8" hole in the tensioner. Turn the breaker bar clockwise and remove the belt. Good luck!

Where is the thermostat on a 2005 impala 3.4 and how do I replace?


Your thermostat is located inside the thermostat housing at the end of the upper radiator hose, on the back of the engine. Just find your upper radiator hose and follow it to the engine. It's hooked to the thermostat housing. easy... now comes the fun... To replace your thermostat, you have to remove the air intake duct (which mean unplug all your sensors on it, MAF etc). That should give you better access to the housing. You still have the throttle body right above the housing, and you may have to remove it too for better access and that sucks...(it involves disconnecting some coolant bypass lines...make sure you drain your radiator before you do so) Once you have that done remove the thermostat housing (after you unplug the coolant temperature sensor) and have some towels and a bucket ready as coolant will be coming out of it. Remove the old thermostat, remove the old gasket if necessary, and put the new thermostat with the new gasket in there (with the spring pointing toward the engine). Put some RTV sealant on the housing bolt it back on there, and put the throttle body back as well as the air duct and all the sensors. Refill your radiator, turn your engine on and check for leaks.

Trying to find out where the temperature sensor is located or maybe its called a switch temperature sensor. I replaced the thermostat and I was told this need to be replaced too


You would only need to replace this if your temperature gauge is not working properly. Just because the thermostat was replaced does not mean the sensor must be too.

There were three different engines offered for that vehicle and there is a separate temp sending unit for the gauge than there is for the computer(PCM). The V6 4.0 SOHC ECT for the PCM and the sending unit for the gauge are both located side by side on top of the thermostat housing. The V6 4.0 EI engine ECT is located on the front of the engine, left of the throttle body, and the sending unit is located in the front of the engine, behind the alternator bracket. The V8 5.0 ECT is located in the front of the engine, below the middle of the ignition coils and the sending unit is in the same area, but toward the driver's side of the engine below the left ignition coil.

It will look similar to this...

Tempature gauge quiet working emission test said it was engine tempature control and i need to know where its locared


The temperature sensor in located at the thermostat housing under the throttle body. You'll see two wires going in to the sensor, make sure the wires are not damaged and still connected. It's rear for the sensor to fail but it's an easy fix to replace it, just disconnect the wire harness and unscrew the sensor with a deep socket and replace with the new sensor in the reveres process. Good luck and hope this helps.
