Disconnect the heater hoses from the water pump and the intake manifold. Get a compressor and blow out the hose (put the air hose into the the hose that came off the mainfold. then flush the system and replace the antifreeze.

SOURCE: replacement of coolant temperature sensor

located under intake in water crossover pipe,you can access the sensor by removing intake chamber box,then pcv hose connected to the block,the connector is orangeish 2pin,use a 19mmdeep socket on a 3/8 ratchet to get it loose,make sure engine is cool,also make sure there is a new brass washer with your new sensor,sometimes the old washer comes off when removing the sensor,sometimes it sticks to the pipe,some coolant will escape so make sure to top it off

If you are getting the low coolant message you are looking for the coolant level sensor not the coolant temp sensor. I do believe the sensor is in the jug, is it filled to the full line?

The truck stalled out when driving. Sounds like it wants to start, but won't fire. Codes found - P0410, P0128, P0141, P0102. Please help. Daughter's truck and she leaves for college in a few days.

code p0410 refers to secondary injection system--malfunction===causes wiring--air valve--air solenoid--- ECM
code p0141 refers to heated oxygen sensor-2 bank1-heater control -circuit malfunction===causes --wiring--oxygen sensor--ECM
code p0128 refers to coolant thermostat --coolant temp below thermostat regulating temperature==causes mechanical fault (thermostat stuck open)
code p0102 refers to mass air flow (MAF) sensor/ volume air flow (VAF) sensor low input===causes wiring short to ground--MAF/VAF sensor ECM

I have a 97 GMC Jimmy that keeps trying to overheat. We've replaced the water pump and the coolant temp gauge however its ranging from half to 3/4 temperature. Is it possible that a sensor could be...

It could be a few things - stuck thermostat , bad sending unit , bad gauge in
the dash.

I would HIGHLY suggest going to a parts store and buying a Haynes repair
manual ( about 25 bucks ) before you do anything else.
It will give you step by step instructions / diagnosis on this problem and a whole lot more !
Well worth the money.

I have a 2005 gmc jimmy, the engine light is on and i hooked up my code reader and it says Coolant Temp Below Thermostat Regulating Temp. What does this mean and how do i fix it?

your thermostat is designed to open at a specific temp, for example a 195 thermostat is supposed to start opening at 195 but will not fully open until it reached about 210. Your ECM has determined that your thermostat is not 'closed', but is hung open, not allowing the engine to reach a temp that the computer is set to see. So the thermostat is either malfunctioning, or your temperature sender unit is reporting the wrong thing to the ECU. Probably a good time to replace the thermostat, if the condition persists, replace the sender unit-both items together will cost less than $30 total.
