    Overheating

    As far as refilling the coolant with as little air as possible here is what I did. 1. Since the thermostat and housing is off I started to fill from there till it was topped off 2. I attached the radiator hose to the housing and left it elevated 3. I slowly filled reservoir up till it ran out of...

    Here yeah go. For the guys who do not have a lathe ( I used to be a machinist) just take a cut off disc on a 4" angle grinder and that will work good enough. Then use a dremel with a stone bit and deburr the socket. Cut the socket to roughly 1 3/4 over all length. A little shorter is...

    ALL DONE!!!!!!!!!!!!. Took truck out for hour drive and all is well. So that sensor was the problem all along, and the trimmed socket worked great for removing it. Thanks everyone for all the help guys.

    Great news boys, You do not have to remove your intake manifold to remove sensor. I took a 19mm 3/8 drive socket and turned it down to OAL of 1.700. That now allows me to have a universal attachment on the socket along with an extension. That saves a bunch of time.

    Update, It may be possible to change the sensor without removing the intake manifold by removing the sensor with a flex head wrench. I have every tool but that one so I will be purchasing one tomorrow

    Watch the youtube vid. It shows how to remove manifold. Did you take an ohm reading on the sensor?

    And the results that everyone has been waiting for.........Drum Roll Please.............. My calculations were in done in ambient temperature instead of operating temp IE 194 deg A proper ohm reading at 194 deg is K3.7 ohm's My new sensor at ambient temp of 62 deg f is K26.6 ohm's My...

    I only used the other one for testing. I am definitely putting in a new sensor

    Overheating

    I am 99% sure the sensor is bad. I swapped out sensors again, and with the old one the vehicle has problems starting and the temp gauge is half way. With the one from the other block, the temp gauge is at its lowest point and it starts right up. The sensor must send a signal to the pcm to adjust...

    ok, will do that tomorrow

    OK, I lied. I had a little energy left in me. I plugged in the sensor from my other motor and the temp gauge went to low where it should be

    I will try this tomorrow. I still have the old motor and can get it off the old one

    Overheating

    So here is what I did.......... 1. Removed thermostat 2. Took off upper radiator hose and forced water through the hose back to engine 3. Did this for about 10 min while water ran through upper radiator hose connection 4. Quickly buttoned it up as not to lose to much water. 5. At this point we...

    Overheating

    dammit...Radiator is fine. As I filled it from the top it flowed now problem through the bottom. Back to the drawing board,,,,Has to be air somewhere..Also checking wiring like you stated Roxy1225

    New code...P1289, I'm researching it now.

    There still must be air in it somewhere..

    Overheating

    As far as radiator blockage goes, could I just remove upper and lower hoses, put my garden hose in upper and see how it flows out the lower?

    Overheating

    ok..more to report. When I disconnected the temp head sensor it would run fine only for maybe 10 sec and then die but the red warning light was lit for the low oil pressure/ high coolant temp. I sprayed electrical cleaner in the plugs and reassembled it. The truck now starts as before with all...
