goatman I've always found the best way to bleed systems after working on them is to jack up the front of the vehicle, run it up to temp with the rad cap off and keep topping the system off as you squeeze the hoses working bubbles through. Also vary the rpms, you will see the bubbles come through the radiator cap and the level drop a little. Jacking the vehicle makes the radiator cap the highest point in the system.

Liftkit55 Thats whats Im experiencing now. New t-stat antifreeze is -20 degrees and low if any heat. So do I just pull the heater core hoses off and run water thru it with a garden hose

BAP same thing happened to me ,,,you may need to reback flush your heater core...assuming you flushed your system before you replaced your pump.

i had good heat before i replaced my water pump and tstat, after my replacement i lost all heat, i then back fushed my heater core again real good and now have great heat..

best of luck

nicks_yj Turn your hat on high run it cut the button if a 1 liter bottle off and tape it to your filet neck on the radiator and keep the bottle filed with the antifreeze mixture it should get rid of air pockets

barjeep i would say there is air in the way , run it with the cap one click loose for a little bit.
03-17-2013 06:35 PM
JD88 yes i just went and double checked there was only one top hose and one bottom hose
03-17-2013 05:47 PM
Redrider94 Are you sure you put the heater hoses on the water pump correct? If you reversed them you won't have heat!
03-17-2013 05:28 PM
JD88 i thought of that but its running up around 210
03-17-2013 05:21 PM
Kate Check your thermostat.
It may be jammed. Only costs a few bucks to replace it anyway, couldn't hurt.
