I just got the head redone, and also installed a new fan clutch, thermostat, and water pump. It's still getting super hot. Any ideas what it could be?

I know this is a basic question, but always a great place to start...are you sure there are no air bubbles in the cooling system? With all those items replaced it's quite possible there is air in the system.Originally posted by blunttech -
whats a good way to bleed it cause its still getting hotComment

You need to get the front of the car jacked up, or park facing up a hill. Use the small hose that goes from the radiator to the reservoir as a bleed valve. Start the car, rev it up a bit and wait for it to start warming up. You should have the heater turned up to full hot, and the fan on all the way. As it gets hot, pull the small hose back a bit of the radiator. You will probably see bubbles. Keep doing this until you have coolant without bubbles coming out.

i just took it to a shop and they said it could be the water pump but its new or the thermostat but its new i bought it from them. they said im not getting go flow because the top hose is hot but the bottom is cold even when at running temp so what could it beComment

Hot top and cold bottom suggests that you have either a bad radiator or a bad water pump. A bad thermostat would mean a cold top hose.2006 GMC Sierra 2500HD 4WD LBZ/Allison
