Hey guys so the heat in my truck isnt working anymore after i replaced the tstat, waterpump, and manifold gasket.....from what ive been researching is it seems likely their is air inside my heater core..i just want to make sure this is how to bleed the air out

Jack up the passenger side
take off the rad cap
let the truck run
wait till it "burps"
turn off engine, fill
repeat if neccesary

is this correct?

 

Can you hear the heater core making noise from air bubbles? Feel both heater hoses, both shôuld be pretty warm. If not heater core could be clogged or the control valve is bad. If you haven't recently done work to the cooling system and the cap is good (as well as sufficient amount of coolant) then there shouldn't be air in the system...unless head gasket is blown, although unlikely

 

that is exactly what im hearing, i couldnt think of how to describe it! haha, but like i said i did do work to it recently(wp, tstat, im gasket)..where is the control valve? how do i know if that is bad

 

The truck doesn't have to be jacked up. Everyone makes it out like bleeding the air on these trucks is a major undertaking that involves building a Rube-Goldberg device that will somehow lift and tilt the right front portion of the truck at a 15º incline with a -30º tilt.

Fill it with coolant, leave the cap off, start the vehicle and get it running to operating temperature, watch the coolant level and fill it until it no longer drops.

 

^^^this. Then check it everyday and top off as needed for a few days. Driving it will help purge the air out.

 

aight cool thanks for the help!
