installed 203 thermostat but now have question

[bck4more]

Ok so i installed my 203 thermo plus new waterpump but im kinda wondering whats going on now. I started my truck let it run for about 15 mins then go for a drive of about 10-15 mins stop for like 10 with letting it run then about 15 mins back home and i got out to check for leaks and whatnot well neither bottom or top hose is hot or running any fluid through them. I have heater on and let me tell ya it will run you out of the cab. What is going on here guys?

is it possible something is airlocked?

I dont have a clue. I am able to open coolant holder and never hear that its under pressure and its full.

sounds like you got alot of air in the system

[bck4more]

If thats the case now can i get the air out of it?

a steep hill with the cap off worked for me but there are numerous ways to do it, hi idle w/ the cap off, drive it for few miles pop the cap then drive some more, i'm sure others will chime in.

I just drove mine. Kept putting coolant in it for a couple weeks.
