Today I had a nice pin hole leak in my heater hose. UGH, 3/4 inch hose at autozone, fits on the pipe locate on top of engine but heater core pipe to hose fitting is lacking any snugness. So far so good.

Sheesh

Looks like I need to bleed the air out of heater core after new radiator. I did the fill radiator until fluid comes out, with engine off. I also filled the expansion tank to full mark. I will have to make sure I do it with engine cold so the thermostat is closed then goes to open.

 

Sometimes a bubble in the heater core can be coaxed to the surface by putting the nose of the truck up an incline, over a curb, on a ramp, etc., and running for a brief period of several minutes, heat on max.

If you keep hearing bubbles go by, that might not be a good sign....

 

I will do that. As for the "not a good sign" IT BETTER NOT BE WHAT THAT COULD MEAN.. *(GASP) I better not screw up my head gasket because I put in a new radiator because the POS from BP utah cracked.....

 

Here's slanginsanjuan's solution... works every time... won't hear any more bubbles.

 

But I need heat in Iowa..... lol I will do that for summer! I did get most of them out. I still hear it every once in a while.. But NOTHING like before. I drove it for almost 30 min and it didn't seem to be growing or anything. I will monitor it and bleed again? I jacked the battery side up and opened both radiator and expansion tank caps. It was elevated by 1 ft.
Bubbles did come out, but not all of them. Suggestions?
