yup, i had a leak starting from the very same freeze plug. i thought i smelled coolant, but never saw a leak. the tech that replaced my tranny saw it before it got worst.

 

Ok I did as you suggested and shell it did was the fluid level rose and ran out over the filler neck. It only had 20-30 small Bible come out. It didn't burp out a lot of air and hey didn't get any better. Should both the to and bottom radiator hoses be hot? The top one I know should be and is and the bottom stays cold. Of the two heater hoses the passenger side gets warmer than the driver side but I can feel the driver side is a little warm.

 

Agreed.

 

Back flush the heater core. With both hoses disconnected, point them both up in the air, and fill the core from the longer hose till fluid runs out the shorter one. Clamp them both off, and hook 'em back up. (trying to lose as little fluid as possible.) See if that doesn't help the situation.

 

All is good now. I did as you suggested however my hose was not long enough(that's what she said), so I used a low pressure of air and then poured water in. Heat is good and hot after about 3-4 mins of idle time and the temp gauge is now getting back to where it used to be(closer to the edge of the 210 mark). Thanks for everyones input.

 

Ive been fighting this same issue. google heater treater. Best fix ever

 

That only applies to the 99 and up trucks. Previous years had a cable operated temp door.
