Thermostat housing

[tepes]

well i did it now...

our 91 3.4 cutlass developed a minor drip off the thermostat housing, the line next to the thermostat, which in turned dripped onto the exhaust instantly turning to stinky coolant fumes.

i thought maybe the lil ring seals inside had gone bad, so i pinch the 2 plastic peices together and pull, and the damn aluminum connector breaks in half, i didnt even grape ape it, just a gentle tug.. and of course the thread portion is in the thermostat housing!!!

here i am with my proverbial **** in my hand and the wife is making quite a sport of me..

so i go and get the super duper official GM coolant connector removal tool, tap it in and grab a socket to take out the thread portion thats stuck in there, and sure as **** it just turns it to powder with every turn.

so whats my options guys, the threads arent really damaged, just filled with whats left of the hose connector...

if the damn wife teases me once more its gonna get ugly i tell ya

thanks in advance

Ahhhhh, yes. The dreaded "heater nipple", only this is one nipple nobody wants to suck on. In my box I have a large easy out and other stuff to dig out the old material as well as a pipe thread tap to restore the threads. Some guys change over to a brass nipple and do away with the quick release (yeah, I laughed too when they said that) nipple. Still others are purists and simply replace it with the original design. These are also a headache in every application they are used in. Good luck.

yeah lookin like ima have to scribe out the chunks of the old "nipple" ( hahaha ) thats left in there, and then clean the threads up a bit, good lookin out on using a brass fitting for ease of removal down the road.

much obliged my man
