Figure I might give this try. Maybe it will turn into a maintenance build thread. Sounds Like a Plan
Starting out un-traditionally, its a repair.
Here in Texas, we got a cold front for a few days and just my luck, no heat! Not sure who I want to blame, but I definitely glad this forum exists. I thank those whom share experiences, knowledge, and still managed to post. Its the reason why I have a love/hate for this platform sometimes.
So dealer was a no go for me. Quite the few reasons why, but mostly, warranty ended back in July this year @ 55k miles. Plus there is another story in between with them. So I took it upon myself to figure out why no heat.
Coolant levels, good.
Dead cold consistent in the cabin, so it didn't seem as if there was air in the heater core.
Temps appeared ok (learned a few things). Factory gauge, useless. The Banks iDash came in handy.
Top radiator hose cold.
Thermostat stuck closed.
I replaced one on my last gen. It didn't seem that difficult, and fairly straight forward. Yea, no GM. What a PITA!
Some things to note in order of removal
Not a lot room to get a breaker bar for the tension pulley to then remove
Charge pipe
Throttle body
Fuse box
Alternator
Unbolted the AC compressor and slide it over.
Unbolted EGR assembly to temporarily remove just the EGR cooler. It will go back on.👮♂️👮♂️. Hold your horses.
Then comes the hose.
All this work to access 2x 10mm bolts to replace a $150 part that is hidden under the intake manifold, bundled with an ungodly amount of hoses. Small hands is the advantage here, fiddled those nuts, bolts, and hose clamps. Seems like they all each needed a special tool to remove.
Still going at it tomorrow, day 3 since I ran out of light. Who should I thank/blame for working on my Thanksgiving day. Some one tell me I went about this wrong,
