Facing the task of UIM/LIM replacement concerns me because of my inexperience working on engines, so when I wrote "dumb people" in the title I meant REALLY dumb people (me).
This tech info article http://www.bonnevilleclub.com/forum/...e=article&k=38
is very helpful, but I would like to clarify some points based on what I have read on the site from various places. I also think the article assumes a higher level of knowledge than I currently possess.
This diary was VERY helpful, but may have given me a false impression of the ease of this repair. http://www.bonnevilleclub.com/forum/...86&highlight=A
so here'* what I think
I have to do for UIM/LIM repair on a 96 SSE / L36:
1. Order APN kit for UIM and LIM gasket set GM 89017816.
2. Either order or have machined a new stovepipe. Order new elbow , make sure o-rings aren't flawed.
3. Order new 180 thermostat/seal/gasket (agrazela gave me a good list of what I might need at http://www.bonnevilleclub.com/forum/...ic.php?t=71440
4. Drain oil and coolant
5. Disassemble UIM and LIM. Remove alternator for easy access. In my case also remove valve cover since it is also leaking.
6. Clean, according to Bill Buttermore "use a tungsten carbide gasket scraper to clean the crud off gasket sealing surfaces, finishing with brake parts cleaner to degrease"
7. Reassemble with new gaskets in place and cleaned parts.
7a. There was a thread once about the importance of how many pounds of torque...I couldn't find that thread. Use BLUE locktight.
8. Refill oil and coolant (remind me: Are air bubbles/pockets an issue here and how do you avoid them if so? )
9. Start car while praying. Watch for leaks.
Where in this list is
A) an important point missing
B) places where an inexperienced person might make a small but fatal mistake.
I think step 7 and 7a above worries me the most and that'* where (B) is important
I really appreciate all the advice that will flow. My GXP payment forces me to repair the SSE myself. Such is life.
