Replacing common problems
I've decided I'm going to replace my LIM gaskets, UIM gaskets, and UIM just as insurance (it'* leaking slightly out, but no coolant in the oil, and I'm pretty sure by the manufacture date that the UIM is original).
So far, I'm going to get the aluminum LIM gaskets, the coolant elbows, new coolant hoses (mine are 10 years old), new thermostat and gasket, and obviously new UIM and gaskets. Is there anything else I should look for while I'm in there?
Also, I heard rumors of an aluminum UIM (although I don't believe it). Is my best bet to just buy the plastic replacement from GM? Are there any other performance parts I can get in while I'm in there? Should I buy the stock coolant hoses from GM or should I seek a non-OEM alternative?
Now, my friends and I have a basic understanding of engines, and can probably get this done in one day by troubleshooting (and with some cheap beer), but are there any tips and things I should watch out for, or tools I should pick up (besides the ordinary stuff).
