Default What else to do?? when doing LIM/UIM

Is there anything I should replace while doing the LIM and UIM? UIM was done @67k by a daeler we now have 170K and the LIM is going. Plugs done around 130K and wires. I will drain all the orange coolant and go green.

Change the oil too. You will also need new fuel injector o-rings to keep vacuum leaks at bay.

I was thinking of more in the line of maintenance things.
1. Dorman UIM kit
2. LIM gaskit GM or Fel Pro

For you rLIM gasket be sure to get the aluminum framed gasket, not the OEM plastic framed gasket. The plastic ones start to fail in about a year.

If your valve covers are leaking, it would be a good time to replace them seeing you will be right there. If your serp belts are looking old, again, your right there, may as well change them. Are your plugs and plug wires old? Guess what, your right there with all kinds of room.

I wouldn't green coolant it. All that green is ..is a coolant that wasn't designed for your system and won't lubricate and have the right anticorrosion properties necessary.

An Anycolor would be a much better choice.
