What kind of maintenance have you had done since you have had it?
Take a look at your manual and make sure everything that is scheduled for 100k is done. Also, anything that was scheduled prior to 100k but didn't get done, get that done as well. In particular, change the plugs with AC-Delco model 41-987s gapped at 0.050" and drain and refill the coolant using a 50/50 mix of DexCool and distilled water and make sure the correct coolant supplement gets added to the radiator hose and NOT THE SURGE TANK.Rolnhrd said:Hey guys. I have a 01 DTS and my waranty will be up soon. She has aprox 100,000 miles and I wanted to know what kind of work should I have done at the stealer! Oh by the way I have a friend that works there :stirpot: if you know what I mean. A list of anything you can think of that would take a s--t with this many miles. Thank you for your help
