Bummer on the plow truck! Hopefully you can get it up and running! Nice wheel choice on the Nali!! They look great in contrast to the body color! As far as the coolant issue check the heater core hoses at the firewall as the T connectors tend to get brittle and crack and then they can be susceptible to leakage.

Do the 100k service in your owners manual..I would also replace upstream O2 sensors at this time. USE ONLY OE PARTS!! Catch can is a good idea if you do your own maintenance. They do need to be monitored and emptied!! All they do is keep the intake system cleaner and reduce carbon build up on valves. Refer to owners manual for correct fluid types.

A little of both. Amazon had some good deals like AC Delco plugs and wires, Summit Racing had the best price(and in stock) the AC Delco water pump..... and there is one in town........ fluids and other parts local chain auto store
Be careful with Amazon and eBay “Delco” parts. Especially spark plugs. These are notorious for having counterfeit plugs. If they are super cheap, avoid them!

What does this switch do? I thought it was an ignition kill switch but doesn’t appear to be.

The only things I've done so far are;
-BOSS 10ACP touch screen w/carplay
-Oil Change
-Coolant drain and replace
-Inspect brakes
-New Rims and Tires (3 of the old rims leaked air and tires were at 30%...Got a set of 20" AT4's w/goodyear wrangles for 1k I think that was a steal.
does the stereo receiver work with the stock bose speakers?

Hey Y'all I just picked up an '03 Yukon Denali. I bought it in Burlington,Vermont but luckily its a California car that I saved from certain death by salt. It had 123k when I bought it and its got roughly 126k now. What kind of General Maintenance should I be doing? Tried to search but didn't have much luck. Any insight appreciated. Also any cool mods or tricks would be helpful. Thanks guys.
Looks kool, I like the ‘fire missiles’ and tag in the console. Wish I had some of the tags/pins from my time. Have to find a surplus stor. :)

If it says BOSE on the stereo then yes it should work, If not you'll have to purchase/install a bose interface module

Personally I swap out ALL my GM trucks to these 10" tablet touchscreen radios !! It sealed the deal with the family who bought my 09 Silverado lol

I have Bose in my 04. I just ordered Boss BE7ACP (see list of items in "What I Did on my..." thread). I decided to let Crutchfield figure out what I needed to make Bose and steering controls still work. Then, for $25... They will do all the connections between the new radio plug and the connector that goes to your vehicle harness. Worth not having to look at wires and trying to match up wire colors and making a bunch of connections. Plug the two ends in and 90% of the install is done! I should be getting it this weekend.

Agree. Crutchfield is great! And those wiring harnesses they make for your install.. :win:
